7 SMM54 2. BEFORE STARTING THE LAWN MOWER 2.1. Set up an operation plan with sufficient time allowance. A tight plan may result in unexpected accidents. Especially when operating the lawn mower under extremely hot, cold, or humid circumstances, set up an operation schedule or method which will ensure operational safety Mow only in daylight or good artificial light. Mowing in the dark may cause unexpected accidents Thoroughly inspect the mowing area and remove all objects from the mowing area that the lawn mower can throw, such as stones, toys, sticks, and wires, which may lead to serious accidents Ensure that there are no people or pets in the area where you will mow. Keep children out of the mowing area and under the watchful care of a responsible adult Do not operate the lawn mower unless the operator s presence controls, safety switches, and guards are attached and functioning properly Start the engine from operator s seat Before starting the engine, make sure that everything is safe around the lawn mower and put the traction drive in neutral, apply the parking brake or parking lock, and disengage the cutting unit(s). Otherwise, unexpected accidents may occur Start the engine with the starter switch only. Never attempt to start the engine by shorting the terminals, or the lawn mower may move abruptly, and result in unexpected accidents Do not run the engine in an enclosed area where dangerous carbon monoxide fumes can collect. Sufficient ventilation should be provided when starting the engine in an enclosed area Make sure of safety around the lawn mower and move slowly when starting. Abrupt starting may cause unexpected accidents Become familiar with the operation, particularly, the stopping of the lawn mower. You should be skilful enough to be able to stop the lawn mower at will Use only attachments and accessories approved by the manufacturer and install and operate them as directed. FIG. 4 6

8 FOR SAFE OPERATION Be sure to operate the lawn mower equipped with a standard mower deck and collector. Never mow grass without the collector, or the lawn mower scatters grass, stone and other flying debris, which is very dangerous. If you would like not to collect the cut glass in a collector, equip an optional discharge cover for collector. Discharge cover for SBC550XL ( ) pc Discharge cover for SBC600XH ( ) pc When your lawn mower is equipped with an implement other than a standard mower deck and collector, never fail to ask your dealer about machine balance. Always follow their advice Keep in mind that the operator or user is responsible for the accidents or hazards caused by the lawn mower to other people or their property Inspect the lawn mower for wear or damage. Replace any worn or damaged parts Especially before starting the mower, be sure to perform advised pre-operation inspections especially on the brake and inspect visually to see that the blade and blade tightening nuts are not worn, damaged or loose. Replace worn or damaged blade and nuts as an assembly to preserve blade balance. Otherwise, poor braking or scattered broken blades may result, which is very dangerous. 7

9 SMM54 3. OPERATION OF THE LAWN MOWER 3.1. When the lawn mower is running, stay away from the discharge opening, the cutting unit(s), and all moving parts During operation, never allow anyone, especially children, and animals to be in the vicinity of the lawn mower. Do not direct the discharge at anyone When you are working with coworkers, be sure to alert them by signalling before you take a new action When operating the lawn mower, you should be seated in the operator s seat properly, hold the steering wheel by both hands, and look in the direction in which the lawn mower advances. Avoid looking aside or holding the steering wheel by one hand during operation. FIG Always be sure to operate the lawn mower from the operator s seat. Never attempt to get on or off the lawn mower while it is travelling Do not mow on wet grass. The lawn mower may slide Slow down before turning the lawn mower. Turning at high speed may cause the lawn mower to turn over Never attempt to depress the differential lock pedal while turning around the lawn mower. Turning with the differential lock on may cause the lawn mower to turn over Look down and behind you and ensure a clear path before you move the lawn mower backward Do not mow while moving backward unless it is absolutely necessary Never operate the lawn mower in terrain where there are ditches, holes, or steps easy to collapse. In such a place, the lawn mower could turn over or fall Before making access to moving parts, stop the engine, and keep your hands, feet, clothing, accessories and etc. away so as not to be caught in the moving parts of the lawn mower Be alert when you approach blind corners and objects that may obscure your vision. Watch for holes, ruts, or bumps. Tall grass can hide obstacles. 8

10 FOR SAFE OPERATION Never rest a foot on the brake pedal. If so, the brakes wear rapidly, which may lead to serious accidents Never attempt to do the mowing operation without the discharge cover in place or with the cover left open Never attempt to operate without the drive shaft cover in place Do not attempt to adjust the cutting height while the engine is running Adjust the cutting height with the gauge wheels in accordance with the condition of the ground surface at the working site. Mowing on rough ground with low cutting height may cause the blades to hit soil or stones, which is very dangerous If you strike an object or if the lawn mower vibrates abnormally, stop the lawn mower immediately, wait for all moving parts to stop, and inspect the cutting unit(s). Make all repairs before you resume operation Be sure to keep the grass discharging part clean. A clogged discharging part may cause the discharge cover to open, resulting in scattering of grass and stones, which is very dangerous Never allow grass or leaves to accumulate around heated parts such as the engine and the muffler, or this may cause a fire Before moving the lawn mower to another place, be sure to stop the mower blades and lift up the mower deck. Otherwise, they may hit stones and scatter them around, which is very dangerous When driving over a levee or a step, stop the mower blades, lift up the mower deck, and move the lawn mower straight to the levee and make it climb over slowly. Avoid climbing over a levee too high, or the lawn mower may fall sideways or turn over Stop the cutting unit(s) when you are crossing gravel areas Watch for traffic when you are operating the lawn mower near a roadway or when crossing a roadway. 9

11 SMM Never attempt to use the lawn mower to draw an implement or a trailer. It is not designed to draw a load Stay alert and stop the lawn mower if people or animals enter the area Do not carry passengers Never carry children, even when the mower blades are not rotating. Children may fall off the lawn mower and become seriously injured or prevent you from operating the lawn mower safely. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the lawn mower Before stopping the engine, be sure to lower the mower deck onto the ground, apply the parking brake or parking lock, and move the PTO lever to the OFF position Before leaving the operating position of the lawn mower for any reason, always do the following: - Stop the lawn mower on level ground. - Stop the cutting unit(s), disengage PTO, and lower the attachment(s). - Disengage the drive(s). - Apply the parking brake or parking lock. - Stop the engine and wait for all moving parts to stop. FIG. 6 10

12 FOR SAFE OPERATION 4. OPERATION ON A SLOPE DANGER: Slopes are a major factor related to accidents with lawn mowers, resulting in severe injuries. We cannot recommend the lawn mower with mower deck be operated on a slope. All slopes require extra caution; no slope is safe. You can lose control of the lawn mower on a slope because of one of the following: - the wheels lack traction; you are driving the lawn mower too fast. - you are not braking properly; the lawn mower type is not suited for the task. - you are unaware of the ground conditions (especially slopes). - you incorrectly hitch an attachment or distribute a load. FIG. 7 If the lawn mower has to be used on a slope, never use it on a slope of more than 12. Even if using it on a slope of less than 12, be sure to abide by the following instructions. A slope angle of 12 specified with the lawn mowers equipped with the attachments mentioned respectively. - The lawn mower is not equipped with any attachments or a cabin than a standard mower deck and collector. - The lawn mower is equipped with a standard mower deck and collector. Grass catchers and other attachments can change the stability of the lawn mower. Follow the instructions for adding weight to improve the stability of the lawn mower. When your lawn mower is equipped with an implement other than a standard mower deck and collector, never fail to ask your dealer about machine balance. Always follow their advice. Bumper SET Weight (15) SET Parts code of weight Quantity (Max) Note To equip weight, bumper set is required Be sure to wear a helmet during operation If you feel uneasy operating your lawn mower on a slope, do not mow it Evaluate the terrain to determine what accessories and attachments you will need to be safe Do not mow near drop-offs, ditches, or embankments. You can tip the lawn mower over if a wheel is over the edge of a drop-off or if an edge caves in. Uneven terrain can cause the lawn mower to overturn. 11

13 SMM Never perform mowing operation on wet grass Avoid sudden starting and stopping Mow up and down a slope; do not mow across it Mow a slope by moving slowly. Do not suddenly change your speed or direction Do not turn on a slope unless it is necessary, and then, turn slowly downhill, if possible If the tires lose traction, disengage the cutting unit(s) and proceed slowly, straight down the slope. Do not apply the brake on the lawn mower that is sliding down a slope. Always keep the lawn mower in gear, especially when travelling downhill Do not use the grass catcher(s) while you are mowing a steep slope Do not try to stabilize the lawn mower by putting your foot on the ground Avoid stopping the lawn mower on a slope. 5. DRIVING ON PUBLIC ROADS 5.1. This lawn mower cannot be driven on a public road without authorization by a local government agency. etc. Therefore it may be illegal for the lawn mower not only to travel on but also to cross a public road When transporting the lawn mower on a public road, load it on a truck. 12

14 FOR SAFE OPERATION 6. LOADING ONTO OR UNLOADING FROM A TRUCK 6.1. When loading the lawn mower onto a truck, turn off the truck s engine, apply the parking brake to the truck, and chock the wheels to avoid unexpected moving of the truck Pay sufficient attention to safety conditions around the lawn mower and have it guided by someone to assist the operator. Never allow other persons to approach the lawn mower, especially in front of or behind it When loading the lawn mower onto a truck, lift up the mower deck fully and reverse it straight back at sufficiently low speeds. Drive it forward when unloading it from the truck. FIG If the engine stalls unexpectedly on the ramps, depress the brake pedals immediately and roll the lawn mower to the ground by releasing the brake gradually. Then start the engine and try again Use ramps with the same or better specifications mentioned below. When the lawn mower is equipped with the attachments other than those included in the specifications mentioned below, ask your dealer for advice. Specifications of the ramps for the SXG 323 and SXG 326 Length...more than 4 times the height of the platform of the truck Width(effective width)... more than 30 cm Required quantity... 2 ramps Capacity (one ramp)... more than 750 kg Ramps should have anti-skid surfaces. The above specifications are effective with the lawn mower with the following configurations. - The lawn mower is not equipped with any attachments or a cabin than a standard mower deck and collector. - The lawn mower is equipped with a standard mower deck and collector. FIG. 9 13

15 SMM54 7. MOUNTING AND DISMOUNTING OF THE MOW- ER DRIVE SHAFT The mower gear box is driven through a drive shaft with universal joints from the lawn mower. When connecting or disconnecting the shaft, follow the next instructions Lower the mower deck onto the ground, stop the engine, remove key from the starter switch, and apply the parking brake or parking lock before mounting or dismounting the drive shaft Move the PTO lever to the OFF position ( ) Make sure that the PTO shaft and mower blades stop completely The drive shaft should be mounted or dismounted at the lawn mower side. Never leave the shaft connected only at the lawn mower side. If the PTO shaft be driven unexpectedly, the shaft will be swung around and damage the lawn mower or cause serious accidents. 8. LAWN MOWER MAINTENANCE 8.1. Never start the engine in a closed place. Exhaust fumes contain poisonous carbon monoxide, so sufficient ventilation should be provided when starting the engine indoors Be sure to wear safety glasses and gloves when servicing the lawn mower When servicing the lawn mower or mounting or dismounting the mower deck, place the lawn mower on level, hard ground Service the lawn mower in a place sufficiently illuminated, or darkness may cause unexpected accidents Do not adjust or repair the lawn mower while the engine is running When servicing the lawn mower or mounting or dismounting the mower deck, stop the engine and remove the key (if applicable) to prevent someone from accidentally starting the engine and apply the parking brake or parking lock. 14

16 FOR SAFE OPERATION 8.7. The engine, muffler, radiator, etc. are very hot just after operation, so wait until those heated parts cool down sufficiently to avoid burns Never remove the radiator cap while the engine is hot or running. Wait until the engine cools down and then relieve the radiator pressure by releasing the radiator cap. Carelessly pouring cooling water into the heated radiator can cause serious damage to the radiator and the engine. Careless removal of the radiator cap can cause serious injury because of superheated water vapour Before servicing the lawn mower, be sure to move the PTO lever to the OFF position ( ) and make sure that the mower blades have stopped completely. Rotating blades may cause serious accidents. FIG While adjusting the lawn mower, keep your fingers away from all pinch points When servicing the lawn mower, use proper tools. Using makeshift tools may lead to injuries or poor service, which may result in unexpected accidents during operation When removing a tire, chock other tires and support the lawn mower securely. When installing tires, be sure to tighten the wheel nuts to the specified torque. Loose nuts may cause serious accidents The mower blades are sharp and can cut you. Wrap the mower blades or wear leather gloves when you service them. On the lawn mower with two or more mower blades, rotating one mower blades may cause the other mower blades to rotate Never step on the mower deck, or the mower deck may be damaged or deformed, which may lead to breakdown or accidents A first aid kit and a fire extinguisher should be kept in a place always in instant access On the lawn mowers with hydraulic devices, hydraulic fluid escaping under pressure can penetrate and seriously damage the skin, requiring immediate medical assistance. Do not use your hand to check for a hydraulic leak; use a piece of cardboard. Be sure to consult your dealer about the hydraulic and fuel injection system troubles. 15

17 SMM If any hydraulic fluid is injected accidentally into the skin, it must be removed within a few hours by a doctor familiar with this type of injury Never allow grass or leaves to accumulate around heated parts, such as muffler, engine and brake, and around terminals of battery, which have possibility of leakage of electricity by water. Otherwise, it may cause a fire Replace any worn or damaged parts with the manufacturer s recommended parts To reduce the fire hazard, keep the engine, muffler (silencer), battery area, and fuel storage area free of debris If fuel has to be drained, this should be done outdoors Check the brake(s) on the lawn mower frequently and adjust and service the brake(s) as required Replace faulty mufflers (silencers) Do not change the engine governor settings or overspeed the engine. Operating an engine at an excessive speed can increase the risk of personal injury The grass catcher components are subject to wear and damage, exposing you to moving parts or thrown objects. Frequently check and replace them with the manufacturer s recommended parts when necessary Be sure to reinstall the removed parts in place. Never attempt to start the engine with any parts removed Never attempt unauthorized modification of the lawn mower as this could be very hazardous. Damaged or worn parts should be replaced with ISEKI genuine spare parts. Unauthorized parts may cause breakdown of the lawn mower, accidents, and ISEKI warranty to expire Make sure all fixing bolts or nuts are securely tightened especially those that hold the mower blades.

25 SMM54 g. Move the PTO lever to the ON ( ) position. IMPORTANT: When engaging the PTO clutch, slow down the engine speed sufficiently for safety. CAUTION: Whenever you encounter with any trouble of the mower, ask your dealer for repair immediately. WARNING: As soon as the PTO lever is set to the ON ( ) position, the mower blades start rotating and eject cut grass or stones through the discharge opening. Consequently, before operating the PTO lever make sure that there is no people, animals, or properties like buildings, cars, etc. within a range where ejected grass or stones may reach. The mower blades should be turned only on turf or grassland and with the mower deck lowered. h. Set the throttle lever to the high speed ( ) position to raise engine speed. i. As the HST forward travel pedal is depressed gradually, the lawn mower starts to travel. CAUTION: Be sure to start mowing at sufficiently low speeds and increase travelling speed gradually. IMPORTANT: The screens of the air-intake openings provided under the steering wheel, the upper net provided underside the engine hood and the radiator screen should be kept clean. Never keep on operating with clogged screens, or the engine may be overheated, which may result in engine seizure. EMERGENCY STOP When any of the following abnormalities is encountered, stop the lawn mower and mower deck immediately. - Abnormal noise - Abnormal vibration - Abnormal smell - Blade hitting an obstacle - The lawn mower hitting an obstacle The cause of trouble should be found and corrected immediately. If it is not solved by yourself, consult your dealer. Never attempt to keep on operating the lawn mower without finding and correcting the cause of trouble. After striking a foreign object, inspect the mower for damage and make repairs before restarting and operating mower. When the operator leaves the seat, the safety system automatically stops the engine. When leaving the lawn mower to remove obstacles such as twigs, pebbles, etc., the PTO lever must be moved to the OFF position ( ) and the parking brake (UGE TYPE / GE TYPE) or parking lock (UE TYPE / E TYPE) must be applied. STOPPING MOWING OPERATION a. Release the HST travel pedal. b. Set the throttle lever to the low speed position ( ) to reduce engine speeds. 1 (SXG22) (SXG326) FIG. 18 (1) Throttle lever c.

(UE TYPE / E TYPE) CAUTION: Park the lawn mower on level, hard ground and make sure that the parking brake (UGE TYPE / GE TYPE) or the parking lock (UE TYPE / E TYPE) are applied securely. 24

26 MOWER OPERATION d. Move the PTO lever to the STOP ( ) position. e. Turn the starter switch to the OFF position to stop the engine. IMPORTANT: Never attempt to stop the engine abruptly when it is running at high speeds. Be sure to let the engine idle for about 5 minutes after long operation to cool down engine sufficiently and then stop the engine. Abrupt engine stopping may lead to overheating causing seizure. f. Remove key from the starter switch without fail. CAUTION: When you leave the lawn mower, be sure to stop the engine and remove key from the starter switch to prevent the lawn mower from being started unexpectedly by children or unauthorized people. EFFICIENT MOWING IMPORTANT: Be sure to mow at full throttle ( ). Choose an adequate travelling speed in accordance with the height or other conditions of grass to be cut. When the screens for the air-intake openings and radiator are clogged with dust, clean them at once. Never go on operating with clogged screens. Mowing is desirable when the grass is dew-free: in the afternoon or late afternoon, thus preventing the mower from heavy clogging. Always keep the mower deck clean. Check the blade ends for damage. Repeated mowing is recommended before the grass grows to high. Cutting grass too closely may damage the grass. Too maintain a green lawn, never mow more than one-third off the height of the grass in one mowing. A slower travelling speed will result in improved mowing. Avoid selecting such a travelling speed that causes the lawn mower to bounce. Short or fast turns will damage turf. Slow down sufficiently when turning. Frequent sharpening of the mower blades results in beautiful finish and less load on equipment, which leads to economical operation. a. For mowing tall grass i. Mow grass twice. First, mow the grass to a height low enough for the next finishing pass. Then finish to the desired grass height. The second travelling pass should be shifted sideways by 20 cm (8 in.) or so, or travel perpendicular to the first passes, which will result in a beautiful even finish. ii. When trying to finish in one pass, select a sufficiently slow travelling speed. It may also be required to set the cutting width to half or one-third of that for normal operation. b. For mowing highly moist grass or mowing on wet ground i. If the turf damage by the tires could result, wait until the grass and land have dried sufficiently. ii. Wet grass requires a higher grass cutting height setting than when mowing dry grass, as the cutting height is often lower than expected during operation. iii. Select a sufficiently slow travelling speed and avoid sudden starts, turns, and stops. If not, the turf may be damaged. c. For mowing low moisture content grass or when there is much dead grass i. Advance should be in a direction where the dust does not hit the operator by taking into consideration the direction of the wind. ii. When the air-intake screens are clogged, clean them at once. IMPORTANT: When operating the lawn mower in dusty circumstances, keep on paying attention to the coolant temperature warning lamp. Never continue operating when screens are clogged, or engine breakdown may result. 25
