SAFETY CONDITIONS 4.1. General rules Front axis of the tractor should be well weighted to keep its balance and allow for its steering. If need be, use front wheel weights. Any operation with the hydraulic lift lever should be conducted from the operator's seat; DO NOT move the lever from outside of the tractor. When switching from working to transport position the whole or at least one end (from tractor PTO side) of PTO shaft should be dismounted. Operating without safety guards is not permitted. Neither operation with damaged or raised guard is permitted (danger of stones, etc. being thrown out). Start mowing only when the tractor PTO reaches its nominal 540 rpm value. DO NOT exceed 600 PTO rpm. No unauthorized personnel is allowed to remain within the danger area of at least 50 m. Keep particular caution when operating near roads and in stoney areas

8 Any maintenance and adjustment work is allowed only with the drive disconnected and the knife drums in complete standstill. Any service and repair operations must be conducted with the tractor drive disconnected, slides touching the ground and all rotating parts in the complete standstill. Be certain that children and animals are at a safe distance away from the machine. Never allow anyone to ride on a machine or tractor. Fields, where mowing with rotational mower is performed should firstly be cleaned out of any hard elements. Bigger stones should be removed, and smaller rolled in spring period. Knife mounting condition should be checked regularly (for riveting and wearing of shaping bolts, as well as for deformation and wearing of holders). Damaged or worn knife holders must be replaced. When the mower is lifted for repair on the 3-point linkage, it should be secured against falling by a mechanical support or by chain. The bolts and other fasteners should be checked regularly. Operating with damaged or worn fasteners is not permitted. Switching from transport to working position (and the other way round) should be performed only when slides touch the ground. During operation of the mower the Regulation of the Farm Ministry and Food Economy (Rozporządzenie Ministra Rolnictwa i Gospodarki Żywnościowej) from dealing with safety and hygiene during the operation of tractors, machinery, tools and equipment used for farming (Dz. U. nr 12/98 poz. 51), should be observed. The tractor used with the mower should be equipped with a driver's cabin. The mower cannot be used if the tractor has not been properly balanced. Never start the mower if it is in the up position. Never start the mower if people or animals are in the proximity of the mower. Never lift the tarpaulin apron before the rotating parts of the mower come to a complete stop. Caution: Cutting knives keep rotating for several seconds after the engine is stopped. Observe all safety signs, warnings or warning signs placed on the mower. Before turning on the tractor make sure that all drives are disengaged and the hydraulic control lever is in neutral.

PTO shaft is installed onto mower s PTO splined extension and tractor s rpm, paying attention, so that external pipe of shaft s guide is at tractor s side. Protect guide against rotating by mounting adjustment chain on constant point of tractor s body and mower s bar. At clamp shafts it is required to install roof guides on both tractor and mower. If need be, shorten the PTO shaft according to its operator s manual given by the shaft s manufacturer (Fig. 16)

20 Fig. 16. Instruction of PTO shaft shortening Use only with PTO shafts as recommended by the manufacturer. Before starting work check if all the covers (tractor, machinery and shaft) are in place and functioning. Damage or lost elements must be replaced with original spares. Check whether the articulated telescoping shaft is properly installed. Never get close to rotating part sit could result in injury or death. During servicing of the shaft or the machine the engine and the power takeoff the tractor must be turned off. Before operating any machinery carefully read the operating manuals of the shaft and the machine. The PTO shaft should remain mounted only for the mower operation time. For transport and service time the shaft should be disconnected from the tractor rpm Dismounting machine from tractor When dismounting, make sure there is no person in between the mower and the tractor. To dismount the mower from the tractor: turn cutterbar's drive off, place the mower on an even, paved ground, then lower and inspect, if the mower is properly secured against falling, turn the tractor's engine off and take ignition key off, dismount the PTO shaft and place it on a PTO shaft holder, that is standard-delivered with the mower, detach tractor's upper link and lower strands from mower's linkage

21 6. MOUNTING AND ADJUSTMENTS 6.1. Timing of knives Manner of mounting knives and their timing in mowers is provided in Fig. 17 and Fig. 18 respectively. Fig. 17. Timing of knives on mower s drums and their mutual placement in relation to each other on neighbouring drums 6.2. Knife replacement Use knives recommended by the manufacturer only. The cutting edges of the new knives should be directed towards ground. When replacing the knives use a special lever to tilt the knife holder (Fig. 18). New knives should be mounted with their edges up. In the case of used knives, if one cutting edge is worn, remove the knives onto the other drum. Fig. 18. Manner of knife mounting on drums: 1 mounting lever; 2 - knife holder; 3 knife

22 When replacing knives the tractor's engine should be stopped and ignition key taken out. The PTO shaft between the mower and the tractor must be disconnected Adjusting cutting height The preset mowing height is 50 mm. Mowing height (Rys. 13) of 42 mm can be obtained by dismounting distance rings. By putting extra rings under the retain plate, mowing height of 58 mm is obtained. Extra rings should be ordered separately. a) Retain plate 42 mm b) Sliding saucer Distance ring Mounting screws 50 mm Distance ring Retain plate Sliding saucer Fig. 19. Adjusting the cutting height by: a) removing, b) fitting the distance ring 6.4. Operational and technical maintenance Knives and knife holders control All knives should be of the same length and weight. Replace them, if necessary, only in sets of the same length and weight. Knife holders cannot be deformed and the holder pin, on which the knife is mounted may be worn max. 50% of the section (Fig. 20). Excess pin wear as well as the holder side deformation or wear result in its replacement. Wearing condition and pin riveting should also be checked. In the event of loosening the rivet fastening the knife holder should be replaced. Fig. 20. Permissible wear of knife holders

23 Condition of knives and holders should be checked each time before commencing any operation. Damaged or worn elements pose danger of throwing and are as well health and life threatening. Operating with too damaged or worn holder is not permitted. It may cause knife outing, while bearing in mind its high speed, can be dangerous. Potentially such knife may cause tractor s tire to be punctured Belt gear s V-belts tension control Deflection of belts should not be greater than 30 mm when pressed with finger. Belts are tensed with spring tensioner (Fig. 15) featuring control bar (1) of spring tension. Clearance between end of the bar and middle beam surface (dimension A) should be mm. If clearance is bigger (more loose belts), it should be adjusted to required value. In the event of damaging one of belts, the entire set must be replaced. Z 064/3 Z 064 A a) A b) Fig. 21. Spring tensioner of v-belts. Control dimension A should be between 0 and 3.0 mm. 1 v-belt tensioner index Removing clogging and jams When operating the mower pay attention to variable conditions on field, which may influence the mower clogging and jams, such as: terrain unevenness, height and density of grass as well as other objects in the grass (stones, branches, piles of soil). In order to avoid clogging and jams, operating speed should be adjusted to the mentioned conditions. Removing clogs and jams while the machine is in operation can lead to the accident! In case of machine blockage caused by wrapped material, set the machine on a flat surface, remove excess material using sharp tool. After clearing the machine check if nothing has been damaged. To remove any clogging it is obligatory to disconnect the drive and the motor, take out the ignition key. When eliminating any clogging on the machine, use also safety means for operator, so protective gloves and tight wear

24 Daily maintenance It is recommended for the operator to wear protective gloves when performing maintenance works. Upon daily completion of operation the following should be performed: remove grass and mud from the mower, wash mower with water under pressure upon each mowing, especially inside the drum (holders. Knives) and sliding saucer, as dried mud with grass may cause premature wear of bearings in sliding saucer hub and vertical shaft, inspect all visible external parts and assemblies with their connection; all loosen screws shall be tighten and worn or damaged parts replaced, grease the PTO shaft tubes with STP grease, if necessary, lubricate the other parts and assemblies in accordance with the lubrication instructions (item 7) After-season maintenance and storing of machine At the end of the season the mower should be cleaned, washed and dried. Carefully grease unpainted surfaces and 3-point linkage pins. After that the following work should be carried out: Remove any traces of rust and paint the area affected, Loosen v-belts Check lubrication of gear box (3-point linkage frame) and gears Fig. 22. In the event of finding leaks and damages of polypropylene cover of vent valve (Table 1. Item 15) leaks should be removed by dismounting cover and possible replacement of self-adhesive sealing as well as replacement of valve cover. If water is found in the oil, it must be replaced, otherwise the gears, bearings and shafts could be exposed to corrosion what in result could lead to subsequent failures. When mounting the cover, pay attention to careful laying of the sealing and adequate screw torque Restarting the machine after repairs or longer storing periods Make sure that all nuts and screws are tightened with correct torque (Tab. 4). Make sure that all guards are installed in place. As the storing period is over lubricate the whole machine. Tab. 4. Values of bolt tightness

25 7. LUBRICATION RECOMMENDATIONS 7.1. Gear trough (gearbox) Oil level should be checked regularly through the vent valve of gearbox. It should be 15 30mm from the frame bottom. Amount of oil in gearboxes of mowers Z 064 and Z 064/3 is 2 litres. In case of lower oil level check whether there is no leak and remove the possible cause, and then refill the oil to the adequate level. Fig. 22. Lubrication scheme for mower Tab. 5. Amount of oil in gear trough Markings Amount of oil [l] Lubricant type Frequency of lubrication or replacement 2,0 Transol oil Once every 3 seasons (with intensive operation) 7.2. Risks present when lubricating If risk of splashing is present, make sure to wear protective eyewear with side guards. When lubricating protect eyes and skin against contact with the substance. Therefore use adequate protective wear with long sleeves and protective footwear. Also use protective gloves. In case of a contact with skin, immediately wash the infected area with plenty of water with soap. Do not allow the product to contaminate water outlets, water courses and soils. In case of an unintentional release to the environment plug the leak, limit the spillage, and then collect the oil with non-flammable absorbent material (e.g. sand). The product is flammable. In case of fire, use adequate fire-extinguishing means (e.g. foam, water mist, extinguishing powders). Do not use water jets.
