2 At Sandvik we put safety first Sandvik Construction is committed to ensure safety and increase productivity for our customers by providing the support needed through safe products and product information. Grinding of bits Drill bits have cemented carbide buttons. Cemented carbide is made up of tungsten carbide and cobalt. Grinding buttons will produce dusts or fumes with dangerous ingredients that can be inhaled, swallowed or come in contact with the skin or eyes. Do not breathe dust and in case of inadequate ventilation wear respiratory protection. Wear protective gloves, protective clothing, and eye protection. In particular, avoid dry grinding. lifting procedures Use safe and correct lifting practices while working with heavy items. Consider body position, awkwardness of the item and its weight. Are two people required for the lift, is a lifting device necessary? Assembly of bits Do not touch any equipment whilst it is rotating. The pipe rotation must be stopped before installing or removing a drill bit. Follow site instructions for isolation of rotation motors. Beware of pinch points between the bit, hammer and pipe. hammers and pipes Ensure products have cooled down before disassembling. Never work on hot parts. Consider appropriate hand protection (gloves) for handling warm parts. DEALING WITH WORN PARTS Worn parts should be removed and disposed of appropriately. Consider recycling the used drill bits. Please contact your local Sandvik Construction representative for support and further information regarding the recycling process. Storing All products should be stored in a dry place and in original package until they are required for use. GENERAL The products in this catalog are designed for drilling holes in rock and should only be used for this purpose. Operate the hammer Only operate the controls while the engine is running. Proper personal protective equipment must be worn while you operate the drill rig and while you operate the hammer. Before you move the drill rig with the hammer, ensure that no one will be endangered. Do not go close to the edge of a cliff, an excavation or an overhang. Maintain control of the drill rig while you operate the hammer. Operating the equipment beyond its design limits can cause damage to people or equipment. Know the maximum operating dimensions of your drill rig when the hammer is installed. Ensure that there is adequate clearance between the drill rig and any stationary objects when you are maneuvering the machine. Know the appropriate work site hand signals and the personnel that are authorized to give the hand signals. Hammer maintenance It is important to read the safety procedures in the operator s manual before assembly/disassembly of the hammer. During disassembly, heavy parts may fall out from the hammer. Always keep the hammer in proper position to avoid falling parts. Use a proper assembly stand to avoid fall over or roll over of the hammer or parts of it. Always use tongs with jaws that place a uniform load on the outside diameter of the hammer. Never grip the hammer with pipe wrenches or wrenches that can deform and damage the hammer. Always place tongs on the body of the bit, not on the carbides. Do not apply heat of any type to the piston case to remove the driver sub or the top sub.

3 The all-new RH40 hammer Piston The RH40 hammer has a solid piston and inner cylinder concept. With the porting being done externally, the piston is free of any air channels except for the center bore. The solid piston concept without any cross-holes reduces stress induced failures. This provides for more reliability and long un-interrupted service life. V-lock System The unique V-lock system prevents any movement of the inner cylinder and air distributor. By ensuring no movement, any failures related to galling is greatly minimized. The simple design also ensures ease of assembly and disassembly without the need for any special tools. PISTON BEARING AREA The piston bearing surfaces are designed and located to optimize bearing capabilities and eliminate bending vibrations. Bending vibrations in the piston will cause heavy pressure contact between the internal parts during the striking mode. This will cause galling which would eventually result in failure. Research and development has gone in to designing the bearing surfaces, to ensure that these bending vibrations are eliminated in the RH40 piston. DRILLING IN ALL DIRECTIONS The working principle of RH40 ensures that the hammer starts up in any direction. This makes the new RH40 design exceptionally well suited for all construction applications. 3

19 Information Grinding of Hardmetal Health and Safety Information Material Composition Hardmetal products contain tungsten carbide and cobalt. Routes of exposure Grinding or heating hardmetal blanks or hardmetal products will produce dusts or fumes with dangerous ingredients that can be inhaled, swallowed or come in contact with the skin or eyes. Acute toxicity The dust is toxic by inhalation. Inhalation may cause irritation and inflammation in the airways. Skin contact can cause irritation and rash. Sensitized persons may experience an allergic reaction. Chronic toxicity Repeated inhalation of aerosols containing cobalt may cause obstruction in the airways. Prolonged inhalation of increased concentrations may cause lung fibrosis or lung cancer. Epidemiological studies indicate that workers exposed in the past to high concentrations of tungsten carbide/cobalt carried an increased risk of developing lung cancer. Cobalt and nickel are potent skin sensitizers. Repeated or prolonged contact can cause sensitization. Classification Following hazard classification according to GHS/CLP applies to the hardmetal powder (.% Co<%): Acute Inhalation 3, H33: Toxic if inhaled Carc. Cat., H3: Suspected of causing cancer by inhalation Repr., H3; Suspected of damaging fertility. STOT RE, H3: Causes damage to lungs through prolonged or repeated exposure by inhalation Resp. Sens. B, H334 : May cause allergy or asthma symptoms or breathing difficulties if inhaled Skin Sens., H3: May cause an allergic skin reaction Eye Irrit., H3: Causes serious eye irritation Aquatic Acute, H400: Very toxic to aquatic life Aquatic Chronic, H4: Toxic to aquatic life with long lasting effects Precautionary Statements Do not breathe dust Wear protective gloves/protective clothing/eye protection. Use personal protective equipment as required. In case of inadequate ventilation wear respiratory protection Avoid release to the environment IF INHALED: If breathing is difficult, remove victim to fresh air and keep at rest in a position comfortable for breathing. If experiencing respiratory symptoms: Call a POISON CENTER or doctor/physician If skin irritation or rash occurs: Get medical advice/attention
