Komatsu — GENERAL WORK PRECAUTIONS

SAFETY PRECAUTIONS This machine is assembled using high strength fasteners. Replacement fasteners must be of the same size and strength as the originals. DO NOT SUBSTITUTE. Refer to the Parts Book for this machine. Tighten fasteners to the proper torque. Refer to Section 4. New product graphics are available from your Distributor. For the proper position of the product graphic, refer to “SAFETY PRODUCT GRAPHICS AND LOCATIONS”. NEVER adjust relief valves higher than the specified pressure because this may damage the machine and lead to an injury. When checking pressures, use the correct gauge for the expected pressure. Consult your Distributor for information and service.

Replace any missing or defaced product graphics. When parts which have product graphics on them are replaced, be sure to install new product graphics. GENERAL WORK PRECAUTIONS Keep work area clean and dry. Remove water and oil spills immediately to reduce the chance of slipping and injury. When welding, wear proper protective equipment, such as a helmet, dark safety glasses, protective clothing, gloves and safety shoes. DO NOT LOOK AT THE ARC WITHOUT PROPER EYE PROTECTION. Do not pile up oily or greasy rags; they are a fire hazard. Store them in an approved, closed metal container. If necessary to do welding on the machine, attach the ground cable close to the weld area.

Do not attach the ground cable where the current can flow through bearings or mounting pads because this will damage the parts. Use a non-toxic, non-flammable commercial solvent for cleaning parts, unless otherwise specified. Avoid use of gasoline, diesel fuel, kerosene or other flammable solvents for cleaning parts. NEVER place these solvents in an open drain. Use extra caution when jacking up the machine. Jacking up the machine can be hazardous if performed improperly. Use jacking equipment of sufficient capacity. Be sure the jacking points are strong enough to support the machine. Be sure the jack is stable and well supported.

Before jacking up the machine, block the tires which will not be lifted. Lock the front and rear frames together with the locking bar and pins. If the rear tires are being lifted, block the rear axle to prevent it from pivoting unexpectedly. DO NOT run the engine with the machine on jacks. For your safety, transfer the weight of the machine to approved blocks, before servicing the machine. Corrosion inhibitors are volatile and flammable. Use them only in a well ventilated area. Keep flames and sparks away. Do not smoke. Store container in a cool, well ventilated place. Avoid prolonged exposure to volatile corrosion inhibitors because eye and skin irritation may occur.

Excessive or repeated skin contact with sealants or solvents may cause skin irritation. In case of skin contact, remove sealant or solvent promptly by wash- ing with soap and water. Follow the manufacturer’s advice whenever cleaning agents or other chemicals are used. Use the proper tool for the job. Be sure all tools are in good condition. Do not use tools which are worn, bent or have mushroomed heads because they can lead to injury. Wear eye protection when using air or water under pressure to clean parts. Limit air pressure to 2.1 kg/cm* (30 psi / 200 kPa) and water pressure to 2.8 kg/cm* (40 psi / 275 kPa). Never align holes with fingers or hands.

Use the proper aligning tool to avoid injury. Remove sharp edges and burrs from reworked parts. When cutting, grinding, pounding, prying or whenever material could fly or fall, wear proper protective equipment such as goggles, hard hat, safety shoes and heavy gloves. Many of the machine’s parts are hardened and can chip. Do not carry loose objects in pockets because they might catch on the machine and result in a fall or injury. Use only properly grounded auxiliary power sources for chargers, heaters, electrical drills and similar equipment to reduce the chance of electrical shock. Wear hand and eye protection when draining hot fluids. 1-8
