SECTION 2 SAFETY PRECAUTIONS Page 8 2.4. MAINTENANCE Never align holes with fingers or hands. Use a proper aligning tool. Be sure all tools are in good condition. Do not use tools which are worn, bent or have mushroomed heads. Use the proper tool for the job. Remove sharp edges and burrs from reworked parts. For field service, move machine to level ground if possible and blocks the tracks. If work is absolutely necessary on an incline, block the machine and its attachments securely. Move the machine to level ground as soon as possible. Before working on the machine, turn OFF the electrical system master switch and take it out so no one will start it unexpectedly.
Do not carry loose objects in pockets that might catch on the machine or fall unnoticed into open compartments. Before working on any part of the engine or electrical system, disconnect the battery ground cable. Tag the cable and all controls to alert personnel that work is in progress. When it is necessary to make any checks or adjustments with the engine operating, always use two people. One trained person must be in the operator's seat to safeguard the second person making the checks or adjustment. As an added precaution, when making checks or adjustments with the engine operating, make sure the transmission shift lever is locked in neutral (N), and the parking brake is locked.
Never stand on the tracks or near the blade while the engine is operating. If the engine is running and the side doors are open or removed be careful of rotating parts such as the fan and belts that can cause serious injury. Never operate the engine when cleaning or lubricating the machine. Serious injury could result from contacting moving parts. Use a non-toxic, nonflammable commercial solvent for cleaning parts, unless otherwise specified. Never use gasoline, diesel fuel, kerosene or other flammable solvents for cleaning part. Excessive or repeated skin contact with sealant or solvents may cause skin irritation.
In case of skin contact, remove sealant or solvent promptly by washing with soap and water. Follow the manufacturer’s advice whenever cleaning agents or other chemicals are used. Lower blade before making hydraulic adjustments. To prevent personal injury, be sure to personnel are standing in the way of the blade when it is being lowered. Never allow anyone to walk under or be near unblocked raised equipment. Provide proper ventilation when operating in a closed building to avoid danger of exhaust gases. Exhaust gases are dangerous and can cause unconsciousness and death.
Hydraulic fluid escaping under pressure from a very small hole can be almost invisible, yet have sufficient force to penetrate the skin. Use a piece of cardboard or wood to search for suspected leaks. Do not use hands. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can occur if proper medical treatment is not administered immediately. When welding, wear proper protective equipment such as a helmet, dark safety glasses, protective clothing, gloves and safety shoes. Wear dark safety glasses near welding. DO NOT LOOK AT THE ARC WITHOUT PROPER EYE PROTECTION. TD-20H DRESSTA
