Before performing maintenance on the machine, unless otherwise specified, lower all equipment. Engage the hydraulic and anti-travel lock. Stop the engine.
Read the warning and service information provided on the machine. Follow servicing instructions carefully.
Do not start or operate the machine while it is being serviced. Attach a warning tag to the controls.
There are certain hazards which must be recognized as potential causes of personal injury. Be aware of these hazards and follow the recommendations which are listed below.
Avoid Crushing or Cutting Injurys
Never attempt adjustments while the machine is moving, or the engine is running.
Any implement can fall if a control is moved, or a line breaks.
Support equipment when working beneath it. Do not depend on hydraulic cylinders to hold it up.
The fan blades will throw or cut any object that falls, or is pushed, into them.
Drive shaft and universal joints, when rotating, can catch loose clothing, wipe cloths, or hair.
Wear gloves when handling cable. Do not use kinked or frayed cable; it is weakened.
Wear protective glasses when hammering on metal, drifts, punches, or chisels. Chips can fly from the object or hammer.
The radiator and all lines to heaters, and the engine contain hot water or steam. To avoid burns, remove the radiator cap slowly. Allow the cooling system components to cool before draining the coolant.
Lubricants will be hot enough to cause serious burns after machine compartments are up to normal temperature. Allow the compartments to cool before draining.
At operating temperature the hydraulic system is pressurized by hot air in the top of the tank. Remove the hydraulic tank cap slowly to relieve tank pressure. Allow the tank to cool before draining.
Cooling system conditioners contain alkali. Do not drink them or get them in your eyes.
Battery electrolyte is an acid and will harm skin and eyes.
Keep all lubricants and fluids stored in properly marked containers and away from children.
Never put maintenance fluids in glass bottles or glasses that are within the reach of children.
Avoid Fire or Explosion
Diesel fuel and all lubricants are flammable. Do not weld or flame cut pipes or tubes that contain oil. Clean them thoroughly with nonflammable solvent before welding or flame cutting.
Do not smoke when refueling.
To avoid fires, clean up oil spills and trash buildup. Steam clean the machine.
The vapor (hydrogen gas) from a charging battery is explosive. Do not smoke when checking batteries, or working around them.
Tighten loose hose clamps or fasteners. Replace missing ones.
Tighten loose fluid fittings or connections.
Check for misalignment of tubes, hoses, or items containing fluid. Reroute lines if necessary to prevent interference.
Repair or replace loose, frayed, damaged, or disconnected wires.
Replace or tighten missing or loose mufflers or exhaust system parts.
Shields, which protect hot exhaust system components from oil or fuel spray, must be installed correctly.
To prevent vibration, rubbing against other parts, or excessive heat buildup during operation, make sure all clamps guards and heat shields are installed correctly.
Safety Equipment and Practices
Wear a hard hat, protective shoes, and protective glasses when doing lubrication and maintenance work.
Limit air pressure to 30 psi (205 kPa) when cleaning with air.
Never point an air nozzle at anyone.
Do not use frayed or kinked cables. Know the weight limits of cables, chains, and slings before using them.
Use caution when removing caps, drain plugs, fittings, or pressure taps.
Use a "DO NOT OPERATE" or similar WARNING tag, on the vehicle starter switch or controls, when working on a machine.
Use steps and grab irons when servicing the machine.
Store rags that have oil or other flammable material on them in a safety-type container. Keep the container away from open fires, welding, or flame cutting areas.
Operate the engine only in a well ventilated area. In a closed area, vent exhaust fumes to the outside.
Before servicing the electrical system, turn the disconnect switch off and remove the key.
Block the bucket when changing teeth.
Use the steps, grab irons and walkways when mounting or moving around on the machine.
