Always Use Adequate Equipment Supports and Blocking Do not allow weight or equipment loads to remain suspended. Lower everything to the ground before leaving the operator’s seat. Do not use hollow, cracked or unsteady, wobbling weight supports. Do not work under any equipment supported solely by a lift jack. Obtain immediate medical attention if pressur- ized oil pierces the skin. WARNING!!! Failure to obtain prompt medical assistance could result in gangrene or other serious damage to tissue. Do Not Work on Hot Engines or Hot Cooling or Hydraulic Systems Wait for the engine to cool off after normal opera- tion.
Park the wheel loader on a firm, level surface and lower all equipment before shutting down and switching off controls. When engine lube oil, gearbox lubricant or other fluids require change, wait for fluid temperatures to decrease to a moderate level before removing drain plugs. Use Correct Replacement Fasteners Tightened to Proper Torque Refer to the General Maintenance section of the Shop Manual for information on tightening torques and recommended assembly compounds and always use the correct part. NOTE Poor or incorrect fastener connections can danger- ously weaken assemblies. Oil will drain more quickly and completely if it is warm.
Do not drain fluids at temperatures exceeding 95°C (203°F), however do not allow full cool-down. Dispose of All Petroleum-based Oils and Fluids Properly Physical contact with used motor oil may pose a health risk. Wipe oil from your hands promptly and wash off any remaining residue. Cool-down is Required Prior to Radiator or Reservoir Checks Stop the engine and allow heat to dissipate before performing service on the engine radiator or hydraulic fluid reservoir. Both assemblies have air vent levers at or near the filler cap for venting built- up air pressure. Release the levers before trying to take off filler caps and LOOSEN CAPS SLOWLY, prior to removal.
Used motor oil is an environmental contaminant and may only be disposed of at approved collection facilities. Never drain any petroleum-based product on the ground or dispose of old oil in municipal waste collection containers, or in metropolitan sewer systems or rural landfills. Check state and local regulations for other require- ments. Pressurized Hydraulic Oil Fluid Leaks Can Be Dangerous Fluid leaks from hydraulic hoses or pressurized components can be difficult to see but pressurized oil has enough force to pierce the skin and cause serious injury. Check Tire Pressure and Condition Maintain tire pressure but do not over inflate. Inspect tires and wheels daily.
When inflating tires, follow procedures in the Maintenance section, which include using an extension to allow you to avoid standing in front of or over a tire. Do not change a tire unless you have both experience and proper equipment. Always use a piece of wood or cardboard to check for suspected hydraulic leaks. Never use your hands or expose your fingers. 1-12 SAFETY Mega 300-III Shop Manual
