Hazard Information
Stop the equipment. Stop the engine.
Ensure the protective locks or controls are in the applied position.
Disconnect the batteries whenever performing any maintenance or before servicing the electrical system. If the
engine has an electric starter, disconnect and tape the battery ground leads to prevent accidental starting.
Disconnect the batteries before performing any welding. Failure to do so will cause serious damage to the power
unit's operating system.
Do not attempt any repairs or adjustments to the engine or equipment while it is running.
Do not attempt any repairs that you do not understand or for which you are not qualified. Use proper tools; re-
place or repair broken or damaged equipment.
Block or restrain the equipment, if applicable before operating or performing maintenance.
Do not adjust, or set, hydraulic pressures higher or lower than those specified in the parts manual.
Use caution when removing filler caps, grease fittings, pressure taps, breathers or drain plugs. Hold a rag over
the cap or plug to help prevent being sprayed or splashed by liquids under pressure.
Wear a hard hat, protective glasses, hearing protection and other protective equipment as required by job con-
ditions.
Do not wear loose clothing or jewelry that can catch on controls or other parts of the equipment.
Make certain all protective guards and covers are secured in place.
Use all cleaning solutions with care.
Never put maintenance fluids into glass containers since glass containers can break.
Report all needed repairs.
Maintenance Procedures
Pressurized Air and Water Hazards
Pressurized air can cause personal injury. When using pressurized air for cleaning, wear a protective face shield,
protective clothing and protective shoes.
The maximum air pressure must be below 30 psi (205 kPa) and maximum water pressure must be below 40 psi
(275 kPa) for cleaning purposes.
Wear eye protection at all times when cleaning the cooling system. Pressurized water could cause debris and/or
hot water to be blown and result in serious personal injury.
Do not spray pressurized water at the control box. Pressurized water could result in damage to the onboard
computer module, which could cause the operating system to malfunction.
Fluid Penetration Risk
Always use a board or cardboard when checking for a leak. Escaping fluid under pressure, even a pinhole size
leak, can penetrate body tissue, causing serious injury or possible death.
If fluid is injected into your skin, a doctor familiar with this type of injury must treat it immediately.
