GENERAL MAINTENANCE

Poorly maintained equipment can become a safety hazard. In order for the equipment to operate safely and properly
over a long period of time, periodic maintenance and occasional repairs are necessary. NEVER perform routine
service (oil/filter changes, cleaning, etc.) unless all electrical components are shut off. Before servicing the unit always
follow the instructions listed below.
Ensure the Control Power switch is turned to the OFF (O) position.
Ensure the circuit breakers are turned to the OFF (O) position.
Activate (push in) the emergency stop switch.
Disconnect the negative (-) terminal on the battery.
Attach a Do Not Start sign to the control panel. This will notify everyone that the unit is being serviced and
will reduce the chance of someone inadvertently trying to start the unit.
Never wash the unit with a high pressure hose or with any kind of power washer.
Never wash the engine block or fuel tank with a power washer or steam cleaner. Water may enter the cabinet
and collect in the generator windings or other electrical parts, causing damage.
If the unit is stored outside, check for water inside the cabinet and generator before each use. If wet, dry the
unit thoroughly before starting.
Inspect condition of electrical cords. DO NOT use the unit if insulation is cut or worn through.
Check that winch cables are in good condition
and are centered on each pulley. DO NOT use a
cable that is kinked or starting to unravel.
Check that the safety pins for the mast lock rod
and mast lock bar are present and secured with
a chain. Check that the spring located in the mast
lock bar is not broken or missing. Check the
operation of the mast lock bar.
Check the wheel lugs. Refer to
on page 22.
Check coolant levels. Refer to the engine oper-
ator's manual when determining proper mixture.
Coolant is checked visually by inspecting the level in coolant overflow jug near the radiator.
Normal operation is between the Full and Add markings on the overflow jug, this is known as "Normal
Range."
WHEN ENGINE IS STOPPED AND COMPLETELY COOL, coolant may be added directly to the jug.
Check the oil levels. Refer to the engine operator's manual when determining proper viscosity.
DO NOT start the unit if the engine oil level is below the Add mark on the dipstick.
Normal operation is between the Full and Add markings on the dipstick.
Add oil only if oil level is below cross-hatch pattern on the dipstick. DO NOT OVERFILL crankcase.
Check fuel level
Note: If the engine was run out of fuel or the fuel tank was drained, it may be necessary to bleed the fuel lines. Refer
to the engine operator's manual supplied with the unit.
