Operation and Maintenance Manual
General
In addition to periodic inspections, many of the
components in this unit requires periodic servicing to
provide maximum output and performance. Servicing
may consist of pre-operation and post-operation
procedures to be performed by the operating or
maintenance personnel.
The primary function of preventive maintenance is to
prevent failure, and consequently, the need for repair.
Preventive maintenance is the easiest and the least
expensive type of maintenance. Maintaining your unit
and keeping it clean at all times will facilitate servicing.
Scheduled Maintenance
The maintenance schedule is based on normal
operation of the unit. In the event unusual
environmental operating conditions exist, the schedule
should be adjusted accordingly. Refer to “Preventitive
maintenance schedule” on page 20
Wire Routing Clamps
Daily check for loose wire routing clamps. Clamps must
be secure and properly mounted. Also check wiring for
wear, deterioration and vibration abrasion.
Electrical Terminals
Check daily for evidence of arcing around the electrical
terminals.
Grounding Circuit
Daily check that the grounding circuit is in accordance
with local code requirements. Check to ensure
continuity between the grounding terminal, frame,
generator and engine block.
Hoses
Each month it is recommended that the intake hoses
from the air cleaner and all flexible hoses used for water
and fuel be inspected for the following:
1. All rubber hose joints and the screw type hose
clamps must be tight and the hoses showing no
signs of wear, abrasion or deterioration.
2. All flexible hoses must be free of wear, deterioration
and vibration abrasion. Routing clamps must be
secure and properly mounted.
Wiring Insulation
Daily check for loose, or frayed wiring insulation or
sleeving.
Fuel/Water Separator
Daily check for water in the fuel filter/water separator
unit (if equipped). Some engines have a translucent
bowl for visual indication, and others have a drain valve
below the primary element.
Every six months or 500 hours, or less if fuel is of poor
quality or contaminated, replace the fuel element(s).
Air Vents
Daily clean the air vents of any obstructions or debris.
Air Cleaner
Proper maintenance of the air cleaner provides
maximum protection against airborne dust. Squeeze
the rubber valve (precleaner dirt dump) periodically to
ensure that it is not clogged.

maintain this equipment may make it unsafe and
out of factory warranty.

engine battery cables and all leads to electrical
power requirements. Failure to do so can result in
severe personal injury, death or damage to the
equipment.
