Coolant
With the engine cold, check the coolant level in the coolant
recovery bottle (see Controls). Specifications for the coolant
system can be found in the Maintenance chart of this
manual. Coolant Specification - ethylene-glycol 50-50
mixture with distilled water.
WARNING
Hot pressurized coolant can cause severe injury.
• DO NOT open radiator cap when hot.
• Before servicing, allow coolant to cool.
Engine Coolant System
It is important that the cooling system of the engine be
maintained properly to ensure proper performance and
longevity.
NOTICE
Alcohol or methanol based anti-freeze or plain water
are not recommended for use in the cooling system at any
time.
The cooling system must be maintained according to the
recommended maintenance schedule and inspection should
include:
• The regular removal of dust, dirt, debris from the
radiator core and fan shroud.
• Inspection of coolant hoses and components for leaks,
especially at the radiator hose connections. Tighten
hose clamps if necessary.
• Check radiator hoses for swelling, separation,
hardening, cracks, or any type of deterioration.
• Inspect the radiator cap to ensure proper sealing.
Once each year service the air cleaner, as follows. If
operating in a dusty environment, service more often.
1. Turn the generator off.
2. Remove control board fuse from control board.
3. Remove filter cartridge - Remove the service cover by
disengaging three clips and detaching cover, starting
with the bottom two clips and the top clip last. Gently
move the end of the filter back and forth, then rotate
while pulling straight out.
4. Clean outlet tube and check
Vacuator™ valve - Use a clean cloth
to wipe the filter sealing surface and
the outlet tube surfaces. Make sure
that all contaminant is removed
before the new filter is inserted. Be
careful not to damage the sealing
area on the tube.
Visually check and physically squeeze Vacuator valve
attached to service cover to make sure it is flexible
and not inverted, damaged or plugged.
5. Clean filter - Use a soft bristle brush to loosen dirt
and a vacuum cleaner to remove dirt and debris. Low
pressure air (not to exceed 25 psi) may also be used
to blow away dirt. Replace filter cartridge if any holes
are detected in filter media.
6. Install clean filter properly - Insert the filter carefully.
Seat the filter by hand, making certain it is completely
into the air cleaner housing before securing the cover
in place. To complete a tight seal, apply pressure
by hand at the outer rim of the filter, not the flexible
center. (Avoid pushing on the center of the urethane
end cap.) No cover pressure is required to hold
the seal.
NEVER use the service cover to push the filter into
place! Using the cover to push the filter in could cause
damage to the housing, cover, or fasteners and will
void the warranty. If the service cover hits the filter
before it is fully in place, remove the cover and push
the filter (by hand) further into the air cleaner and try
again. The cover should go on with no extra force.
7. Reinstall service cover - Once the filter is in place,
reinstall the service cover, positioning the cover with
the arrow and the word TOP to the top. Fasten the
top clip first, the bottom two clips last. Make sure that
all mounting bands, clamps, bolts, and connections
in the entire air cleaner system are tight and verify
absence of holes in piping - repair if needed.
8. Reinstall control board fuse in control board.
9. Turn the generator on and place in AUTO mode.
