Engine Air Cleaner

1. Set control board system switch to OFF.
2. Remove 15 Amp fuse from control panel.
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 to
not 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. Replace 15 Amp fuse in control panel.
9. Set control panel system switch to ON.

Electrical System Maintenance

Wiring and Connections

The generator electrical system incorporates computers
to control various components. The electrical system
connectors and grounds require good connections. When
inspecting the electrical system, check the following:
• Check positive (+) and negative (-) battery cables for
corrosion, rubbing, chafing, burning, and ensure tight
connections at both ends.
• Check battery for cracks or damage to the case.
Replace as necessary.
• Inspect engine wire harness for rubbing, chafing,
pinching, burning, and cracks or breaks in the wiring.
• Verify that the engine harness connectors are correctly
locked in.
• Inspect ignition coil wire for hardening, cracking,
chafing, burning, separation, and split boot covers.
• Inspect spark plug wires for hardening, cracking,
chafing, burning, separation, and split boot covers.
• Replace spark plugs at the required intervals listed in
the maintenance chart.
• Verify that all electrical components are securely
mounted to the engine or chassis.
• Verify that any additional electrical services installed by
the owner are properly installed in the system.
Servicing the Battery
Servicing of batteries is to be performed or supervised
by personnel knowledgeable of batteries and the
required precautions. Keep unauthorized personnel away
