• Loosen the rocker jam nut. Use an 10mm allen
wrench to turn the pivot ball stud while checking
clearance between the rocker arm and the valve
stem with a feeler gauge. Correct clearance is
0.002-0.004 inch (0.05-0.1 mm).
NOTE:
Hold the rocker arm jam nut in place as the pivot
ball stud is turned.
When valve clearance is correct, hold the pivot ball
stud in place with the allen wrench and tighten the
rocker arm jam nut. Tighten the jam nut to 174
in.lbs. torque. After tightening the jam nut, recheck
valve clearance to make sure it did not change.

• Install new valve cover gasket.
• Re-attach the valve cover.
NOTE:
Start all four screws before tightening or it will not
be possible to get all the screws in place. Make
sure the valve cover gasket is in place.
• Re-attach the spark plug wire to the spark plug.
• Repeat the process for the other cylinder.
4.9 COOLING SYSTEM
Air inlet and outlet openings in the generator com-
partment must be open and unobstructed for con-
tinued proper operation. This includes such obstruc-
tions as high grass, weeds, brush, leaves and snow.
Without sufficient cooling and ventilating air flow, the
engine/generator quickly overheats, which causes it
to quickly shut down. (See Figure 4.7 for vent loca-
tions.)

The exhaust from this product gets extremely
hot and remains hot after shutdown. High grass,
weeds, brush, leaves, etc. must remain clear of
the exhaust. Such materials may ignite and burn
from the heat of the exhaust system.

The maximum ambient temperature for the gen-
erator is 40° C (104° F).
4.10 ATTENTION AFTER SUBMERSION
If the generator has been submerged in water,
it
MUST NOT be started and operated. Following any
submersion in water, have an Authorized Dealer thor-
oughly clean and dry the generator.
4.11 CORROSION PROTECTION
Periodically wash and wax the enclosure using auto-
motive type products. Frequent washing is recom-
mended in salt water/coastal areas. Spray engine
linkages with a light oil such as WD-40

4.12 OUT OF SERVICE PROCEDURE
4.12.1 REMOVAL FROM SERVICE
If the generator cannot be exercised every seven days,
and will be out of service longer than 90 days, pre-
pare the generator for storage as follows:
1. Start the engine and let it warm up.
2. Close the fuel shutoff valve in the fuel supply line
and allow the unit to shut down.
3. Once the unit has shut down, it will signal a low
oil fault.
4. Set the AUTO/OFF/MANUAL switch to OFF and
turn off the utility power to the transfer switch.
Remove the 7.5A and 15A fuses from the genera-
tor control panel. Disconnect the battery cables
as outlined in “General Hazards” (page 2).
5. While the engine is still warm from running,
drain the oil completely. Refill the crankcase with
oil. See ”Engine Oil Recommendations,” Section
4.3.1.
6. Attach a tag to the engine indicating the viscosity
and classification of the oil in the crankcase.
