Maintenance
When valve clearance is correct, hold the pivot ball stud in
place with the allen wrench (10mm for 3.6kW/10kW, 13mm for
6.5kW/8kW) 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.
2. Install new valve cover gasket.
3. Re-attach the valve cover.
Figure 27 - Valve Clearance Adjustment
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. Replace spark plug(s).
4. Re-attach the spark plug wire(s) to the spark plug(s).
5. Repeat steps for cylinder #2 on 10kW units.

3.5 GENERAL

The generator should be started at least once every 30 days and
be allowed to run at least 30 minutes. If this cannot be done and
the unit must be stored for more than 30 days, use the following
information as a guide to prepare it for storage.


NEVER store engine with fuel in tank indoors or in
enclosed, poorly ventilated areas where fumes may reach
an open flame, spark or pilot light as on a furnace, water
heater, clothes dryer or other gas appliance.
Allow unit to cool entirely before storage.

NOTE:

3.6 LONG TERM STORAGE

It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose or tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during storage. Acidic
gas can damage the fuel system of an engine while in storage.
• If it is not practical to empty the fuel tank and the unit is to be
stored for some time, use a commercially available fuel stabilizer
added to the gasoline to increase the life of the gasoline.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer, as follows:
1. Remove all gasoline from the fuel tank. Use a commercially
available, non-conductive vacuum siphon.


Drain fuel into approved container outdoors, away from
open flame. Be sure engine is cool. Do not smoke in the
vicinity or light a cigarette.
2. Start and run engine until engine stops from lack of fuel.
3. After the engine cools down, drain oil from crankcase. Refill
with recommended grade.
4. Remove spark plug(s) and pour about 1/2 ounce (15 ml) of
engine oil into the cylinder(s). Cover spark plug hole(s) with
rag. Pull the recoil starter a couple times to lubricate the piston
rings and cylinder bore(s).
For the 10kW portable, crank the engine over by holding down
the ignition start switch for a few seconds.
Avoid spray from spark plug hole(s) when cranking

engine.
5. Install and tighten spark plug(s). Do not connect spark plug
wire(s).
6. Clean the generator outer surfaces. Check that cooling air
slots and openings on generator are open and unobstructed.
7. Store the unit in a clean, dry place.
8. Do not store gasoline from one season to another.
9. Cover the unit with a suitable protective cover that does not
retain moisture.
NEVER cover the generator while engine and exhaust

area are warm. Allow unit to cool entirely.
