4.  Attach a tag to the engine indicating the viscosity 

and classification of the oil in the crankcase.

5.  Remove the spark plug and pour two or three 

tablespoons of clean, fresh engine oil into the 
spark plug threaded openings. Reinstall and 
tighten the spark plug.

6.  Remove the battery and store it in a cool, dry 

room on a wooden board. Never store the battery 
on any concrete or earthen floor.

7.  Clean and wipe the entire generator.

To return the unit to service after storage, proceed 
as follows:

1.  Check the tag on the engine for oil viscosity and 

classification. Verify that the correct recom-
mended oil is used in the engine (see "Engine Oil 
Requirements"). If necessary, drain and refill with 
the proper oil.

2.  Check the state of the battery. Fill all cells of 

unsealed batteries to the proper level with dis-
tilled water. DO NOT USE TAP WATER IN THE 
BATTERY. Recharge the battery to 100 percent 
state of charge, or, if defective, replace the battery.

3.  Clean and wipe the entire generator.
4.  Reconnect the battery. Observe battery polarity. 

Damage may occur if the battery is connected 
incorrectly.

5.  Turn OFF all electrical loads. Add fuel if neces-

sary and then start the engine.

6.  Allow the unit to run for several minutes to warm 

up.

7.  Apply electrical loads to at least 50 percent of the 

unit’s rated wattage capacity.

8.  When the engine is thoroughly warmed up, shut 

it down.

9.  The generator is now ready for service.

After the first 50 hours of operation, adjust the valve 
clearance in the engine.

When adjusting valve clearance, the engine should be 
at room temperature and the piston should be at Top 
Dead Center (TDC) of its compression stroke (both 
valves closed). Correct clearance is 0.001-0.003 inch 
(0.03-0.07mm). Adjust valve clearance as follows:

1.  Loosen the rocker arm jam nut. Use an allen 

wrench to turn the pivot ball stud while checking 
clearance between the rocker arm and the valve 
stem with a feeler gauge (Figure 3.7).

2.  When valve clearance is correct, hold the pivot 

ball stud with the allen wrench and tighten the 
rocker arm jam nut with a crows foot. Tighten 
the jam nut to 65-85 inch-pounds torque. After 
tightening the jam nut, recheck valve clearance to 
make sure it did not change (Figure 3.8).
