MAINTENANCE

CHECKING AND ADJUSTING VALVE LASH

Checking and adjusting valve lash
must be done when the engine is cold.
1. Remove the rocker arm cover and carefully remove
the gasket. If the gasket is torn or damaged, it must
be replaced.
2. Remove the spark plug so the engine can be rotated
more easily.
3. Rotate the engine to top dead center (TDC) of the
compression stroke. Looking through the spark plug
hole, the piston should be at the top.
4. Both the rocker arms should be loose at TDC on the
compression stroke. If they are not, rotate the engine
360°.
5. Insert a feeler gauge between the rocker arm and the
push rod and check for clearance (see Figure 24). See
Table 3 for valve lash specifications.

6. If an adjustment is required, hold the adjusting nut and
loosen the jam nut.
7. Turn the adjusting nut to obtain the correct valve lash.
When the valve lash is correct, hold the adjusting nut
and tighten the jam nut to 106 in-lb (12 N•m).
8. Recheck the valve lash after tightening the jam nut.
9. Perform this procedure for both the intake and
exhaust valves.
10. Install the rocker arm cover, gasket and spark plug.

TESTING GFCI OUTLETS

1. Start the generator and allow it to warm up.
2. Press the test button on the GFCI outlet.
3. The reset button should pop out and there will be
no power from the outlets. If the reset button does
4
not pop out, the GFCI outlet is not working correctly
and must be repaired before the generator can be
operated.
4. Press the reset button to restore power to the outlet.

BATTERY SERVICE

To ensure the battery remains charged, the generator
should be started every 2 to 3 months and run for a
minimum of 15 minutes or a charger should be plugged
into the generator and the generator should be charged
overnight. Make sure the engine control switch is in the
STOP position when charging. Plug the cord from the
charger into the charging port on the generator control
panel. Plug the charger into a 110/120-volt AC outlet.
