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
25). See Table 2 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 ad-
justing 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.
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 the charger (included) should
be plugged into the generator and the generator should
be charged overnight. Make sure the engine control
switch is in the "RUN" position when charging. Plug the
cord from the charger into the charging port on the gen-
erator. Plug the charger into a 110/120-volt AC outlet.
CLEANING THE GENERATOR
It is important to inspect and clean the generator before
every use.
Clean All Engine Air Inlet and Outlet Ports – Make
sure all engine air inlet and outlet ports are clean of any
dirt and debris to ensure the engine does not run hot.
Clean All Engine Cooling Fins – Use a damp rag and
a brush to loosen and remove all dirt on or around the
engine's cooling fins.

Clean All Alternator Cooling Air Inlets and Exhaust
Ports – Make sure the cooling air inlets and exhaust
ports of the alternator are free of any debris and ob-
structions. Use a vacuum cleaner to remove dirt and
debris stuck in the cooling air inlets and exhaust ports.
General Cleaning of the Generator – Use a damp rag
to clean all remaining surfaces.
STORING GENERATOR
Gasoline stored for as little as 60 days can go bad, causing gum,
varnish and corrosive buildup in fuel lines, fuel passages and the
engine. This corrosive buildup restricts the flow of fuel, preventing
an engine from starting after a prolonged storage period.
Proper care should be taken to prepare the generator for
any storage.
WARNING
Never store a generator with fuel in the tank
indoors or in a poorly ventilated area where the
fumes can come in contact with an ignition source
such as a: 1) pilot light of a stove, water heater,
clothes dryer or any other gas appliance; or 2)
spark from an electric appliance.
