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
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.
NOTICE
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.
1. Make sure the Engine Switch is switched to
STOP
so the generator does not draw power from battery.
2. Clean the generator as outlined in
Cleaning the
Generator
.
3. Drain all gasoline from the fuel tank as best as
possible.
4. Drain fuel out of carburetor bowl by loosening screw.

CHECKING AND ADJUSTING VALVE LASH
CAUTION
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 Table below for valve lash
specifications
(1) Push Rod, (2) Feeler Gauge Area
(3) Rocker Arm, (4) Jam Nut, (5) Adjusting Nut

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.
