CLEANING THE GENERATOR
It is important to inspect and clean the generator after
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 obstructions.
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.
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 Figure 24). See
Table 3 for valve lash specifications.
