Oil Filter - Generac Power Systems 004988-2 Owner's Manual

DANGER
Do not attempt to adjust the governor. Only
!
qualified service facilities should adjust the
governor. Excessively high operating speeds are
dangerous and increase the risk of personal
injury. Low speeds impose a heavy load on the
engine when adequate engine power is not
available and may shorten engine life. Correct
rated frequency and voltage are supplied only
at the proper governed speed. Some connected
electrical load devices may be damaged by
incorrect frequency and/or voltage. Only quali-
fied service technicians should adjust the gov-
erned speed.

the air filter making sure it is positioned properly
before reattaching the cover (Figure 4.3).

maintenance.
4.5.12 SPARK PLUGS
Reset the spark plug gap or replace the spark plugs
as necessary. See Section 6.
1. Clean the area around the base of the spark plugs
to keep dirt and debris out of the engine. Clean by
scraping or washing using a wire brush and com-
mercial solvent. Do not blast the spark plugs to
clean.
2. Remove the spark plugs and check the condition.
Replace the spark plugs if worn or if reuse is
questionable. See the "Service Schedule," Section
6, for recommended inspection.
3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 1.06-1.16 mm (0.042-
0.046 inch) by carefully bending the ground elec-
trode (Figure 4.4).
