Every 600 hours, change the primary fuel filter by remov-
ing the washer and capscrew on top of the fuel filter body.
Every 3000 hours, change the secondary fuel filter in the
same manner as the primary fuel filter.
Fuel presents the hazard of fire or ex-
plosion that can cause severe personal injury or
death. Do not work on the fuel system when the gen-
erator set is hot. Clean fuel spills and allow vapor to
evacuate prior to starting the generator set.
GOVERNOR LINKAGE
Every 100 hours, carefully pull the neoprene governor
ball joints apart and clean them. Do not lubricate these
joints. See Figure 7-2.

CLEAN BALL JOINT
Some solvents can damage the neo-
prene governor ball joints. Read the manufacturer’s
recommendations before using any lubricants or
solvents near the ball joints.
Fumes from this cleaner may present
the hazard of fire or explosion, which can cause se-
vere personal injury or death. Do not allow any
spark, flame, pilot light, lit cigarette, arc-producing
equipment or other ignition source near the genera-
tor set when performing this procedure. Keep a fire
extinguisher rated ABC near the work area.
CRANKCASE BREATHER TUBE
To clean the crankcase breather tube, remove both
rocker covers, as shown in Figure 7-3. The breather tube
itself is installed with a sealant on the threads to prevent
oil leakage into the intake manifold: it should NOT be re-
moved. A small wire, nail or drill bit inserted through from
the top can be used to clean out the breather hole. The
breather hole seldom needs cleaning: a 500 hour interval
coincides with the valve lash adjustments, because the
rocker box covers must be removed at that time.
