CRANKCASE BREATHER
Clean the crankcase breather cap and valve
assembly, and the breather tube baffle in a solvent
every 200 operational hours. To remove breather cap
and valve assembly, remove breather hose clamp and
breather tube clamp. Soe Figure 19,
SPEED BOOSTER
Use a fine wire to clean the small hole in the short
vacuum tube which fits into the hole in the top of the
engine intake manifold. Do not enlarge this hole. If
there is tension on the external spring when the unit is
operating at no load or light load, it may be due to
improper adjustment, restricted hole in the small
vacuum tube, or a leak in the booster diaphragm or
gasket. See Figure 2u.
FUEL FILTER (Where Applicable)
Every 100 hours, remove the fuel sediment bowl,
empty, clean and dry (Figure 21). Remove the screen
and clean any particles trapped. When replacing the
sediment bowl, be sure the screen and gaskets are in
place.

GENERATOR MAINTENANCE
The generator normally needs little care other than a
periodic check of the brushes, commutator and
collector rings. If a major repair job on the generator
should become necessary, have the equipment
checked by a competent electrician who is thorough¬
ly familiar with the operation of electric generating
equipment.
