MAINTENANCE
1. Replace engine oil, in first 25 hours of operation and
every 50 to 100 hours afterwards.
2. Oil may be drained more easily when it is warm
afteroperation (For more details, see separate engine
Owner's Manual).
1. The air filter element (Figure 30) should be cleaned
because a clogged air cleaner can cause poor
engine starting, lack of power and shorten engine life
substantially.
Figure 30. Engine Air Filter and Element
2. To clean or replace air filter loosen the wing nut on the
air filter housing (Figure 30) remove the cover and take
out air filter cartridge. If only cleaning of the air filter
is desired blow through the air filter cartridge from the
inside, moving a jet of dry compressed air up and down
until all dust is removed.
Figure 31. V-Belt Hazard
attempt to check the V-belt with the engine
running. Severe injury can occur if your hand gets
caught between the V-belt and the clutch (Figure 31).
Always use safety gloves.

Figure 32. V-Belt Check
Remove the belt cover (Figure 32). Engage an offset
wrench 3/4”(19 mm) or the like to vibrator pulley (lower)
fastening bolt. Engage wastecloth or the like at midway
of V-belt on the left side and whilepulling it back strongly,
rotate the offset wrench clockwise so that the V-belt will
come off.
Engage V-belt to lower vibrator pulley and push the V-belt
to leftside of upper clutch and, in the same manner as
in removal, rotate offset wrench clockwise so that the
V-belt goes back on.
Check the clutch simultaneously with V-belt checking.
With belt cover removed, check outer drum of the clutch
for seizure and "V" groove for wear or damage with your
eyes. Clean the "V" groove as necessary. If the shoe is
worn, power transmission becomes deficient and slipping
will result.
Replacing Clutch
Remove V-belt. Remove bolt at engine power output by
giving a light tap with a hammer to an engaged wrench
and rotate bolt counterclockwise. Remove clutch with a
pulley extractor. To reinstall, reverse the procedure.
