Engine Oil Replacement:
1. Replace engine oil, first in 25 hours of operation and every
50 to 100 hours afterwards.
2. Oil may be drained more easily when it is warm after
operation (For more details, see separate engine Owner's
Manual).
Air Filter
1. The air filter element should be cleaned because a clogged
air cleaner can cause poor engine starting, lack of power
and shorten engine life substantially.
2. To clean or replace air filter loosen the wing nut on the air
filter housing (Figure 18), 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.

Reinstalling the V-belt
Engage V-belt to lower vibrator pulley and push the V-belt to left
side of upper clutch and, in the same manner as in removal,
rotate offset wrench clockwise so that the V-belt goes back on.

Replacing the V-belt
Remove the belt cover. Engage an offset wrench (19 mm) or the
like to vibrator pulley (lower) fastening bolt. Engage waste cloth
or the like at midway of V-belt on the left side and while pulling it
back strongly, rotate the offset wrench clockwise so that the V-
belt will come off.

Checking Clutch
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. Wear of lining or shoe should be checked
with running check. 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
shock to an engaged wrench (tapping with hammer or the like)
and rotating bolt counterclockwise. Remove clutch with a pulley
extractor. To reinstall, reverse the procedure.

Checking and Replacing the V-Belt and Clutch
1. After 200 hours of operation, remove the belt cover to check
the V-belt tension (Figure 20). Tension is proper if the belt
bends about 10 mm when depressed strongly with finger
between shafts. Loose or worn V-belts reduces power
transmission efficiency, causing weak compaction and
reduces the life of the belt itself.

WARNING
NEVER attempt to check the V-belt with the engine run-
ning. Severe injury can occur if your hand (Figure 5) gets
caught between the V-belt and the clutch. Always use
safety gloves.
Whenever the compactor's vibration becomes weak or lost
during normal operation regardless of operation hours, check
the V-belt and clutch immediately.
