Changing Vibrator Oil
When changing the vibrator oil, remove the drain plug located at
the bottom-right of the vibrator, and simply tip the compactor to
drain the oil. Note that the oil will drain more easily while it is hot.
Replace the oil with 200ML of 10W-30 motor oil.
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 1),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.

NEVER 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. Always use safety gloves.
Checking and Replacing the V-belt and Clutch
After 200 hours of operation, remove the upper belt cover to
check the V-belt tension (Figure 2).Tension is proper if the belt
bends about 10mm when depressed strongly with finger between
shafts. Loose or worn V-belts reduce power transmission
efficiency, cause weak compaction and reduces the life of the belt
itself.
CAUTION:
Whenever the compactor's vibration becomes weak
or lost during normal operation regardless of
operation hours, check the V-belt and clutch
immediately.
Replacing the V-belt
Remove the upper and lower belt covers, Engage an offset
wrench (13mm) 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.
Reinstalling the V-belt
Engage V-belt to the lower vibrator pulley and push the V-belt to
the 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.
Checking Clutch
Check the clutch simultaneously with V-belt checking. With belt
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
