Checking and Replacing the V-Belt and Clutch

1. After 200 hours of operation, remove the upper belt cover to

check the V-belt tension. 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.



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

deficient and slipping will result.



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 upper and lower belt covers. Engage an offset

wrench (13 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.

Changing Vibrator Oil

1. When changing the vibrator oil, remove the drain plug

located at the bottom- right of the vibrator (Figure 5), and

simply tip the compactor to drain the oil. Note that the oil will

drain more easily while it is hot. Remember to use only

10W-30 motor oil when replaceing vibrator 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 15), 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.

MAINTENANCE

CAUTION

NEVER attempt to check the V-belt with the engine running.

Severe injury can occur if your hand (Figure 6) gets caught

between the V-belt and the clutch. Always use safety gloves.

CAUTION

Whenever the compactor's vibration becomes weak or lost

during normal operation regardless of operation hours, check

the V-belt and clutch immediately.
