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
takeout 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 15. Air Filter
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.
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.
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 (13 mm) or the Ike 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 oil.
• 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.
• 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.
• Engine maintenance
Refer to the Engine Manual included in your plate compactor for the information on engine maintenance.
Your engine manual provides detailed information for performing the tasks.
