MAINTENANCE
4.3 V-belt and Clutch
4.3.1 Checking the V-belt
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 reduces power transmission efficiency, causing
weak compaction and reduces the life of the belt itself.
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.
4.3.2 Replacing the V-belt
Remove the 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.
4.3.3 Checking the 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.
Whenever the compactor
’
s vibration becomes weak or lost during
normal operation regardless of operation hours, check the V-belt and
clutch immediately.
4.4 Air Cleaner
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.
