Changing Vibrator Oil / Vibrator Grease
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. For
SP
series
compactors,
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.
CAUTION:
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.
Never run the machine
without the belt cover as similar injury may occur.
z
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 reduces power
transmission efficiency, causing
reduced
compaction and
shortens
the life of the belt itself.
CAUTION:
If
the compactor’s vibration
reduces
or
eliminates entirely
during normal operation, check the
V-belt and clutch immediately.
z
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.
z
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.
z
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.
