MVH-150GH/D — PARTS & OPERATION MANUAL — REV. #2 (12/04/06) — PAGE 19
Engine Oil Replacement:
1. Replace engine oil, first in 20 hours of operation and every
100 hours afterwards.
2. Oil may be drained more easily when it is warm after
operation (For more details, see separate HONDA Owner's
Manual).
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 16), 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.

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
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.
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.
CAUTION:
Whenever the compactor's vibration becomes
weak or lost during normal operation regard-
less of operation hours, check the V-belt and
clutch immediately.

Vibrator Oil Level Check
1. In every 300 hours of operation, with the machine positioned
horizontally, remove vibrator oil level check plug (Figure 5)
off vibrator (14 mm wrench) and see if oil is up to filler port.
Be sure to clean area around check hole to prevent dirt and
dust from entering.
2. In every 300 hours of operation, replace oil (capacity 400
cc). For draining oil through level check hole, have the
machine inclined with a sleeper or the like placed under the
compaction plate on opposite side.
* Use engine oil 10W-30 for this lubrication.
CAUTION:
Always clean the area around the vibrator oil
level check hole before removing oil check
plug. This will prevent dirt and debris from
entering the system.
CAUTION:
NEVER attempt to check the V-belt with the
engine running. Severe injury can occur if your
hand (Figure 7) 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.
