MAINTENANCE

ENGINE OIL REPLACEMENT

1. Replace engine oil, in first 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 17). 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.

CHECKING AND REPLACING 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 reduce
power transmission efficiency, causing weak
compaction and reducing the life of the belt itself.

Figure 17. Air Filter

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

CAUTION

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.

Reinstalling the V-belt

Engage V-belt to lower vibrator pulley and push the V-belt
to left side of upper clutch. 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, visually check outer drum of the clutch for
seizure and "V" groove for wear or damage. Clean the "V"
groove as necessary. Regularly check the lining or shoe
for wear. If the shoe is worn, power transmission becomes
deficient and slipping will result.

VIBRATOR OIL LEVEL CHECK

1. In every 300 hours of operation, with the machine

positioned horizontally, remove vibrator oil level check
plug (Figure 6) 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.

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.
