Check the hydraulic oil
Check the hydraulic oil at every 100 hours’
operation. Keeping the handle at the oper-
ating position, remove the breather plug at
the top of the hydraulic hand pump to see
if the hydraulic oil is at the specified level
(OIL LEVEL). (Fig.62)

Stop the engine when inspecting or
changing the V belt.
Be careful not to have your hand or
clothes get caught between the V belt and
the clutch. Always wear work gloves.

Appropriate maintenance is required to
ensure safe and efficient operation of the
machine. Pay special attention to the parts
used for lifting, if they are not maintained
properly, it might result in a serious accident.
When checking the vibrator oil, clean the
oil port beforehand to prevent dust and
other foreign materials from falling into the
oil. Whenever there is an oil leakage from
the vibrator, check the oil level.
In case that oil is drained from Drain Plug,
some oil still remains in Oil Pan. So be
sure to check oil level correctly by Oil
Gauge after filling oil.
Do not fill oil with excessive volume
(600cc). It may cause the terrible fuel
consumption and lower machine perfor-
mance as the result of engine overload.
CAUTION
!
CAUTION
!
Be very careful not to have your fingers get
caught between the belt and clutch pulley.
There is a danger of injury. Also, wear
gloves when working.
Inspection of clutch
The clutch should be inspected at the time
of V-belt inspection. Remove the belt
cover and visually check the clutch for
burning, wearing, and damaging on the
clutch drum and its V groove.
Also, if its V groove is dirty, degrease and
clean it.
The clutch lining shoe wear should be
checked by operation inspection.
In case of wearing of the clutch lining
shoe, the engine power is not fully trans-
mitted to the vibrator by the clutch slip-
ping.
When stopping this inspection, move the
throttle lever to the low speed position at
once.
Change of clutch
move the V-belt.
(See belt removal of the previous section.)
Remove the bolt for assembling the clutch
with impact wrench or by hitting the
wrench with the hammer. (Counter-
clockwise)
Remove the clutch with the pulley puller.
Assemble with the reversed procedure of
disassembly.
When tightening the bolt for assembling
the clutch, tighten it with impact wrench or
by hitting the wrench with the hammer cer-
tainly.
At every 100 hours of operation, set the
machine on a level surface and remove
the oil gauge of the vibrator. Check the oil
level to see if it is within the allowable
range. (Fig.61)
Change the vibrator oil at every 300 hour
operation. Drain the oil from the drain
plug. For draining, put a beam under the
compacting board at the other side of the
drain plug to tilt the machine.
Use engine oil SAE 10W-30 as lubrica-
tion oil.The quantity used is 600cc.
