Changing the hydraulic oil
Remove the plug cap of the hand pump.
Then remove the breather plug (with 24mm
wrench) before removing the hydraulic hose
connected to the cylinder on the vibrator
side. Set the control lever to forward, then
drain the hydraulic oil from the pump.
(Fig.38, 39)
After the oil is drained, attach the hydraulic
hose again to the cylinder on the vibrator
side.(Fig.39)
Pour hydraulic oil(300cc) from the hand
pump breather plug attachment hole.
(Fig.38)
The level of the hydraulic oil in the hand
pump should always be at OIL LEVEL. If the
level is higher, the oil bursts out from the
breather plug.
Be careful not to let dirt enter the hand pump
during inspection or replacement. It may
become malfunctioning when dust is mixed in.
.
Remove the air vent plug of the cylinder of the
vibrator side. After a while oil will come out,
so plug bubbles will be installed when bubbles
run out. Please firmly tighten.(Fig.33)
Attach the hand pump breather plug, put on
the plug cap. After making sure the hydrau-
lic oil in the pump is at OIL LEVEL, attach
the breather plug.

11.6 Checking/Changing The vibrator Oil
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.37)
Change the vibrator oil at every 300 hour
operation. Drain the oil from the drain plug.
For draining, put a beam under the com-
pacting 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.
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 con-
sumption and lower machine performance
as the result of engine overload.
Check the hydraulic oil
Check the hydraulic oil at every 100 hours’
operation. By making the handle bar verti-
cal (done at the time of storage), 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).
