7. Replacing the hydraulic oil:
24
After draining hydraulic oil, reinstall the hydraulic hose to vibrator.
Feed hydraulic oil through breather plug of the hand pump.
Hydraulic oil capacity: R-60 Series: 0.26 Liter
100/150 Series: 0.30 Liter
Shortly after removing breather plug at the vibrator cylinder, oil starts to flow out of the plug hole. Wait
until aeration disappears before replacing the plug. Tighten it securely. (See Fig.37)
Install breather plug to hand pump and fit the plug cap. Breather plug should be reinstalled only after
making sure that hydraulic oil in the pump is up to OIL LEVEL.
Hydraulic oil to use: Shell Tellus Oil #46 or its equivalent
Change the oil at first 200 hours and in every 1,000
hours of operation thereafter.
With the plug cap taken off the hand pump, remove
breather plug (with 24mm wrench) before discon-
necting hydraulic hose which has entered vibrator
cylinder at the vibrator side, and with the travel lever
placed in forward position, drain the hydraulic oil.
Be careful not to allow any dust to
enter the hand pump during the work.
NOTE:
！
Be sure to fill the hydraulic oil exactly to the OIL LEVEL. Excessive filling causes
oil to gush out of the breather.
