before starting works with the vessel raised.
Oil is hot immediately after operation. You may
•
get burnt if you touch oil. Start work after oil
has cooled down.
1. Place the machine on a flat and rigid ground and bring
it into the posture for changing hydraulic oil. Stop the
engine.
2. Discharge hydraulic oil through the filler port (1) into an
empty drum with an oil pump.
3. Put the container under the drain plug (2) at the bottom
of the hydraulic oil tank, and remove the drain plug to
discharge residual oil.
Tighten the drain plug after discharging oil.
4. Disconnect the hose from the tube (3). Remove the
bolt (4) and take out the strainer (5).
5. Clean the strainer (5) to remove dust and foreign
matters.
6. Attach the strainer in the reverse order to step 4.
7. Fill the tank with hydraulic oil through the filler port up
to the L level of the level gauge (6). Tighten the filler
port plug.
8. Store the safety bars and start the engine. Keep the
engine running with no load for approximately 5
minutes. Travel the machine and move the dump
cylinder slowly several times. Bring the machine into
the posture for checking the hydraulic oil level. Stop
the engine.
9. Make sure that the hydraulic oil level is within the
proper range. Refill hydraulic oil if insufficient.
