HYDRAULIC TANK
DISASSEMBLY AND ASSEMBLY
Refilling
Important:
Do not refill to above the (H) mark. This can
result in damage to the hydraulic circuit or cause oil to
spurt out. If accidentally filled to above the (H) mark,
stop the engine, and after allowing the hydraulic oil to
cool off, drain the excess oil from the drain plug.
Important:
Failure to pressurize the hydraulic tank will
cause the pump to suck in air, which will adversely af-
fect the hydraulic units.
1. Open the fuel lid.
2. Slowly loosen the air-bleeding plug (2) to relieve the in-
ternal pressure, and then remove it.
<Models with air breather>
Open the side cover, press the button (3) to relieve the
internal pressure from the tank.
3. Add hydraulic oil up to the middle of the sight gauge
(1).
4. Pressurize the hydraulic oil tank according to the fol-
lowing procedure:
• The hydraulic tank of models with air breather does
not need to be pressurized.
Pressurizing the hydraulic tank
1. Start the engine and run it at low speed.
2. Remove the air-bleeding plug (2), and then place the
safety lock lever in the released position.
• Setup for pressurizing the hydraulic tank
3. Fully extend bucket, arm, boom and swing cylinders.
(Tank pressurizing setup)
4. Stop the engine and place the safety lock lever in the
locked position.
5. Tighten the air-bleeding plug (2) and start to pressurize.
(Retract the cylinders to start pressurizing)
