Adding hydraulic oil
Warning!
Pressurized hydraulic oil hazard. Removing the hydraulic filter plug can cause
pressurized oil to escape. Escaping oil may cause serious injuries.
• Permit the hydraulic oil to cool to a temperature that is comfortable to the
touch.
• Slightly loosen the breather plug on the hydraulic reservoir enough to
relieve pressure in the tank.
Do not fill up the hydraulic oil unless the engine is stopped. Otherwise, hydraulic oil will
overflow at the filler opening on the hydraulic reservoir.
☞
Fill up as follows:
• Park the machine on level ground
• Retract the bucket and boom hydraulic cylinders, lower the boom and the bucket
teeth to the ground
• Lower the stabilizer blade to the ground
• Set the boom straight (offset ram)
• Stop the engine
• Fold the control lever base up
• Let the engine cool down
• Slowly open cap
