CAUTION: Escaping fluid under pressure can penetrate the skin, causing serious injury.
Avoid this hazard by relieving pressure before disconnecting hydraulic lines.
Hydraulic oil may be hot after operation and may spurt, possibly causing severe burns. Be sure to wait for oil to cool before starting any repair work.
The hydraulic oil tank cap may fly off due to remaining pressure if removed quickly.
Slowly loosen the cap to release any remaining pressure completely.
1. Park the machine on a solid level surface.
Lower the front attachment onto the ground.
2. Stop the engine. Loosen the cap on top of the hydraulic oil tank to release any remaining pressure.
3. Remove the hydraulic oil tank cap. Connect a vacuum pump and operate it continuously to maintain negative pressure in the hydraulic oil tank.
Run the vacuum pump continuously, while working on the hydraulic system.
