1. Be sure that the machine is parked on a level, firm surface before servicing hydraulic equipment.
2. Lower the bucket to the ground and stop the engine.
3. Begin servicing hydraulic equipment only after components, hydraulic oil and lubricant are completely cooled, as they will remain hot and pressurized soon after operation. While servicing heated and pressurized hydraulic equipment, hot parts or oil may fly off or escape suddenly with a potential of serious injury. Keep body parts and face away from plugs or screws when removing them as they may be pressurized even when cooled.
4. Before servicing hydraulic equipment, bleed air from the hydraulic oil tank to release internal pressure.
5. Even after bleeding the air from the hydraulic oil tank, pressure remains in the various circuits of the hydraulic system. Be sure to operate each control lever a few times to release residual pressure from the system.
6. Avoid inspecting and servicing the travel and swing motor circuits on slopes, as they are pressurized by gravity even after bleeding the hydraulic oil tank.
