1. Turn off the excavator and relieve any trapped pressure in the hydraulic system. Lock-out / Tag-out the hydraulic
power source.
Do not connect or disconnect hydraulic lines while
they are pressurized. Escaping fluid under pressure
can penetrate the skin, causing serious injury.
Trapped hydraulic pressure may be present after
the excavator is shut off. Extreme caution must
be taken when removing hydraulic hoses or lines.
Injury or death could result.
2. Clean the excavator hydraulic hose fittings.
3. Route each hydraulic hose so that they will not rub on the attachment bracket or will otherwise become damaged.
