Do not connect or disconnect hydraulic lines while
they are pressurized. Escaping uid under pressure
can penetrate the skin, causing serious injury.
Trapped hydraulic pressure may be present after
the excavator is shut o. Extreme caution must
be taken when removing hydraulic hoses or lines.
Injury or death could result.
