SERVICING SAFETY PRECAUTIONS Continued
WARNING Diesel fuel or hydraulic fluid under pressure can penetrate the skin and cause serious personal injury, blindness, or death. If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with treating this type of injury.
Prior to welding on any part of the machine, it should be cleaned and a fire extinguisher should be made available at the welding location. Care must be taken in attaching the welding machine grounding clamp so current does not pass through bearings, especially the swing bearing.
Never use your bare hand to check for fluid leaks. 250BTH-002
Fluid leaks under pressure may not be visible. When searching for leaks, wear work gloves and use a wrench or piece of wood to move hydraulic hoses. Do not grab hold of hydraulic hoses. Wear safety goggles for eye protection.
Turn the battery disconnect switch off and disconnect the battery negative terminal. Also, disconnect the engine ground connection from the frame.
DISCONNECT THE 2 MULTI-PIN PLUGS FROM THE ENGINE ECM
Pressure can be maintained in a hydraulic system long after the power source and pump have been shut down. Lower the attachment to the ground, stop engine and relieve trapped pressure before performing work on components, or disconnecting any hoses. Accumulators will self drain within 2 minutes of stopping the engine.
