Tigercat 718 Feller Buncher SERVICING SAFETY PRECAUTIONS continued 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 electrical current does not pass through bearings, especially the center joint bearing.
Safety 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.
This machine is equipped with sensitive electronic control equipment, prior to welding:-
Never use bare hand to check for fluid leaks. 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 Battery Disconnect Switch to the OFF position and disconnect the engine ground cable from chassis frame.

Pressure can be maintained in a hydraulic system long after the power source and pump have been shut down. Lower the felling head to the ground, stop engine and relieve trapped pressure from pilot system and brake accumulators before performing work on components, or disconnecting any hoses. For the procedure on how to RELIEVE PRESSURE, refer to PARKING THE MACHINE in THIS SECTION.
DISCONNECT MULTI PIN CONNECTORS
Disconnect the engine CPU (Central Processing Unit) and engine wiring harness by unplugging the multi-pin connector from the engine CPU. Explosive release of fluids from pressurized cooling system can cause serious burns. Shut off engine. Only remove filler cap when cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely. Do not change any pressure or relief setting unless authorized instruction has been obtained. Use the proper tool for the job. Repair or replace worn or damaged tools including lifting equipment immediately. 1.11
