OPERATING SAFETY PRECAUTIONS continued
When travelling on public roads, use accessory lights (when installed) and other cautionary devices to provide operators of other vehicles warning of your approach. Ensure your machine meets all regulatory requirements. When transporting the machine watch that enough clearance is available on both sides and above the machine or any of its attachments to avoid contact with power or telephone lines, bridge structures, etc. Before transporting the machine check to ensure that all doors, panels and access covers are installed properly and secured. Read, understand and follow all operating safety precautions specified by felling head manufacturer.

CAUTION
The steering system is always LIVE when engine is running. DO NOT use the steering wheel to assist entering or leaving the cab.
CAUTION All functions on the machine can now be operated, either as intended or by accidentally touching them.
INTERLOCK SWITCHES ON DOORS:
Both doors are equipped with interlock switches to prevent the machine from being operated while the doors are open (pilot system shut off).
NOTE: The engine can be started but the machine functions cannot be operated with a door open.
To operate:
Close both doors and press the pilot reset switch.
Once the safety interlock system has been activated, the safety of both the operator and all persons outside the cab will become the responsibility of the operator. The door interlock switches and the pilot reset switch are a safety feature and their function must not be defeated in any way.

The radiator and the engine cooling system should be cleaned and serviced daily to maintain moderate engine temperatures. 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 center joint bearing. Also, disconnect the positive (+) battery cable from both batteries.

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
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.
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.
Pressure can be maintained in a hydraulic system long after the power source and pump have been shut down. Stop engine lower the felling head to the ground and relieve trapped pressure (from two accumulators) by operating brake pedal 30 or more times while operating both joysticks several times before performing work on components, or disconnecting any hoses.
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.
