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.
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.

Never use your 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.
Explosive release of fluids from the pressurized cooling system can cause serious burns. Shut off engine. Only remove engine radiator 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.

Keep your hands, feet, head, and loose clothing away from power driven parts. Tie long hair behind your head. Remove rings and other jewellery to prevent electrical shorts and entanglement in moving parts. Always be aware of machine pinch points that could cause injury. Never place body parts within the range of motion of the working parts of the machine. Never stand under an object supported with hydraulics. Always use safety stands or a locking device. Before performing work on the grapple or boom, ensure they are firmly supported.
If the engine is running inside a building, ensure that sufficient ventilation is available to prevent a buildup of toxic exhaust fumes. Run the engine only when it is necessary for testing or adjustments. Work in a ventilated area. If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to remove toxic exhaust fumes. If you don't have an exhaust pipe extension, either work outside, or open the shop doors. Dispose of all fluids properly according to all applicable laws and regulations for the region. Do not pour fluids into the ground, stream, pond or lake. Before draining any fluids, know the proper way to dispose of them.

Hydraulic and diesel fuel systems on forestry machines operate at very high pressures, often 207 bar (3000 psi) and above. If a loose connection or a defect in a hose should occur, a fine, high velocity stream of fluid will result. Even for systems pressurized to as little as 7 bar (100 psi), this fluid stream can penetrate human skin as if it were a hypodermic needle.
Initially, an accidental fluid injection beneath the skin may only produce a slight stinging sensation. There is a danger that you will tend to ignore this, thinking that it will get better with time. Most often, it does not! Within a very short time the wound may begin to throb painfully, indicating that tissue damage has already begun. Similarly fluid injected directly into a blood vessel can spread rapidly through your circulatory system. The human body has little ability to purge injected fluid. Diesel fuel or hydraulic fluid under pressure can penetrate the skin and could result in death or serious injury. If any fluid is injected under the skin, a medical doctor familiar with the treatment of this type of injury must surgically remove it within a few hours. Time becomes critical as tissue damage progresses rapidly. The longer you delay getting professional medical attention, the more damage can occur. Although fluid injection accidents are rare, the resulting injury has on occasion required the amputation of a finger, a hand or in some cases the entire limb. The longer the delay in getting professional medical aid, the further up the limb the tissue damage can spread. An injury of this type can become very serious or even fatal if not dealt with promptly and properly.
WARNING
Diesel fuel or hydraulic fluid under pressure can penetrate the skin and could result in death or serious injury. If any fluid is injected under the skin, a medical doctor familiar with the treatment of this type of injury must surgically remove it within a few hours. In the event of any suspected fluid injection injury • Report the injury to your supervisor immediately. • Seek professional medical attention immediately.
As always the best defence against suffering the effects of fluid injection is to prevent the accident from occurring in the first place.
When searching for possible fluid leaks
• Never search for leaks with your bare hands.
Always wear thick protective gloves. • Be sure to wear safety goggles for eye protection. • Keep all body parts well away from the area being investigated for leaks. • Use the end of a long piece of wood to move hoses or other obstacles.
• Place the end of a long piece of wood in the suspected path of any fluid stream. Never use any part of your body. • Recognize that the source of the leak and the fluid streaming from it may be very small and not easily visible. You may only be able to see the fluid that accumulates as a result of the fluid stream.
When performing any service work
• Stop the engine and relieve all diesel fuel or hydraulic pressure before disconnecting any lines or otherwise working on the system. • Never grab any hydraulic or diesel fuel connectors or hoses when they are subjected to pressure. • Always ensure that hoses are rated for the pressures to which they will be subjected. • Never use any hoses that you suspect could be defective.
