Equipment Safety

Chainsaws are high-speed, fast-cutting equipment with exposed blades that can cause serious or fatal injury if not used correctly or without taking proper safety precautions. It is

extremely important that you read and fully understand the information in this section and all other safety warnings / recommendations and usage instructions before using the equipment.

Operator

• If you are untrained in the use of a chainsaw, it is highly recommended that you be trained/instructed by a suitably qualified or experienced chainsaw user before using the machine.

• Fully understand how to safely operate the machine and the sawing process to avoid "kick-back". See Chainsaw Operation.

• You must be in good physical condition to use a chainsaw. NEVER operate the machine when tired, or under the influence of any substance (medication, alcohol, drugs etc) that may impair your judgement, alertness, physical strength, vision or dexterity.

• Maintain sure-footing and balance always when using or handling the chainsaw and have full awareness of your surroundings and any possible hazards.

• Prolonged chainsaw use may lead to health complications, such as carpal tunnel syndrome, due to vibration. To help reduce the possibility of such conditions, wear gloves, take breaks frequently, keep fingers and hands warm, and maintain the equipment for optimal operation and minimal vibration. It is recommended to seek medical advice if you feel numbness or burning sensations in fingers/hands.

Clothing and Protective Equipment – All Operators and Assistants

• Wear approved safety goggles, or safety glasses with adequate top and side protection. In addition to eye protection, wearing a full-face shield is highly recommended.

• Wear suitable hearing protection.

• Wear an approved safety hard-hat.

• Wear heavy-duty, non-slip leather or protective gloves.

• Wear approved heavy-duty safety boots, with steel toe-caps and non-slip soles.

• Wear suitable overalls or work clothing that fits snugly, but does not restrict movement. It is highly

recommended to provide additional cut protection to legs, such as Kevlar chaps. Avoid loose fitting clothing, scarves, jewellery etc and keep long hair contained to avoid getting caught or pulled by the chainsaw or by tree branches etc.

Work Area Safety

• Use EXTREME CAUTION to avoid power lines – contact can be fatal. Do NOT cut branches touching power lines or that may fall onto power lines when cut.

• To operate the chainsaw at height it is highly recommended to use a "scissor lift" or "cherry picker" and ensure that the work platform is completely stable. Do NOT use ladders, ropes or tree branches.

• Ensure that any person other than the operator and any assistants is kept a minimum 25m (75') away from where the equipment is being used or where there is any possibility of falling branches, trees etc. Be aware of any property that may be affected by falling branches, trees etc.

• Be aware of fire risks resulting from machine use. Ensure that the machine exhaust and spark arrestor (if equipped) is well maintained and that engine is tuned correctly.

• Refuel outdoors only. Avoid fuel spillage. Start the machine at least 3m (10') away from the fuelling location.

Petrol Powered Chainsaws

Operational Safety

• Do NOT use the machine if the throttle or any safety guard or mechanism is not installed or is not operating correctly – have the machine inspected and repaired at an authorised service centre before using it again.

• Fully understand how to safely operate the machine and the sawing process to avoid "kick-back". See Chainsaw Operation.

• Always hold the machine firmly with both hands during operation. Always use the machine handles.

• Do NOT use a ladder or tree branches as a platform when using the machine at height – always use a

stable, flat platform such as a cherry-picker or scissor-lift.

• Do NOT use the equipment for purposes it is not designed for, such as wood chipping.

• Before cutting any branch, limb, pruning or cross-cutting, ensure that none of the materials to be cut is

under tension that may be released unexpectedly during cutting.

• Tree felling should be performed by trained and experienced personnel only. If in any doubt, seek assistance and advice.

Transportation Safety

• Always STOP the engine and activate the chain-brake before putting the machine down, transporting or working on it (refuelling, adjusting etc).

• Fit the blade sheath whenever transporting or storing the machine.

• When walking with the machine, ensure the engine is OFF and the

chain brake is engaged, and the blade sheath is installed. Hold the machine by the upper handle, with the blade pointing backwards and the exhaust away from the body.

• When transporting the machine in a vehicle, ensure the engine is OFF and the chain brake is engaged, and the blade sheath is installed. Secure the machine in an upright position to prevent tip-over, machine damage or fuel spills.
