GENERAL SAFETY RULES

WARNING:

The warnings, labels and instructions found in this section of the operator’s manual are for your safety. Failure to follow all instructions may result in serious personal injury.

Safe operation of this tool requires that you read and understand this operator’s manual and all labels affixed to the tool. Safety is a combination of using common sense, staying alert, and knowing how your saw works.

READ ALL INSTRUCTIONS

KNOW YOUR TOOL. Read the operator’s manual carefully. Learn the saw’s applications and limitations as well as the specific potential hazards related to this tool.

CHAINSAWS are designed for cutting wood only.

KICK-BACK MAY OCCUR WHEN THE NOSE OR TIP OF THE GUIDE BAR touches an object or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious personal injury. DO NOT rely exclusively upon the safety devices built into your saw. As a chainsaw user, you should take several steps to keep cutting jobs free from accident or injury.

1.With a basic understanding of kick-back, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

2.Keep a good firm grip on the saw with both hands when the engine is running. Place your right hand on the rear handle and your left hand on the front handle, with thumbs and fingers encircling the chainsaw handles. A firm grip together with a stiff left arm will help maintain control of the saw if kick-back occurs.

3.Make sure the area in which you are cutting is free from obstructions. DO NOT let the nose of the guide bar contact a log, branch, fence or any other obstruction which could be hit while you are operating the saw.

4.Cut at high engine speeds. Always cut with the engine running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed.

5.Do not overreach or cut above shoulder height.

6.Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.

7.Only use replacement bars and chains specified by the manufacturer or the equivalent.

DO NOT OPERATE A CHAINSAW WITH ONE HAND. Serious injury to the operator, helpers and/or bystanders may result from one-handed operation. A chainsaw is intended for two-handed use.

DO NOT OPERATE A CHAINSAW WHEN YOU ARE FATIGUED. Never operate a chainsaw when you are tired or under the influence of medication, drugs or alcohol.

USE SAFETY FOOTWEAR. Wear snug-fitting clothing, protective gloves and eye, hearing and head protection devices.

DO NOT STAND ON ANY UNSTABLE SURFACE while using your chainsaw. This includes ladders, scaffolding, trees etc.

USE CAUTION WHEN HANDLING FUEL. Move the chainsaw at least 9 m (30 feet) from the refuelling point before starting the engine.

DO NOT ALLOW OTHER PERSONS to be near the chainsaw when starting or cutting with the chainsaw. Keep bystanders and animals out of the work area.

DO NOT START CUTTING until you have a clear work area, secure footing and a planned retreat path from the falling tree.
