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 affi xed to the tool. Safety is a combination of 
using common sense, staying alert, and knowing how 
your saw works.

  KNOW YOUR TOOL. Read the operator’s manual 

carefully. Learn the saw’s applications and limitations 
as well as the specifi c potential hazards related to this 
tool.

  CHAINSAWS are designed for cutting wood only.

  KICK-BACK MAY OCCUR WHEN THE NOSE OF THE 

GUIDE BAR touches an object or when the wood closes 
in and pinches the saw chain in the cut. The nose of guide 
bar contact in some cases may cause a lightning-fast 
reverse reaction kicking the guide bar up and back toward 
the operator. Pinching the saw chain along the top of the 
guide bar may push the guide bar rapidly back toward 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 your 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 fi rm 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 your 
thumbs and fi ngers encircling the chainsaw handles. A 
fi rm grip together with a stiff left arm will help you maintain 
control of the saw if kick-back occurs.

 

3. Make sure that 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 
that 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 chest height.

 

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

 

7. Use only replacement bars and chains specifi ed by the 
manufacturer or the equivalent.

  DO NOT OPERATE A CHAINSAW WITH ONE HAND.
