SAFETY

 

PRECAUTIONS

 

FOR

 

CHAINSAW

 

USERS

 

Bounce can occur when the nose or tip of the guide bar touches an object, or when 
the wood comes in and pinches the chain at the cut. 
Contact at the tip in some cases can cause quick reverse action, flipping the bar 
toward the operator. Cutting the chain saw along the top of the guide bar can 
quickly propel the guide bar towards the operator. 
Any of these reactions can cause loss of control of the saw which can result in serious 

injury. 
 

Do not rely exclusively on the safety devices built into your saw. As a chain saw 
user, there are several steps you need to take to keep your cutting jobs free from 
accident or injury. Check your safety at all times. 

 

(1) 

With a basic understanding of rebound you can reduce or eliminate the element of 

surprise. Sudden surprise contributes to accidents.  

(2) 

Maintain a good grip on the saw with both hands, the right hand on the rear 

handle and the left hand on the front handle, when the engine is running. Use a firm 
grip with your thumbs and fingers around the chain saw handles. A firm grip will 
help reduce kickback and maintain control of the saw. Don't let her go. 

(3) 

Make sure the area in which you cut is clear of obstructions. Do not allow the 

nose of the guide bar to touch a log, branch, or any other obstruction that could be 
struck while operating the saw. 
Cutting at high engine speeds. 
Do not extend or cut above shoulder height. 

(4) 

Follow the manufacturer's sharpening and maintenance instructions for the saw 

chain. 

(5) 

Use only replacement bars and chains specified by the manufacturer or its 

equivalent.
