• Operate the product only at reasonable hours – not early in the morning or late at night 

when people might be disturbed. 
• Avoid using the product in bad weather conditions, especially when there is a risk of 

lightning. Do not operate the product in poor lighting. The operator requires a clear view 

of the work area to identify potential hazards. 
• Operating similar tools nearby increases both the risk of hearing injury and the potential 

for other persons to enter your work area. 
• Keep firm footing and balance. 
• Do not overreach. Overreaching can result in loss of balance. Always be sure of the 

footing on slopes. 
• Walk, never run. Keep all parts of your body away from any moving part. 
• Never run the product without the proper equipment attached. 
• Do not modify the product in any way or use parts and accessories that are not 

recommended by the manufacturer.

If the product is dropped, suffers heavy impact or begins to 

vibrate abnormally, immediately stop the product and 

inspect for damage or identify the cause of the vibration. 

Any damage should be properly repaired or replace by an 

authorized service center.

• To reduce the risk of injury associated with contacting rotating parts, always stop the 

machine and make sure all moving parts have stopped: 

  - before cleaning or clearing a blockage 

  - when leaving the product unattended 

  - before installing or removing attachments 

  - before checking, maintaining or working on the product 

  - if the machine starts to vibrate abnormally (inspect immediately)

4.6 CUTTING TIPS

Kickback : Illustration  4.2

Reactive forces may occur any time the chain is rotating. Reactive forces can cause serious personal 

injury. The powerful force used to cut wood can be reversed and work against the operator. If the rotating 

saw chain is suddenly  and significantly slowed or stopped by contact with any solid abject such as a log 

or branch or is pinched, the reactive forces may occur instantly. These reactive forces may result in loss of 

control, which, in turn, may cause serious or fatal injury. An understanding of the causes of these reactive 

forces may help you avoid the element of surprise and loss of control. Surprise contributes to accidents.

Rotational kickback can happen when the upper tip of the guide bar contacts an abject while the chain 

is moving. This can cause the chain to dig into the abject and momentarily stop moving. The guide bar is 

then kicked up and back toward the operator in a lightning-fast reverse reaction. 

Linear kickback can happen when the wood on either side of a cut closes in and pinches the moving saw
