Sawing

 

 

Before proceeding to your job, read "For 
Safe Operation" section it is recommended to first 
practice sawing easy logs. This also helps you get 
accustomed to your unit. 

Always  follow  all  the  safety  regulations  which  can 
restrict the use of the machine.

 

Always follow the safety regulations. The chain saw 
must only be used for cutting wood. It is forbidden 
to cut other types of material. Vibrations and 
kickback vary with different materials and the 
requirements of the safety regulations would not be 
respected. Do not use the chain saw as a lever for 
lifting, moving or splitting objects. Do not lock it over 
fixed stands. It is forbidden to hitch tools or 
applications to the P.T.O. that are not specified by 
the manufacturer. 
It is not necessary to force the saw into the cut. 
Apply only light pressure while running the engine at 
full throttle. 
It is recommended that daily inspection before use 
and after dropping or other impacts to identify 
significant damage or defects. 
Racing the engine with the chain seized in a cutaway 
can damage the clutch system. When the saw chain 
is caught in the cut, do not attempt to pull it out by 
force, but use a wedge or a lever to open the cut. 

■

 

Guard against kickback 

This saw is also equipped with a chain brake that will 
stop the chain in the event of kickback if operating 
properly. You must check the chain
