When cutting thick branches, first make a shallow cut in the lower part and then finish the
cut from the upper part.
If you can't cut the tree all at once:
Apply slight pressure to the handle and continue to cut the saw, then pull the chainsaw
back slightly and press the spines down slightly, and finally lift the handle to complete
the cut.
Chain saw counter-thrust safety device:
Chain brake
The chainsaw is equipped with a chain brake that stops both the motor and the chain
when a kick occurs. During the backkick, the forward movement of the chain backkick
brake handle causes the chain brake to work as the chain rotates backward. The
inertial forces generated in the fast push back process also cause the chain brake to
act.
Warning
:
Do not modify or attempt to disable chain brakes.
Make sure the chain brake works properly before using the chainsaw. Chain back
kick brake handle should be easy to move back and forth.
To test the operation of the chain brake, perform the following steps :
If you try to cut off a thicker branch completely from the lower part, the branch may clamp
and squeeze the chain in the cut. If you try to cut off the thicker branch completely from
the upper part without making a shallow cut in the lower part, the branch may crack.
