7. SAWING
·
It is not necessary to force the saw into the cut. Apply only light pressure while running the
engine at full throttle.
·
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 way.

GUARD AGAINST KICKBACK
This saw is equipped with a chain brake that will stop the chain in the event of kickback if operating properly.
You must check the chain break operation before each usage by running the saw at full throttle for
1-2 seconds and pushing the front hand guard forward. (IMAGE L)
The chain should stop immediately with the engine at full speed. If the chain is slow to stop or does not stop,
replace the brake band and clutch drum before use.
It is extremely important that the chain brake be checked for proper operation before each use and that the
chain be sharp in order to maintain the kickback safety leveled the saw. Removal of the safety devices,
inadequate maintenance, or incorrect replacement of the bar or chain may increase the risk of serious personal injury due to kickback.

FELLING A TREE
a. Decide the felling direction considering the wind, lean of the tree, location of heavy breaches, ease of job after felling and other factors.
b. While cleaning the area around the tree, arrange a good foothold and retreat path.
c. Make a notch cut the one-third of the wood into the tree on the felling side.
d. Make a felling cut from the opposite side of the notch and at a level slightly higher than the bottom of the notch. (IMAGE M)
When you fell a tree, warn all coworkers and neighbors of the danger.
