6.5 Gather up guide bar and chain. please refer to 5.2
WARNING: For you safety and storage, please gather up cutting guard after each operation.
7. CUTTING
7.1 Basic cutting
WARNING: Always be sure of footing and hold the chain saw firmly with both hands while the
motor is running.
1. Assume the proper cutting grip and stance in front of the wood with the saw off. Press the trigger
lock-out and squeeze the switch trigger. Let the chain reach full speed before beginning the cut.
2. Begin cutting by lightly pressing the guide bar against the wood. Use only light pressure, letting
the saw do the work.
3. Maintain a steady speed throughout the cut, releasing pressure just before the end of the cut.
7.2 Pruning
When pruning, make sure all bystanders or helpers are a safe distance from falling branches and
are not directly in front of or behind the saw operator. Secure any branches that might pose a
hazard. Use the proper auxiliary equipment. Maintain good footing, hold the saw firmly with both
hands, and do not overreach.
With the saw at full speed, bring the bottom of the guide bar into contact with the branch to be cut.
Continue cutting using light pressure. For larger branches, first make a shallow undercut on the
bottom of the branch and then finish the cut from the top. Cutting a large branch completely from
the top could cause splintering. A complete cut from the bottom can cause the branch to pinch the
bar.
7.3 Felling a tree (Fig.12)
When bucking and felling operations are being performed by two or more persons, at the same
time, the felling operation should be separated from the bucking operation by a distance of at least
twice the height of the tree being felled. Trees should not be felled in a manner that would endanger
any person, strike any utility line or cause any property damage. If the tree does make contact with
any utility line, the utility company should be notified immediately.
The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or
slide downhill after it is felled. A retreat path should be planned and cleared as necessary before
cuts are started. The retreat path should extend back and diagonally to the rear of the expected line
of fall.
