To release the chain brake, pull the hand guard back towards the operator until
a noticeable click is heard.
- The release of the chain brake can also be felt when the chain brake is moved
to the “OFF” position.
To test the chain brake function:
1. Hold the saw firmly by the handles and switch on the motor. The chain should
rotate at this speed.
2. Push the chain brake forward until it is engaged while holding the saw firmly
on the ground. The chain should stop immediately.
Cutting
We suggest that you should cut utilizing the bottom of the bar; this way of
operating diminishes the probability of injuring. Be careful when cutting with the
top of the bar.
1) Holding the Chain Saw
Always grip each handle with the thumb and fingers encircling the handle
as illustrated in following fig. If a manual oiler control is provided additional
or modified instructions regarding its use shall be provided.
2) Using the Chain Saw
Always be sure of your footing and hold the chain saw firmly with both
hands while the motor is running.
3) Felling a Tree
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 as illustrated in following figure.
Before felling is started, consider the natural lean of the tree, the location
of larger branches and the wind direction to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples, and wire from the tree
where felling cuts are to be made.
4) Notching Undercut – Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of fall as illustrated in following figure. Make
the lower horizontal notching cut first. This will help to avoid pinching of
either the saw chain or the guide bar when the second notch is being made.
5) Felling Back Cut – Make the felling back cut at least 2 inches (50.8 mm)
higher than the horizontal notching cut as illustrated in following figure.
Keep the felling back cut parallel to the horizontal notching cut. Make the
felling back cut so enough wood is left to act as a hinge. The hinge wood
keeps the tree from twisting and falling in the wrong direction. Do not cut
through the hinge.
As the felling cut gets close to the hinge the tree should begin to fall.
