5. Grasp the rear handle with your right hand. Thumb
and fingers should encircle the handle;.
6. Press the safety lock-off button (3) with your right
thumb, then fully press the switch trigger (4) with
your index finger and hold it in this position.
7. While the motor is running, activate the chain brake
lever by rolling your left hand forward against the
chain brake lever.
(Fig. 9b)
8. Chain and motor should stop immediately.
9. If the chain brake functions normally, switch off the
motor and return the chain brake in disengaged po-
sition.
NOTE:
The motor will not start if the chain brake is in the
engaged position.
CAUTION!
The chain brake should not be used for start-
ing and stopping the saw during normal operation.

KICKBACK
(Fig. 2a)
Kickback is the sudden backward/upward motion of the
chain saw, occurring when the chain (at the tip of the
chain bar) comes in contact with a log or wood, or when
the chain becomes jammed.
When kickback occurs the chain saw reacts unpredict-
ably and can cause severe injuries to the operator or
bystanders.
Particular attention must be given when sawing side
-
ward, slanted or during length cuts, as the spiked bump
-
er (14) usually cannot be applied.
To avoid kickback:
- Saw with the chain bar at a flat angle.
- Never work with a loose, widely stretched or the
heavily worn out chain.
- Ensure chain is sharpened correctly prior to opera-
tion.
- Never saw above shoulder height.
- Never work with the tip of the chain bar.
- Always hold the chain saw firmly with both hands.
- Always use a low-kickback chain.
- Apply the spiked bumper for leverage.
- Ensure correct chain tensioning.
GENERAL BEHAVIOR
Always hold the chain saw firmly with both hands, front
grip with the left hand and rear grip with the right hand.
Fully grip both handles at all times during operation. Nev
-
er operate chain saw using only one hand.
Ensure power cord is located to the rear, away from
the chain and wood and so positioned that it will not be
caught on branches or the like during cutting.
Operate the chain saw only with secure footing. Hold the
chain saw at the right-hand side of your body.
(Fig.10)
The chain must be running at full speed before it makes
contact with the wood. Use the spiked bumper to secure
the saw onto the wood before starting to cut. Use the
spiked bumper (14) as a leverage point while cutting.
(Fig.11a)
Reset the spiked bumper at a lower point when sawing
thicker logs by pulling the chain saw slightly backwards
until the spiked bumper releases, and repositions at
lower level to continue sawing. Do not remove the saw
completely from the wood.
Do not force the chain while cutting, let the chain do the
work, using the spiked bumper to apply minimal leverage
pressure.
Do not operate the chain saw with arms fully extended
or attempt to saw areas which are difficult to reach, or
on a ladder. Never use the chain saw above shoulder
height.
(Fig.11b)
Optimum results are achieved when the chain speed re
-
mains steady during cutting.
Beware when reaching the end of the cut. The weight of
the saw in your arms may change unexpectedly as it cuts
free from the wood.
Always remove the saw from a wood cut while the saw
is running.
FELLING A TREE
(Fig.12)
WARNING:
Always wear a safety helmet
where there is a risk of falling objects..
WARNING:
The chain saw can only be used
to fell trees smaller in diameter than the usable cutting
length of the chain bar.
WARNING:
Prior to performing the felling cut
always re-check there are no bystanders, animals or
obstacles in the vicinity of the falling tree.
WARNING:
Do not cut down a tree during
high or changing winds or if there is a danger to prop-
erty.
When bucking and felling operations are being per-
formed by two or more persons, at the same time, the
felling operations 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 con-
tact with any utility line, the 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.
An escape path
②
. should be planned and cleared as
necessary before cuts are started. The escape path
should extend back and diagonally to the rear of the ex-
pected line of fall
③
.
Before felling is started, consider the natural lean of the
tree, the location of larger branches and the wind direc
-
tion to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails staples, and wire
from the tree.
Small trees up to 15–18 cm in diameter are usually cut in
