that the cover cannot come loose during saw operation. A
loose cover can cause a loose - dangerous - chain.
(Fig. 6)
CAUTION:
When breaking in a new chain, adjust the tension often,
since it tends to “stretch”.
Switch action
To start the tool, simply pull the trigger. Release the
trigger to stop.
(Fig. 7)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the “OFF”
position when released.
Lubrication
Friction from running the saw at high speed causes
considerable heat-up of the chain. Unless the chain is
tensioned properly and there is sufficient lubrication, the
performance and life of the tool will be adversely affected.
By depressing the oil button in front of the grip, you can
lubricate the guide bar. Switch on the saw, then press the
button 4 or 5 times. Let the oil get around the bar groove
and penetrate before you start cutting. Oil the saw with 5 -
6 presses of the button for every 2 - 3 minutes of
continuous cutting.
Depress the oil button after the button returns to the
original position completely.
(Fig. 8)
Be sure there is enough oil in the oil tank before
operation. There is an oil tank inspection window on the
side opposite the chain cover. Replenish with oil if the
level is low.
(Fig. 9)
To replenish the oil, take off the cap on the tank and fill
with the oil supply.
(Fig. 10)
CAUTION:
Turbine oil #200 or machine oil is recommended. A
special oil or one of high viscosity is neither needed nor
advisable, since the aim is to lubricate the chain and the
guide bar. Do not use dirty oil nor volatile oil.
Cutting operation
Turn the tool on and allow the chain to reach full speed
before it contacts the wood. Be sure the chain is
adequately lubricated.
Use the spike as a pivot point and ease the tool into the
wood, rocking it in gently. Do not force the guide bar in.
Whenever heavy work is prolonged, the overload
protector will cut out to stop the motor.
(Fig. 11)
CAUTION:
If you notice that the guide bar is too hot to touch, stop
operation and let the tool cool off. Check the chain
tension. Make sure the oil is feeding properly.
Holding the chain saw
Always grip each handle with the thumb and fingers
encircling the handle as shown in
Fig. 12 .
Using the chain saw
Always be sure of your footing and hold the chain saw
firmly with both hands while the motor is running.
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 shown in
Fig. 13 .
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.
Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular
to the direction of fall as shown in
Fig. 14 . 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.
Felling back cut
Make the felling back cut at least 2 inches (50.8 mm)
higher than the horizontal notching cut as shown in
Fig. 14 . 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. If there is any chance that the tree may not
fall in the desired direction or it may rock back and bind
the saw chain, stop cutting before the felling back cut is
complete and use wedges of wood, plastic or aluminum to
open the cut and drop the tree along the desired line of
fall. When the tree begins to fall remove the chain saw
from the cut, stop the motor, put the chain saw down, then
use the retreat path planned. Be alert for overhead limbs
falling and watch your footing.
Limbing a tree
Limbing is removing the branches from a fallen tree.
When limbing, leave larger lower limbs to support the log
off the ground. Remove the small limbs in one cut as
shown in
Fig. 15 . Branches under tension should be cut
from the bottom up to avoid binding the chain saw.
Bucking a log
Bucking is cutting a log into lengths. It is important to
make sure your footing is firm and your weight is evenly
distributed on both feet. When possible, the log should be
raised and supported by the use of limbs, logs or chocks.
Follow the simple directions for easy cutting.
