To do this, pull back the hand protection in the
direction of the handle.

2. Rundown brake

In accordance with the latest regulations, this chain saw is
equipped with a mechanical rundown brake. This brake is
connected to the chain brake and stops the running chain
after the chain saw has been switched off.
It is activated by releasing the ON/OFF switch. The rundown
brake avoids injuries through the coasting of the chain.

3. Safety starting lock

The starting delay that is effective for about 3 sec. after each
switch-off of the chain saw provides for additional safety.
Thus, for your own safety, there is a delay of 3 seconds
before the device can be switched on again after each
time it is switched off.
Only after this phase, the saw may be operated again by
pushing the locking button 15 and subsequently activating the
operating switch 9, as described in the section 'Switching on'.
4. Chain catch bolt (Fig. 7)
This chainsaw is fitted with a chain catch bolt (17). If the
chain breaks when the saw is in operation, the chain bolt
will catch the loose chain end and thus prevent injury to
the operator's hand.
8. Instructions on working properly with the
chain saw
(Fig. 8 - 14)
a) Felling a Tree
When bucking and felling operations are being performed
by two or more persons, at the same time, the felling ope-
ration should be separated from the bucking operation by a
distance of at least twice the height of the tree being felled.
Trees should be felled in a manner that would endanger any
person, strike 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
befor cuts are started. The retreat path should extend back
and diagonally to the rear of the expected line of fall as illus-
trated in Figure 8.
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.
b) Notching Undercut
Make the notch 1/3 the diameter of the tree, perpendi-
cular to the direction of fall as illustrated in 9. Make the
lower horiziontal 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.
c) Felling Back Cut
Make the felling back cut at least 2 inches (50.8 mm) high-
er than the horizontal notching cut as illustrated in Figure 9.
23
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.
d) 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
illustrated in Figure 10. Branches under tension should
be cut from the bottom up to avoid binding the chain saw.
e) Bucking a Log
Bucking is cutting a log into lengths. It is important to make
sure your footing is fim and your weigth 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.
When the log is supported along its entire length as illustrated
in Figure 11, it is cut from the top (over-buck).
When the log is supported on one end, as illustrated in Figure
12, cut 1/3 the diameter from the underside (underbuck). Then
make the finished cut by overbucking to meet the first cut.
When the log is supported on both ends, as illustrated in Figure
13, cut 1/3 of that diameter from the top overbruck. Then make
the finished cut by underbucking to meet the first cut.
When bucking on a slope always stand on the uphill side of
the log, as illustrated in Figure 14. When "cutting through",
to maintain complete control release the cutting pressure
near the end of the cut without relaxing your grip on the
chain saw handles. Don't let the chain contact the ground.
After completing the cut, wait for the saw chain to stop be-
fore you move the chain saw. Always stop the motor before
moving from tree to tree.

9. Maintenance and Servicing

Always withdraw the plug when carrying out
maintenance and servicing.
• Always remove wood shavings and oil from your chain
saw after use. Ensure in particular that the motor ven-
tilation slits for cooling the motor in the housing of the
chain saw is free (danger of overheating).
• If the saw chain is particularly dirty, e.g. in case of gumming
with resin, remove the chain and clean it. Place the chain
for a few hours in a vessel containing chainsaw cleaner.
There-after clean the chain with clear water. If the chain is
not used again immediately, it must be treated with service
spray or a customary anticorrosion-spray.
