c) Felling Back Cut
Make the felling back cut at least 2 inches (50 mm) higher
than the horizontal notching cut. 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 fall-
ing 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.
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 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.
When the log is supported along its entire length, it is cut
from the top (over-buck).
When the log is supported on one end, cut 1/3 the di-
ameter from the underside (underbuck). Then make the
finished cut by overbucking to meet the first cut.
When the log is supported on both ends, 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. 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 before you move
the chain saw. Always stop the motor before moving from
tree to tree.
Maintenance and Servicing
Always withdraw the plug when carrying out mainte-
nance and servicing.
In the case of technical problems
• The machine does not start up: Check whether the
current socket is live. Check whether the power cable
is undamaged. If neither case applies, take the chain
saw to a specialised workshop or the works after-sales
service.
• Chain does not run: Check position of handguard.
Chain only runs if handguard brake is released.
• Sparks fly at the motor: Motor or carbon brushes
damaged. Take the chain saw to a specialised work-
shop or the works after-sales service.
• Oil does not flow: Check the oil level. Clean the oil
flow openings in the bar (see also the corresponding
hints of "Maintenance and servicing). If this is not suc-
cessful, take the chain saw to a specialised work-shop
or the works after-sales service.
Attention: Any maintenance or repair work going
beyond that described in these Operating Instruc-
tions may only be carried out by authorised per-
sons or the works after-sales service.
Attention: If the power supply lead of this device
shows any defects, the lead must be replaced by
an authorized repair shop only or through the
manufacturer's own service personnel, as this
work requires special tools.

Waste disposal and environmental protection
If your chain saw should become useless somewhere in
the future or you do not need it any longer, do not dispose
of the device together with your domestic refuse, but dis-
pose of it in an environmentally friendly manner. Please
dispose of the device itself at an according collecing/
