– Never work with the tip of the chain.
– Always hold a chain saw firmly with both
hands.
– Always use a Bosch low-kickback saw chain.
– Apply the metal gripping teeth 13 for lever-
age.
– Ensure correct chain tension.
General Behaviour (see figures D – G)
Always hold the chain saw firmly with both
hands. Front handle with the left hand and rear
handle with the right hand. Fully grip both han-
dles with thumb and fingers at all times during
operation. Never operate chain saw using only
one hand. Ensure power cord is located to the
rear, and keep it out of the range of the saw
chain and cutting material; position yourself in
such a manner that the mains cable can not get
caught in branches and twigs.
Use the chain saw only with secure footing. Hold
the chain saw at the right-hand side of your body.
The chain must be running at full speed before
it makes contact with the wood. Use the grip-
ping teeth 13 to support the chain saw on the
wood. Use the gripping teeth as a leverage point
while cutting.
Reset the gripping teeth at a lower point when
sawing thicker logs or tree trunks. For this, pull
the chain saw slightly backwards until the grip-
ping teeth release, and reposition at lower level
to continue sawing. Do not remove the chain
saw completely out of the cut.
Do not force the saw chain while cutting, let the
chain do the work, using the gripping teeth 13 to
apply minimal leverage pressure.
Never operate the chain saw with arms fully ex-
tended. Do not attempt to saw areas which are
difficult to reach, or on a ladder. Never saw
above shoulder height.
Sawing is optimized when the chain speed re-
mains steady during cutting.
Beware when reaching the end of the cut. The
weight of the chain saw changes unexpectedly
as it cuts free from the wood. Danger of injury to
the legs and feet.
Always remove the chain saw from a wood cut
while the saw chain is running.

Cutting Logs (see figures E and H)
When cutting logs, observe the following safety
instructions:
Support logs so that the face sides at the cut do
not close in against each other, which would re-
sult in the chain being jammed.
Position and set short logs safely before sawing.
Saw only wood or wooden objects. When saw-
ing, always take care to avoid hitting stones,
nails, etc., as these could be thrown up, could
cause damage to the chain, or could result in se-
rious injury to the operator or bystanders.
Keep a running chain saw clear of wire fencing
or the ground.
Use of the saw to thin out branches or bushes is
not approved.
Length cuts must be carried out with particular
care, as leverage with the gripping teeth 13 is
not possible. Saw at a flat angle to avoid kick-
back.
When working on a slope, operate above or to
the side of the trunk or laying tree.
Be careful not to trip over tree stumps, branch-
es, roots, etc.
Cutting Wood under Tension (see figure H)
Be extremely careful when sawing wood,
branches or trees under tension. Leave saw
jobs like these to trained professionals.
There is a high risk of accidents.
When sawing logs supported on both ends, start
the cut from above (Y) about one third of the di-
ameter into the log and then finish the cut at the
same spot from below (Z), in order to avoid
splitting of the log or jamming of the saw. Avoid
contact of the saw chain with the ground.
When sawing logs supported on only one end,
start the cut from below (Y) about one third of
the diameter into the log and then finish the cut
at the same spot from above (Z), in order to
avoid splitting of the log or jamming of the saw.
Felling Trees (see figure I)
Always wear hard hat to protect head
against falling branches.
