The following function check should be carried out at
regular intervals. Push front hand guard 5 forward
(position
) and start the chain saw. The chain must
not start. To deactivate the kickback brake, release
On/Off switch 2 and pull hand guard 5 backwards
(position
).
Cutting
Before Cutting
Before and periodically during cutting check as follows:
– Is the chain saw in a fail-safe condition?
Is the oil reservoir filled? Check oil level
B
gauge 26 prior to starting and regularly during op-
eration. Refill oil when oil level is low. The oil tank
filling will last approx. 15 minutes, depending on
sawing intensity and stops.
– Is the chain tension in order and is the chain
sharp? Check chain tension every 10 minutes
during operation. Upon initial operation, new
chains can lengthen considerably. The condition
of the chain influences the cutting performance.
Only a sharp chain protects from overload.
– Is the kickback brake deactivated and its function
ensured?
– Are you wearing the necessary protective equip-
ment? Wear safety glasses and hearing protec-
tion. Further protective equipment for head, hand,
legs and feet is recommend. Adequate protective
clothing will reduce personal injury by flying de-
bris or accidental contact with saw chain.
Kickback
D
Kickback is the sudden backward/upward motion of
the chain saw, occuring 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 chainsaw reacts unpred-
icably and can cause severe injuries to the operator
or bystanders.
Particular attention must be given when sawing
sidewards, slanted or during length cuts, as the grip-
ping teeth 11 usually can not 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.
– Never saw above shoulder height.
– Never work with the tip of the chain bar.
– Always the hold chain saw firmly with both hands.
– Always use a Bosch low-kickback chain.
– Apply the metal gripping teeth 11 for leverage.
– Ensure correct chain tension.

General Behavior
Always hold the chain saw firmly with both
D
hands. Front grip with the left hand and rear grip with
the right hand. Fully grip both handles at all times
during operation. Never operate chain saw using
only one hand. Ensure power cord is located to the
rear, away from the chain and wood and so pos-
tioned that it will not be caught on branches or the
like during cutting.
Use the chain saw only with secure footing. Hold
E
the chain saw at the right-hand side of your body.
The chain must be running at full speed before it
F
makes contact with the wood. Use the metal gripping
teeth 11 to secure the saw onto the wood before
starting to cut. Use the gripping teeth as a leverage
point "X" while cutting.
Reset the gripping teeth at a lower point when saw-
ing thicker logs by pulling the chain saw slightly
backwards until the gripping teeth release, and repo-
sition at lower level to continue sawing. Do not re-
move the saw completely from the wood.
Do not force the chain while cutting, let the chain do
the work, using the gripping teeth 11 to apply mini-
mal leverage pressure.
Do not operate the chain saw with arms fully ex-
G
tended or attempt to saw areas which are difficult to
reach, or on a ladder. Never use the chain saw
above shoulder height.
Sawing is optimized when the chain speed remains
steady during cutting.
Beware when reaching the end of the cut. The
weight of the saw may change unexpectedly as it
cuts free from the wood. Accidents can occur to the
legs and feet.
Always remove the saw from a wood cut while the
saw is running.
Cutting Logs
Observe the following safety instructions:
Support logs so that the face sides at the cut
E
H
do not close in against each other, which would re-
sult in the chain being jammed or pinched.
Position and set short logs safely prior to sawing.
Saw only wood or wooden objects. When sawing, al-
ways take care to avoid hitting stones, nails, etc., as
these could be thrown up or cause damage to the
chain or serious injury to the operator or bystanders.
Keep a running 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 care, as lever-
age with the gripping teeth 11 is not possible. Saw at
a flat angle to avoid kickback.
