released and reinsert the chain saw at a lower level to
continue sawing. Do not pull the chain saw completely out
of the cut.
– Keep the chain saw running throughout the entire cut,
maintaining a steady speed.
– Do not force the saw chain while cutting, let the chain do
the work.
– Always remove the chain saw from the wood cut while the
saw chain is running.
– 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.
– Release the On/Off switch as soon as the cut is complete
so that the chain comes to a standstill and position the
kickback brake (5) correctly in position O (see figure E1).
Kickback (see figure G)
With a basic understanding of kickback, you can reduce or
eliminate the possibility of kickback forces. Suddenly occur-
ring kickbacks can lead to accidents.
Always ensure that you are standing on the ground steadily
and keep your balance.
Kickback is the sudden backward/upward motion of the
chain saw, occurring 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 chain saw reacts unpredictable
and can cause heavy injuries to the operator or bystanders.
Pay particular attention when sawing in lateral and diagonal
directions and when making longitudinal cuts. The metal
spiked bumper (9) cannot normally be used for these cuts.
Observe the following precautions to minimise kickback:
– Always ensure that the chain saw is handled correctly.
– Maintain a firm grip and stiff left arm to keep control of
the chain saw if a kickback occurs.
– Ensure that the area in which you are cutting is free of
obstacles. Ensure that the nose of the chain bar does not
come into contact with a tree trunk, branch, fence or
other obstacle that you could hit while working with the
saw.
Note: Kickback may occur if the tip of the chain bar comes
into contact with an obstacle.
Troubleshooting
The following chart lists problem symptoms, possible causes and corrective action, if your power tool does not operate prop-
erly. If these do not identify and correct the problem, contact your service agent.
Warning: Switch off and remove the battery prior to any troubleshooting.
Problem
Possible Cause
Chain saw fails to oper-
Kickback brake is activated
ate
Battery discharged
Battery not fully connected
Motor protector has activated
Battery too hot/cold
Bosch Power Tools
– Always cut at the full speed of the chain saw. Press the
On/Off switch (2) all the way down and maintain a con-
stant cutting speed.
– Only use the recommended replacement chain bars and
low-kickback chains by Bosch.
Kickback brake
The kickback brake is a safety mechanism that is activated
by the wrist via the lever for activating the kickback brake
(5) when kickback occurs. The saw chain stops immediately.
This reduces the risk of injury from kickback.
Regularly test to ensure the kickback brake is working:
– Hold the chain saw firmly with both hands.
– Switch on the chain saw.
– When the saw chain is rotating, push the lever forwards
with your wrist to activate the kickback brake (5). Do not
use the chain saw if the saw chain does not stop immedi-
ately during this test.
Note: Do not stop the chain saw during normal use by delib-
erately activating the lever for the kickback brake (5).
Cutting Logs (see figure H)
– Always secure the logs before cutting.
– Always cut the logs beyond the secured points to prevent
the log from closing in and causing the chain to get
jammed.
– Never allow the saw chain to make contact with the
ground or cutting equipment.
– Be careful not to trip over tree stumps, branches, roots,
etc.
Cutting Wood under Tension (see figure I)
– 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.
Limbing a Branch or Tree (see figure J)
– Limbing is removing the small branches from a fallen tree
or large branch.
– Leave larger lower limbs to support the log off the ground.
– Remove the smaller limbs in one cut.
Corrective Measure
see figure E1
Recharge battery; also see "Battery Charging"
Ensure both locking levels are engaged
Allow motor to cool
Allow to cool/warm
