This will prevent the saw from making jerky move-
ments when you begin a cut. Exerting slight pressure,
guide the saw from the top to the bottom through the
branch.
Sawing off larger and longer branches (Fig. 17):
Carry out a relief cut when working on larger branch-
es. Start by sawing through 1/3 of the branch diam-
eter (a) from the bottom to the top with the top side
of the cutter rail. Then saw towards the fi rst cut (b)
from the top to the bottom with the bottom side of the
cutter rail.
Saw off longer branches in several steps to keep con-
trol over the impact location.
Kick-back!
The term "kickback" describes what happens when
the running chainsaw suddenly kicks upward and
backward. Usually, this is caused by contact between
the tip of the cutter rail and the workpiece or the saw
chain becoming trapped.
In the event of kickback, large forces occur suddenly
and violently. As a result, the chainsaw usually reacts
uncontrollably. This can often result in very serious
injuries to the worker or persons in the vicinity. The
risk of kickback is at its greatest when the saw is posi-
tioned for a cut in the region of the tip of the cutter rail,
as the leverage effect is greatest there. It is therefore
safest to position the saw as flat as possible.
Important!
• Make sure that the chain tension is always correctly
adjusted.
• Only use a chainsaw if it is in perfect working order.
• Only work with a saw chain that has been properly
sharpened in accordance with the instructions.
• Never cut with the upper edge or the tip of the cut-
ter rail.
• Always hold the chainsaw firmly with both hands.
Cutting wood which is under tension
Special care is required when cutting wood which
is under tension. Wood which is under tension from
which it is released by cutting may in some cases re-
act completely unpredictably and uncontrollably. In
the worst case this could result in extremely severe
or even fatal injuries. This type of work must only
be performed by persons who have been specially
trained.
Cleaning and maintenance
Danger!
Remove the battery pack before doing any cleaning
and maintenance work.
Cleaning
• Regularly clean the clamping mechanism by blow-
ing it out with compressed air or cleaning it with a
brush. Do not use tools for cleaning.
• Keep the handles free of grease so that you can
maintain a firm grip.
• Clean the equipment as required with a damp cloth
and, if necessary, mild washing up liquid.
• If the chainsaw is not to be used for an extended
period of time then you should remove the chain oil
from the tank. Briefly immerse the saw chain and
the cutter rail in an oil bath and then wrap them in
oil paper.
• Never immerse the equipment in water or other liq-
uids in order to clean it.
• Use a brush to remove deposits from the safety
guards.
• Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible.
Wipe the equipment with a clean cloth or blow it
with compressed air at low pressure.
• We recommend that you clean the device immedi-
ately each time you have finished using it.
• Clean the equipment regularly with a moist cloth
and some soft soap. Do not use cleaning agents
or solvents; these could attack the plastic parts of
the equipment. Ensure that no water can seep into
the device. The ingress of water into an electric tool
increases the risk of an electric shock.
Maintenance

Replacing the saw chain and cutter rail
The cutter rail needs to be replaced if the guide
groove of the cutter rail is worn; Proceed as de-
scribed in the section "Assembly of the cutter rail and
the saw chain".
Checking the automatic chain lubrication
You should check the operation of the automatic chain
lubrication system on a regular basis in order to guard
against overheating and the associated damage to
the cutter rail and the saw chain. To do this, point the
tip of the cutter rail towards a smooth surface (board,
section of a cut tree) and allow the chainsaw to run.
If an increasing oil trace becomes evident during this
process then the automatic chain lubrication system
is working properly. If no clear oil trace is evident
then please refer to the corresponding instructions in
"Troubleshooting". If the information contained there
still fails to remedy the situation then please contact
our service department or another similarly qualified
workshop.
Important! Do not actually touch the surface with the
tip of the cutter rail when performing this test. Keep a
safe distance (approx. 20 cm).
Sharpening the saw chain
Effective working with the chainsaw is only possible
if the saw chain is in good condition and sharp. This
also reduces the risk of kickback. The saw chain can
be re-sharpened by any dealer. Do not attempt to
sharpen the saw chain yourself unless you have the
necessary special tools and experience.
