Chainsaw mounting kit
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 described 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 qualied 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.

The cutters should be cleaned and lubricated at regular
intervals in order to ensure best performance at all
times. Remove deposits with a brush and apply a thin 
lm of oil.
Storage
Store the equipment and accessories in a dark and dry
place at above freezing temperature. The ideal storage
temperature is between 5 and 30 °C. Store the electric
tool in its original packaging.
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 positioned
for a cut in the region of the tip of the cutter rail, as the
leverage eff ect is greatest there. It is therefore safest to
position the saw as at 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 cutter
rail.
• Always hold the chainsaw rmly 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 react com-
pletely 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 blowing 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 rm 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 pe-
riod of time then you should remove the chain oil from
the tank. Briey 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 liquids
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 com-
pressed air at low pressure.
• We recommend that you clean the device immediately
each time you have nished 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 incre-
ases the risk of an electric shock.
