Clamping the Chain Bar
– When the chain 10 is tensioned, clamp the chain bar 11 by
turning the locking knob 14 in clockwise direction. Do not
use a tool for this.

Saw-chain Lubrication (see figures A–B)
Note: The chain saw is not supplied filled with oil. It is essen-
tial to fill with oil before use. Operating the chain saw without
chain oil or when the oil level is below the minimum mark will
result in damage to the chain saw.
Chain life and cutting capacity depend on optimum lubrica-
tion. Therefore, the chain is automatically lubricated with
chain oil during operation via the oil outlet 19.
Filling the oil reservoir:
– Set chain saw on any suitable surface with the oil filler cap
4 facing upward.
– Clean area around the oil filler cap 4 with a cloth and un-
screw the cap.
– Do not remove filter insert during filling.
– Add chain saw oil (preferably biodegradable) until
tank/reservoir is full.
– Avoid dirt or debris from entering the oil reservoir. Screw
on oil filler cap 4 again and tighten.
Note: Four small compensation channels allow for pressure
compensation between the oil reservoir and the environment.
For functional reasons, minor amounts of oil can escape here.
Please take care to place down the chain saw with the oil filler
cap 4 facing upward.
Note: It is important to use only chain saw oil (preferably bio-
degradable) to avoid damage to the chain saw. Never use re-
cycled/old oil as doing so will invalidate the warranty.

Dust/Chip Extraction

 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.

Operation

Starting Operation

 Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine.
Switching On and Off
To save energy, only switch the power tool on when using it.
Hold the chain saw as described in section "Working with the
Chain Saw".
To start the machine, first push the lock-off button for the
On/Off switch 2 and then press the On/Off switch 3 and keep
it pressed.
To switch off the machine, release the On/Off switch 3.
Note: For safety reasons, the On/Off switch 3 cannot be
locked; it must remain pressed during the entire operation.
Note: Do not stop chain saw after sawing by actuating the
front hand guard 5 (activating the kickback brake).
Reduced starting current
The electronic reduced starting current limits the power con-
sumption when switching the tool on and enables operation
from a 13 ampere fuse.
Temperature Dependent Overload Protection
In case of overload, e. g., when the saw chain is dull, the mo-
tor can stop due to actuation of the thermal safety switch.
Press the reset button 25 to reset the safety switch. After-
wards, the chain saw must be operated at no-load for approx.
1 minute.
Run-down Brake/Kickback Brake (see figure D)
The chain saw is equipped with two safety features:
The run-down brake stops the saw chain after releasing the
On/Off switch 3.
The kickback brake is a safety mechanism activated through
the front hand guard 5 when kickback occurs. Chain stop re-
sponse time is 0.1 seconds.
The following function check should be carried out at regular
intervals. Push the front hand guard 5 forward (position )
so that the red dot 26 under the mark 7 becomes visible, and
briefly start the chain saw. The saw chain must not start. To
deactivate the kickback brake again, pull the front hand guard
5 back (position ), so that the red dot 26 under the mark 7
is covered.

Working with the Chain Saw

Before Cutting
Before starting operation and periodically during cutting, car-
ry out the following checks:
– Is the chain saw in a fail-safe condition?
– Is the oil reservoir filled? Check oil level gauge prior to
starting and regularly during operation. Refill oil when oil
level has reached the bottom edge of the viewing glass.
The oil tank filling will last approx. 15 minutes, depending
on sawing intensity and stops.
