chain is correctly tensioned if it can be lifted
around 3-4 mm in the middle of the cutter rail (Fig.
9).
앬 Tighten the fixing screw of the chain wheel cover
(Fig. 7).
Danger! All of the chain links must lie properly in
the guide groove of the cutter rail.
Notes on tensioning the chain:
The saw chain must be properly tensioned to ensure
safe operation. You can tell that the chain tension is
perfect if the saw chain can be lifted by around 3-4
mm in the middle of the cutter rail. As the saw chain
heats up during cutting and thus changes in length,
please check the chain tension every 10 minutes and
adjust it again as required. This applies in particular to
new saw chains. When you have finished working
slacken the chain again, as the chain will shorten
when it cools down. This will prevent the chain from
being damaged.
4.3 Saw chain lubrication
Warning! Always disconnect the mains plug before
performing any checks or adjustments. Always wear
protective gloves when working on the chainsaw to
protect yourself against injury.
Notice: Never operate the chain if it is not lubricated
with saw chain oil. Use of the chainsaw without saw
chain oil or if the oil level is below the “min” mark (Fig.
10/ Item B) will damage the chainsaw.
Notice: Be aware of the temperature conditions:
different lubricants with completely different
viscosities are required at different ambient
temperatures. At lower temperatures you will need low
viscosity oils in order to achieve a sufficient
lubricating film. However, if the same low viscosity oil
is used during the summer it will become even thinner
due to the ambient temperatures alone, and as a
result the lubricating film could break down, causing
the chain to overheat and become damaged. In
addition, the chain oil would burn and produce
unnecessary pollutants.
Filling the oil tank:
앬 Place the chainsaw on a flat surface.
앬 Clean the area around the oil tank cover (Fig.
10/Item A) and then clean the oil tank cover.
앬 Fill the tank with saw chain oil. In the process,
make sure that no dirt enters the tank, as this
could cause the oil nozzle to become blocked.
앬 Close the oil tank cover.
5. Operation
5.1 Connecting to the mains supply
앬 Connect the power cable to a suitable extension
cable. Make sure that the extension cable is
designed for the power rating of the chainsaw.
앬 Secure the extension cable as shown in Fig. 12 to
protect it against pulling forces and accidental
disconnection.
앬 Connect the extension cable to a professionally
installed safety mains outlet with ground contact.
We recommend using a cable with a bright and highly
visible color, e.g. red or yellow. This will reduce the
risk of accidentally damaging it with the chainsaw.
5.2 Switching on/off
Switching on
앬 Hold the chainsaw by the handles with both
hands as shown in Fig. 13 (thumbs under the
handles).
앬 Press and hold the safety lock-off (Fig. 1/Item 5).
앬 Switch on the chainsaw at the ON/OFF switch.
You can then release the safety lock-off.
Switching off
Release the ON/OFF switch (Fig. 1/Item 6).
The integrated brake will bring the running chainsaw
to a standstill within a very short space of time.
Always disconnect the mains plug when you stop
working, even if it is only for a short time.
Warning! Always carry the saw by the front handle. If
the saw is plugged in and you carry it by the rear
handle (which is where the switches are located),
then there is a risk that you could accidentally press
the safety lock-off and the ON/OFF switch at the
same time, and the chainsaw could inadvertently start
up.
5.3 Safety devices – motor brake
The motor brakes the saw chain as soon as the
ON/OFF switch (Fig. 1/Item 6) is released or the
power supply is interrupted. This significantly reduces
the risk of injury that would otherwise be present if the
chain continued to run after being switched off or
disconnected.
Chain brake
The chain brake is a safety mechanism which is
triggered via the front hand guard (Fig. 1/Item 2). If
kickback causes the chainsaw to suddenly jerk back
then the chain brake trips and stops the saw chain in
less than 0.1 seconds. You must check the operation
of the chain brake on a regular basis. To do this, fold
