STOP

Starting the engine

Do not start the chain saw until after it is completely as-

sembled and checked!

Move at least meters / 0 feet away from the place where the

chain saw was fuelled.

Make sure you have a secure footing, and place the saw on

the ground in such a way that the guide bar and chain are not

near anything.

Actuate the chain brake (block it).

Hold the front handle firmly with one hand and press the saw

against the ground.

Hold the down rear handguard with your right foot as shown.
Note: The Featherlight-Start System lets you start the saw

without effort. Go through the starting procedure smoothly and

evenly.

Cold starting:

Prime the fuel pump (5) by pressing it several times until you

can see fuel in the pump.
Move the combination switch (1) up (choke position). This also

actuates the half-throttle lock.
Pull the starter handle (2) smoothly and evenly.
CAUTION: Do not pull the starter cable more than about 20”

(50cm) out, and let it back in slowly by hand.
Repeat the starting procedure twice.
Move the combination switch (1) to the central “ON” position.

Pull the starter handle smoothly and evenly again. As soon as

the engine is running, grasp the rear handle (the safety lock

button (3) is actuated by the palm of the hand) and press the

throttle trigger (4).
CAUTION: The engine must be put in idle immediately after

starting. If this is not done, the clutch can be damaged.
Now disengage the chain brake.

Warm starting:

As described above for cold starting, but before starting push

the combination switch (1) up (Choke position) and
then right away back to the middle “ON” position. This is only

to engage the half-throttle lock. If the engine doesn’t start after

2 or pulls, repeat the entire starting procedure as described

for cold starting.
NOTE: If the engine was switched off only for a short time, the

saw can be started without using the combination switch.
Important: If the fuel tank has been completely emptied and the

engine has stopped due to lack of fuel prime the fuel pump (5) by

pressing it several times until you can see fuel in the pump.

Stopping the engine

Depress the combination switch (1).
NOTE: After being pressed down, the combination switch will

revert to the ON position again. The engine is switched off, but can

be turned on again without moving the combination switch.
IMPORTANT: To cut off the ignition current, push the combina-

tion switch all the way down past the resistance point to the

safety position ( ).
