10.1 Starting the engine (6) (Fig. 9, 10)
ATTENTION
– Always pull the pull starter out straight.
– Hold the handle of the pull starter firmly when the
pull starter winds back in.
– Do not let the pull starter whip back in. This can re-
sult in damage.

10.1.1

Starting a cold engine

Notes:
With high outside temperatures, it may be necessary to
start the engine without the choke even when the engine
is cold!
As soon as the choke is opened after starting, the product
will begin to shake at half throttle.
1. Before starting, check the fuel and engine oil levels
and ensure that the spark plug connector (16a) is con-
nected to the spark plug (16).
2. Open the fuel tap (12c).
3. Set the on/off switch (15) to the "ON" position.
4. Set the throttle (2) to "half throttle" (= middle position
between "fast" and "slow").
5. Move the choke (12b) to the "Closed" ( ) position.
6. Slowly pull out the pull starter (7) until the first resis-
tance is felt.
7. Now pull the pull starter (7) quickly until the engine
starts.
If the engine does not start, repeat the procedure.
8. Allow the engine (6) to warm up briefly. Then slowly
open the choke (12b) to switch to "Normal operation"
9. Set the throttle (2) to the working position ("fast") and
the product starts to work.
10. Set the throttle (2) to the idle ("slow") position and the
product runs at idle.
10.1.2
(The product stood still for less than 15-20 minutes.)
1. Before starting, check the fuel and engine oil levels
and ensure that the spark plug connector (16a) is con-
nected to the spark plug (16).
2. Open the fuel tap (12c).
3. Set the on/off switch (15) to the "ON" position.
4. Set the throttle (2) to "half throttle" (= middle position
between "fast" and "slow").
5. Slowly pull out the pull starter (7) until the first resis-
tance is felt.
6. Now pull the pull starter (7) quickly until the engine
starts.
If the product still does not start after 6 pulls, repeat
the procedure as described in 10.1.1.
7. The engine will start.
8. Set the throttle (2) to the working position ("fast") and
the product starts to work.
9. Set the throttle (2) to the idle ("slow") position and the
product runs at idle.
10.2 Stopping the engine (6) (Fig. 9, 10)
10.2.1

the on/off switch (15) to the "OFF" position. The en-
gine (6) comes to a standstill as quickly as possible.
10.2.2
1. Set the throttle (2) to the idle ("slow") position. The en-
gine (6) goes into idle speed.
