in an area at least 3 metres from where you
refilled the fuel tank.
Before starting the engine:
– Place the machine firmly on the ground.
– Remove the guard from the blade (if used).
– Make sure the blade (if used) is not touching
the ground or any other object.

3.1.1 Cold starting

WARNING! A "cold" start of the engine
means starting it after at least 5 minutes from
when it was switched off or after refuelling.
To start the machine (Fig. 9):
1. Models SBC 627 K/KD – 635 K/KD
643 KD – 645 K/KD/KF – 653 KF:
Set the switch (1) to position «I».
Models SBC 653 K/KD:
Set the switch (1) to position «I».
Press the lock lever (3), activate the throttle
(2) and holding them in this position, press
the shutter (1a) button, then release the le-
ver (3) and the throttle (2), so the button (1a)
stays pressed.
2. Operate the choke, turning the lever (5) to the
«B» position".
3. Press the primer device button (6) 3 or 4 times
to prime the carburettor.
4. Hold the machine firmly on the ground with
one hand on the power unit, in order not to
lose control of the machine during startup
(Fig. 10).
IMPORTANT To prevent distortions, the drive
tube must not be used as a support for the hand
or knee during startup.
5. Pull the starter grip slowly for 10 - 15 cm un-
til you feel some resistance, then tug it a few
times until you hear the engine turn over.
IMPORTANT To avoid breaking the starter ca-
ble, do not pull the whole length of it or let it slide
along the edge of the cable guide hole. Release
the starter grip gradually, to avoid letting it fly back
uncontrollably.
6. Pull the starter grip again until the engine
starts as normal.
WARNING! Starting the engine with the
choke engaged causes the cutting device to
move, only stopping when the choke is dis-
connected.
7. Models SBC 627 K/KD – 635 K/KD
643 KD – 645 K/KD/KF :
Briefly activate the throttle (2) to bring the
engine down to minimum, with the lever (5)
which will move automatically to the «A» po-
sition.
Models SBC 653 KF:
As soon as the engine is started, disengage
the choke turning the lever (5) to the «A» posi-
tion and briefly operate the throttle (2)
Models SBC 653 K/KD:
As soon as the engine is started, disengage
the choke turning the lever (5) to the «A» po-
sition and briefly operate the throttle (2) to dis-
engage the shutter (1a) and bring the engine
down to minimum.
8. Let the engine run idle for at least 1 minute
before using the machine.
IMPORTANT If the starter grip is pulled repeated-
ly with the choke on, it may flood the engine and
make starting difficult.
If you have flooded the engine, remove the spark
plug and gently pull the starter grip to eliminate
any excess fuel; then dry the spark plug elec-
trodes and replace it on the engine.
