Starting The Engine - Cembre SD-9P-ECO Notice D'utilisation Et Entretien

7. STARTING THE ENGINE

7.1) Set the engine switch to the "I" position (Fig. a).
7.2) Repeatedly operate the fuel pump until fuel fl ows through the
overfl ow pipe (Fig. b).
7.3) Only with a cool engine, set the 'choke lever' upwards, on the
left side in starting position (Fig. c); when engine is warm or in case
of high ambient temperature, set this lever downward in working
position (Fig. f).
7.4) Pull sharply on the starting rope and then release slowly; the
engine, before ignition, may require more than one operation (Fig. d).
Do not over-extend the starting rope and always release it slowly
once the motor is running; a sudden release could damage the
starting system.
If the engine does not start, do not repeatedly pull the starting
rope with the 'choke lever' in start position. This could create a fuel
excess in the cylinder and make ignition more diffi cult. In this case,
set the lever in working position and repeat the starting operation.
Once started, change the speed of the engine twice to allow the
remaining air to leave the carburettor.
7.5) Just after starting, accelerate the engine gradually before
starting any activity, then press the accelerator button (Fig. e) till
the 'choke lever' automatically returns, then release the button.
7.6) Allow the engine to warm up for approximately 2 minutes then
completely press the accelerator button and start to drill.
7.7) To stop the engine, set the engine switch to the "O" position.
7.8) Idling speed adjustment:
if necessary, adjust the idling screw (Fig. f), so that the engine
maintains a stable idling speed (2800 rpm).
7.9) Carburettor adjustment
The carburettor has been factory set.
The system controlling the gas emissions from this motor consists of
a carburettor and ignition system
to guarantee the best results.
The carburettor is adjusted to pro-
vide the air/fuel mixture required
to achieve low consumption and
low emission of injurious gas.
The engine will perform at its
optimum after a "running-in"
period of approximately 200
drilling operations.
