Starting The Engine - Cembre SD-15P-ECO Operation And Maintenance Manual

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) Set the choke lever in the position "|/|";when engine is warm;
in the case of high ambient temperature, this lever may require
setting to either the open or half open position "|ı|" (Fig. c).
7.4) Pull sharply on the starting rope and then release slowly more
than one operation may be required (Fig. d).
Do not over-extend the starting rope and always release it slowly
once the engine is running; a sudden release could damage the
starting system.
If the engine does not start, pull the starting rope, resetting the
choke lever in the fully open position "|ı|".
7.5) Upon starting the engine, gradually move the choke lever to
position "|ı|"; rev the engine at the desired speed by operating the
accelerator control lever (Fig. e).
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 engine consists
of a carburettor and ignition system to guarantee the best results.
The carburettor is adjusted to
provide the air/fuel mixture
required to achieve low con-
sumption and low emission of
injurious gas.
The engine will perform at its
optimum after a "running-in"
period of approximately 200
drilling operations.
