Starting And Stopping The Engine - Cembre RDS-20P Operation And Maintenance Manual

4.4) Starting and stopping the engine

ONLY FOR RDSC-20P: Mount the rail saw on to the support
arm before starting the engine. It is not possible to start the engine
on the ground but only when the rail saw is mounted on the arm
otherwise an automatic cut-off device stops the engine!
Always start the machine at a safe distance from the refuelling
area.
Start the engine only when the abrasive cutting disc is mounted.
Before starting, check that the abrasive cutting disc can rotate
freely.
The rail saw can be started both on the ground and mounted on the
support arm. We advise that it is started on the ground fi rst to warm
it up, turned off and mounted on the support arm, then re-started.
– Turn the ignition switch to the left into the starting position (Fig. a).
– Press the decompression valve which makes start-up easier (Fig. b).
– Only when the engine is cold: fully pull the air valve control (Fig. c).
Completely press the accelerator, the interlock lever, the accelera-
tor block and then release the accelerator, it will lock in the starting
position (Fig. d).
– Gently pull the starter cord until you feel some resistance (the starter
hooks will kick in) and then pull vigorously with rapid and decisive
movements until the engine starts (Fig. e).
NOTE: To avoid damaging the winding device, accompany the starter
cord in the return phase and do not pull it over its stroke.
– With the engine running, press and immediately release the acce-
lerator to unlock it from the starting position and let it run idle.
– Release the air valve control, if pulled.
– Keep the engine running for a few minutes to warm it up before star-
ting work.
