4.4) Starting and stopping the engine
Always start the machine at a safe distance from the re-
fuelling 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 acce-
lerator block and then release the accelerator, it will lock in the
starting position (Fig. d).
• Ground start-up (Fig. e): grasp the upper handle with one hand
and place one foot on the inside of the rear handle in order to
push the rail saw against the ground.
–
Gently pull the starter rope until you feel some resistance
(the starter hooks will kick in) and then pull vigorously with
rapid and decisive movements until the engine starts.
Note: To avoid damaging the winding device, accompany the
starter rope 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
starting work.
– Turn off the engine and mount the rail saw on the support arm.
