Stop Of The Engine - Rotax Rm 1 Benutzerhandbuch

Attention: Do not warm up the engine as long as the vehicle is still on the trolley. As no
load is required from the engine, the fuel/air mixture flowing in cools the
engine, thus it will not reach its operating temperature. Also the engine may
overrev, with consequent engine damage.
Operate the vehicle driving on the racing circuit for 15 minutes with constantly alternating
load and r.p.m. up to an engine speed of 7.500 r.p.m.
Then operate the vehicle driving on the racing circuit for 15 minutes with constantly
alternating load and r.p.m. up to an engine speed of 9.500 r.p.m.
Vary the r.p.m. as follows:
Press the throttle pedal down until the engine has reached the above mentioned r.p.m., then
release the throttle pedal until the engine speed has dropped to 5.000 r.p.m., then press the
throttle pedal again fully down.
Attention: Prolonged operation (more than 5 seconds) both at high or low r.p.m. makes the
temperatures in the engine rise which may cause engine damage in the critical
running-in phase. Therefore vary the engine r.p.m. to avoid overheating.
Note: In principle the running-in procedure is finished only after the initial 5 hours. During
this period the carburetor jetting should be rather at the richer side (bigger main jet)
and the vehicle be driven with a longer gear ratio.
After the running-in phase the full engine potential can be used.

3.3. Stop of the engine

Set the switch to "OFF" position. This interrupts the ignition circuit and the engine stops.
Note: This switch is also the emergency stop switch in case the engine must be stopped
(e.g. if the carburetor slide remains stuck at full throttle).
Attention: When stopping the engine take care that the engine is not set unintentionally
to START position. This would cause damage to the electric starter.
Note: The electric circuit for the ignition unit should be closed by setting the switch to „ON"
position only for operating the engine. When the engine is at standstill and the
switch is at "ON" position, the ignition unit consumes current and empties the
battery. This may cause deep-discharging of the battery and reduction of its lifetime
and remaining damage.
