Stopping Of The Engine - Rotax Rm1 Benutzerhandbuch

Attention: Do not warm up the engine whilst the vehicle is still on the trolley. As no load is
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

running-in phase. Therefore vary the engine r.p.m. to avoid overheating.
In principle the running-in procedure is finished only after the initial 5 hours. During

New or renewed brake pads need to be run in .to avoid glazing and embrittlement of
the brake pad material. Use the brake during the break-in periode (the first 30
minutes) moderately. Avoid short and hard braking from high speeds.

to START position. This would cause damage to the electric starter.
The electric circuit for the ignition unit should be closed by setting the switch to „ON"
position only when operating the engine. When the engine is at standstill and the
switch at "ON" position, the ignition unit consumes current and discharges the
battery. This may cause deep-discharging of the battery and reduction of its lifetime.
