OPERATING INSTRUCTIONS
To ensure that the engine operates reliably, carefully observe all of the operating &
maintenance instructions.
4.1
Pre-Start Checks
Daily Checks (See Paragraph 5.1)
Move throttle position to FULL & check for ease of movement over the entire range.
Return to idle before attempting to start engine.
4.2
Starting Procedure
Note: Activate Starter for a maximum of 20 seconds, followed by a cooling period of 1
minute.
When engine runs, adjust the throttle to achieve smooth running at approximately
1200 RPM. Deactivate Choke. Check Oil Pressure has risen within 5 seconds - if
not, shut down. It is strongly advised to close choke while cranking on first attempt.
Too much choke will cause over fueling in the venturi (“flooding” the engine) and
loss of start.

depending on ambient temperature, until oil temperature reaches 15
°
C (59
°
F). Check the
two ignition circuits at 2000 RPM. Note: - RPM with only one ignition should not drop by
more than 100 RPM.
DO NOT apply full power until CHT reaches 100
