The 912/912S engine needs to be thoroughly warmed up before take off. In the winter this can take up to 10
minutes. Apply the parking brake, set no more than 2500 RPM and allow the Oil temperature to climb to 50°
Celsius minimum, see also the Engine Operators manual.
Note: P&M Aviation have a range of oil and water radiator covers available for those who operate in cold
conditions (20
°
C/ 66
°
F or less), see section 2.11 for instructions for use.
The brakes will hold against a moderate power run-up but the aircraft may slide on wet grass or slippery
surfaces or indeed on more powerful options, on any surface. In this case check the engine at reduced
RPM. During this operation the pilot must be mentally prepared to switch off the ignition at very short notice.
If the engine is stopped after a period of running, the ignition should be switched off at tick over. Switching off
at high rpm floods the engine, distorts the cylinders through rapid cooling and makes restarting difficult.
The brakes/parking brake are not designed to
hold the aircraft against a full power run-up.
Exercise extreme caution when ground running
the engine.
When starting an aircraft engine it is essential that you keep spectators well clear of the immediate
area and ensure that all spectators children and pets are totally under the control of a responsible
adult. On certain surfaces stones can bounce into the propeller blades and can then become
projectiles. Do not start an engine if any loose stones are in the vicinity of the aircraft with any
spectators present at all. A stone picked up by a propeller can travel at high speed for hundreds of
metres (yards).
Taking off without completing the proper warm up procedure may result
in premature mechanical wear in your engine, carburettor icing and
possibly engine failure on take off. Always warm your engine thoroughly
before take off.
The pilot must always be in the aircraft, helmet
and harness properly fitted, during run-up. Use
ONLY the foot throttle during run-up, and be
ready to turn off at the ignition switch. Failure
to follow these instructions could result in injury
or death.

If the LED voltmeter remains red after start, it is possible the starter motor has not disengaged, with
possible damage/fire risk. Stop engine and investigate.
Also stop engine if oil pressure does not rise within 20 seconds.
