4.15 WARM-UP
Warm-up the engine at 800 to 1200 RPM for not more than two minutes
in warm weather and four minutes in cold. Avoid prolonged idling at low
RPM, as this practice may result in fouled spark plugs.
Takeoff may be made as soon as the ground check is completed,
provided that the throttle may be opened fully without backfiring or
skipping, and without a reduction in engine oil pressure.
Do not operate the engine at high RPM when running up or taxiing over
ground containing loose stones, gravel or any loose material that may cause
damage to the propeller blades.
4.17 TAXIING
Before attempting to taxi the airplane, ground personnel should be
instructed and approved by a qualified person authorized by the owner.
Ascertain that the propeller back blast and taxi areas are clear.
Power should be applied slowly to start the taxi roll. Taxi a few feet
forward and apply the brakes to determine their effectiveness. While taxiing,
make slight turns to ascertain the effectiveness of the steering.
Observe wing clearances when taxiing near buildings or other stationary
objects. If possible, station an observer outside the airplane.
Avoid holes and ruts when taxiing over uneven ground.
Do not operate the engine at high RPM when running up or taxiing over
ground containing loose stones, gravel or any loose material that may cause
damage to the propeller blades.
4.19 GROUND CHECK
Set the parking brake.
The magnetos should be checked at 2000 RPM. Drop off on either
magneto should not exceed 175 RPM and the difference between the
magnetos should not exceed 50 RPM. Operation on one magneto should
not exceed 10 seconds.
Check the vacuum gauge; the indicator should read 4.8" to 5.2" Hg at
2000 RPM.
