FOR SIMULATION USE ONLY
An oil filler cap/dipstick is located on the top of the engine and is accessible
through an access door in the engine cowling. The dipstick is marked to show
upper and lower oil level limits. To minimise possible loss of oil through the
breather, filling the sump to the low mark on the dipstick instead of the high is
sufficient for routine operations. The upper dipstick mark should be used for
flights of 3 hours endurance or longer. For engine oil grade and
specifications, refer to Section 2 of this manual. An oil pressure indicator is
provided on the instrument panel.
WARNING
•
The oil level must be visible on the dip stick. Do not run the engine if the
sump oil level is below the bottom of the dipstick.
Ignition System
Engine ignition is provided by two engine driven transistorised magneto coils,
each running a single spark plug in each cylinder.
Normal operation is conducted with both magnetos on due to the more
complete burning of the fuel-air mixture with dual ignition sources.
The individual magnetos are selected using the two ON – OFF toggle switches
located on the left hand side of the instrument panel.
Starting System
The electrically driven starter motor is mounted at the rear of the engine.
When energised, the starter motor pinion engages a ring gear that is fitted to
the flywheel.
When the master switch is on, pushing the start button energises the starter
motor.
If the engine turns at less than 300rpm no spark will be generated and it will
not fire. The engine requires choke to start when cold.
When hot it does not require choke and may be started with the throttle just
cracked open.
Experience with the individual engine will enable the pilot to make the
correct judgment on this. Weak intermittent firing followed by puffs of black
smoke from the exhausts usually indicates excess choke or flooding.
If the engine is flooded, leave it to stand for approximately 10 minutes before
attempting re-start.
