Check Oil Level, replenish if necessary.
i) Check Oil Level by screwing in cap fully before withdrawing.
ii) Oil level should be between the MAX & MIN marks - but must never be below the MIN
mark.
iii) Before long periods of operation, ensure that the level is at least at the mid position.
iv) Difference in the oil quantity between MAX & MIN mark is 0.75 litres (0.792 US Quarts).
v) See section 11 for first 25 hrs of operation.
vi) Overfilling is detrimental to the engine.
Check security of spark plugs, leads & electrical connections.
Check lubrication & fuel system for leaks.
i) Visually inspect for signs of leakage on the ground where the aircraft was parked
overnight.
ii) Inspect the oil cooler for leaks through the cowl opening.
iii) Visually inspect the underside of the aircraft for fresh oil or fuel residue.
Check exhaust system for security & leaks.
i) Wriggle the exhaust tail pipes by hand, checking for excessive movement, rubbing on
cowls or unusual noises.
With Ignition & Master OFF and throttle closed, turn propeller by hand & observe engine for odd
noises or heavy movements. Check for regular compression. If irregular, refer to Trouble
Shooting Section of this manual for corrective action.
CAUTION:
Prior to pulling through the propeller by hand, both ignition circuits & the Master must be
switched OFF, the brakes applied & the throttle closed.
WARNING
A hot engine may fire with the ignition/s switched OFF.
DO NOT TURN OVER A HOT ENGINE BY HAND
CAUTION:
Common cause of low compression is poorly sealing valves. Continued operation in this condition
will result in damage to valves, valve seats, valve guides & overhead gear.
Prior to takeoff - follow the Starting & Warm Up procedure, observe the engine behavior &
throttle response.
Check temperatures & pressures. Conduct a short ground test at full power (a few seconds
Max.) (consult aircraft Flight Manual).
NOTE:
Prolonged running at full power on the ground can cause engine overheating & damage
unless special, oversized air ducts and oil coolers are used.
