6. MAINTENANCE INSTRUCTIONS
6.1. Daily check
• Take off the engine cowling (if so equipped).
• Check the engine for missing or loose parts as well as for any wear.
• Check the condition of the ignition harness.
• Check the actuating mechanisms for throttle and choke, make certain
that the action of the throttle is smooth.
• Check the oil level and fill if necessary. The oil level should be between
1/2 and 2/3rd of the oil tank dipstick or level gauge after 3 minutes idle
running.
• Check the breather hoses of oil tank. The breather hoses must not
choke.
• Check the oil and fuel system for any leakage.
• Drain the sump(s) to remove water in the fuel tank.
• Check the breather hoses of carburetors. The breather hoses must not
choke. The breather hoses must stay correct position. The correct
position of end of hose is the place between a spring yoke and side of
the float chamber.
• Reattach the engine cowling if equipped.
• With the ignition off, turn the propeller by hand and check the engine
for unusual noises or hard movement and proper compression.
• Before flight engine test run.
Observe the starting behavior. Let the engine warm up, monitoring the
temperatures and pressures. Do a run-up observing the throttle response
(adequate RPM acceleration) and a full-power run-up. (Maximum RPM
depends on the type of propeller and pitch used)
DANGER!
1. Prior to turning the propeller by hand, confirm that.
The ignition and master switches are: OFF
The aircraft is chocked or properly tied down.
2. Cockpit operations must be performed by a trained person.
