o Crank starter for 10 sec followed by 20 sec cool down; Repeat two additional times
followed by 10 min cool down period before trying again; Crank starter again, 3 cycles of
10 sec each, followed by 20 seconds of cool down. If engine fails to start, an investigation
to determine the cause is needed

Before Take Off Amplified
Warm Up
If engine idles (approx. 650 RPM) and accelerates smoothy the airplane is ready for take off
Take off with turbo charged engine should not be started if indicated lubricating oil pressure due to
cold temperature is above maximum
o Excessive oil pressure can cause over boost and engine damage
Magneto Check
Switch to R position and note RPM
Switch to Both to clear the other set of plugs
Switch to L position and note RPM
Switch to Both
RPM drop should not exceed 150 RPM on either magneto or show greater than 50 RPM differential
between magnetos
An absence of RPM drop may be an indication of faulty grounding of one side of the ignition system
