CAUTION
An after-fire (recognized by a rapid increase in TOT) can occur
during shutdown if fuel cutoff is not complete. If an after-fire
occurs, immediately engage starter and motor the engine to
minimize the temperature encountered. To extinguish the fire,
continue motoring the engine with the twistgrip in CUTOFF
position and pull out the fuel shutoff valve. Observe TOT
limits. After assuring fire is extinguished, within 15 minutes
re-open fuel shutoff valve (to relieve fuel pressure build-up in
fuel system).
NOTE: Immediately after closing twistgrip to CUTOFF position, a
dual tachometer needle split should occur with N
R
lagging behind
N
2.
If no needle split occurs, check overrunning clutch for proper
operation in accordance with HMI. To ensure throttle cutoff, hold
twistgrip in CUTOFF position until N
1
decelerates to zero and TOT
is stabilized. Check for TOT decrease.
