Starting A Warm Engine; Difficult Starting - Partner 422 Instruction Manual

IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the full
extent of the rope as this can cause the rope to
break. Do not let starter rope snap back. Hold
the handle and let the rope rewind slowly.
For cold weather starting, start the unit at full
choke; allow the engine to warm up before
squeezing the throttle trigger.
NOTE
: Do not cut material with the choke/
fast idle lever at the FULL CHOKE position.

DIFFICULT STARTING (or starting a
flooded engine)
The engine may be flooded with too much
fuel if it has not started after 10 pulls.
Flooded engines can be cleared of excess
fuel by pushing the choke/fast idle lever in
completely (to the OFF CHOKE position)
and then following the warm engine starting
procedure listed above. Ensure the ON/
STOP switch is in the ON position. Starting
could require pulling the starter rope handle
many times depending on how badly the unit
is flooded. If engine fails to start, refer to the
TROUBLESHOOTING TABLE.
