mately 10 - 15 minutes to fully warm up all sys-
tems.

for proper operations before working with the
machine.
Cold Weather Engine Starting Procedure

that will keep engine block and oil warm for easier
cold weather starting.

for the ambient (air) temperature.
Note: Be sure battery is fully charged.
1. Follow all steps under “Engine Start Procedure”
above.
2. Advance the throttle to 1/4 engine speed for a
faster warm up.
3. As the engine warms up, move the throttle lever to
the idle position.
