TO START MACHINE
NOTE: Before starting machine, perform the
pre-start checks.
1. LPG powered machines: Slowly open the
liquid service valve.
NOTE: Opening the service valve too quickly may
cause the service valve check valve to stop the
flow of LPG fuel. If the check valve stops the flow
of fuel, close the valve, wait a few seconds, and
slowly open the valve once again.
2. Gasoline powered machines: When the
engine is cold, pull the choke knob out. Push
choke in after the engine has started and is
running smoothly.
LPG powered machines: When the engine is
cold and exposed to cold temperatures,
press the primer button on the LPG
vaporizer through the hole in the battery
access cover.
3. Turn the on-off switch key to the right.
4. Push the start switch until the engine starts.
Do not operate the starter for more than 10
seconds at a time or after the engine has
started.
NOTE: Do not operate the starter motor for more
than 10 seconds at a time or after the engine has
started. Allow the starter to cool between starting
attempts. The starter motor may be damaged if it
is operated incorrectly.
5. Release the machine parking brake.
6. Drive the machine to the area to be swept.
