TO START MACHINE
NOTE: Before starting machine, perform the pre-start

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.
Diesel powered machines: Push the diesel
preheat pushbutton until the preheat indicator
glows brightly.
2. The machine operator must be in the
operator’s seat with the directional pedal in the
“neutral” position and with a foot on the brake
pedal or with the parking brake engaged.
FOR SAFETY: Before starting machine make sure
all safety devices are in place and operate
properly.
3. Gasoline powered machines: When the engine
is cold, pull out the choke knob about
three-fourths of the way. Push the choke in after
the engine is running smoothly.
LPG powered machines: When the engine is
cold and exposed to cold temperatures, open
the engine cover, press the primer button on
the LPG vaporizer, close the engine cover.
4. Place the throttle control in the (Idle) position.
5. Turn the ignition switch key clockwise. Press
the start switch until the engine starts. Do not
