TO START MACHINE
NOTE: Before starting machine, perform the
pre-start checks.
1. LPG machines: Check the LPG fuel tank
gauge to see if there is an adequate fuel
supply.
2. LPG 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 service valve, wait a few
seconds, and slowly open the service valve once
again.
3. 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 set.
FOR SAFETY: Before Starting Machine,
Make Sure All Safety Devices Are In
Place And Operate Properly.
4. Cold CONTINENTAL gasoline engines: Pull
out the choke button about three-fourths of
the way. Push choke in after the engine has
started and is running smoothly.
NOTE: Machines with GM engines have an ECU
(Electronic Control Unit) which does not require
any cold starting procedures.
Cold diesel engines: Turn the ignition key to
the “on” position to start the diesel
pre-heater. Wait until the pre-heater lamp
goes off, then proceed to start the engine.
ATTENTION! Do Not Use A Cold Engine
Starting Aid Such As Ether Unless
Directed To By A Representative Of The
Engine Manufacturer.
5. Move the throttle to the “IDLE” position.
