BEFORE STARTING THE MACHINE

1Be sure you understand all machine controls and their functions.

2Plan your cleaning route. Arrange long, straight passes with as few turns as possible.

3Check the Brake Pedal (FF). The pedal should be ﬁrm.

If the pedal is “spongy” or fades under pressure, DO NOT DRIVE THE MACHINE. Report all defects immediately to service personnel.

STARTING THE DIESEL ENGINE

1Turn the Key Switch (TT) counter-clockwise to the “Pre-Heat” position and hold it there until the Glow Plug Indicator (FF) turns OFF. Once the indicator turns OFF the engine can be started. Skip this step if the engine has been running and is already warm.

2Turn the Key Ignition Switch (TT) clockwise to the START position and release it as soon as the engine starts. If the engine does not start after cranking for 15 seconds, release the key, wait for 1 minute and try steps 1-3 again.

3Let the engine run at “IDLE” speed for 5 minutes before using the machine.

4Push the Engine Speed Switch (GG) to switch to “FULL THROTTLE” and move the machine around for 2 or 3 minutes at a slow speed to warm up the hydraulic system.

STARTING THE PROPANE / GASOLINE ENGINE

1NOTE: Propane models only: Open the service valve on the LP fuel tank (21).

2NOTE: 3 Cylinder models: Pull the Choke Knob all the way out. (Skip this step if the engine has been running and is already warm.)

3Turn the Ignition Key Switch (TT) clockwise to the START position and release it as soon as the engine starts. If the engine does not start after cranking for 15 seconds, release the key, wait for 1 minute, then try again.

4NOTE: 3 Cylinder models: Once started, push the Choke Knob in slowly until the engine runs smoothly.

5Let the engine run at “IDLE” speed for 5 minutes before using the machine. NOTE: 3 Cylinder models: Push the Choke Knob all the way in.

6Push the Engine Speed Switch (GG) to switch to “FULL THROTTLE” and move the machine around for 2 or 3 minutes at a slow speed to warm up the hydraulic system.

NOTE: ALWAYS operate the machine with the Throttle Control at full throttle. Use the Forward/Reverse Pedal (G) - not the Throttle Control - to control the speed of the machine. The speed of the machine will increase as the pedal is pushed closer to the ﬂoor. Do not press the Forward/Reverse Pedal until the engine has started, this will disengage the starter.
