OPERATION OF CONTROLS
DIRECTIONAL PEDAL
The directional pedal controls direction of travel
and the propelling speed of the machine. Change
the speed of the machine with the pressure of
your foot; the harder you press the pedal, the
faster the machine travels.
Forward: Press the top of the directional pedal
with the toe portion of your foot.
Reverse: Press the bottom of the directional
pedal with the heel of your foot.
Neutral: Take your foot off the directional pedal
and it will return to the neutral position.

OPERATION
13
8210D 330210 (1--98)
BRAKE PEDAL
The brake pedal stops the machine.
Stop: Take your foot off the directional pedal and
let it return to the neutral position. Step on the
brake pedal.
PARKING BRAKE PEDAL
The parking brake pedal sets and releases the
front wheel brakes.
Set: While pressing the brake pedal as far as it
will go, set the parking brake by pressing the
parking brake pedal with the toe portion of your
foot.
FOR SAFETY: Before leaving or
servicing machine; stop on level
surface, set parking brake, turn off
machine and remove key.
Release: Press on the brake pedal to unlock the
parking brake pedal.
IGNITION SWITCH
The ignition switch starts and stops the engine
with a key.
FOR SAFETY: When starting machine,
keep foot on brake and directional pedal
in neutral.
Preheat the glow plugs: Turn the key all the way
counter-clockwise and hold it there until the glow
plug light goes out.
Start: Turn the key all the way clockwise.
Release the key as soon as the engine starts.
Stop: Turn the key counter-clockwise.

OPERATION
8210D 330210 (6--04)
14
STEERING WHEEL
The steering wheel controls the machine’s
direction. The machine is very responsive to the
steering wheel movements.
Left: Turn the steering wheel to the left.
Right: Turn the steering wheel to the right.
STEERING COLUMN TILT LEVER
The steering column tilt handle controls the angle
of the steering wheel.
Adjust: Pull out the tilt handle, then move the
wheel to the desired position and release the tilt
handle.

OPERATION
15
8210D 330210 (6--04)
SCRUB SWITCH
The scrub switch controls the scrubbing
operations. The scrub switch also sets the scrub
brush pressure.
The scrubbing operations include the functions
described below. The scrub head lowers and the
scrub brushes activate. The rear squeegee will
lower and the vacuum fan will start. The solution
system will start, if the solution flow switch is on.
Also, the optional ES system and detergent pump
will start, if the switches are on. The engine speed
will change to fast.
Start: Press the scrub switch. The indicator light
next to the switch will illuminate.
Stop: Press the scrub switch. The indicator light
next to the switch goes out.
Scrub brush pressure: Press and hold the scrub
switch. The brush pressure will scroll through four
settings. The heaviest or fourth brush pressure
setting is called Super Scrub. The pressure
setting selected when the switch is released will
be the new default brush pressure setting.
The brush pressure can be set into four different
positions. Under normal conditions, the brush
pressure should be set in the minimum settings
(one or two downward arrows). Under heavy
grime conditions, the brush pressure should be
set in the maximum settings (three or four
downward arrows). The fourth brush pressure
setting (Super Scrub) is not available when the
machine is scrubbing and sweeping
simultaneously. Travel speed and floor conditions
will affect the scrubbing performance.
NOTE: The brush pressure setting and the
detergent flow rate will default to the last settings
used when the scrubbing operations are started
again.
NOTE: The scrub head will raise when the
directional pedal is in the neutral position. The
rear squeegee will raise when the directional
pedal is in the reverse position.

side brush will lower and activate, and the engine
speed will increase to the fast speed.
Sweeping operations on: Press the sweep
switch. The indicator light next to the switch will
illuminate.
Sweeping operations off: Press the switch again.
The indicator light next to the switch will go out.
Sweeping in wet conditions: Press the vacuum
fan switch to disable the fan. The indicator light
next to the switch will go out.
NOTE: If the hopper is raised, even slightly, the
raised hopper icon will replace the sweep icon on
the control panel display and the sweeping
operations will not start.
SIDE BRUSH SWITCH
The side brush switch controls the side brush
position and rotation. The main sweeping brush
must be operating for the side brush to work.
NOTE: The side brush operates automatically
when the main sweeping brush starts operating.
To sweep without using the side brush, press the
side brush switch.
Up and Off: Press the switch again. The indicator
light next to the switch will go out.
Down and On: Press the switch. The indicator
light next to the switch will illuminate.
NOTE: The side brush operates automatically
when the main sweeping brush starts operating.

HOURMETER
The hourmeter records the number of hours the
machine has been operated. Check the hourmeter
regularly; this information is used to determine
when to perform routine machine maintenance.
FUEL LEVEL GAUGE
The fuel level gauge indicates the amount of fuel
remaining in the fuel tank. When the indicator bar
is fully shaded, the fuel tank is full. The fuel tank
is nearly empty when only a small portion of the
indicator bar remains shaded. Refill the fuel tank
as soon as possible.
