OPERATION OF CONTROLS
BRAKE PEDAL
The brake pedal stops the machine.
Stop: Take your foot off the directional pedal and
allow it return to the Neutral position. Step on the
brake pedal.
PARKING BRAKE PEDAL
The parking brake pedal sets the front wheel
brake.
Set: Press the brake pedal down as far as
possible with the right foot, then press on the
parking brake pedal with the toe of your left foot to
lock the parking brake pedal in place.
FOR SAFETY: Before leaving or
servicing machine, stop on level
surface, set parking brake, turn off
machine, and remove key.

DIRECTIONAL PEDAL
The directional pedal controls direction of travel
and the propelling speed of the machine. You
change the speed of the machine with the
pressure of your foot; the harder you press the
faster the machine travels.
When the machine is moving forward and the
directional pedal is reversed, the machine will
coast for a short distance before changing
direction. Use the brake pedal to stop the

SCRUB SWITCH
The scrub switch controls the scrub head, scrub
brushes, squeegee, and vacuum fan. The scrub
switch is also used to set the scrub brush
pressure.
Start scrubbing: Press the scrub switch.The
pressure indicator light will illuminate, the
squeegee will lower, and the vacuum fan will start.
The scrubbing system and solution flow will start
when the directional pedal is pressed and the
machine begins to move forward.
Stop scrubbing: Press the scrub switch.The
pressure indicator light will go out. The scrub
brushes will stop, the scrub head will raise, and
the solution flow will stop. After a short delay, the
rear squeegee will automatically raise. After
another delay, the vacuum will stop.
The brush down pressure indicators display the
pressure selection. The brush pressure indicator
has three positions. Brush pressure increases as
the indicator light moves to the right across the
display. Travel speed and floor conditions will
affect the scrubbing performance. Under normal
conditions, the brush pressure should be set in
one of the minimum settings. Set the brush
pressure in the maximum setting to scrub a
heavily soiled floor.
Change brush pressure: Press and hold the
scrub switch. The pressure indicator light will
cycle through the three brush pressure settings.
When the switch is pressed and held, the brush
pressure will increase until it reaches the
maximum setting. The pressure will then return to
the minimum setting. Release the scrub switch
when the desired setting is indicated on the
display.
NOTE: When the machine power is turned off, the
brush pressure will remain in the last setting used.

REAR SQUEEGEE SWITCH
The rear squeegee switch controls the vacuum
fan and the position of the rear squeegee. The
rear squeegee can be operated separately from
the scrub brushes for the purpose of picking-up
excess water without scrubbing, or double
scrubbing without water pick up
Lower squeegee and start the vacuum fan: Press
the rear squeegee switch. The indicator light
above the switch will illuminate.
Raise squeegee and stop the vacuum fan: Press
the squeegee switch. The indicator light above the
switch will go off. There will be a slight delay
before the vacuum shuts off.
NOTE: The rear squeegee lowers and the
scrubbing vacuum starts automatically, when the
scrubbing operations start.
NOTE: The rear squeegee will raise and the
scrubbing vacuum will shut off after a short delay
when the machine travels in reverse.
NOTE: The rear squeegee will raise and the
scrubbing vacuum fan will shut off after a short
delay when the scrubbing operations are shut off.
RECOVERY TANK FULL INDICATOR
The recovery tank full indicator light will illuminate
when the recovery tank is full.
NOTE: When the indicator illuminates,all
scrubbing functions will shut off automatically.

BATTERY DISCHARGE INDICATOR
The battery discharge indicator displays the
charge level of the batteries while the machine is
operating.
When the batteries are fully charged, all four
indicator lights are lit. As the batteries discharge,
the indicator lights will go out from right to left.
The batteries should be recharged when the
indicator on the left flashes. When the indicator
flashes, all scrubbing functions will shut off
automatically. Drive the machine to the battery
charging area and charge the batteries
immediately after the battery discharge indicator
begins to flash.
NOTE: The battery discharge indicator will not
stop flashing until the batteries have been fully
charged.
NOTE: Do not charge the batteries more often
than is necessary to prolong the life of the
batteries. Do not charge the batteries with a “top
off” charge if there is enough remaining charge in
the batteries for the next machine use. Discharge
the batteries to a 20% level, when the battery
discharge indicator segments shut off, before fully
charging the batteries. Do not allow the batteries
to become completely discharged as this will also
damage the batteries. See BATTERIES in the
MAINTENANCE section.
SOLUTION FLOW LEVER
The solution flow lever controls the amount of
solution that flows to the floor while scrubbing.
Increase solution flow: Push the lever forward.
Decrease solution flow: Pull the lever backward.
NOTE: The machine is equipped with a solenoid
valve that automatically stops the solution flow
when the directional pedal is in the neutral
position or when the scrub head is raised.

CIRCUIT BREAKERS
Circuit breakers are resetable electrical circuit
protection devices designed to stop the flow of
current in the event of a circuit overload. Once a
circuit breaker is tripped, reset it manually by
pressing the reset button after the breaker has
cooled down.
If the overload that caused the circuit breaker to
trip is still present, the circuit breaker will continue
to stop current flow until the problem is corrected.
The circuit breakers are located on the operator
console.
The chart below shows the circuit breakers and
the electrical components they protect.

FUSE
The fuse is a one-time protection device designed
to stop the flow of current in the event of a circuit
overload.
NOTE: Always replace the fuse with a fuse of the
same amperage.
The fuse is located behind the operator console.
Access the fuse by lowering the operator console.

OPERATOR SEAT
The operator seat is designed to be adjusted
forward and backward.
Adjust: Move the lever toward the center of the
seat, slide the seat backward or forward to the
desired position, and release the lever.
NOTE: A seat switch is located under the
operator seat. If there is no weight on the operator
seat, the machine WILL NOT propel in any
direction.
SEAT SUPPORT ARM
The seat support arm holds the seat up to allow
access to the batteries. The support arm
automatically engages when the seat is lifted all
the way up. Lower the seat support by slightly
raising it while pushing the seat support arm
inward.
SQUEEGEE WHEEL CAMS
The squeegee wheel cams adjust the squeegee
deflection along the entire length of the squeegee.
There are wheel cams at either end of the
squeegee.
Increase deflection: Turn the cams
counter-clockwise.
Decrease deflection: Turn the cams clockwise.

EZ Rider 330730 (9--00)
SQUEEGEE LEVELING KNOB
The squeegee leveling knob adjusts the deflection
at the ends of the squeegee.
The squeegee leveling knob is located directly
behind the squeegee suction hose. DO NOT
disconnect the suction hose from the squeegee
frame when leveling the squeegee.
Increase end deflection: Turn the squeegee
leveling knob counter-clockwise to increase the
deflection at the end of the squeegees.
Decrease end deflection: Turn the squeegee
leveling knob clockwise to decrease the deflection
at the end of the squeegees.
HOW THE MACHINE WORKS
The following machine components work together
to effectively clean dirty floors: solution tank,
scrub brushes, squeegee, vacuum fan, and
recovery tank.
Water and detergent from the solution tank flow to
the floor through a solution valve. The brushes
use the detergent and water solution to scrub the
floor clean. As the machine propels forward, the
squeegee wipes the dirty solution from the floor.
The suction created by the vacuum fan then
draws the dirty solution from the squeegee into
the recovery tank.
The steering wheel controls the direction of
machine travel.The directional pedal controls the
speed and direction of the machine. The brake
pedal slows and stops the machine.
The two available 700 mm (28 in) scrub head
types use disk or cylindrical brushes.
NOTE: The amount and type of soilage play an
important role in determining the type of brushes
to be used. For specific recommendations,
contact your Tennant representative.
When finished scrubbing, clean the recovery tank.
