HOW IT WORKS
The Model 510E is a rider scrubber. The machine
is propelled by a electric motor via the front wheel.
The machine is steered with the steering wheel
and is very responsive.
The main scrubbing components include a
solution tank, two disc-type brushes, rear and side
squeegees, a vacuum fan, and a recovery tank.
Water and detergent solution flows from the
solution tank through the water control valve to
the scrub brushes. The rotating scrub brushes
scrub the floor. As the machine moves forward,
the squeegees collect the dirty solution and
channel it into the vacuum of the squeegee
pick-up hose. The pick-up hose deposits the dirty
solution in the recovery tank.
Machines with the EStoption filter the dirty
solution in the recovery tank and return it to the
solution tank.

BRAKE PEDAL
The brake pedal operates the brakes on the two
rear wheels.
To stop the machine, return the direction control
pedal to neutral, then apply pressure to the brake
pedal.
DIRECTIONAL PEDAL
The directional pedal controls the propelling drive.
The pedal is used to select the direction of travel
and the speed of the machine.

DIRECTIONAL PEDAL POSITIONS
A. “Reverse” Position
B. “Neutral” Position
C. “Forward” Position
D. “Heel” Portion
E. “Toe” Portion
Gradually press the “toe” portion of the pedal for
forward travel or the “heel” portion for reverse
travel. Regulate the machine speed by varying the
pressure on the pedal.
The machine will coast for a short distance before
changing direction when it is moving and the
directional pedal is reversed. Use the brakes to
stop the machine.
FOR SAFETY: When Using Machine, Use
Brakes To Stop Machine.
STEERING WHEEL
The steering wheel controls the front drive wheel.
The machine is very responsive to the movement
of the steering wheel. The operator should use
care until he or she becomes experienced in
guiding the machine.
SOLUTION FLOW LEVER
The solution flow lever controls the flow of
solution to the floor. To start the solution flow,
push the lever slightly up. To increase the solution
flow to maximum, push the lever all the way up.
To stop the solution flow to the floor, pull the lever
all the way down.
CLOGGED VACUUM INDICATOR
The clogged vacuum indicator lights when
the vacuum system is obstructed and the vacuum
is no longer picking solution from the floor.
When the clogged vacuum indicator lights, check
the vacuum system hoses for obstructions
starting at the rear squeegee pick-up hose.
RECOVERY TANK FULL INDICATOR
The recovery tank full indicator lights when
the recovery tank is full.
HOUR METER
The hour meter records the number of hours
the machine has operated. This information is
useful in determining when to service the
machine.
BRUSH PRESSURE INDICATOR AND SWITCH
The brush pressure indicator shows the
brush pressure selection. The brush pressure
switch controls how aggressive the brushes
are scrubbing the floor.
The brush pressure switch has four positions.
Under normal conditions, the brush pressure
should be set in the light zone. Under heavy grime
conditions, the brush pressure should be set in
the heavy zones. Travel speed and floor
conditions will affect the scrubbing performance.
To change the brush pressure, touch the brush
pressure switch. Each time the switch is touched,
it will increase brush pressure until it reaches the
maximum setting. Then it will return to the
minimum setting as shown on the pressure
indicator.
