HOW IT WORKS
Home
Find...
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 ESt option 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.
E
D
00116
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.
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 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.
2-8
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.

EDGE SCRUB SWITCH
The edge scrub switch extends the scrub head to the right to allow close edge scrubbing.
To operate the edge scrub, press the edge scrub switch during normal scrubbing. To turn off the edge scrub, press the edge scrub switch again.
BATTERY DISCHARGE INDICATOR
The battery discharge indicator indicates the charge level of the batteries. It displays the charge level when the scrub brushes are operating.
The display should be on the 1 mark of the gauge when the batteries are fully charged. As the batteries discharge, the display will move near the 0 mark. For best life, the batteries should be recharged when the display nears the 0 mark. If the light near the 0 mark starts to blink, the batteries are fully discharged. At this point, the brushes will automatically raise to limit current draw and to alert the operator of the battery condition. Further operation of the machine could damage the machine or the batteries.
When the machine is left overnight with less than a full charge, the display may at first indicate a full charge. It is reading the surface charge level -- not the true charge level. After running the machine a few minutes, the indicator will give the correct charge level.
NOTE: Do not charge the batteries more often than is necessary to prolong the life of the batteries. Do not allow the batteries to become completely discharged as this will also damage the batteries. See BATTERIES in the MAINTENANCE section.
REAR SQUEEGEE AND VACUUM FAN SWITCH
The rear squeegee and vacuum fan switch , along with the direction of machine travel, control the position of the rear squeegee, and turns on the vacuum fan.
To start the vacuum fan and lower the rear squeegee, press the rear squeegee and vacuum fan switch.
When the machine travels backward, the rear squeegee lifts. This prevents the rear squeegee from being damaged when backing the machine. The rear squeegee will lower again when the machine travels forward.
To raise the rear squeegee and stop the vacuum fan, press the rear squeegee and vacuum fan switch again.
SCRUB BRUSH SWITCH
The scrub brush switch controls the scrub head position and scrub brush rotation.
To lower the scrub head and start the scrub brushes rotating, press the scrub brush switch. When the machine travels forward, the scrub head will lower and the scrub brushes will start rotating. If the machine is stopped for more than 6 seconds, the scrub head raises to prevent scrub brush wear. When the machine travels in reverse, the scrub head raises. Once the machine starts traveling forward the scrub brushes start rotating and the scrub head will lower.
To raise the scrub head and stop the scrub brushes, press the scrub brush switch again.
ELECTRICAL POWER INDICATOR
The electrical power indicator lights when the key-operated switch is turned on and the machine has electrical power.
BRUSH CIRCUIT BREAKER INDICATOR
The brush circuit breaker indicator lights when one or both of the two brush motor circuit breakers have tripped. When the circuit breakers are tripped, the brushes will stop rotating and the scrub head will raise. The circuit breaker(s) must be reset before resuming scrubbing.
510E MM239 (3--91)
HORN BUTTON
The horn button operates the horn. To sound the horn, press the horn button.
KEY-OPERATED ON-OFF SWITCH
The key-operated on-off switch controls all machine power. To allow the machine to operate, turn the key clockwise. To turn the machine off, turn the key counter-clockwise.

CIRCUIT BREAKERS
The circuit breakers are resetable circuit protection devices designed to stop the flow of current in the event of a circuit overload. Once tripped, circuit breakers must be manually reset, after it cools, by pressing the reset button. If the overload which caused the circuit breaker to trip is still present in the circuit, the circuit breaker will continue to stop current flow until the overload is corrected.
The fuse is a one-time circuit protection device designed to stop the flow of current in the event of a circuit overload. Never substitute higher value fuses then those specified in this manual.
The circuit breakers are located to the left of the operator’s compartment near the machine and battery connectors. The fuse is located in the control box.
The following chart shows the various circuit breakers, and the electrical components they protect.
