RIDER SCRUBBERS
FACTORY CATS ARE DESIGNED TO CLEAN MACHINE SHOPS, FOOD/BEVERAGE MANUFACTURING OR
PACKAGING, DISTRIBUTION -WHILE STANDING UP TO THE RIGORS OF CONTRACT CLEANING.

WITH TWO SPECIALIZED CLEANING SYSTEMS TO CHOOSE FROM, FACTORY CATS OFFER THE
PERFORMANCE AND CAPACITY REQUIRED TO CLEAN YOUR UNIQUE APPLICATION.
THE "DISK" MACHINES, WITH 39" to 55" SCRUB PATHS, OFFER A GIMBALED BRUSH DRIVE AND 35% - 80%
MORE SCRUBBING POWER THAN COMPETITIVE BRANDS.
THE "CYLINDRICAL" MACHINES, OFFER ALL THE PERFORMANCE OF DISK SCRUBBERS PLUS THE ABILITY TO
SWEEP. THE CYLINDRICAL PICKS UP WOODCHIPS, NAILS, BROKEN GLASS, GRAVEL, AND METAL CHIPS.
THE DEBRIS IS HELD IN THE SLIDE-OUT HOPPER WHICH PERMITS EASY DISPOSAL.
PRODUCTIVITY IS A FUNCTION OF SCRUB WIDTH, RUN TIME AND TANK CAPACITY. THESE FACTORY CATS
TOP THE CHART, WHILE MAINTAINING UNSURPASSED MANUVERABILITY. WITH LARGER TANKS, WIDER
SCRUB PATHS, HIGHER SCRUBBING PRESSURES, MORE VACUUM, AND WITH BIGGER BATTERY PACKS
YOU WILL HAVE LESS STOPPING TO REFILL, FEWER TRIPS DOWN THE AISLE, LESS DOUBLE SCRUBBING,
DRY SAFE CLEAN FLOORS, AND EXTRA RUN TIME.
THE OPERATOR SITS IN A SPRING- SUSPENSIONED, FULLY ADJUSTABLE, MID-BACK CHAIR. THE STEERING
COLUMN HAS FOUR SETTINGS, FURTHER ENHANCING OPERATOR COMFORT. HEADLIGHT, HORN,
BACKUP ALARM, AND ARMRESTS ARE STANDARD. OPERATORS ARE ABLE TO TURN WITHIN A 84" AISLE,
WHILE MAINTAINING EXCELLENT WATER CONTROL. WE ALSO OFFER, FOR CLEANING IN REMOTE
AREAS, A COMPLETE LINE OF HAND TOOLS, INCLUDING VACUUM WANDS, SPRAY HOSES, AND
POWERED SCRUB WANDS.
FACTORY CATS EXCLUSIVE "CENTRAL COMMAND II" ENERGY MANAGEMENT SYSTEM OFFERS
AUTOMATIC CONTROLS. WHEN THE OPERATOR STOPS THE MACHINE, BRUSHES, AND SOLUTION FLOW
STOPS, THE SAFETY-SET PARKING BRAKE IS APPLIED, AND THE VACUUM STOPS AFTER A 40 SECOND
DELAY. ALL "CENTRAL COMMAND II" COMPONENTS, INCLUDING THE CONTROLLER, MANUAL RESET
CIRCUIT BREAKERS, AND MARINE DUTY SWITCHES, ARE IN A SEALED MODULE.
FACTORY CATS USE THE MOST POWERFUL MOTORS AVAILABLE, SO THEY ARE TYPICALLY RUN AT ONLY

50% OF THEIR CAPACITY. THIS LEAVES POWER IN RESERVE FOR TIMES WHERE HEAVY STRIPPING IS
REQUIRED, AND GREATLY PROLONGS MOTOR LIFE. THESE FACTORY CATS ARE CONSTRUCTED OF
HEAVY GAUGE STEEL, AND SPECIALLY PLATED OR POWDER PAINTED TO PROTECT YOUR INVESTMENT.
THE STAINLESS STEEL TANKS HAVE EXTRA THICK WALLS. STEEL BUMPERS PROTECT THE SCRUBHEAD AND
FRONT END FROM COLLISION DAMAGE. THE CORNER ROLLERS ARE POLYURETHANE, AND TALL TO
DISPERSE THE FORCE OF IMPACT WITHOUT LEAVING MARKS ON YOUR WALLS. THE WHOLE MACHINE IS
PUT TOGETHER WITH STAINLESS STEEL FASTENERS TO HELP PROLONG THE LIFE AND DURABILATY OF YOUR
MACHINE.

TROUBLESHOOTING CENTRAL COMMAND II
NOTE: THIS MACHINE IS OPERATED BY A SOPHISTICATED ELECTRONIC "BRAIN" THAT HAS MANY FAIL-SAFES WITHIN IT. THE
BRAIN SELF-ANALYZES PROBLEMS AND FLASHES A FOUR-DIGIT NUMERIC CODE OF WHAT IS WRONG IN THE LCD WINDOW.

MOST OF THESE CODES REQUIRE A TECHNICIAN'S ATTENTION. YOU SHOULD NOT ATTEMPT REPAIRS YOU ARE UNFAMILIAR
WITH, ESPECIALLY IF YOU ARE NOT AUTHORIZED TO WORK ON THIS EQUIPMENT.
THE COMPLETE LIST OF CODES IS PUBLISHED IN THE SIMPLIFIED ELECTRONIC TROBLESHOOTING MANUAL, WHICH IS
AVAILABLE TO TECHNICAL PEOPLE. HOWEVER, WE HAVE INCLUDED THE BASIC CODES THAT YOU CAN USUALLY RESOLVE
YOURSELF.

1. 1E03 AND 1E04 ERROR. CHECK THE SMALL SAFETY

SWITCH NEXT TO THE RED PLUG BELOW THE DASHBOARD.
THIS SWITCH WILL TURN OFF THE TRACTION DRIVE AND
BRUSHES AS A SAFETY FEATURE WHILE THE CHARGER IS
PLUGGED IN. THE SWITCH MAY BE STUCK, OR THE PLUG
TWISTED AT AN ANGLE, ENGAGING THE SWITCH. THIS
CODE WILL ALSO FLASH IF THE WIRING BECOMES VERY
WET. IN THIS CASE, EITHER WAIT UNTIL THE WIRING DRIES
OUT, OR CALL A TECHNICIAN.
(FIGURE 52.)
7601 AND 7602 ERROR. SCRUBDECK CURRENT OVER
LOAD. THIS CAN CAN OCCUR WHEN DRIVING OVER A
BUMP IN THE FLOOR. TO RESTART, TURN OFF THE KEY AND
TURN IT ON AGAIN. TO AVOID THIS ERROR, EITHER SLOW
DOWN ON BUMPY PARTS OF THE FLOOR, OR REDUCE
DOWNPRESSURE ON THE PADS.
2.

(FIGURE 53.)
3. 1600 ERROR. VOLTAGE EXCEEDS THE MAXIMUM.

EITHER THE BATTERIES ARE MIS-WIRED, OR THE CHARGER IS
STILL PLUGGED INTO THE MACHINE.

(FIGURE 54.)
4. 7700, 7701, 7702, AND 7703 ERROR. THE VACUUM

MOTOR HAS EXCEEDED THEIR AUTHORIZED POWER LIMITS.
TURN OFF KEY AND TURN ON AGAIN TO CLEAR.

(FIGURE 55.)

PAGE 22

TROUBLESHOOTING CENTRAL COMMAND
5. 7900 AND 7901 ERROR. THE EMERGENCY STOP BUTTON

IS OUT

(FIGURE 56.)
6. THROTTLE ERROR. YOU PRESSED THE FOOT PEDAL

BEFORE TURNING ON THE KEY. TURN OFF THE KEY AND TRY
AGAIN, LEAVING FOOT OFF OF THE PEDAL.

(FIGURE 57.)
7. 2C00 AND 2C01 ERROR. LOW VOLTAGE WARNING.

VOLTAGE HAS DROPPED DOWN BELOW THE MINIMUM
REQUIRED TO OPERATE THE MACHINE. IF YOU WAIT A FEW
MINUTES, THE BATTERIES MAY COME UP IN VOLTAGE,
ALLOWING YOU TO DRIVE VERY SLOWLY TO THE
RECHARGE STATION. IF NOT, YOU WILL HAVE TO RELEASE
THE PARKING BRAKE ( ON THE FRONT WHEEL, PULL LEVER
TOWARD THE FRONT OF THE MACHINE TO RELEASE) AND
PUSH THE MACHINE TO RECHARGING STATION.
MUST DISCONNECT THE TRACTION MOTOR!
(FIGURE 58.)
8. 7802 ERROR. THE TRACTION MOTOR WAS USED TO

CLIMB A RAMP, AND WAS RUNNING UP THE RAMP FOR
MORE THAN THE 60 SECONDS ALLOWED FOR THIS. TURN
OFF THE KEY, TURN ON AGAIN, AND CONTINUE. YOU
SHOULD NOT USE THIS MACHINE TO CLIMB RAMPS SO
STEEP AND SO LONG THAT THIS CODE COMES UP
REPEATEDLY, OR YOU COULD OVERHEAT THE TRACTION
MOTOR.

(FIGURE 59.)
9. ALL OTHER ERROR CODES. TURN OFF THE KEY, AND DISCONNECT THE POSITVE BATTERY CABLE FROM THE BATTERIES

FOR MORE THAN ONE MINUTE (THE TIME IS NEEDED TO DRAIN THE BRAIN'S ON-BOARD CAPACITOR). RECONNECT
CABLES, BEING SURE THAT IT IS TIGHT. TOO LOOSE AND YOU WILL BURN BATTERY. IF YOU OVERTIGHTEN THE CABLES YOU
CAN DAMAGE THE BATTERY'S LEAD TERMINAL. TRY AGAIN.
10. IF THE PROBLEMS CANNOT BE SOLVED BY ANY OF THESE SOLUTION CALL YOUR LOCAL DEALER'S SERVICE
DEPARTMENT.
