Defective wheel drive motor - follow instructions below to test.
• Jack up the front of the machine to lift the drive wheel off the floor.
• Turn Key Switch (11) OFF.
• Disconnect one of the battery cables.
• Remove the back panel from control handle.
• Disconnect the white/green wire from the M2 terminal on the speed control. Connect this wire to one of the B+
terminals (also on the speed control).
• Disconnect the blue wire from the M1 terminal on the speed control. Connect this wire to one of the B- terminals
(also on the speed control).
• Reconnect the battery cable and then turn key ON. If the wheel motor turns, go to steps 3. If the wheel motor does
not turn, remove the tanks and batteries, tip the machine on its side and repair or replace the wheel drive motor.
3
Defect in potentiometer mechanism - follow instructions below to test.
• Make sure that the white, green and black wires are firmly connected to the potentiometer. The white wire should
be on the potentiometer terminal closest to the front of the machine, the green wire on the center terminal and the
black wire on the terminal closest to the back of the machine.
• Disconnect the potentiometer plug (the one with the green, black and white wires) from the speed control.
• Connect an ohmmeter to the green and white wires. NOTE: Inserting a paper clip into the plug end will help in the
attachment of the test leads. Meter should read 2400 - 2600 ohms in neutral and increase to 5000 ohms when the
twist grips are turned to the full-forward position. If you do not get these readings, follow potentiometer adjustment
instructions. If you do get these readings, go to the next test.
• Connect an ohmmeter to the green and black wires. Meter should read 2400 - 2600 ohms in neutral and decrease
to 100 - 300 ohms when the twist grips are turned to the full-forward position. If you do not get these readings, follow
potentiometer adjustment instructions. If you do get these readings, the potentiometer is OK — replace the speed
control.
WHEEL DRIVE SYSTEM
______________________________________________________________________________________________
POTENTIOMETER ADJUSTMENT
Adjust the potentiometer if the machine has no drive, or if it moves with the twist grips in neutral. To adjust the
potentiometer...
1
Remove the back panel from the control handle.
2
Carefully inspect the potentiometer belt and pulley mechanism for a mechanical defect, correct defects before
proceeding.
3
Carefully pull the potentiometer connector (the one with the green, black and white wires) off of the speed control.
4
Connect an ohmmeter (on 0 x 100 scale) to the green and white wires on the connector. The meter should read
between 2400 and 2600 ohms. If it does not, go to the next step.
5
Loosen the (2) set screws (using a 5/64 Allen wrench) in the potentiometer pulley and slide it off of the potentiometer
shaft (if the potentiometer shaft does not have a slot in the end of it) (if it does, use a screw driver to adjust the
potentiometer after loosening the pulley set screws).
6
Turn the potentiometer shaft until the ohmmeter reads between 2400 and 2600 ohms.
7
Slide the pulley back onto the potentiometer shaft, being careful not to turn the shaft.
8
Test the drive system for proper operation before reinstalling the back panel.
BATTERY SYSTEM
______________________________________________________________________________________________
WARNING!
Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact
skin or eyes. Explosive hydrogen gas is vented from inside the batteries through openings in the battery caps. This gas
can be ignited by any electrical arc, spark or flame.
When working with batteries:
•
Remove all jewelry.
•
Wear chemical goggles, rubber gloves and a protective apron.
•
Do not smoke.
•
Do not allow tools to touch more than one battery terminal at a time.
•
Work in a well-ventilated area.
•
Do not fill the batteries before charging.
______________________________________________________________________________________________
BATTERY MAINTENANCE
Proper maintenance of electric vehicle batteries can greatly extend their life. Well-maintained batteries may last up to 3
years, but failure after 1 year is common if maintenance has been poor.
There are 3 simple rules for good battery maintenance:
•
Maintain Proper Electrolyte Level – Check the electrolyte level of the batteries at least once a week. Use distilled
water in batteries whenever possible. If batteries are discharged, add just enough water to cover the plates in each
cell. After batteries are fully charged, fill each cell to the bottom of the filler tube. Do not over-fill the batteries! Do
not add acid to batteries!
•
Keep the Batteries Charged - Batteries should be charged each time that a machine is used for more than 1 hour
or when the Battery Meter (17) indicates batteries are empty. Machine operators should tip the solution and recovery
tank to the side of the machine for charging, to avoid a concentrated build-up of hydrogen gas. Push the connector
from the charger into the Power Connector (5). Operators should follow the instructions provided with their specific
battery charger, to determine how long the batteries should be charged. Even when a machine is stored, the batteries
should be charged once a month to prevent the batteries from “sulfating”. Almost all battery caps are vented, so
there’s no need to loosen or remove them for charging.
•
Keep the Batteries Clean - Use a damp cloth to wipe dirt and liquid from the top of the batteries. Battery terminals
must be clean and tight. If the top of the batteries are wet after charging, the batteries have probably been over-filled.
Always wipe water and acid from the top of the batteries after charging. If there is acid on the batteries, wash the
tops of them with a solution of baking soda and water (2 tablespoons of baking soda to 1 liter of water).
BATTERY SYSTEM
______________________________________________________________________________________________
BATTERY TESTING
A battery problem is usually recognized by the machine operator, as a decrease in the machine’s running time. This
condition is usually caused by one (or more) “dead cell” in the battery system- that is, one (or more) cell that is putting out
less voltage than the other cells.
Note: Always charge batteries before testing.
There are 2 ways to find a dead cell:
•
Use a hydrometer to check the specific gravity (or “state of charge”) of the fluid in each cell. A dead cell is one that
reads 50 points (or more) lower than the other cells.
•
Use a volt meter to check the voltage of each battery with the brush and vac motors running. The battery with the
dead cell will read 1 or 2 volts lower than the other batteries in the system.
If the batteries in the machine are more than 1 year old, it’s usually best to replace the whole set, rather than replacing
just one battery.
