Warning: The brake must be released before performing the roll test. This can be accomplished by supplying 24 Volts D.C. to the gray 2-pin brake connector.

Can you rotate the wheel or hub of the gearbox by hand?

Do you feel more drag in the gears only at certain points?

If you answered 'YES' to the previous question, the gears are not rolling freely and should be examined for improper installation or defects.

Do the gears in your unit seem to roll hard?

If you answered 'YES' to the previous question, do not be concerned as long as they roll with consistency.

NOTE: Batteries in storage should be kept at 12.5V or higher.

Before testing for battery condition, the open circuit voltage should be taken from each battery. If the voltage of the batteries differs by 0.3 volts or more, the lower voltage battery should be replaced.

Battery Testing Can Be Performed In Two Ways:

1. The batteries can be tested using a battery tester capable of testing 12V 100Ah AGM VRLA (Valve Regulated Lead Acid) batteries, using the instructions of the battery tester manufacturer.

2. If an appropriate battery tester is unavailable, the batteries can be tested by fully charging them withthe charger that is installed on the machine. Then check the battery voltage of each battery - 4 hours - after charging is complete. Batteries less than 12.72 volts should be replaced.

NOTE: If a faulty charger is suspected, the batteries can be charged using a charger that supplies 2.45 volts/cell.

Charging should be terminated when the charge current drops below 1 amp.;
