State of charge as related to specific gravity and open circuit voltage
Battery Installation
Tighten the battery cables to battery terminals with torque of 95 - 105 lbs. in. (10.7
- 11.9 N.M.) Make sure there is nothing else between the battery cable lug and
battery terminal post.
WARNING:
When working with the battery, DO NOT put wrenches or any other
metal objects across the battery terminals, otherwise, an arc can occur, and it may
cause explosion of the battery and physical injury.
Battery should be installed or replaced only by a qualified electrician.
Traction/Motor Maintenance
The motor is designed for use up to 4000 feet above sea level and in a temperature
between -15° F and 105° F.
Never keep the motor running idly. Any mud, sand, and other clinging objects
should be cleaned away.
Check the carbon brush every three months. To change a worn or weakened car-
bon brush, press spring.
Troubleshooting for Motor (DC Motor only)
Warning:
Only a qualified electrician should change and adjust the carbon brush.
