Jump Starting
If unit battery is discharged or run down, unit may be jump started using jumper cables and another battery or vehicle. Consider the following precautions and be careful when jump starting a unit.
Read and understand the following procedure completely before connecting and jumper cables. Use good jumper cables made with #2 gauge (or larger) cables.
-
Verify unit is turned off. If you are using a vehicle, verify its ignition is also turned off.
-
Open front doors on unit. Battery is located to the left of engine.
-
Check discharged battery to verify it is not damaged or frozen. Do not jump start a damaged or frozen battery. Check vent caps to verify they are tight.
-
Identify positive (+) and negative (–) battery terminals.
-
Remove red cover from positive (+) battery terminal on the unit’s battery.

Connect the red positive (+) jumper cable to the positive (+) battery terminal on the unit’s battery. Do not let the other end of the jumper cable touch anything that conducts electricity.
-
Connect the other end of the red positive (+) jumper cable to the positive (+) battery terminal on the good battery.
-
Connect the black negative (–) jumper cable to the negative (–) battery terminal on a good battery. Do not let the other end of the jumper cable touch anything that conducts electricity.
-
Connect the black negative (–) jumper cable to the lower starter mounting bolt on the unit’s engine.
-
If you are using a vehicle to jump start the unit, start the vehicle and let it run for a few minutes. This will help charge the discharged battery.
-
Turn the unit on and let it start automatically or start it manually. If the unit will not crank or start, contact a qualified technician.
Note Some units with microprocessors will show an alarm code and will not try to start the unit until battery voltage is above 10 volts.
-
After the unit starts, remove the jumper cables in reverse order: black negative (–) from the unit starter mounting bolt, black negative (–) from the good battery, red positive (+) from the good battery, and red positive (+) from the unit battery (that was discharged).
