Battery Care (For Electric-Starting models)
Proper care can extend the life of a Battery. Follow these recommendations to ensure your Battery’s best performance and long
life:
Do not allow the Battery charge to get too low. If the machine is not used, charge the Battery every 4 – 6 weeks. Operate the
Engine for at least 45 minutes to maintain proper Battery charge.
Store an unused Battery in a dry area that does not freeze.
Do not charge an already charged Battery. In theory, you cannot overcharge our Battery with a trickle charger; however, when a
Battery is fully charged and the charger is still on, it generates heat that could be harmful to the Battery. A fully charged Battery
will read 12V-13.2V with a voltmeter.
Do not continue to crank the Engine when the Battery charge is low.
Under normal work conditions, the Battery will not need special attention with the addition of the Electric Dump System. If you
are operating for extended periods with frequent dumps, it might be best to leave the Engine running during stand still periods
to maintain proper charge levels.
Charging the Battery
Operate the engine for at least 45 minutes to maintain proper battery charge. If the battery loses its charge, you will need to use a
trickle charger (like the DR Battery Charger) to recharge it. The charger should have an output of 12 volts at no more than 2 amps.
At 1 amp, the Battery may need charging for as long as 48 hours.
At 2 amps, the Battery may need charging for as long as 24 hours.
Note: Using the Recoil Starter and then running the Engine will not recharge a dead or significantly discharged Battery.
When performing any maintenance, you must first shut off the engine, set the parking brake, wait five minutes to allow parts to
cool and disconnect the spark plug wire, keeping it away from the spark plug.
