4-5 ELECTRICAL SYSTEM
Regular maintenance is necessary to keep the electrical system in proper working order.
Check daily all electrical wires for cuts, broken wires, potential short circuits, and any
other damage.
Battery Care and Charging
The electric system is designed to provide power for a normal work shift. However, the
charge life of the battery pack depends on machine usage. Plan your work to prevent
unnecessary use of electrical power.
Since the power source for the machine is a battery pack, proper battery care is impor-
tant. Recharge the batteries after each work shift. When the machine is not being used,
the batteries should be charged at least once a week. Normal battery charging time
should be 10 to 12 hours. If the battery is extremely low, charging time may be as long
as 24 hours.
Clean the battery terminals every 6 months. Remove the cables from the battery posts,
clean the battery posts and cable ends to shiny metal, and replace the cables. Always
connect the insulated cable from the starter solenoid to the most positive post. Lubricate
the outside of the battery post connections with petroleum jelly or grease.
Battery Charging Procedure
1. Remove the battery charger cord from its box and plug into a 3-prong 115V
outlet, Figure 4-10.

2. When there is power to the battery charger, a red “ON-CHARGING” LED on
the charger will be lit and the ammeter will display the rate of charge.
