7.2.2 Battery
NOTE
-
The machine comes equipped with a maintenance-free battery that requires no regular
maintenance except the cleaning of the terminals.
DANGER!
- Battery poles, terminals and related accessories contain lead and lead
compounds, chemicals known to cause cancer and damage to the reproductive appara-
tus. Wash hands after handling
Remove battery before servicing.
a)
Battery Removal and Installation
• Disconnect negative (-) cable first, then positive
(+) cable.
• Remove the battery hold-down bracket and bat-
tery from the machine.
• Connect positive (+) cable first, than negative (-)
cable.
• Apply petroleum jelly or dielectric grease to bat-
tery cable ends and terminals.
b) Inspection, cleaning, drying, and mainte-
nance
• Inspect the top of the battery, terminals, cables, poles and the battery unit for any accumulation
of dirt, corrosion cracks or loose or broken parts. Keep the battery and its terminals clean. Re-
place the battery if damaged.
• Clean or service the battery after removing it from the machine. Remove corrosion from battery
terminals and cable connections with a wire brush, then wash with a weak baking soda solution.
• Scrub the exterior of the battery and cable terminals with a nonmetallic brush which has been
dipped into a mixture of baking soda and water.
• After cleaning, apply a thin coat of grease or petroleum jelly to terminals and cable ends to delay
corrosion.
c) Recharging the battery
NOTE
-
ALWAYS follow the information provided on the battery by the battery manufacturer.
Contact the battery manufacturer for further instructions on how to charge the battery.
• To charge the battery:
1. Remove the battery from the machine
2. Place the battery on bench or other well ventilated place.
3. Connect the positive (+) lead of the charger to the positive (+) terminal, and the negative (-)
lead to the negative (-) terminal.
The approximate charge status can be determined by the remaining open circuit voltage (OCV) at
room temperature, and the charge time required can then be estimated, as indicated in the table
of examples.
