Maintenance
Electrical System
The electrical system is a 12-volt negative ground
system. Connect the positive (+) cable to the positive
(+) post of the battery. Connect the ground cable to
the negative (-) post of the battery. It is advisable to
disconnect the negative (-) cable rst and connect it last.
Reversed polarity can damage the electrical system.
Fire and Explosion Hazard! Always
observe battery polarity when connecting a battery
charger or jumper cables to the battery: negative (-)
to negative (-), positive (+) to positive (+). Failure to
do so can produce sparks.
When connecting a booster battery, connect one end
of the rst jumper cable to the positive (+) terminal of
the dead battery and the other end to the positive (+)
terminal of the booster battery. Connect one end of the
second jumper cable to the negative (-) terminal of the
booster battery and the other end to the frame of the
paver with the dead battery.
Fire and Explosion Hazard! Be sure
that the battery charger is in the OFF position before
connecting it to the battery.
Be sure to keep the battery fully charged during cold
weather to keep it from freezing. Freezing weather has
little effect on a fully-charged battery. (Figure 5-21)
Figure 5-21. Battery Location
ALWAYS turn the master battery
switch off when working on the electrical system
or welding anywhere on the machine. Damage to
electrical components could result.
Battery Servicing
Batteries contain sulfuric acid.
ALWAYS wear safety goggles and protective clothing
when servicing the battery.
NEVER allow battery uid to come into
contact with clothing, skin or eyes. If battery uid
contacts the eyes or skin, immediately ush with
clean water and obtain prompt medical treatment.
Keep sparks and ames away from the
batteries as electrolyte gas is highly ammable.
1. Remove the rear access cover to access the
battery.
NOTE: When replacing the battery, discard the old
battery properly.
2. Before connecting the battery, turn off the master
switch, located under the operator control panel.

3. Be certain that battery terminals and posts are clean
and that the battery cable terminals are tight.
Dirty or loose battery connections can
create high electrical resistance and permit arcing.
4. If corrosion is present around terminal connections,
remove and wash with ammonia or a solution of
1/4-pound (.11 kg) baking soda added to one quart
of warm water. Ensure the vent caps are tight to
prevent solution from entering the cells.
5. Pour clean water over the battery and surrounding
area to rinse away the solution.
6. Check vent cap breather openings to ensure they
are clear.
