TO CHARGE BATTERIES
1. Turn charger timer to “off” position before
disconnecting or connecting batteries
receptacles to charger, and before inserting
or removing the “A.C.” plug from the wall
outlet.
2. Check water level in battery. Water should
cover plates completely. If water is low, add
distilled water, but do not over-fill.
3. Connect battery connectors to charger
connector.

CHARGING MACHINE BATTERIES
4. Battery covers should be braced open, so
that the gases can escape. Otherwise, the
top of the battery eventually develops a
conductive leak between cells and battery
tray.
WARNING: Batteries Emit Hydrogen
Gas. Explosion Or Fire Can Result.
Keep Sparks And Open Flame Away.
Keep Covers Open When Charging.
5. Begin charge by turning timer to
recommended hours. Pilot light and
ammeter indicate charger is on.
6. Batteries are charged when timer reads “off”
or the electrolyte specific gravity indicates
100% charged.
NOTE: The charger may remain connected to the
batteries for occasional extended periods without
harm to the charger or batteries. The charging
rate gradually tapers down as the batteries are
recharged.
ELECTRIC MOTORS
The electric motor brushes should be inspected
and the brush dust should be blown out of the
motor after every 200 hours of operation. If the
brushes have been worn to less than 0.75 in
(20 mm) in length, they should be replaced. If the
commutator is worn or rough, the armature should
be removed. The commutator should be turned in
a lathe, the mica recut, and commutator polished.
Reassemble, and seat the new brushes, using a
brush seating stone. Be sure the rocker arm is set
on the neutral mark.
CONTROL PANEL
The control panel houses the forward and reverse
relays and controls. The components are not user
serviceable -- only trained personnel should be
allowed to work on it.
WARNING: Hazardous Voltage. Shock
Or Electrocution Can Result.
Disconnect Batteries Before Working
On Machine. Only Qualified Personnel
Should Work Inside Panel.
