ACTIVATING DRY-TYPE BATTERIES
Some new batteries are supplied in a dry-type
form. These batteries need to be activated by
filling them with electrolyte before they can be put
into service.
TO ACTIVATE DRY-TYPE BATTERIES
1. Extinguish all cigarettes, fire, and
spark-producing equipment in the area.
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep
flames and sparks away. Keep covers
open when charging.
2. Remove the batteries from the shipping
crate or the machine and place on a level
surface.
3. Remove and save the battery vent caps; or
if ventless plugs were provided, remove and
discard them.
4. Carefully fill each battery cell with battery
grade sulfuric acid to 0.38 in (10 mm) above
the battery plates.
5. Check the specific gravity of the batteries.
Charge the batteries until the specific
gravity is 1.26 to 1.28.
6. Add battery acid if necessary to 0.38 in
(10 mm) above the battery plates.
7. Insert battery vent caps in the vent holes.
8. Clean the battery posts and cables.
9. Install the batteries in the machine.
10. Connect the battery cables to the batteries.
See the STANDARD MODEL PARTS
section for correct cable connections.
11. Fill the batteries with water, if necessary, up
to the electrolyte indicator rings. Do not add
battery acid to the batteries after inserting
the vent caps.
ELECTRIC MOTOR
The electric propelling motor is repairable.
Blow out the dust and inspect the motor brushes
in the motor after every 400 hours of operation.
If the brushes have been worn to less than 0.38 in
(10 mm) in length, replace them.
If the commutator is worn or rough, the motor
armature should be removed and serviced.
