To determine the corrected specific gravity
reading when the temperature of the battery
electrolyte is other than 80
F (27 C):
Add to the specific gravity reading 0.004, 4 points,
for each 10
F (6 C) above 80 F (27 C).
Subtract from the specific gravity reading 0.004, 4
points, for each 10
F (6 C) below 80 F
(27 C).
Eight to twelve hours is generally enough time to
charge a discharged set of batteries. If the
batteries are not fully discharged, charge for a
period of time that is proportionally less than what
is required for a fully discharged set of batteries,
ie: half discharged batteries need four to six hours
of charging time.
Do not expose the battery charger to water. Do
not touch uninsulated battery terminals or
unnecessarily expose any portion of your body to
the batteries when making electrical connections.
TO CHARGE BATTERIES
1. Stop the machine on a flat, dry surface next
to the charger and engage the machine
parking brake, if equipped.
FOR SAFETY: Before Leaving Or Servicing
Machine; Stop On Level Surface, Set Parking
Brake (If Equipped), And Turn Off Machine
And Remove Key.
2. Turn the key-operated on-off switch
counter-clockwise to stop the machine.
3. Lift open the machine hood, and tilt open the
rear cover.
WARNING: Batteries Emit Hydrogen Gas.
Explosion Or Fire Can Result. Keep Sparks
And Open Flame Away. Keep Covers Open
When Charging.
4. Check the electrolyte level in the batteries.
Before charging, add just enough distilled
water to cover the plates. Then, after
charging is completed, add enough water to
bring the level up to the indicator ring. If the
water level is topped off before charging,
normal expansion of the electrolyte may
cause an overflow, resulting in loss of acid
balance and damage to the machine.
