BATTERY CHARGING
The machine batteries are specially made for this
machine application. They are unique in that they
hold their power for long periods of time, but they
can only be recharged a certain number of times.
To get the most life from the batteries, charge
them when 25% of their charge is left.
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 (For machines below
serial number 003860)
Ten to twelve hours is generally enough time to
charge a discharged set of standard, 220 A/h
batteries. Fourteen to sixteen hours is generally
enough time to charge a set of heavy duty,
305 A/h batteries. If the batteries are not fully
discharged, set the timer for a period of time that
is proportionally less than what is required for a
fully discharged set of batteries, ie: half
discharged heavy duty batteries need seven to
eight hours of charging time.
1. Stop the machine on a flat, dry surface next
to an electrical outlet and set the parking
brake.
2. Turn the key-operated on-off switch
counterclockwise.
FOR SAFETY: Before Leaving Or
Servicing Machine; Stop On Level
Surface, Set Parking Brake, And Turn
Off Machine.
3. Open the seat support.
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 electrolyte up to the indicator
mark. 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 acid damage to
the machine area around the batteries.
5. Plug the battery charger cord into a wall
outlet.
6. Turn the battery charger knob to the number
of hours you wish to charge the batteries.
The charger gauge will indicate the charger
is operating.

timer reads “off” or the battery specific
gravity is 1.265.

9. Unplug the battery charger from the wall
outlet.
10. Check the electrolyte level of the batteries; it
should be up to the indicator mark.
