Assembly Instructions
To fill (activate) battery with electrolyte (if battery has
been shipped dry):
1. Remove the battery hold-down bar, disconnect
the battery cables and lift the battery out of the
tray.
IMPORTANT: Battery must be removed from
the mower before filling with electrolyte.
IMPORTANT:
grade sulfuric acid electrolyte with a 1.265 spe­
cific gravity to activate the battery. DO NOT use
water or any other liquid during initial activation.
2. Remove the filler caps and carefully fill each cell
until the electrolyte is just above the plates.
3. After the battery is filled with electrolyte, replace
the filler caps and charge the battery. Refer to

Battery Charging.

Battery Charging
BATTERIES PRODUCE EXPLOSIVE GASES
Charge the battery in a well-ventilated
●
area, so that gases produced while
charging can dissipate.
● Keep sparks, flames, and smoking ma-
terials away from the battery at all
times.
● Make sure the battery cap vents are
open after the battery is filled with acid
(check manifold vent on each cap).
● Make sure the battery charger is un-
plugged before connecting or discon-
necting cables to the battery.
1. Charge the battery at 15 amps for 10 minutes.
DO NOT exceed 20 amps maximum recom­
mended charging rate. Charge until specific
gravity is at least 1.250. Total charging time
should not exceed one (1) hour.
2. After charging the battery, adjust the electrolyte
level to the bottom of the vent wells [1/4 to 1/2 in.
(6 to 13 mm) above the plates].
Obtain and use only battery
DANGER
IMPORTANT: DO NOT overfill the battery.
Electrolyte will overflow through the vented
caps onto parts of the machine and WILL result
in severe corrosion.
3. Install battery.

Battery Installation

IMPORTANT: Make sure battery is securely mount­
ed in the frame. A loose battery may cause damage
to the case resulting in acid leakage and severe
damage to the machine. A hazard may be created
by damage to critical working parts and safety sys­
tems.
Install the battery in the mower as shown in Battery
Installation photo. Connect the positive (+) first and
then the negative (-) cable to the proper battery ter­
minal [red cable and boot connects to the Posi-
tive (+) terminal]. Slide the rubber boot up and over
the battery post, making sure it covers the post com­
pletely to prevent an electrical short.
WARNING
Make sure the battery cap vents are open.
Improper venting of the battery COULD
cause a battery explosion.
