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: Obtain and use only battery
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
IMPORTANT: On MTEFI and MTLEFI models, al-
ways disconnect the negative (-) battery terminal be-
fore charging. Failure to do so can result in damage
to the ECU.
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].
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.
DANGER
Battery electrolyte is a poisonous and cor-
rosive sulfuric acid solution.
•
Avoid spillage and contact with skin,
eyes, and clothing - causes severe burns.
•
To prevent accidents, wear safety gog-
gles and rubber gloves when working with
electrolyte.
•
Neutralize acid spills with baking soda
and water solution.
DANGER
BATTERIES PRODUCE EXPLOSIVE GASES
•
Charge the battery in a well-ventilated
area, so that gases produced while charg-
ing can dissipate.
•
Keep sparks, flames, and smoking mate-
rials 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 unplug-
ged before connecting or disconnecting
cables to the battery.
