Set Up Instructions
Activate the Battery
Bulk electrolyte with 1.260 specific gravity must be
purchased from a local battery supply outlet.
1. Remove the battery from the tractor: refer to
Operator’s Manual, Removing the Battery.
IMPORTANT: Be careful not to damage the
long vent tube when removing the battery
box.
POTENTIAL HAZARD
• Battery electrolyte contains sulfuric acid
which is a deadly poison and it causes
severe burns.
WHAT CAN HAPPEN
• If you carelessly drink electrolyte you could
die or if it gets onto your skin you will be
burned.

battery charger to the battery posts (Fig. 6).
Charge the battery at a rate of 4 amperes or less
for 4 hours (12 volts).

HOW TO AVOID THE HAZARD
• Do not drink electrolyte and avoid contact
with skin, eyes or clothing. Wear safety
glasses to shield your eyes and rubber
gloves to protect your hands.
• Fill the battery where clean water is always
available for flushing the skin.
• Follow all instructions and comply with all
safety messages on the electrolyte container.
2. Remove filler caps from the battery. Slowly pour
electrolyte into each cell until the electrolyte
level is up to the lower part of the tube (Fig. 5).

Check Safety System
Set Up instructions
POTENTIAL HAZARD
• Charging battery produces gasses.
WHAT CAN HAPPEN
• Battery gasses can explode.
HOW TO AVOID THE HAZARD
• Keep cigarettes, sparks and flames away
from battery.
4. When the battery is fully charged, disconnect the
charger from the electrical outlet then from the
negative and positive battery posts (Fig. 6).
5. Slowly pour electrolyte into each cell until the
level is once again up to the “UPPER” line on
the battery case (Fig. 5) and install covers.
6. Install the battery in the tractor and connect
cables with (2) 1/4 x 3/4” bolts and (2) 1/4”
plastic wing nuts: refer to the Operator’s
Manual, Installing the Battery.
Refer to the Operator’s Manual, Checking Safety
System.
Electric Clutch Break-In
The electric clutch requires initial break-in to seat the
mating surfaces. Engage/disengage the clutch 10-20
cycles with the mower installed. Rotating the blades
provides load for break-in.
Adjust Electric Clutch
The electric clutch has three (3) adjustment nuts that
all must be adjusted the same (Fig. 7).
1. Insert a 0.010 inch (.25 mm) feeler gauge into
the slot (Fig. 7).
2. Turn the nut until light resistance is felt on the
gauge.
Crankcase Oil
Check the engine oil level, refer to the Operator’s
Manual, Engine Oi. If necessary, add only enough oil
to raise the level to the “FULL” mark on the dipstick.
Note: Slide the oil dipstick fully into the
filler tube, do not thread onto fill tube.
Lubricate the Tractor
Refer to the Operator’s Manual, Greasing and
Lubrication.
If equipped with Power Lift, check reservoir level, fill
with Dexron Type II.
3. Repeat for all three adjusting nuts.
