injury.
HOW TO AVOID THE HAZARD
♦Keep sparks, flames, or cigarettes away from
battery.
♦Ventilate when charging or using battery in an
enclosed space.
♦Make sure venting path of battery is always
open once battery is filled with acid.
2. Check the voltage of the battery with a digital
voltmeter. Locate the voltage reading of the
battery in the table below and charge the battery
for the recommended time interval to bring the
charge up to a full charge of 12.6 volts or
greater.
IMPORTANT: Make sure the negative battery
cables are disconnected and the battery charger
used for charging the battery has an output of 16

CAUTION
POTENTIAL HAZARD
♦If the ignition is in the “ON” position there is
potential for sparks and engagement of
components.
WHAT CAN HAPPEN
♦Sparks could cause an explosion or moving
parts could accidentally engage causing
personal injury.
HOW TO AVOID THE HAZARD
♦Be sure ignition switch is in the “OFF” position
before charging the battery.
3. Connect the negative battery cables.
NOTE: If the positive cable is also disconnected,
connect the positive (red) cable to the positive
battery terminal first, then the negative (black) cable
and green/white wire to the negative battery
terminal. Slip insulator boot over the positive
terminal.
NOTE: If time does not permit charging the
battery, or if charging equipment is not available,
connect the negative battery cables and run the
vehicle continuously for 20 to 30 minutes to
sufficiently charge the battery.
Installing Drive Wheels
1. Mount drive wheels with the valve stem to the
outside of the unit. Secure using four (4) 1/2-20
wheel nuts installed on studs in hubs for each
wheel. Torque to 95 ft-lbs (128 N-m).
Checking Tire Air Pressure
1. Check the air pressure in the drive tires. Proper
inflation for drive tires is 15 psi (103 kPa). Adjust
if necessary.
2. The mower deck casters and rear caster tires
are semi-pneumatic. No adjustment is
necessary.
Servicing the Engine
Refer to Engine Owner’s Manual.
Servicing the Hydraulic Oil
The machine is shipped with hydraulic oil in the
reservoir.
1. Run the machine for approximately 15 minutes
to allow any extra air to purge out of the
hydraulic system.
2. Check hydraulic reservoir and if necessary fill
the reservoir to the appropriate level with Mobil 1
15W-50 synthetic motor oil.
3. Replace hydraulic reservoir cap and tighten until
snug. Do not overtighten.
NOTE: The baffle is labeled “HOT” and “COLD”.
The oil level varies with the temperature of the oil.
The “HOT” level shows the level of oil when it is at
225°F (107°C). The “COLD” level shows the level of
the oil when it is at 75°F (24°C). Fill to the
appropriate level depending upon the temperature of
the oil. For example: If the oil is about 150° F
(65°C). Fill to halfway between the “HOT” and
“COLD” levels. If the oil is at room temperature
(about 75° F (24°C)), fill only to the “COLD” level.
