and green/white wire to the negative battery
terminal. Slip insulator boot over the positive
terminal.

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.
