3.9 SERVICE HYDRAULIC OIL
The machine is shipped with hydraulic oil in the reservoir. Run the machine for
approximately 15 minutes to allow any extra air to purge out of the hydraulic
system. Check hydraulic reservoir and if necessary fill the reservoir to the
appropriate level with Mobil 1 15W-50 synthetic motor oil. 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.
4. OPERATION INSTRUCTIONS
4.1 CONTROLS
4.1.1 Familiarize yourself with all controls before operating the mower.
4.1.2 Motion Control Levers: Located on each side of the console.
The left lever controls the flow of hydraulic oil from the left hydrostatic pump to
the left drive wheel motor. The right lever controls the flow of hydraulic oil from
the right hydrostatic pump to the right drive wheel motor.
IMPORTANT: To begin movement (forward or backward) the operator must
be in the seat, the brake lever must be disengaged (pushed down) before
the motion control levers can be moved in or the engine will kill.
When levers are centered in the T-slot the drive system is in the neutral position.
With levers moved out in the T-slot the drive system is in the neutral lock
position (See Figure 4).
FIGURE 4
MOTION CONTROL POSITIONS
By moving both levers an equal amount forward or back from the neutral position the
machine can be caused to move forward or backward in a straight line.
Movement of the left lever forward will cause the left drive wheel to rotate in a
forward direction. Movement of the right lever forward will cause the right
drive wheel to rotate in a forward direction. To stop forward travel, pull the
levers back to the neutral position.
To turn left while moving forward, move the left lever back toward neutral to
slow the left drive wheel. To turn right while moving forward, move the right
lever back toward neutral to slow the right drive wheel.
To make a zero turn to the left, pull the left lever back beyond neutral while
holding the right lever slightly ahead of neutral.
To make a zero turn to the right, pull the right lever back beyond neutral while
holding the left lever slightly ahead of neutral.
