3.9 SERVICE HYDRAULIC OIL
The machine is shipped with hydraulic oil filled to the top of the baffle in 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.
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 Fig 3).
FIG. 3
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 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 the neutral
position while holding the left lever slightly ahead of the neutral position.
Pulling the levers back from the neutral position will cause the respective drive
wheels to rotate in a reverse direction (spring tension can be felt when moving
into reverse from neutral).
To turn to the left while backing, move the left lever forward toward neutral. To
turn to the right while backing, move the right lever forward toward neutral.
