D-3 Replace the Drive Hub Oil
• Tools will be required to perform this procedure.
• New parts will be required to perform this procedure.
• Dealer service will be required to perform this procedure
Replacing the drive hub oil is essential for good machine performance and service life. Failure to
replace the drive hub oil at yearly intervals may cause the machine to perform poorly and continued
use may cause component damage.
1. Select the drive hub to be serviced. Drive the machine until one
of the two plugs is at the lowest point.
2. Remove both plugs and drain the oil into a suitable container.
3. Drive the machine until one of the two plugs is at the highest
point.
4. Fill the hub until the oil level is even with the bottom of the lowest
plug hole.
5. Install the plugs into the drive hub.
6. Repeat this procedure for each drive hub.

D-4 Test the Drive Brakes
• Tools will be required to perform this procedure.
Proper brake action is essential to safe machine operation. The drive brake function should operate
smoothly, free of hesitation, jerking and unusual noise. Hydraulically-released individual wheel brakes
can appear to operate normally when not fully operational.
Perform this procedure with the machine on a firm level surface that is free of obstructions, with the
platform extension deck fully retracted and the platform in the stowed position.
1. Mark a test line on the ground for reference.
2. Start the engine from platform controls.
3. Choose a point on the machine; i.e., contact patch of a tire, as a visual reference for use when
crossing the test line.
4. Slowly move the joystick in the direction indicated by the blue arrow on the control panel until the
machine begins to move, then return the joystick to the center position.
• Result:
The machine should move in the direction that the blue arrow points on the control
panel, then come to a quick stop.
5. Slowly move the joystick in the direction indicated by the yellow arrow on the control panel until
the machine begins to move, then return the joystick to the center position.
• Result:
The machine should move in the direction that the yellow arrow points on the control
panel, then come to a quick stop.
6. Bring the machine to maximum drive speed before reaching the start line. Release the function
enable switch on the joystick or release the joystick when your reference point on the machine
crosses the test line.
7. Measure the distance between the test line and your machine reference point.
