Section 10 - Maintenance
5. Check the machine functions from the platform controls.
• Result: The machine functions should not operate.
6. Turn the key switch to the Off position (pushed in).
• Result: No function should operate.
Horn
The horn is activated at the platform controls and sounds at the ground as a warning to ground
personnel. An improperly functioning horn will prevent the operator from alerting ground personnel of
hazards or unsafe conditions.
1. Turn the key switch to platform control and pull the red Emergency Stop button out to the On
position (pulled out) at both the ground and platform controls.
2. Push down the horn button at the platform controls.
• Result: The horn should sound.
Drive Brake
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. Turn the key switch to platform control and pull the red Emergency Stop button out to the On
position (pulled out) at both the ground and platform controls.
3. Press the drive function select button.
4. Choose a point on the machine; i.e., contact patch of a tire, as a visual reference for use when
crossing the test line.
5. Bring the machine to top drive speed before reaching the test line. Release the function enable
switch or the joystick when your reference point on the machine crosses the test line.
6. Measure the distance between the test line and your machine reference point.
• The maximum braking distance at high speed on a paved surface is 24 inches±11.8
inches (61 centimeters±30 centimeters)
Result: The machine stops within the specified braking distance. No action required.
•
Result: The machine does not stop within the specified braking distance.
•
Note: The brakes must be able to hold the machine on any slope it is able to climb.
7. Replace the brakes and repeat this procedure beginning with step 1.
Drive Speed, Lowered Platform
Proper drive functions are essential to safe machine operation. The drive function should respond
quickly and smoothly to operator control. Drive performance should also be free of hesitation, jerking
and unusual noise over the entire proportionally controlled speed range.
Perform this procedure with the machine on a firm, level surface that is free of obstructions.
