Section 6 - Maintenance
B-5 Test the Emergency Stop
A properly functioning Emergency Stop is essential for safe machine operation. An improperly
operating red Emergency Stop button will fail to shut off power and stop all machine functions,
resulting in a hazardous situation.
As a safety feature, selecting and operating the ground controls will override the platform controls,
except the platform red Emergency Stop button.
1. Start the engine from ground controls.
2.
Push in the red Emergency Stop button at the ground controls to the off position.
• Result:
The engine should shut off and no machine functions should operate.
3. Start the engine from platform controls.
4.
Push in the red Emergency Stop button to the off position.
• Result:
The engine should shut off and no machine functions should operate.
Note:
The red Emergency Stop button at the ground controls will stop all machine operation, even if
the key switch is switched to platform control.
B-6 Test the Key Switch
Proper key switch action and response is essential to safe machine operation. The machine can be
operated from the ground or platform controls and the activation of one or the other is accomplished
with the key switch. Failure of the key switch to activate the appropriate control panel could cause a
hazardous operating situation.
Perform this procedure from the ground using the platform controls. Do not stand in the platform.
1. Turn the ground red Emergency Stop button clockwise to the on position. Pull out the platform
red Emergency Stop button to the on position.
2. Turn the key switch to ground controls and start the engine from ground controls.
3. Check any machine function from the platform controls.
• Result:
The machine functions should not operate.
4. Turn the key switch to platform controls and start the engine from platform controls.
5. Check the machine functions from the ground controls.
• Result:
The machine functions should not operate.
6.
Turn the key switch to the off position.
• Result:
The engine should stop and no functions should operate.
B-7 Test the Automotive-style 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. Start the engine from platform controls.
2. Push down the horn button at the platform controls.
• Result:
The horn should sound.
