Secton 10 - Mantenance
Semi-annual Maintenance
The following maintenance should be done every 6 months or 500 hours of operation.
1) Test the Platform Overload System
Testing the platform overload system regularly is essential to safe machine operation. Continued
use of an improperly operating platform overload system could result in the system not sensing an
overloaded platform condition. Machine stability could be compromised resulting in the machine
tipping over.
Perform this procedure with the machine on a firm, level surface�����
Turn the key switch to platform control. Pull out the ground red Emergency Stop button to the
ON position. Turn the platform red Emergency Stop button clockwise to the ON position.
Determine the maximum platform capacity.
Using a suitable lifting device, place an appropriate test weight equal to the maximum platform
capacity in the center of the platform floor.
Result:
The overload alarm at the platform controls should not sound, indicating a normal
condition.
Result:
The overload alarm at the platform controls sounds. Calibrate the platform overload
system.
Add an additional weight to the platform not to exceed 25% of the maximum rated load.
Result:
The overload alarm at the platform controls sounds, indicating a normal condition.
Result:
The overload alarm at the platform controls does not sound. Calibrate the platform
overload system.
Test all machine functions from the platform controls.
Result:
All platform control functions should not operate.
Turn the key switch to ground control.
Test all machine functions from the ground controls
Result:
All ground control functions should not operate.
Lift the test weight off the platform floor using a suitable lifting device.
Result:
The overload alarm at the platform controls should not sound, indicating a normal
condition.
Result:
The overload alarm at the platform controls sounds. Calibrate the platform overload
system.
Test all machine functions from the ground controls.
Result:
All ground control functions should operate.
Turn the key switch to platform control.
Test all machine functions from the platform controls.
Result:
All platform control functions should operate.
