Electrocution/explosion hazard.
Contact with electrically charged circuits could
result in death or serious injury. Remove all
rings, watches and other jewelry.
1. Inspect the underside of the chassis for
damaged or missing ground strap(s).
2. Inspect the following areas for burnt,
chafed, corroded and loose wires:
• Inside ground control panel wires
• Hydraulic power unit module tray wires
• Battery tray(s) wires
• Platform control wires
3. Turn the key switch to ground control and
pull out the red Emergency Stop button to
the on position at both the ground and
platform controls.
4. Raise the platform approximately 8 feet /
2.5 m from the ground.
5. Rotate the safety arm away from the
machine and let it hang down.
6. Lower the platform onto the safety arm.
Crushing hazard.
Keep hands clear of the safety arm when
lowering the platform.
7. Inspect the center chassis area and
scissor arms for burnt, chafed and
pinched cables.
8. Inspect the following areas for burnt,
chafed, corroded, pinched and loose
wires:
• Scissor arms wires
• ECU to platform controls wires
• Power to platform wires
9. Inspect the insulating oil coating at the
following position:
•
The link between the ECU and wiring

Inspect the Tires and Wheels
This procedure should be performed every
250 hours or quarterly, whichever comes first.
Maintaining the tires and wheels in good
condition is essential to safe operation and
good performance. Tire and/or wheel failure
could result in a machine tip-over. Component
damage may also result if problems are not
discovered and repaired in a timely fashion.
1. Check the tire surface and sidewalls for
cuts, cracks, punctures and unusual
wear.
2. Check each wheel for damage, bends and
cracks.
3. Remove the cotter pin and check the
castle nut for proper torque.
Note: Always replace the cotter pin with a new
one when removing the castle nut or when
checking the torque of the castle nut.
4. Install a new cotter pin. Bend the cotter
pin to lock in place.
Non-lubricated nut torque 406.7Nm
Lubricated nut torque 305Nm

Test the Emergency Stop
This procedure should be performed every
250 hours or quarterly, whichever comes first.
A properly functioning Emergency Stop button
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. Turn the key switch to ground control and
pull out the red Emergency Stop button to
the on position at both the ground and
platform controls.
2. Push in the red Emergency Stop button at
the ground controls to the off position.
