STAND CLEAR of the work platform while performing the following checks.
Before operating the work platform, survey the work area for surface hazards such as holes, drop-offs,
bumps and debris.
Check in ALL directions, including above the work platform, for obstructions and electrical conductors.
Protect the control console cable from possible damage while performing checks.
1. Move the machine, if necessary, to an unobstructed area to allow for full elevation.
2. Pull Chassis Emergency Stop Switch to the ON position.
3. Pull Platform Emergency Stop Switch to the ON position.
4. Turn and hold the Chassis Key Switch to CHASSIS. Push the Chassis Lift/Lower Switch to the UP posi-
tion and raise the platform approximately 2,1 m (7 feet). BLOCK THE ELEVATING ASSEMBLY AS
DESCRIBED ON PAGE 9.
5. Visually inspect the elevating assembly, lift cylinder, cables, and hoses for cracked welds and structural
damage, loose hardware, hydraulic leaks, loose wire connections, and erratic operation. Check for miss-
ing or loose parts.
6. Verify that the Depression Mechanism Supports have rotated into position under the machine. REMOVE
THE SCISSOR BRACE AS DESCRIBED ON page 14.
7. Turn and hold the Chassis Key Switch to CHASSIS. Push the Chassis Lift/Lower Switch to the UP posi-
tion and fully elevate the platform.
8. Partially lower the platform by pushing Chassis Lift/Lower Switch to LOWER, and check for proper oper-
ation of the audible lowering alarm.
9. Open the Emergency Lowering Valve (see Figure 5) by pulling the knob out to check for proper opera-
tion. When the platform is lowered, release the knob.
10. Push the Chassis Emergency Stop Switch to check for proper operation. All machine functions should
be disabled. Pull out the Chassis Emergency Stop Switch to resume.
11. Turn the Chassis Key Switch to DECK.
12. Check that the route is clear of obstacles (persons, obstructions, holes, and drop-offs, bumps and
debris), is level, and is capable of supporting the wheel loads.
13. Mount the platform and properly close the entrance.
14. Turn the Drive/Lift Switch to DRIVE.
NOTE: Use both HI and LOW drive (if applicable) when performing the following step.
15. While engaging the Interlock Switch, move the Control Handle to FORWARD, then REVERSE, to check
for speed control.
16. Push the Steering Switch RIGHT, then LEFT, to check for steering control.
17. Turn the Drive/Lift Switch to LIFT. Grasp the Control Handle, engaging the Interlock Switch, and push it
forward to check platform lift controls. Raise the platform to full elevation.
