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.
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. Deploy the Outriggers, this is done from the lower control panel, use the “auto level” button along with
the analog rocker to lower all four outriggers at the same time, an audible warning will sound until the
outriggers are fully deployed and the machine is level, ensure that all four individual outrigger lights are
illuminated. Fine tuning of the chassis inclination can be achieved by holding each individual outrigger
button and using the analog rocker. (ref: chassis controls illustration on page 5)
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. Test each machine function (Lift, Slew, Telescope) from the lower control station by pressing and holding
the desired function button then moving the Analog Rocker to the Up or Down position (ref: chassis con-
trols illustration on page 5)
7. Open the Emergency Lowering Valve (see Figure 4) by pulling the knob out to check for proper opera-
tion. When the platform is lowered, release the knob.
8. Push the Chassis Emergency Stop Switch to check for proper operation. All machine functions should
be disabled. Twist the Chassis Emergency Stop Switch to resume.
9. Climb onto the cage.
10. Check that the route is clear of obstacles (persons, obstructions, debris), is level, and is capable of sup-
porting the outrigger loads.
11. Mount the platform and properly close the drop bar.
12. Test each machine function (Lift, Slew, Telescope, Platform Rotate, Cage Level) from the upper control
station by pressing the desired function button then moving the Joystick to the Forward or Back position
(ref: platform controls illustration on page 5)
13. Push the Platform Emergency Stop Switch to check for proper operation. All machine functions should
be disabled. Pull out the Platform Emergency Stop Switch to resume.
