C. What Interlocks, Cut-Outs and Warnings Do I Have?
Operating Instructions To Check Interlocks, Cut-Outs and Warnings
1. Approaching Instability Warning Light and Alarm
The aerial lift is equipped with an "APPROACHING INSTABILITY" Warning Light and Alarm. When the alarm is "on" the aerial lift is in a potentially unsafe out-of-level or unstable position and all "boom" functions will be disabled. An unsafe out-of-level condition is defined as the boom being either raised or extended and the aerial lift is tilted at an angle greater than 5° from the front to the rear or from side to side.
The unsafe condition is indicated by a red warning light located on the top center of the aerial control station and an audible "dual-tone" alarm. When the "APPROACH-ING INSTABILITY" Warning Light and Alarm turn "on" the boom and jib boom, turret rotate, platform rotate and platform tilt functions will not operate. The drive and steer operations are not affected and will operate. Should the "APPROACHING INSTABILITY" Warning Light and Alarm come on, maneuver the aerial lift back in the direction it was previously driven from until it is once again on a safe level operating surface. When the "APPROACHING INSTABILITY" Warning Light and Alarm turn "off" all functions will be restored.

To Determine if Approaching Instability Warning Light and Alarm is Operational (Continued):
- a. Simple test of "APPROACHING INSTABILITY" Warning Light and Alarm: Red light is on and the audible alarm sounds when the tilt sensor goes beyond a 4.5° slope. By hand push the tilt sensor beyond 5° (can be determined by the level indicator on top of the tilt sensor); red light and alarm should turn on. Try operating a boom function from ground; boom function should not operate.
- b. Operational test of "APPROACHING INSTABILITY" Warning Light and Alarm:
Move the boom fully "in" (retract) and down (the stowed position).
With the drive speed select switch to "LOW", drive the aerial lift onto a slope slightly greater than 5° but not greater than 10°. Be sure the platform is pointed downthe slope. Drive the aerial lift partially up the slope and come to a complete stop. Release the foot operated switch. The "APPROACHING INSTA-BILITY" Warning Light and Alarm should turn "on". DO NOT operate the aerial lift if the alarm does not turn on.
If the alarm turns "on", step down on pedal of the foot operated switch (the alarm will turn off) and operate the "BOOM IN/ OUT" control lever to extend the boom out slightly. The alarm should turn "on" and the boom function should stop. DO NOT continued to operate the function if the alarm does not turn "on" or if the boom out function does not stop.

DO NOT STAND ON AERIAL LIFT WHILE UNLOADING BY ANY OF THESE PROCEDURES.
Unloading the Aerial Lift Under Its Own Power
ONLY TRAINED OPERATORS EXPERIENCED WITH THIS AERIAL LIFT'S CONTROLS ARE TO UNLOAD THE AERIAL LIFT.
- 1. Visually inspect aerial lift for any sign of damage, leaks or loose wires. If any problems are found, repairs must be made before unloading.
- 2. If unloading ramps are being used, select ramps of adequate capacity to support the weight of the aerial lift (see the "Specifications" Section of this manual).
Ramps should be wide enough to allow plenty of side clearance beyond the wheels (see "Specifications" Section of this manual).
Ramp angle must not exceed 11° (20%).
Unloading
Unloading the Aerial Lift Under Its Own Power (Continued)
3. It is suggested that the aerial lift be attached to a winch for the unloading procedure. Attach thewinch cable to the loops provided for this purpose on the front of the base. (see illustrations below). Using a winch will assure greater safety in unloading the aerial lift and limit the speed that it can descend the ramp.
NOTE: If the angle of the ramp exceeds 11° (20%), a winch must be used to unload the aerial lift.
4. Make sure the winch cable is properly attached to the aerial lift. Remove all tie downs and wheel chocks.
NOTE: If unloading from a "roll back" or "tilt back" truck, make sure the winch cable is properly attached and that all slack is out of the cable before raising the truck bed.

Unloading the Aerial Lift Under Its Own Power (Continued)
NOTE: When going up or down a grade the platform should always be pointed down the slope (counterweight end facing up slope) and with the boom centered over the non-steering wheels. Descend the slope in "increments". Allow the brakes to apply completely before once again operating the DRIVE/ STEER CONTROL LEVER. Do not permit the aerial lift to "free-wheel" (uncontrolled acceleration) down any grade.
- 5. Ensure the AERIAL/ GROUND Selector Switch is in the "AERIAL" position. Ensure Emergency Stop Switch is reset. Ensure Master Switch is "ON".
- 6. Enter the platform, secure the safety gate and attach the fall protection gear. Ensure Emergency Stop Switch is reset.
- 7. Select "SLOW" drive speed.
- 8. Straighten the wheels to allow direct travel down ramp.
NOTE: Platform and jib boom may need to be raised to allow for greater ground clearance.
- 10. Ensure the unloading aera is clear of personnel, debris and any other hazards.
- 11. Carefully drive the aerial lift off the truck or trailer with the assistance of the winch , if used. Drive at a controlled rate, moving the drive lever to the center "off" position momentarily to allow the brakes to slow the aerial lift. Keep the drive function engaged while winching, to avoid damaging the aerial lift.
- 12. When the aerial lift has been unloaded to level ground, shut down the aerial lift.
- 13. Remove the winch cable before attempting to move the aerial lift.
