Mid-Mount Ascendant Aerial Tower / 4-15
OPERATION
4-4.3
Primary Operation
1. Deploy the turntable access ladder and ascend to the turntable platform using the three points of contact
method.
2. Safely position yourself on the turntable operating platform.
3. Pull the control console toward operator until it is fully deployed and locks down.
4. Open the control console cover.
5. Ensure that the waterway is either drained or that the discharge valve at the monitor is open to allow the
waterway to extend or retract freely without stressing the seals.
6. Activate the LADDER ILLUMINATION lights
(if equipped)
.
7. Activate scene lighting or obtain scene lighting from another source or apparatus so that the operating scene is
illuminated sufficiently for hazards within the operating area to be identified.
8. Determine the wind speed and ensure that it does not exceed the maximum allowable wind speed (see load
chart).
9. Consider the following conditions and determine if the load chart provided at the console is applicable, or if an
alternate chart is required or if the chart values need to be adjusted. Monitor these conditions continually during
operation and adjust your aerial device loading accordingly.
— Wind speed
— Icing conditions
— Short-Jack configuration
— Apparatus set-up angle (green or yellow zone on the apparatus angle indicators)
10. Identify any obstructions in the area and plan how you will move the aerial device to avoid obstructions and
maintain safe distance from power lines.
11. Order any personnel on the turntable to move away and stay away from the ladder and other parts that will move
when the aerial device moves.
12. Communicate with spotters to be sure that there are no hazards that are not visible to you.
13. Shout out to spotters and personnel in the area that you intend to move the aerial device.
NOTE:
Only raise aerial enough to lift out of the boom support and enough to safely extend the aerial.
14. Operate the elevation control (RAISE) to lift the aerial device slightly and enough to clear the boom support.
15. Operate the extend/retract control (EXTEND) to clear the back of the aerial from the cab rear wall.
NOTE:
The aerial can not be rotated until the aerial is raised enough to clear the boom support and the
truck body and is also extended enough to clear the rear wall of the cab.
16. Operate the raise/lower, extend/retract, and rotate (right/left) controls as required to move the aerial device to
the desired position.
17. Approach the ground or any structure slowly and carefully, stopping motion before you make contact. Your aerial
may make contact with the ground or structures if the weight of loading causes it to settle into contact. Your
device is not designed for reverse loading and you should never power your device into the ground or onto a
structure.
Raising the Aerial too far without extending the ladder will result in the back of the aerial contacting the
back of the cab, causing damage to equipment.
