II. INSTALLING THE LADDER ACCESS SYSTEM
A. PreparationforMounting
The System has been tested at the factory prior to shipping. No additional adjustments should be
cut down in length for your application. A can of touch-up paint is available for this purpose. See

When the ladder is raised and lowered in this position, it should clear protruding objects on the
apparatus, such as emergency light, hand rails, etc. Make sure that when the ladders are in the up position
they do not obstruct cross lays on hose reels.
In the event that the booms come into contact with the stiffening rib at the top of the vertical hose bed
wall, you may have to notch out the stiffening rib to recess the HLAS System. If the stiffening rib must be
notched, the exposed metal surfaces should be painted and covered with an edge guard material. In
addition, if the stiffening rib is notched, you may wish to add a backing plate on the inside surface of the
hose bed wall. The plate will reinforce the hose bed wall and provide a good mounting support for the
vertical mounting holes, if used. The edges of the mounting plate should be rounded off on the side next

A mechanism for opening the door panel in front of the unit must also be fabricated by the apparatus
manufacturer. The actual mechanism will depend on whether the door opens down or to the side. Contact

this method is superior to crimp connections. We further recommend that a terminal block or quick

holes in the apparatus.

The ladder guard kit contains one tube of epoxy and two stainless steel guards. The guards may be

The small plastic sleeves may be purchased directly from the ladder manufacturer. The sleeves are
pop-riveted to the rungs and prevent unnecessary wear on the rungs from constant rubbing on the side rails.

VI. TROUBLESHOOTING
should be required unless excess movement is noted.
A. ExcessMovementoftheRackandLadders
If the rack and ladders appear to be moving more than when the System was initially installed, it is
probably due to one of the following reasons:
1. Ladders and rack not properly seated against the vehicle mounted ladder stop.
A ladder stop must be provided by the apparatus manufacturer to prevent the ladders from
swaying. If the ladder rack is not touching the stop, swaying will occur. Shims may be required to
close the gap.
2. Booms move freely when the rack is pushed or pulled by hand.
