8.8.3 Replacing the Locking Pawl Assembly Cables
Refer to the description of the Ladder Locking Pawl Assembly in para. 4.3.2 and Figure 4-16. Install the
cable (2) first by attaching one end to the Locking Pawl assembly at (10), threading the cable through the
Balancer Assembly (4) and the other end to the Locking Lever (1). Ensure the Locking Lever is down in
the unlocked position and pull the cable tight before attaching to the lever. The locking nuts should be at
the end of the threaded ferrule to allow maximum adjustment. Attach one end of cable (12) to the Locking
Pawl Assembly on Section 2 and thread as shown in Figure 4-16. Pull the cable as tight as possible and
attach at the cable attaching bracket on Section 2 (13).
The locking nuts should be at the end of the threaded ferrule to allow maximum adjustment.
8.8.4 Calibrating the Locking Pawl Assemblies
Before calibrating the Locking Pawl Assemblies ensure the three Ladder Sections are in alignment (refer
to para 8.9.1). It is important that the Locking Pawls on Section 2 engage the rungs of Section 3 at exactly
the same instant that the Pawls on Section 1 engage the rungs of Section 2.
With the ladder hydraulics, extend the ladder a minimum of the distance between two rungs. Move the
Locking Pawl Control Lever forward to allow the Locking Pawls to swing up under control of their springs.
Retract the ladder until a rung of Section 2 is approximately 1/4" from engaging the abutment on the face
of the Locking Pawls on Section 1 (see Figure 8-4, number 4).
