3 Insert the hook assembly into the beam assembly and align "T" pin with the slot in the beam. Gently
apply pressure to both the hook and the insertion tool in a manner which allows the "T" to pass through
the slot in the beam and penetrate into the slot in
the insertion tool.
4 Rotate the tool 90 degrees. The "T" should now
be perpendicular to the slot. Make certain the "T"
is resting in the grooves on the top of the beam.
The hook should point toward the MP4 or the
operator.
5 The hooks for the B1000 beam screw onto the
bottom of the hook shaft as shown in figure 3-2.
Note that the hook swings parallel to the beam
with relatively little force but resists movement
perpendicular to the length of the beam.
6 Remove the tool and store it properly in the hole
provided on the base- plate. Bent beams will not
measure properly and are not covered under
warranty. Hooks are difficult to install without
the tool.
7 Insert a device in the appropriate device holder.
Do not place the device holder under the hook at
this time.
Installing the Rotatable Hook - B100R Beam
WARNING: Set the POWER switch to OFF.
1 Pull the beam access cover forward. Select the proper hook. Many specifications require that the Hook
diameter be approximately 2.5 times the bond wire diameter.
NOTE: The shaft and knob assembly should not be in position while installing the rotatable hook
assembly.
2 Insert the hook assembly into the beam assembly and align "T" pin with the slot in the beam (see figure
3-3). Gently apply pressure to both the hook and the insertion tool in a manner which allows the "T" to
pass through the slot in the beam and penetrate into the slot in the insertion tool.
3 Rotate the tool 90 degrees. The "T" should now be perpendicular to the slot. Make certain the "T" is
resting in the grooves on the top of the beam. The hook should point toward the MP4 or the operator.
4 With the “T” handle installation tool, pick up the “T” handle by its handle and carefully slip it onto the
hex bushing affixed to the top of the rotatable hook.
5 Rotate the “T” handle gently until it falls into place. Release the installation tool and carefully rotate the
“T” handle until the handles are positioned parallel to the beam.
