Wall Extruder (Frame Nailer Gen IV and Tables)
Once the rack ram clamp is activated, any remaining height gap is removed, and the carriage is
locked to the correct framing height.
The carriage clamp must be applied before attempting to fire the guns.
Please note that the fixed carriage is not adjustable.

Loading
When the Wall Extruder has been set to the required framing dimension, and the Carriage and
Trolley clamps have been applied, load the material to be nailed.
Only the top and bottom plates
are to be loaded at this point
. Ensure that the timber faces are hard up against guide fences, and
pushed back onto the trolleys, to ensure nailing is square. Once ready, tell the computer program
that the plates have been loaded; the progressors will then push the plates to the first stud nailing
position.
Note: Operator must ensure they are familiar with their companies individual loading/unloading
procedures before nailing is commenced.

Clamping and Firing Operation
The clamping and firing operations use a Two Hand No Tie Down (THNTD) pneumatic initiating
system, which ensures both hands of the operator are clear of the clamping operation and the guns
firing operation.
When the required framing components are correctly in place, the two-step clamping sequence can
begin.
-
The first clamping step is initiated by simultaneously holding down both
RED
firing buttons
(Figure 2, Items 1 and 2) until the plate clamps have been activated.
The Plate clamps hold down the outer frame and lock it in place vertically.
-
Load the required stud onto the Wall Extruder. Ensure that it is against the Stud Pins, and within
the range of the horizontal stud clamps, so that the frame will be square.
-
The next clamping step is to, again, simultaneously hold down both
RED
firing buttons (Figure 2,
Items 1 and 2) until the remaining clamps have been activated.
First the horizontal stud clamps come up from underneath the carriage plates and lock the studs in
place against the pins. Then the vertical stud clamps push down on the studs, locking them against
the carriage moving plate. The rack ram clamp then pushes the carriages into the frame, securing
the rack to the beam and horizontally clamping the frame. These clamps all come on one after the
after in the order described, so that they do not interfere with each other.
The guns will not fire if the clamp sensors are not activated. There are
three
types of clamp sensors
as shown in Figure 3.
-
The first type of sensor is on each of the carriage assemblies, and line up with the gun firing line
on the carriage moving plate. These sensors confirm whether there are plates on both carriages,
and that they are in the correct position. The plate sits above the sensor, and the sensor is
activated by depression when the plate is pushed down by the plate clamp. If a plate has not
been added, the sensor will not be depressed, and will not activate. If the plates are not in the
correct position, the sensor will not be depressed, and will not activate.
-
The second type of sensor is located within the vertical stud clamp cylinders, one on each
carriage, and confirms that the stud has been loaded and clamped correctly. If there is no stud
