Wall Extruder (Frame Nailer Gen IV and Tables)
-
Ensure that the gun mounts on the carriage assemblies are still correctly positioned.
The rack ram cylinder and rack should also be generally maintained every month to check on the
condition of the cylinder and the clamping mechanism.
All assembly components should also be checked to ensure there is no damage or wear that will
affect the performance of the assemblies. Ensure that there are no loose, damaged, or missing bolts,
and replace or tighten as necessary.
Do not use the Wall Extruder if the floating carriage assembly is not adjusting correctly and/or still
allows movement when locked; if the Pneumatic brake switch and/or the carriage clamp are not
activating correctly; if any of the gun mounts on either of the carriage assemblies is not firing
straight/is blocked; or if any timber added does not fit onto an assembly/does not sit square; and if
any of the above cannot be fixed by general maintenance.
11.1.14
Loose Fasteners and Fixings
Check for loose, missing, or damaged bolts especially on guards, cover and floor fixing. Tighten or
replace where necessary.
11.1.15
Guide Trolley Slides
The sliders on the Guide Trolleys should allow the trolleys to move up and down the Fence smoothly
and easily. Check the slides for excessive play and/or wear and tighten/replace if necessary. Use the
guide in section 11.2 to replace the sliders, or alternatively contact Spida Machinery.
11.1.16
Bench Top
Check the table bench tops for excessive wear or damage and replace if necessary. This should be
checked every six months.

Maintain Brake Materials
Check brake materials for wear and replace as necessary.
-
On the Nog trolleys, check the rubber stop at the end of, and clamp pad adjacent to, each clamp
arm.
-
On the floating carriage, check the carriage clamp and rack connections.
11.1.18
Maintain Wall Extruder
Check all major operating components for wear, fatigue, and fixing. Adjust, tighten, or replace
components as required.
Do not use the Wall Extruder if it is damaged significantly or if it is not working correctly, and all
other mentioned maintenance is not applicable.
11.1.19
Nail Guns
Nail guns have been fitted to the Wall Extruder to provide accurate and reliable nailing. All
maintenance/servicing that is required, should be carried out as specified by the gun supplier’s
handbook.
Periodically check the distances between guns, on each carriage assembly, to ensure that the correct
nailing distance is maintained. If any shift has occurred, then adjust guns as required.
Also, be sure to check the gun mount assemblies for potential damage. If any damage is apparent
then do not use the Wall Extruder, and contact a supervisor, supplier, or maintenance engineer.
