    Curbilder Operating Instructions A. Preparing machine for operation Spray with water when extruding concrete curb.

    C. General considerations Optimum compaction has been designed into the Curbilder and the curb form. Greater compaction will be obtained when the machine is operating uphill, or by raising the front wheel assemblies, transferring weight to the curb form. Lowering the front wheel assemblies decreases compaction by decreasing the weight carried on the curb form.

  • Page 13 Compaction tube The compaction tube must be inspected regularly and kept clean and free of holes. For holes, steel patches can be welded on the inside of the compaction tube and ground smooth to maintain proper auger clearance. When the compaction tube is damaged or worn beyond repair, a new compaction tube should be purchased.
  • Page 14 in a very short period of time. The worn auger end will look pointed like a corkscrew. At this point, the mix and/or the curb form need to be evaluated. HARD FACING INSTRUCTIONS Welding repair procedure: Two layers of weld for maximum wear. Weld as cold (Low Heat) as possible to prevent dilution of hard surfacing with base metal.
