D. Curbilder is now in position to extrude curb.
 Start engine and idle five (5) minutes. When ready to extrude curbing, increase
engine speed to full throttle (3,000 RPM) to engage automatic clutch, thereby
driving the extrusion auger. DO NOT RUN CURBILDER AT PARTIAL THROTTLE
OR DAMAGE TO CENTRIFUGAL CLUTCH WILL RESULT.
 Fill hopper slowly with curb mix and allow curb form to fill. Feed Hopper of
Curbilder with asphalt using wheelbarrows or Curbloader. Feed Hopper of
Curbilder directly from concrete truck using discharge chute.
 As material nears the discharge end of the curb form, block the opening in order
that the material will be compacted. (A piece of wood or a flat shovel work well.)
 The Curbilder starts moving forward as material is extruded through the curb form.
THE FORCE OF EXTRUSION PROVIDES PROPELLING POWER.
 After Curbilder moves forward, the curb may be struck off with a shovel at the
desired starting point. (This excess material may be reused in the Curbilder). If
advanced start is not possible, starting end of curb may be hand shaped with
finishing trowel.
 Fill hopper with curb mix at a steady rate. It is best to operate the Curbilder at a
steady rate with as few of stops/starts as possible.
 Steer Curbilder keeping the pointer on the chalk line/string.
 Optimum compaction has been designed into the Curbilder and the curb form.
Greater compaction will be obtained when the machine is operating uphill, when
the brake is applied, 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.
 When the Curbilder is not extruding material, throttle engine down to disengage
automatic clutch so the auger stops turning and machine vibration does not break
apart curb.
 Never allow material to stand in the hopper when the Curbilder is not in operation.
Finish out the material in the hopper, raise the machine 1” above the curb and shut
the machine off if there will be a five (5) minute or longer wait until the next truck
arrives. If the wait on the next truck will be longer than 30 minutes pull the
Curbilder forward until the end of the curb form clears the extruded curb. Then
lightly spray the hopper and the inside of the curb form with either fuel oil or water,
depending on the curb mix used.
 At the end of a run, cut off curb with a shovel and finish with hand trowel as
required. The excess material may be reused if needed. Elevate the machine
approximately 4-5” using the three (3) crank adjustments (Two(2) in Front, One(1)
in Rear) and pull the Curbilder away from the fresh curb.
