Adjust the height of the cutter drum with the
Hand Wheel and T-Handle. (Turn the hand
wheel to raise the cutter drum off of the
substrate. Lower or raise the T-Handle to
engage or disengage the drum after setting
the proper cutter depth.)
Set the depth of cut to allow the cutters to go
through only the materials to be removed.
Make certain that the drum is positioned to
where only the cutters strike the surface,
and that the drum assembly never comes
into contact with the substrate.
the cutter
tips alone should strike the surface
(1/8”
to 1/4” maximum depth per removal pass on
new cutters).
The drum will not withstand substrate
contact.
contacting the removal surface
too deeply will cause premature wear
to cutters, shafts, drum and other
components!
Too much downward pressure only has
negative results. Try to remove materials
in several passes rather than one, deep
pass. Several tests will show the best, most
appropriate cutter impact. Use a forward,
backward and/or circular pattern to achieve
your desired finish.
note:
Only use a forward motion when the
CM2150 or CM2550 carbide milling cutters
are used.
tIP:
Positioning the machine over the
surface in many directions, as well as dialing
the hand wheel up or down can help create
desirable surface patterns.
After several hours of practice, the operator
will become comfortable and should be able
to remove materials faster with enhanced
results.
When the job is completed, or the operator
wants to cease work, stop the engine by first
lifting the drum above the substrate using the
hand-wheel and/or the T-Handle. Stop the
machine only at the engine. Then close the
Propane Supply Valve on the tank to shut off
the fuel supply.
The drum assembly must be removed daily
and inspected for drum wear, hole elongation
and possible weld separation. Replace the
cutter shafts every 40 hours, or prior to any
drum wear. If the drum’s center holes are
elongated, order another SMITH cutter drum.
