TRIM SAWING
Trim saw cutting of rock material is best performed on material that is under 1/2" in thickness and less
than 4" in length. The rock slab to be cut should rest firmly and flatly on the saw table in front of the
blade prior to beginning a cut (fig 29). Cut the slab using light but firm pressure, letting the blade do
the work without forcing the slab. Forcing the material into the blade may result in a damaged blade
and possible injury to the user as well. Forcing may also stall the blade, overheat the motor, damage
the belt and yield poorly sawed surfaces of the rock material.

It is absolutely necessary that the user wear safety glasses while using the Cab Combo Workshop to
prevent eye injury. It is highly recommended to use a combination of personal protective gear at all
times such as face shield/safety glasses and a vinyl apron. Make sure the blade guard is in place and
adjusted as low as possible (to minimize the spray of cutting solution during sawing) but still clears the
top of the blade (fig 30). The height of the blade guard is adjusted with the guard thumbscrew (fig 31)
at the rear of the blade guard.
Should the blade be damaged for any reason, do not use the Cab Combo Workshop until the blade
is replaced. Continuous rim blades cannot be repaired if dished, kinked or damaged and should be
replaced with a new blade immediately.
CAB COMBO WORKSHOP OPERATION AND ADJuSTMENT
DIAMOND WHEELS
The Diamond Cab Combo Workshop comes equipped with two 6" OD x 1-1/2" wide brazed diamond
wheels in two diamond abrasive grit sizes (80 and 200 grit). Both wheels are manufactured to a low
tolerance OD circumference run-out for maximum wheel life and to prevent pounding and poor per-
formance during grinding. The high temperature brazed diamond bond provides excellent abrasive
performance when grinding the rough shape of the gemstone material. Diamond wheels must have an
uninterrupted flow of water during use for proper cooling and flushing.
A tool rest is attached to the reservoir base of the Cab Combo Workshop in front of both the 80 and
200 grit diamond wheels (fig 32). If a dop-stick is being used to hold the gemstone material, the user
can use the tool rest to securely hold the dop-stick while grinding, shaping and sanding. The tool rest
