Cutting Operation - Delta 20-142C Instruction Manual

Cutting Operation

Figure 14
Clamp the workpiece securely in the vise. Turn
on the saw and allow the motor to come up to
full speed before touching the workpiece with
the wheel.
Figure 15
Lower the wheel (A) lightly until it makes contact
with the workpiece. Continue to firmly push
down on the handle while the cut is being made.
NOTE: Do not allow the wheel to chatter and
jump as this can cause the wheel to wear out of
round, resulting in poor quality of cut and, possi-
bly, broken wheels.
Figure 16
Do not slow up when coming through the
bottom of the cut. This keeps the metal from
overheating and dragging off in a heavy burr.
Figure 17
This view shows a finished cut-off operation.
NOTE: The number of cuts per wheel, as well as
the quality of cut, will vary with the speed and/or
type of material. Fast cuts cause the wheel to
wear more rapidly, but also help to reduce
discoloration and burr.
