Range
1.
Make sure that the spindle rotation is turned
OFF
and the spindle is at a complete stop.

Use the charts below to find the spindle
speed range that includes the required
spindle speed for your operation.
Note:
The Model SB1025 spindle direction switch
on the control panel has four settings that
change the direction and speed of the spindle
motor for each spindle speed range. Positions
F1
(forward) and
R1
(reverse) use the low
motor speed, and
F2

as
a visual reference for the spindle direction
switch positions.
Properly setting the spindle speed range for
the Model SB1025/SB1026 involves correctly
positioning the high/low range lever AND
the spindle speed range selector. ALWAYS
make sure these two devices are properly
set before beginning the spindle rotation to
avoid damaging the machine and voiding the
warranty.
