FIGURE 13—DC motor and speed control assembly.
Press the two nuts into the hex shaped depressions in the
rear of the inner belt guard and secure the outer cover with
two 1-3/8" pan head screws through the covers and into
the nuts. Don’t fully tighten until everything is aligned.
FIGURE 11—Attach outer belt guard.
4. On top of one end of the two belt guard halves you will
see two “ears” with holes in them. These are where the
speed control housing pivots. On the plate on the bottom
of the speed control housing are two pins that go into
these holes. Put the pin closest to the motor in place, then
bend the other “ear” away from the motor far enough that
you can engage the other pin so the cover pivots on these

in belt guard tabs.
pins. The plastic is exible enough so that you can do this
easily and it will spring back into position.
5. Attach the motor mounting bracket to the rear of the
headstock with two 10-32 x 7/16" socket head screws.
These screws are shipped threaded into the headstock
rather than in the parts bag. There is enough “play” in the
mounting holes to allow the motor to be adjusted so it is
parallel with the spindle axis. (NOTE: If a chip guard is
to be mounted, its attachment screw replaces one of these
mounting screws. It can be mounted at this time or after
the headstock is in place. See instructions that come with
the chip guard.)
6. Place the drive belt over the spindle pulley and insert the
two 10-32 x 3/4" socket head screws (with 2 washers
on each) through the motor mount slot and into holes
in the ends of the motor standos which are exposed
through locating holes in the outer belt guard. The
normal operating position for the drive belt is on the
large diameter groove on the motor pulley and the small
diameter groove on the spindle pulley. Use of the other
(high torque) position is discussed elsewhere in the
instruction manual.
