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.

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

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 standos 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.
