Figure 23

The shaper is supplied with a two-step spindle pulley that

provides spindle speeds of 8,000 and 10,000 RPM. With

the belt on the upper pulley (A), the spindle speed will be

10,000 RPM. With the belt on the lower pulley (B), the

spindle speed will be 8,000 RPM.

To change speeds, loosen indexable locking lever (C), and

release tension on belt. Position belt on desired spindle

pulley, reapply tension to belt, and tighten locking lever (C).

To check for correct belt tension, use light finger pressure

on the belt between the spindle pulley and the motor drum.

A deflection of no more than 3/32” should be noted.

Figure 22

To apply power to the machine, turn knob (A) to the right

for forward operation, and to the left for reverse operation.

Never attempt to reverse the rotation of the spindle while

the motor is still running.

The spindle can be raised or lowered by

unlocking spindle locking lever (C) and turning the

handwheel (B). To raise the spindle height, turn handwheel

clockwise. To lower the spindle height, turn handwheel

counter clockwise.

Once you have determined the proper spindle height, it is

important to lock the spindle. Rotate the indexable locking

lever (C) toward lock until it is tight.
