RAISING AND

LOWERING SPINDLE

The spindle can be raised or lowered by loosening lock

knob (A) Fig. 45, and turning handwheel (B). To raise the

spindle height, turn the handwheel (B) clockwise. To lower

the spindle height, turn handle (B) counterclockwise.

The scale (C) Fig. 45, indicates the spindle travel range

from 0 to 3 and is marked in 1/16 increments. Minor cut-

ter height adjustments can be measured using the point-

er (D) along the scale (C). CAUTION: Always tighten lock

knob (A) after adjusting spindle height.

CHANGING SPEEDS AND

ADJUSTING BELT TENSION

The shaper is supplied with a 2-step motor pulley and

a 2-step spindle pulley that provides spindle speeds of

7,000 and 10,000 R.P.M. When the belt is on the largest

step of the motor pulley and the smallest step of the

spindle pulley, the spindle speed will be 10,000 R.P.M.

When the belt is on the smallest step of the motor pulley

and the largest step of the spindle pulley, the spindle

speed will be 7,000 R.P.M.

A chart (Y) Fig. 46, illustrating the correct belt placement

for 7,000 or 10,000 R.P.M. is located on the inside panel

of the motor access door.

To change speeds and adjust belt tension, proceed as

follows:

1. DISCONNECT THE MACHINE FROM THE POWER

SOURCE and open motor access door, as shown in Fig. 46.

2. Loosen thumb screw lock (A) Fig. 47. Release ten-

sion on belt by moving lever (B), to the left. Position belt

(C), on the desired steps of the spindle pulley (D), and

the motor pulley (E), and apply belt tension by moving

lever (B), to the right. When desired belt tension is

applied to belt, retighten thumb screw lock (A).

3. Proper belt tension is attained when there is approxi-

mately 3/32 deflection using light finger pressure (approx.

3.5 lbs.) at the center of the belt span between pulleys (D)

and (E) Fig. 47. IMPORTANT: Pulleys (D) and (E) should

always be aligned with each other to provide maximum

belt performance and reduce belt wear. To check pulley

alignment, refer to section “REPLACING SPINDLE CAR-

TRIDGE.”

REVERSING

SPINDLE ROTATION

MAKE CERTAIN THE MACHINE IS DISCONNECTED

FROM THE POWER SOURCE.

The motor is equipped with a reversing switch (X) Fig. 46,

which is located on the motor junction box. CAUTION:

Never attempt to reverse the rotation of the spindle with

the motor running.
