SERVICE ADJUSTMENTS
3. Check the alignment with a straightedge. If the pulleys are in
alignment, the straightedge should touch two sides of each
pulley evenly. Figure 25.
4. If pulleys are parallel with each other, but not in line, remove
the belt from the spindle assembly and slide the spindle
cartridge assembly either up or down.

V-BELT TENSION

You should be able to deflect the belt 1⁄4" with moderate finger
pressure. This may seem tight compared to most other V-Belts,
but since the belt is small and runs fast, this much tension is
necessary. The V-Belt will slip if too loose and squeal or cause
vibration if too tight. Adjust the tension if necessary.
To adjust V-Belt tension:
1. DISCONNECT SHAPER FROM POWER SOURCE!
2. Make sure the pulleys are properly aligned.
3. Loosen the two motor mount plate bolts and slide the motor
left or right to modify the belt tension. Keep the pulleys aligned.
4. Tighten the motor mount plate bolts, test the tension, and
check pulleys.
5. Repeat Steps 3-4 until tension is correct, and pulleys are
aligned.

gIB ADJUSTMENTS

The spindle gibs ensure there is no play in the spindle that could
cause it to wobble.
To adjust the spindle gibs:
1. DISCONNECT SHAPER FROM POWER SOURCE!
2. Elevate the spindle to its maximum 3" height.
3. Test the spindle for movement from left to right after
tightening the spindle assembly lock knob.
4. If there is movement, adjust the gib against the elevation
housing, using the adjustment screws at the top and bottom
of the elevation housing. Figure 26 shows the two upper gib
adjustment screws and locknuts. One of the two lower
adjustment screws is also visible in the photo.
Fig 25. Inspecting pulley alignment.
Note: The side cover can be removed from the shaper to improve
access to the motor.
5. Inspect for tilt on the motor pulley. If the pulley is tilted, loosen
the four bolts holding the motor onto the motor plate. Wiggle
the motor into position. (Do not loosen the bolts that hold the
motor onto the motor mount; this plate is preset with blocks
that hold it in position and it cannot be adjusted.)
6. Inspect your results. If they are satisfactory, tighten all
fasteners. Remember to tighten the bolt in the split housing
that holds the spindle cartridge in position.
N O T I C E
DO NOT over-tighten. Cast iron threads
are more easily stripped than steel.
7. You can also align the motor pulley by raising or lowering it
along the motor shaft. Loosen the two setscrews and tap into
the desired position with a dead blow hammer.

TRUINg ThE FENCE

To ensure that the fence is parallel with itself and square
with the table:
1. Ensure that the bolts through the wood facing on each side are
tight and adequately countersunk.
2. To align the wood facing, adjust one or both fence halves so
they are in close alignment. Micro-adjust and check the
alignment with a straightedge.
3. If the wood fences are not coplanar with each other,resurface
as one unit. You can perform this operation on a jointer.
Note: Make sure the screws are countersunk deep enough so
the workpiece will not come in contact with the heads
of the screws.
Or use electrical washers between the fence and the fence
bracket to shim the fence into the correct position.
