Adjustments

Timing Belt

The timing belt should have 1/2" to 3/4" give with
six pounds of pressure applied. The timing belt
has been properly tensioned at the factory and
should not be adjusted when you receive the
machine.
As the machine receives use, however, the
timing belt may eventually need tightening. To
tension the timing belt:
1. Move the table to the left.
2. Loosen one of the hex nuts (A, B, Figure 13)
and turn the socket screw (C, Figure 13)
with a hex wrench as needed.
3. After getting the desired tension, tighten the
hex nuts (A, B, Figure 13) against the plate.

Operating Controls

(Figure 14)
The emergency stop button remains engaged
after being pushed; to re-start the machine,
rotate the stop button until it pops back out.
NOTE: The machine will not start if the electrical
cabinet is open.

Operation

Longitudinal Movement of Table

1. Loosen the socket head cap screws in the
limit blocks (A, Figure 15), and slide the limit
blocks to the desired position. Retighten the
socket head cap screws.
2. Move the table using the handwheel (B,
Figure 15) and lock the table in position by
tightening the knurled knob (C, Figure 15).

Crossfeed Movement of Table

The crossfeed handwheel (D, Figure 15) has a
scale for precision setting. The crossfeed
movement of the table can be locked by
