Nut & Cap Screws

6.

  Re-install the key onto the leadscrew so that 

you can use the ball handle in the next step.

7.

  Use the T-handle hex wrench or similar 

tool to rotate the adjustment plate on the 

leadscrew nut in small increments, then 

rotate the cross slide ball handle to check the 

amount of backlash.

8.

  When you are satisfied with the adjustment, 

re-tighten the two cap screws.

9.

  Re-install the parts previously removed in 

the reverse order.

Power is transferred from the motor to the 

spindle with heavy-duty ribbed belts. With 

normal use, these belts will gradually stretch 

over time. When they do, perform the follow 

procedure to re-tension them.

Tools Needed

Hex Wrench 10mm ...............................................1

To re-tension the belts:

1.

  DISCONNECT MILL FROM POWER!

2.

  Loosen the two motor mount cap screws, one 

on each side of the motor (see Figure 65).

3.

  Push the belt tension adjustment lever 

back with moderate force, then tighten the 

adjustment cap screw in and against the 

motor mounting plate to secure the setting.

4.

  Re-tighten the motor mount cap screws.
