Clean the four 8mm x 45mm cap screws with alcohol, install the flat washers, apply a dab of Loctite 
242 to the threads. Slide the front clamp onto the lead screw and reinstall the clamp to the frame 
leaving the mounting screws and clamping screws finger tight. 

 

Position the lead screw so that there is an equal length of it inserted into the front and rear clamps. 

Note:  The ends of the lead screw must be recessed from the exterior faces of the clamps. 

 

Move the beam towards the front of the table until it contacts the lead screw nut flange. Clean the 
three 4mm x 20mm screws with alcohol, install the flat washers, apply a dab of Loctite 222 to the 
threads and secure the nut to the tie-beam spindle using a 3mm Allen wrench, tightening them 
manually. 

 

Check the fit of the front bushing to the lead screw. Hold the bracket/bushing assembly 90 degrees 
rotated from the position it would normally be when attached to the beam. The assembly should just 
slowly rotate back down to the bottom. If it is too loose, you can turn the adjusting screw on the 
bushing to slightly tighten it. If it is too tight and won’t rotate down, you can turn the adjusting screw 
to slightly loosen it. If the bushing is too loose you can get a rumble or vibration, if it is too tight a 
squealing noise will result. Clean the two (6mm x 25mm) cap screws with alcohol, install the flat 
washers, apply a dab of Loctite 242 to the threads and install the front bushing & support to the tie 
beam leaving the screws finger tight. 

                  

 

 

Tighten the front clamp mounting screws to the frame with a 6mm Allen wrench using a crossing 
pattern, and apply 212 inch-lbs. of torque. Reinstall front limit switch by plugging into connector. 
Tighten the clamping screws (5mm) on the rear lead screw clamp to lock in the lead screw.
