Adjusting Backlash; V-Belt Replacement - Grizzly G0695 Owner's Manual

Adjusting backlash

Leadscrew backlash is the amount of motion the
leadscrew rotates before the device begins to
move. Leadscrews always have a certain amount
of backlash that will increase with wear. generally,
0.005"–0.010" of backlash is acceptable.
the backlash of the longitudinal and cross
leadscrew can be adjusted by changing the gap
in the leadscrew nuts (see figures 63–64).

Use a 5mm hex wrench to tighten or loosen the cap
screws on the leadscrew nuts shown in figures
63–64, then test the amount of backlash by slowly
rocking the handwheels back-and-forth.
