Check that the clearance between screws in the rail groove and the

large, a screw pile or screw jump will occur.
・
If any adjustment is required, loosen the holding plate attaching screw
and move the plate up or down.

. Checking and adjusting the front/rear positon of the
rail
If the rail comes into contact with the escaper, or the clearance be-
tween the rail and escaper is too large, when the machine is operated,
loosen the rail fixing bolt and adjust the rail either backward or forward.
After making an adjustment, be sure to tighten the rail fixing bolt.
・
If the rail hits against the escaper, the escaper will not function properly.
・
If the clearance between the rail and the escaper is too large, screws
may fall into the machine.
After making an adjustment, try making a vibration readjustment by
referring to “Checking and Adjusting the Rail Vibration”.
