Adjusting the Guide Wheels
The guide wheels are pre-adjusted for a standard 15lb. rail width from the factory. The following
procedure should be used to ensure proper placement on the guide rail.
If the guide wheels are not adjusted to the appropriate guide rail width, loosen (don’t remove) the
precision rail mounting bolts (x4) on the sensor assembly.
The bolts allow you to adjust the wheel mounts to fit the guide rail. Slide the sensor assembly back
onto the base and slide the whole assembly onto the rail.
Set the wheel rail width so that the wheels are not too tight against the rail. Tighten the 2 outside
precision rail bolts. Now move the assembly away from the guide rail and tighten the inside bolts.
Now move the rail back onto the guide rail and secure the assembly mount to the crosshead.
