Caution: There is a magnetic strip on the measuring linear guide. Do not use anything other than a clean soft towel to clean the linear guide. Scrapers, screwdrivers etc. will permanently damage the rail. Keep magnets, (indicators magnetic bases for example) away from the linear guide and scale components when working inside the machine.
Disable the linear scale in the control. Enter 0 (zero) for the grid offset value.
Unbolt the way covers and slide them back.
Disconnect the linear scale cable from the read-head cable. Remove the cable clips and ties that secure the linear scale cable.
Important: Take note of the cable routing and the how the cables are fastened.
Note: The linear scale housing is permanently attatched to the truck (See illustration in the Installation section). DO NOT remove the housing from the linear guide truck.
Remove the 4 bolts holding the linear guide truck to the casting.
Note the orientation of the truck.
Remove the truck/guide assembly by sliding it off the end of the guide; the bearings are held captive in the truck.
The truck should be slid off the guide probe-end first, if this is not possible be very careful as the body of the truck leaves the rail. Twisting or bending motion can damage the read head.
Position it so that the bolt holes in the casting and the linear guide truck are in line.
Install the four bolts.
Route the linear scale cable, securing it to the lube line, as necessary, with cable ties.Refer to the notes taken from the “Removal” section to correctly route the cables.
In addition, use the following illustration for an example of cable routing. Do not stress the cable, avoid sharp edges when routing and observe the proper bend radii of the cables.
Important: Damage to the cables is the most common cause of faults.
Connect the scale cable to the cable from the read-head cable. Hand tightening is all that is necessary, do not use tools on the union nut.
Enable the scale in the control, set grid offset and verify full travel
