Replacement

1

Jog axis to extend way cover and press [E-STOP].

2

Remove these parts from the machine:

  • Telescopic way cover [1]

Caution: The way cover has sharp edges. Use the leather gloves when you handle the way cover.

Turn the way cover upside down.

Remove each section of the way cover by expanding the smallest leaf.

Apply outward pressure and rock the leaf back and forth to separate all the leaves.

3

Wipe off excess grease [1] and inspect the brass seals [2], plastic slides [3], and bumpers [3]. Use the mallet to remove any dents from the way covers.

Note: Bumpers were added starting September 2021. However, they are not backwards compatible. If a bumper is damaged or missing, the way covers will still function properly. 

4

Select the wipers according to size for each leaf. There should be no cutting needed.

Inspect clear tubing before new wiper installation and make sure the length of the clear tubing is fully inserted in the proper channel of the wiper. 

Install the REPLACEMENT WIPERS [A]. Put grease on the REPLACEMENT WIPERS [A]. Use the mallet to tap the REPLACEMENT WIPERS [A] into the slots.

Install each leaf one at a time by placing one edge of the leaf inside the front edge of the larger leaf, apply downward pressure to insert the other side. 

Note: Use the flathead screwdriver [B] to help pry the way cover leaf to insert another leaf.

Evenly apply force over the entire cover to help compress the clear tube and slide the leaf into place.

Follow this process to install all the leaves.

5

Remove chips and debris from the linear guides.

Clean the table mounting surface.

Apply a thin coat of grease to the way cover guide bars [1].

Install the way cover over the guide bars.

Attach the way cover end panel to the way cover guide bars. Use the (2) fasteners [2].

Move the table [4] to the full X-Axis travel.

Fully extend the sections of the way cover [3]. Make sure the way cover moves correctly and is the correct length.

Lightly spray a multi-purpose lubricant onto the tops and sides of each of the way cover panels.

6

Move the largest section of the way cover away from the table.

Put the RTV ASI 335 sealant on the way cover where it touches the table mounting surface [1].

Put a small amount of RTV ASI 335 sealant on the horizontal seam [2] between the way cover and the table.

Attach the way cover to the table with the (8) fasteners [3].

Remove any sealant that is squeezed out of the space between the way cover and the table.

Release the [E-STOP] and press [RESET] a couple times to clear the alarm.

Check the X-Axis and Y-Axis movement to make sure the way cover does not bind.
