Footblock Cleaning and Lubrication: All Current CMC Models

A Twisted Corner is when the Blade rotates before fully retracting from the matboard, which tears the matboard and twists the corner.

• This is especially visible from the back of the mat.

The Footblock may become clogged with matboard debris over time, keeping it from plunging/retracting properly.

• This can cause tearing in the corners and problems with circles.

• When paper dust and other materials build up inside the Footblock it won’t slide consistently.

This procedure will walk through lubricating the Footblock allowing it to move smoothly.

Compressed Air Gun.

Dry Silicone Lubricant. We recommend dry silicone lubricant for our equipment because it lubricates even when dry and does not drip onto the mats. Below are suggestions but not the required brands; there are many other types available in your local hardware store.

• CRC0324 CRC “Chute Lube”

• 91110 Super Lube Silicone, Aerosol

Turn the ECU/Driver Pack off.

Move the Head to the right side of the Board where there is easy access to the Footblock.

Remove the Blade Cartridge.

Using the compressed air, spray liberally into all openings on the Footblock including the side and top to remove any debris.

Make sure to get all openings.

Spray 100% Silicone Lubricant Spray (not GEL) in all openings and moving parts on the Footblock assembly.

• Do not use oil, grease, WD-40, etc.

Insert the Blade Cartridge and push the Blade Cartridge in and out to work the lubricant into the parts.

You may need to repeat this step.

Clean all exposed parts with a clean cloth.

When you are finished, move the Head back to the Home position and turn on the ECU/Driver Pack.
