Maintenance Schedule

Perform the following maintenance tasks after delivery or long storage.

Interval¹⁾	Action
After delivery, every 1000 km (621 miles) or within the first two months of service life	Verify the Heavy-Duty carriers by visual inspection for any damage or missing parts, especially for moving parts and parts at risk for collisions such as mounting elements
After ≥ two years of storage	Verify the lubrication pads of the Heavy-Duty carriers and replace them if necessary. Refer to Replacing Parts.

Perform the following maintenance tasks within the stated intervals.

NOTE: The intervals in the following table are guidelines. The intervals can be adjusted depending on your application and the environmental conditions (track length, number of Heavy-Duty carriers, motion profile, temperature, etc.).

Interval²⁾	Action
Every 1000 km (621 miles) of operation	Clean the Lexium™ MC12 Heavy-Duty guide system if necessary. Refer to Cleaning. Verify that the floating bearing of the lower rollers of the Heavy-Duty carrier moves freely in axial direction. Clean if necessary and make the rollers run smoothly. Refer to Cleaning the Carrier Rollers. Verify the lubrication pads of the Heavy-Duty carriers for dirt and clean if necessary. Verify the lubrication pads of the Heavy-Duty carriers for wear and replace them if necessary. Refer to Replacing Parts. Lubricate the Heavy-Duty carriers. Refer to Lubricating the Lexium™ MC12 Heavy-Duty Carrier.
Every 4000 km (2485 miles) of operation	Clean the Lexium™ MC12 Heavy-Duty guide system if necessary. Refer to Cleaning. Verify the covers of the segments and the drive magnets of the Heavy-Duty carriers for dirt and magnetic abrasion. Clean the covers and the magnets and remove the magnetic abrasion if necessary. Refer to Removing Particles from the Magnets. Verify the Heavy-Duty carrier rollers for dirt and clean if necessary. Verify the lubrication pads of the Heavy-Duty carriers for dirt, and clean if necessary. Verify the area of encoder magnets of the Heavy-Duty carriers for dirt, and clean if necessary. Verify the rails for dirt and clean if necessary. Remove the Lexium™ MC12 Heavy-Duty carriers from the guide rail, refer to Removing the Lexium™ MC12 Heavy-Duty Carrier from the Lexium™ MC12 Heavy-Duty Guide Rail. Verify it by visual inspection for any damage or missing parts, especially moving parts and parts at risk for collisions such as mounting elements. Verify the drive magnets of the Heavy-Duty carriers for damage. The drive magnets cannot be replaced individually. Replace the plate with the two magnets as a whole if necessary. Refer to Replacing the Drive Magnets of the Carrier. Verify the encoder magnets of the Heavy-Duty carriers for correct seating and for damage. Adjust or replace if necessary. Refer to Replacing the Encoder Magnet of a Carrier. Verify the rails for wear or damage and replace if necessary. Reinstall the Heavy-Duty carriers and the guide rails and mount them according to the descriptions in Mechanical Installation. Verify all parts for bolted connections.
Every 10.000 km (6214 miles) of operation	Verify the Heavy-Duty carrier rollers for wear and replace the Heavy-Duty carrier rollers if necessary. Refer to Replacing Parts.

Perform the following maintenance tasks if your Heavy-Duty carriers have exceptional movement profiles:

Movement profile	Action
Reversing movements in which the Heavy-Duty carriers travel a distance of less than 200 mm (7.88 in).	If a distance of less than 200 mm (7.88 in) is travelled, perform a lubrication run after 20.000 traverse cycles or earlier.

¹ The distances referred to are for one Heavy-Duty carrier. The performance of your system may differ.
