Way covers keep chips and coolant away from the ballscrew, guiderails, and home switch. Machines can have three types of way covers.
|Symptom||Possible Cause||Corrective Action|
|The wipers are worn or damaged.||Normal wear on wipers.||Replace the wipers.|
|Incorrect coolant being used.||Refer to the Improper Coolants section in the manual.|
|The way covers are damaged or worn.||A part or other heavy object dropped on the way cover.||Remove the dents from the way cover.|
|Cutting abrasive or absorbent materials.||Extra protection is necessary when you cut abrasive or absorbent materials.|
|The way covers are not lubricated correctly.|
|Chip build-up around the base of roll shade way covers.||Clear debris from the base of the covers and adjust the tension on the spring-loaded canisters.|
|Way covers "pop," or do not move evenly.||Normal operation.||These symptoms are normal during operation and do not require troubleshooting.|
|Way cover has trouble extendening or retracting.||Way cover is full of chips.||Perform normal machine maintenance.|
|The way covers are rusty or make excessive noise.||There is a low coolant concentration.||Increase the coolant concentration.|
|Way cover movement during dry machine operation creates friction.||Lube the way covers with oil.|
|The rail screws are loose.||Tighten the loose rail screws.|
Symptom: Way covers "pop," or do not move evenly.
Possible Cause: Normal operation.
Tight way covers can sometimes make a "popping" noise when they move. This is normal, and does not require troubleshooting.
If there is an excessive amount of noise from friction, go to Section 4 to troubleshoot the "excessive noise" symptom.
