MAINTENANCE
In general, just keeping your INCRA JIG clean is all you need to do to keep the tool in tip top shape. Occasionally, remove the
carriage from the base and brush or blow out any sawdust or debris that may have accumulated on the base and the UHMW
guide bearing strips. Use a toothbrush to clean the teeth on the INCRA racks on both the carriage clamp and on the carriage.
