1Material and Tools Required
Lint-free cloths
Acetone as a solvent

2Maintenance Cycles
2.1 Linear guide
Relubrication must take place every three months, but after 600 km at the latest.
The lubricant is applied to the linear guide with a grease gun using the grease nipples provided.
2.2 Drive screw
The drive screw requires relubrication ca. every two months based on the grease that seeps
from the wipers. (Under normal operating conditions, it is sufficient to relubricate every 200 to
300 operating hours.)
The lubricant is applied to the drive screw using a clean paintbrush or brush.
Lubricant is applied to the nut with a grease gun using the grease nipples provided.
3Relubrication
Making the Components Accessible for Lubrication
1. Move the slider to the end position towards the motor.
2. Disconnect all electrical connections so that the axis is voltage-free.
Do not change the position of the axis during cleaning. For example, if the axis is set up
vertically, the slider can move due to its intrinsic weight and cause injury.

put the covers and the screws aside:
NOTE for variants with linear encoder:
Make sure that the tape measure (marked in the figure below) is not damaged!
Degreasing and Relubricating
1. Clean the guide rails and the drive screw using a lint-free cloth.
CAUTION: Risk of crushing!
2. Manually move the slider to the opposite end position.
3. Once again, clean the guide rails and the drive screw using a lint-free cloth.
CAUTION: Risk of crushing!
4. Repeat steps 1 - 3 (we recommend five times) to remove as much of the existing
lubricant as possible.
