6 Cleaning
Note
Festo recommends LOCTITE 7061 or an alternative suitable cleaning product for cleaning.
When using other cleaning products, ensure that they do not corrode the non-metal parts of the linear drive.
If in doubt, check the resistance of the non-metal parts with the help of the information on the Festo website
(
 www.festo.com ).
• Use a soft cloth and a gentle cleaning product to clean the spindle axis as and when necessary.
• Use a mild cleaning product to clean the cover band and the roller track as and when necessary.
7 Maintenance
7.1 Check the reversing backlash
Note
The reversing backlash (reversing clearance) must be checked with each maintenance. Increased reversing backlash
results in increased noise in the long term and ultimately to blocking of the lead screw or fracturing of the spindle nut.

• Check the reversing backlash of the slide module as described in the operating instructions (enclosed with the
spindle axis or available on the Festo website,

www.festo.com ).
7.2 Checking the cover band
• Check the cover band after every 2000 km operating distance.
Ripples on the cover band are a sign of belt reversal wear.
• If ripples form, retighten the cover band on both sides (  Chapter 4.4.6 on page 43 ).
If the cover band can no longer be retensioned:
• Replace the belt reversals (
