6.2 Checking the cover strip
• Check the cover strip every 2000 km operating distance.
Ripples on the cover strip are a sign of belt reversal wear.
• If ripples form, retighten the cover strip on both sides (

Chapter 5.9 on page 41 ).
If the cover strip can no longer be retensioned:
• Replace the belt reversal and cover strip (
 www.festo.com/spareparts ).
6.3 Toothed belt pretension
Note
The toothed belt pretension is set to a specified value in the factory and is thus maintenance‑free for its entire lifetime.
The pretension of the toothed belt reduces due to storage time and operation. This is a normal process and not an
indication of wear.
Retensioning the toothed belt means increased wear and can lead to breaking of the toothed belt.
• Do not retension the toothed belt.
6.4 Relubricating the recirculating ball bearing guide
Note
Two lubricants are available for lubrication of the recirculating ball bearing guide of the roller bearing:
– Mineral-based lubricant (Festo LUB-KC1)
–
NSF‑H1 lubricant (“food grease” ELKALUB‑VP 922)
The two lubricants are not miscible and can decompose each other, in the worst case this can cancel out the lubrica-
tion and thus irreparably damage the axis.
• Relubricate with the same lubricant used to lubricate the roller carriages for delivery.
Lubrication notes and information (

ELCC-TB-KF operating instructions; www. festo.com ).
The recirculating ball bearing guide of the roller carriage must be relubricated at specific intervals (  Note on lubrication
interval).

All other lubricated parts of the cantilever axis are equipped with lifetime lubrication.
The recirculating ball bearing guide of the roller carriage should be relubricated after a load-dependent lubrication
interval S
int
. To determine the lubrication interval, the load comparison factor f
v
must be calculated using the formula for
combined loads operating instructions (
