the screw contact pattern.

Maintenance
With trapezoidal screws, regularly lubricate the screw.
With ball screws (R-Version), observe the following guideline: lubricate approx. every 200 hours with
1ml per 10mm of screw diameter. For N-Version: Ball screw with lifetime lubrication
Approx. 5 operating hours after commissioning: Retighten all attachment bolts.
After approx. 200 operating hours or 1 year (sooner in tough operating conditions): Check the screw
nut for signs of wear and tear.
Clean the screw of old grease and relubricate.
After approx. 5 years: Disassemble gear, clean it of old grease and relubricate:
1.
Remove the two grub screws at the bearing cover
2.
Take the screw out (remove screw protection if required).
3.
Unscrew the bearing cover.
4.
Remove the old grease.
5.
Refill with new grease.
6.
Strongly press the bearing cover down (10 times the normal contact force).
7.
Loosen the bearing cover again.
8.
Put the bearing cover into place and fasten it with two grub screws.
Attention!
When assembling the bearing cover, make sure it fits smoothly and that there is no axial play.
Attention!
Change the screw nut if the axial play exceeds 1/4 of the thread pitch (trapezoidal thread).
