Make sure you are using the right screwdriving bit.
l
Make sure you are using the vacuum sleeve that corresponds to the screwdriving bit. You can use a different sleeve if it appears
to be more suitable for your application.
l
Make sure the adjustment of the vacuum coupler allowsfor the appropriate holding of the screw against the vacuum sleeve.
Please refer to the Vacuum Coupler Adjustment section and optimize the adjustment of the vacuum coupler accordingly.
l
Make sure the picking position defined is aligned and at a perfect 90-degree angle perpendicular to the Screwdriver and screw-
driving bit. Please refer to the Picking Screw section to orient the device using the ActiveDrive feature.
