The bearing must be able to move. It must
therefore be regularly greased with a grease
gun, at least every 50 operating hours.

Movement of the frame
Delay in switching off the sensor is regulated by a tension
spring (1).
• Increased tension on spring (1) = longer delay in
switching off = more force on metering rollers
• Reduced tension on spring (1) = shorter delay in
switching off = less force on metering rollers
