Ridder RB50EPLUS - Attach the coupling piece to the tube motor

4.6 Aach the coupling piece to the tube motor
The condions and starng points that follow are applicable.
• Use pop-rivets to aach the coupling piece (16) (for a winding tube ø50 mm) to the tube (1.1).
Use a minimum of 4 pop-rivets (18) with a minimum diameter of 5 mm.
Do the procedure that follows.
1. Put the coupling piece (16) into the tube (1.1) of the tube motor (1). Make sure that the distance
into the tube is sucient to drill the holes (d) correctly in the coupling piece (16) and the tubes
(1.1/17). For the four recommended drilling posions (d) refer to illustraons 4.6.1/D-D. Drill
only in the permied part from the open end of the tube (1.1). Note: Drill the holes for the
winding tube (17) in §4.7.
2. Drill one of the holes for the pop-rivets (18) into the tube (1.1) and coupling piece (16)
(minimum of ø5.2 mm if pop-rivets of ø5 mm are used).
3. Use a pop-rivet pliers to aach the pop-rivet (18).
4. Drill the holes for the other three pop-rivets (18).
5. Use the pop-rivet pliers to aach the other three pop-rivets (18).
6. Put the winding tube (17) on the coupling piece (16) at a small distance from the tube motor.
This distance is temporarily necessary when the cord (20.1) is pulled through the winding tube
(17). Refer to step 2 of §4.7.
Do not drill into the tube motor more than 120 mm* from the open
end. *For the tube motor 550039 this is 194 mm.
Make sure that the connecons between the winding tube and the
tube motor are strong enough for the supplied drive torque.
Make sure that the connecons between the winding tube and the
tube motor are aached as smooth as possible.
This is important for the screen cloth.
