2.1.3. drive/tube assembly
1) Slide the drive into the roller tube.
For roller tubes which are smooth inside, position the notch

previously cut on the boss on the crown.
2) The drive wheel must be locked in place to prevent it

moving along the roller tube:

• This can be done either by fixing the roller tube to the

drive wheel using 4 x Ø 5 mm self-tapping screws,

or by using 4 x Ø 4.8 mm steel pop rivets placed 5

mm to 15 mm from the outer rim of the drive wheel,

regardless of the roller tube.

The screws or pop rivets must only be attached to the

drive wheel and not to the drive.

3) Slide the end cap into the roller tube.

2.1.4. Installing the drive/tube assembly

The motorised product must not be compressed between the brackets

1) Install and fix the drive/tube assembly onto the end

bracket

f and onto the drive bracket g:

Ensure that the drive/tube assembly is secured onto

the end bracket. This operation prevents the drive/

tube assembly from coming out of the end bracket

mounting when the roller blind reaches the lower end

limit position.

2) Depending on the type of bracket, fit the stop ring

h in

place.
