Step 7 – Centering
•
Check that the roller package is centred between the frames’ wall attachments. See ”Figure 4.9”. If necessary,
adjust the roller laterally by carefully bending between the bearing plate and roller.
•
Install the bearing’s excenter-locking ring on the “non-motor side” and turn clockwise. Lock the locking ring by
knocking it with hard blows for ½ - ¾ turn. Use a drift that is inserted in a pre-drilled hole. Tighten the locking
screw. See ”Figure 4.10a-d”.
•
Tighten all the screws in the bearing.
