Withdrawal
Raise the wiper arm slightly and hold it in this position.
Slide the slider and remove the wiper blade from the arm. On the closed side of the rubber, squeeze the two steel strips with pliers: remove to the side from the top bracket and pull the rubber along with the strips from the steel brackets of the wiper blade.
Installation
Pre-insert a new elastic band without fixing strips into the lower brackets of the brush.
Insert both slats into the first groove of the elastic so that the notches of the slats point towards the elastic and fit into the rubber protrusions of the groove.
Squeeze two steel strips and an elastic band with pliers and insert it into the upper bracket so that the protrusions of the bracket on both sides fit into the grooves for attaching the elastic (arrows).
Put the brush on the wiper arm and slide back the fastening bar.
Tilt the wiper arm back towards the glass. Make sure that the rubber band adheres to the glass along its entire length.
