Removing
1. Turn on the wipers, then stop them in the park position.
2. Throw off a protective cap from a nut of fastening of the lever, then give a nut.
3. Take the brush away from the glass and remove the lever from the spindle. If necessary, gently pry off the stubborn lever with a large flat-blade screwdriver.
Installation
Before landing the lever carefully clean its spindle. Make sure the position of the brush is correct, then screw on the fixing nut and tighten it to the required force. Install the protective cap on the nut.
