IMPORTANT!
Do not change the wiper blade in the field without using Activator 7649.
The cure time for Loctite 242 without Activator 7649 is 24 hours. Replacing the wiper
blade without using Loctite or allowing sufficient cure time can result in the wiper
blade loosening and losing contact with the optic face, or even detaching in .

Remove the wiper assembly consisting of the wiper arm and wiper blade by undoing the
wiper arm thumbscrew with your fingers or pliers. To reduce unnecessary stress on the
wiper drive system hold the wiper arm while turning the thumbscrew counter clockwise.

2.
The wiper armature incorporates a slot with a circular opening at the distal end that allows
the wiper material to be maneuvered out of, or into the slot. Slide the old blade off the wiper
arm by sliding it towards the distal end and pulling it through the slot. Pliers may be needed
to achieve this. Feed the new wiper blade onto the wiper arm through the distal slot.
