While setting up the Hydro-Wiper, the brush arm can be manually
moved to check the OBS3+ is correctly positioned. Ensure that the
Hydro-Wiper is not powered up prior to doing this.
The brush is mounted on an adjustable arm. The length of the arm
controls the brush pressure applied to the face of the OBS3+. This
has been factory set, and should not need adjustment.
If it is necessary to adjust the brush pressure, this can be done by
loosening the lock nut at the end of the wiper arm and rotating the
wiper arm in the desired direction. The lock nut should be tightened
after adjustment.
If there is excessive brush pressure, the life of the brush will be
reduced and damage to the optical surface of the OBS3+ may occur.
If the brush pressure is insufficient, contact between the brush and
optical window will be lost in the centre of the window and fouling
may occur.
The cable between the wiper housing and wiper control module
should be fully secured in position. If it is free to constantly move in
the water currents, damage from fatigue and eventual failure may
result.
