Determination of wipe arc
Units in mm
Adjusting the park position
• Place the motor lever loose on the shaft, parking right or left(see drawing in
paragraph 3.4 and below for reference)
• Place the motor lever in such a way that it forms an almost straight line with
the connection lever(see drawing)
• Tighten the motor lever well now
• Place the wiper in the bulkhead
• Adjust the wiper arm to the correct length, if necessary.
Mount the wiper motor assembly and test run the wiper for a few minutes to
check if everything works well.
5.4 Rough determination of wiping arc and wiper blade
With this method the wiping arc and the
wiper blade length can roughly be
determined. Please contact your vendor
to calculate your configuration more
accurately.
•Determine length of pantograph arm
(L): L = E + D
•Get the maximum wiped area width
(W): W = ±0.9 * GW
•Find the intersection of L en W in the diagram below;
•The wipe arc-line closest to the intersection, shows the wipe arc;
•Find in the table below the vertical displacement of the blade (H);
•Now the wiper blade length can be calculated:
