5. Maintenance
5.1 General maintenance
To keep the Exalto wiper in good condition, you are advised to:
• clean wiper arms and blades with fresh water after every journey in salt water (to prevent
salt from clogging moving parts);
• never use the wiper on a dry window.
5.2 Servicing
As long as the wiper system functions normally and is kept in good shape (see paragraph
5.1), servicing the motor is not necessary. Check yearly (monthly when used intensively)
if the wiper blades are worn. Replace blades when worn or when the blades leave many
stripes across the glass. In case of failure or adjustments, have servicing done solely by
qualified mechanics. In chapter 6, Troubleshooting, a list is given of possible problems and
their solutions.
5.3 Changing the wiping arc and park position
If the wiped area is not optimal, the wipe arc and park position can be changed. Always
disconnect the electric before opening the housing.
5.3.1 Adjusting the wipe arc
1.
Remove the wiper arms from the shafts;
2. Move the screw in the slot from the shaft lever away from the shaft for a smaller and
towards the shaft for a larger wipe arc;
3. Fasten the nut again (33Nm/25 ft.lbs);
4. Place the motor lever in the desired park position (see paragraph 5.3.2).
