Inspection Procedure and Maintenance
Inspection Procedure
1. During routine maintenance or in the event of a customer concern for wiper performance, please
inspect wipers for any performance concerns.
HINT
• Bugs, sap, road grime, car wax treatments, and other contaminants on the rubber inserts
or windshield, can cause wiper performance concerns.
• Make sure to complete the Inspection Procedure and the Cleaning Procedure before
deciding to replace the rubber wiper inserts or other wiper related parts.

Inspection Procedure (Continued)
2. Contributors to poor performance/decreased rubber wiper insert life (requiri ng rubber wiper
insert replacement).
• Dust or dirt on the glass surface causes the rubber edge to wear quickly.
• Sand and salt used for road conditioning during Winter months causes the edge to wear
quickly, so geographical locations with significant snowfall require more frequent rubber
wiper insert replacement.
• Heat and length of time in service can cause the rubber to become hard and brittle causing
the rubber to not turn over, resulting in streaking and/or unwiped areas on the glass.
• The use of an ice scraper near the blades can easily damage the rubber insert.
• Pulling blades off a frozen windshield can cause the rubber insert to tear.
• Using wipers instead of an ice scraper to remove frost and ice from the glass can dull ,
nick, or tear the rubber.
•
Slamming the wiper on the glass to remove ice & snow can cause the blade to bend and the
rubber to come out of the blade increasing the potential to scratch the glass.
• When ice forms in wiper blade pin joints, it may cause streaking and unwiped areas. To
remove ice from pin joints, compress the blade and rubber with your hand to loosen the
frozen joints.
Cleaning Procedure
1. If any performance concerns a re found , clean the rubber wiper inserts and the glass surface
using the following cleaning procedure.
A. Rubber wiper inserts: Clean road and
Figure 2. Rubber Wip er Insert
environmental debris from the rubber inserts
by using a cloth or paper towel soaked with
windshield washer fluid or a mixture of mild
detergent and water.
NOTICE
Do NOT use fuel, kerosene, or petroleum
