The scraper tool’s nominal swarf thickness and wear limit have been defined in
their test records as max processing limits for FRIALEN safety fittings and the
FRIAFIT sewage system. When processing fittings of other manufactures, note
the minimum pipe diameter for fusion.
An abrasion of the blade can enlarge the swarf thickness inadmissibly. This
abrasion occurs because of multiple usage and outside influences (sand, soil
etc.). Therefore the strength of the swarf must be measured regularly - e.g. with
a calliper gauge. Scraper blades are worn parts and have to be replaced (see
chapter 8).
NOTICE
An incomplete scraping or a differing swarf thickness may result in a leaking
fusion joint.

Replacement of blade
fig. 8
The scraper blade
(5) of your scraper
tool is made up of two blades. The
blade
(5) has been assembled by the
factory in such a way that the blade
with the number “1” is in use (see
fig. 8).
CAUTION
Risk of injury at the blade!
