WARNING!
If the oxide layer is not removed completely, inhomogeneous, leaking
fusion joints may result.

WARNING!
The FWSG 710 scraper tool must in all circumstances be used for fittings
from d 710.

A one-time, complete removal is sufficient (min. 0.15 mm).

Damages to the pipe surface as e.g. axial grooves or scratches may not be
located within the fusion zone.

WARNING!
An excessive swarf removal may result in an excessively large annular
gap which either cannot or only insufficiently closed by fusion (for the
remedy see item 4.8).

Please thus regularly check the condition of the blade at the manual
scraper and the wear of the scraper blade at the scraper tool. Worn blades
must be replaced (see FRIALEN

®

 Info No. 1).

Please note that the indicated wearing margin applies to FRIALEN

®

Safety Fittings. Where appropriate please observe manufacturers’
indications.

Filing or sanding are not permitted because contaminations are
introduced.

For a control of the complete surface removal over the entire surface, we
recommend to apply marking (control) lines (see Figure 3). If during scraping of
the surface non-scraped areas occur at some points (e.g. in case of oval pipes),
these areas are to be reworked.
