Preparation of scraping
WARNING!
Bundled coil pipes must be
re-straightened within the working
area of the scraping tool be fore scraping.
• Remove all dirt such as sand and soil from the pipe surface (e.g.
using a clean, greaseless cloth).
IMPORTANT!
If the pipe surface to be scraped has not been cleaned the blade
will wear out early.
• If a fitting has to be fused, mark the insertion depth on the pipe end
with a FRIALEN marker pen.
• Mark the area to be scraped with a FRIALEN marker pen using wavy
lines. In case of bundled coil pipes particularly the inside curve has
to be marked (this is for you to determine whether pipe has been
scraped completely)
