• Fix a hexagonal bit SW6 at the cordless screwdriver.
• Insert the hexagonal bit SW6 into the adapter at the knob (1).
• While scraping, press the cordless screwdriver axially against the
pipe end to be scraped.
• Ensure that the maximum permissible number of rotations per
minute of 200 rpm is not exceeded.
• Scrape until the pre-marked surface of the pipe end is com plete ly
scraped.
• The swarf is to be removed manually after the cordless screwdriver
was switched off.
6.
Disassembly of the scraper tool
• For disassembling of the scraping tool FWSG RA the blade holder
(3) has to be arrested.
• Press the blade holder (3) and rotate the detent (2), as previously
described.
• Remove the scraper tool FWSG RA from the pipe end.
7.
Inspection of the scraping result
Inspect the scraping result, i.e. the swarf must be completely removed
and the markings applied before with the FRIALEN marker may no
longer be visible.
For bundled coil pipes control the scraping result with regard to the
swarf thickness or remained marks on the pipe very carefully.
The blade is adjusted for a swarf strength of 0,15 – 0,25mm. For the
scraping of FRIALEN safety fittings the wear limit is max. 0,3mm and
must not be exceeded. Please note differing requirements of other
fitting manufacturers.
An abrasion of the blade can enlarge the swarf thickness inadmissibly.
This abrasion occurs because of multiple usage and outside in
flu -
ences (sand, soil etc.). Therefore the strength of the swarf must be
meas ured regularly - e.g. with a calliper gauge.
WARNING!
An incomplete scraping or a differing swarf thickness may result
in a leaking fusion joint.
