The FWSG 710 L scraper is for use
on PE pipes with a diameter ranging from 10" IPS – 28" IPS and
10" DIP – 20" DIP. It is designed to
remove completely and effortlessly
the layer of oxide in preparation for
an electrofusion joint.
The design of the FWSG 710 L
(Picture 1) allows scraping of the
pipe surface along the entire length
of the coupler or half of it:
• Scraping the entire length of the
coupler is required when a slideover coupler is employed.
• Only half the coupler (up to where
insertion will end) needs to be
scraped when a simple fusion
process is to be applied.

The appropriate dimension ranges
are marked twice along the
scraper's guide rod. The first
marking nearer the front plate
serves to set the areas to be
scraped for a simple fusion
process. The second marking
nearer the end plate refers to the
employment of slide-over couplers.

I. Preparation
• Remove obvious dirt particles
from the pipe surface to be
scraped (using for example a
clean, grease free piece of cloth).
• Determine length of area to be
scraped (= depth of insertion of
coupler/moulded part + 0.2")
and mark area with wavy lines
using a FRIALEN®- marker.
II. Setting the equipment
• Set blade to correct position:
-Press quick release button and
bring blade housing close to
front panel (Picture 2).
