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).

• Set clamping carriage in lower
position:

- Loosen twist grip knob.

- By pressing against the twist

grip knob, allows free movement
of the clamping carriage. Move
down clamping carriage
(Picture 3).

• Set blade housing to scraping
length required (single or double
scraping length).

-Press quick release button and

set blade housing roughly to
relevant dimension marking
(Picture 2). The blade housing
will end up on the left of the
marking.

- The position of the blade hous-

ing will be fine tuned by turning
the roller handle until the
marking line chosen as the
dimension range is flush with the
blade housing (Picture 4).

III. Mounting of scraper

• Move scraper across pipe in such
a way that the clamping carriage
is inside the pipe and the scraper
blade is on the surface of the
pipe (Picture 5). The housing
must be flush with the front edge
of the pipe.

Attention!
Do not run the blade over the
pipe surface.

• Setting the clamping carriage.

- Move the clamping carriage

upwards until it is in contact
with the pipe wall (Picture 3).

The supporting arm of the

clamping carriage should be
roughly parallel to the pipe wall.

- Tighten twist grip knob

(Picture 6) until all four guide
rollers rest on the pipe surface.

IV. Scraping of pipe surface

•Turn equipment clockwise around
the pipe end. By turning steadily,
the pipe can be scraped up to the
pipe end (Picture 7).

Attention!
During scraping, the scraper
must be pushed against the pipe
end in order to avoid axial tilting!

V. Dismantling of the equipment

• Loosen twist grip knob and
remove scraper from pipe.

• In order to prevent injuries or
scraper damage, the blade
housing should be moved up to
the front plate on completion.

VI. Preparing the fusion process

• Remove the swarf.

• Check scraping result.

If marking has not been completely
removed, the scraping process has
to be repeated from Point III.

• Apply a chamfer (about 0.08" –

0.11") at the end of the pipe
using a hand held scraper.

• Clean the pipe before fusion
using PE cleaner with an
absorbent, non-fibrous and
undyed paper.

• Processing the FRIALEN®/
FRIAFIT® -coupler takes place
according to the installation
instructions.

Attention!
The scraper must be kept clean
and dry and always stored in its
transporting case.
