Preparation of scraping
• Remove any dirt such as sand and soil from the pipe surface to be scraped
(e.g. using a clean, fat-free cloth).
NOTICE
If the pipe surface to be scraped is not cleaned, the scraper blade wears
prematurely!
• Determine the area to be scraped (= the insertion depth of the coupler/
moulded part + 5 mm).
• Mark the area to be scraped with a FRIALEN marker pen using wavy lines
(this is for you to determine whether pipe has been scraped evenly).
4.
Assembly of the
scraper tool
• Set pipe dimension.
• Hold the scraper tool by the roller
handle (1) and point it towards the
floor.
• Turn the tool anti-clockwise with
twisting movements until it reaches
the mark for the required scraping
dimension (Fig. 2).
NOTICE
Damage of the scraper blade!
Do not allow the scraper blade (3) to butt at the clamping carriage (4).
