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 (approx. + 0.1969 inches).
• 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
• Remove blade protective cap.
• Mount scraper tool.
• Guide the tool over the pipe (Figure 2) until the support rollers
(5) are
resting on the pipe (Figure 3) and are flush with its edge.
• Turn the twist grip knob
(2) clockwise by hand until the support rollers (5),
guide rollers
(6) are pressing against the pipe. If the pipe is oval this process
should be carried out on the smallest available outside diameter of the pipe.
