Square and triangle scrapers and scrapers
The wood chipper is equipped with two square scrapers on the disc and a triangle scraper in the
disc housing.
The purpose of the square and triangle scrapers is to remove material that can get stuck by the
knives.
At the same time, the square scraper removes material which falls off in front of the disc.
This reduces fuel consumption and wear on the casing.
A square scraper can be reversed once, before being replaced, while the triangle scraper should
always be replaced when it is worn. The square scrapers belong together as a set and must always
be replaced in pairs.
Changing the square and triangle scrapers
1.
Open the disc housing as described in chapter 7.
2.
Remove the two square scrapers (1) and the four scrapers (2) and triangle scrapers (3).
3.
Reverse the square scraper (1) 180 degrees around the bolt hole, so that the worn corners
face in towards the disc's centre of rotation. If both corners or sides are worn, replace the
scrapers.
Reverse the scraper (2) 180 degrees so that the worn side faces into the disc's centre of
rotation. If both sides are worn, replace the scrapers.
The triangle scraper (3) cannot be reversed and must always be replaced.
4.
Clean the contact surfaces and the square and triangle scrapers (1, 3)/scrapers (2) and
re-fit.
5.
Finally, close the disc housing as described in chapter 7.
