distance from the ground. No adjustment is necessary
for standard installation.

wrench.
2. Move the skid plates (A) up or down.
a) On flat surfaces set the distance between the
scraper bar and the ground to 5-6 mm (0.2-0.25
in).
b) On rough surfaces set the skid plates (A) in a
position where the scraper bar is above the top
of the ground.
WARNING: Make sure that gravel
and stones do not go into the
product. Objects that eject at high
speed can cause injury.
