To adjust the skid plates
No adjustment is required for normal installation.
1. When the lock nut (B) is loose or the skid plate (A) is
not high enough from the ground, unlock the lock nut
(B) with a 13 mm open-ended wrench, to move the
skid plate up or down.
2. On flat surfaces, like asphalt roads, raise the skid
plates (A) 5-6 mm (0.2-0.25 in) off the ground. On
uneven surfaces, like gravel roads, make the
clearance between the ground and the product
larger with the skid plates to get the scraper bar
above the top of the gravel. Make sure that the
gravel and stones do not enter into the product. It
can cause personal injuries if objects are ejected at
high speed.
3. Tighten the lock nut (B).
