WARNING
NOTICE
• The dimensions in figure 6.1.1 are factory
preset and the leveling linkage should not
need adjusting. After some time the
linkage may require some adjusting. If it
is required, only make adjustments on the
adjusting connector (E Fig. 6.1.1).
1. With the unit on a level surface
(recommend concrete surface), place
cardboard underneath all three of the
cutting heads.
2. An additional person is needed to stand 3
meters in front of the unit to check on how
level the front heads are when lowering.
Lower the cutting heads and ensure the
entire width of the front heads are parallel
with the level surface as the heads touch
the cardboard.
3. If they do not touch evenly, make an
adjustment using the adjusting connector.
Repeat procedure as needed until the two
front heads touch evenly on the level
surface.
