, and
bearing in mind that each
 graduation of
the scale 
corresponds to a depth
 of 1cm.
Lower slowly to prevent the
 engine
stalling.
• Gently move the machine forward
ensuring that the front guide and the disc
are always aligned with the line marked
out.

bearing lubricant to the nipples in the
depth adjustment chassis (depending on
the frequency of use).

works at an angle, check it frequently in
the horizontal position that the oil level
is never below the second line on the
gauge.
