To reverse the cutting head (K 770, K
770 OilGuard, K 770 Rescue)
WARNING: Only cut with the cutting head
reversed if a standard procedure is not
possible.
The product has a reversible cutting head that lets you
cut near a wall or at ground level. Only cut with the
cutting head reversed if a standard procedure is not
possible. If a kickback occurs, it is more difficult to
control the product if the cutting head is reversed. The
distance between the cutting blade and the center of the
product is longer, which means that the handle and the
cutting blade do not align. This has a negative effect on
the balance in the product and it is more difficult to hold
