Inserting the carrying belt
The carrying belt helps to lower the device in a con-
trolled manner after cutting and to catch the weight of
the device during use.
Illustration C
1. Hook the carrying belt hooks into the eyelets on the
handle and shaft. Place the carrying belt over one
shoulder. Make sure that the carrying belt can be re-
leased quickly in the event of danger.

Working techniques

When pruning, proceed as follows:
 Place the bar on the branch to be cut and push the
device forward so that the end stop touches the
branch.
Illustration J
The device stabilizes during pruning and the cuts
are made cleaner.
 Where possible, maintain a distance of approx. 15
cm between the tree trunk and the cut.
 Cut small branches that are thin and light a single
cut with the bottom edge of the guide rail.
 Heavier branches of larger diameter may break or
splinter during pruning. Therefore, cut in several
steps:
a Make a cut in the underside of the branch with the
top edge of the guide rail. This cut should be
about one third of the branch diameter.
Illustration K
b Make a cut in the top of the branch.
c If another cut is necessary, never continue cutting
in an existing cut but rather start a new cut.
The following should be noted when pruning:
 Do not raise the bar higher than 60 ° from the hori-
zontal.
 Do not exert excessive force on the guide rail.
 Do not stand under the branch being sawn off.
 Make sure that the falling branch does not endanger
the user or spectators nor damage any objects.
 Maintain a safety distance of at least twice the
branch length when pruning. If this is not possible,
have the work done by a professional arborist.
