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.
Filling the chain oil tank
1. If necessary, clean the area around the filling hole of
sawdust and dirt.
2. Remove the chain oil tank cap.
Illustration D
3. Fill the chain oil into the tank. Check the filling level
of the chain oil on the sight glass and make sure that
the chain oil tank is filled to the maximum below the
filling hole.
Illustration E
4. Wipe up any spilled chain oil with a cloth.
5. Close the chain oil tank cap.
Checking the chain tension

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.
