Extending the cutting line
1. Run the engine at full speed and tap the spool on the
ground.
The line is automatically extended.
„
The knife (line cutter) on the guard plate shortens
the line to the permitted length.
Working with the polemounted pruner
When working with the saw of the polemounted pruner,
saw kickback can occur if the tool is not used correctly. To
avoid this:
Always hold the polemounted pruner firmly with both
„
hands.
Do not start the cut unless the saw chain is running.
„
To allow better monitoring, saw with the bottom edge of
„
the guide rail. Always position the polemounted pruner
as flat as possible when doing this.
Never saw with the tip of the guide rail.
„
Sawing with the top edge can cause the saw to kick
„
back if the saw chain jams or encounters a solid object
in the wood.
Do not work unless the saw chain is correctly
„
sharpened and tensioned.
Monitoring the chain tension
Frequently check the chain tension, because new saw
„
chains stretch.
When cold, the saw chain must be in contact with
„
the bottom edge of the guide rail, but it should still be
possible to pull it through by hand.
At operating temperature, the saw chain stretches and
„
hangs down.
IMPORTANT!
The drive links of the saw chain are not allowed
to come out of the groove on the underside of the
guide rail – otherwise the saw chain could jump off.
Re-tension the saw chain.
Guide rail: In order to avoid one-sided wear on the
guide rail, turn it every time the chain is changed.
1. To check, pull the saw chain through by hand a little
so that it makes correct contact on the chain sprocket
and in the guide rail.
The saw chain has been tensioned correctly when
it can be lifted by approx. 3 – 4 mm in the middle
of the guide rail and can be pulled though easily
by hand.
2. Re-tension the saw chain if necessary, see the
Tightening the saw chain section.

Working with the hedge trimmer
Hold the hedge trimmer at the required angle.
„
The maximum cutting diameter depends on the type
„
of wood, its age, moisture content and the hardness of
the wood. As a result, cut very thick branches back to
the appropriate length using pruning shears before you
start to trim the hedge.
The double-sided blade of the hedge trimmer can be
„
guided forwards and backwards, or swept from one
side to another with oscillating movements.
First cut the sides of the hedges and only after that do
„
the top.
Cut the hedge from the bottom upwards.
„
Cut the hedge in a trapezoidal shape. This prevents
„
foliage loss in the lower area of the hedge due to lack
of light.
Stretch a guideline along the length of the hedge if you
„
want to cut the top of the hedge level.
IMPORTANT!
Only use genuine cutting blades and accessories!
Non-genuine parts can lead to injuries and
malfunctions of the machine!

Maintenance and care

CAUTION!
Danger of injury due to rotating cutting tools!
Do not adjust Bowden cables unless the
„
engine is switched off.
Do not check the function unless the
„
trimmer is horizontal.
Cleaning the guard plate
1. Switch off the machine.
2. Use a screwdriver or a similar tool to remove mowing
residues carefully.
Clean the guard plate regularly in order to avoid
the split shaft overheating.
