usually, switch the engine off immediately
and check the machine.
■
A blocked angle-drive gearbox can cause
damage to the clutch.
■
The cutting line continues to turn after the
trimmer attachment has been switched off.
Consequently, wait until the line has stopped
before you switch the machine back on
again.
■
Change the cutting line when the spool is
empty.
7.1.2

Extending the cutting line (25)

NOTE The line cutter on the guard plate
shortens the line to the permitted length.
The cutting line shortens during operation and
frays out.
■
Tap (25/a) the spool head (25/1) on the
ground from time to time. This unwinds a
piece of new cutting line from the spool and
cuts off the used end of the cutting line
(25/2).

Working with brush cutter attachment

7.2.1

Avoiding kickback

■
Make sure you can stand securely. Keep
your feet apart at a comfortable distance, and
always be prepared for the possibility of kick-
back.
■
Before starting cutting, allow the cutting blade
to reach its full working speed.
7.2.2

Mowing

■
Angle the machine slightly forwards and
move it from right to left at an appropriate
and even speed. In this way, the cut material
will fall onto the area that has already been
mown.
■
Cut long grass and relatively dense vegeta-
tion in several passes. To do this, first trim
the upper part of the material being cut by
sweeping the machine to the right. Then
sweep the machine to the left in the opposite
direction and mow the lower part.
■
When working on a slope, proceed in strips.
Mow one strip parallel to the slope, then walk
back along the mown area and mow the next
strip.
■
Adapt the engine speed and the depth of cut
to the working conditions. If the engine in not
running fast enough, it is possible for under-
growth to get snagged or caught in the cut-
ting tool.

If grass, branches or other objects get caught
in the cutting tool or the machine vibrates un-
usually, switch the engine off immediately
and check the machine.
■
A blocked angle-drive gearbox can cause
damage to the clutch.
■
Never remove trapped cut material when the
cutting blade is still running. Consequently,
wait until the cutting blade has stopped.
■
If the cutting blade is blunt, broken or bent,
replace it with a genuine spare part.
7.3 Working with pole-mounted pruner
attachment
7.3.1 Avoiding kickback
When working with the saw of the pole-mounted
pruner, saw kickback can occur if the tool is not
used correctly. To avoid this:
■
Always hold the pole-mounted pruner firmly
with both hands.
■
Do not start the cut unless the saw chain is
running.
■
To allow better monitoring, saw with the bot-
tom edge of the guide rail. Always position
the pole-mounted 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 encoun-
ters a solid object in the wood.
■
Do not work unless the saw chain is correctly
sharpened and tensioned.
7.3.2

Checking the chain tension

CAUTION! Danger of injury due to the
saw chain jumping off! An insufficiently ten-
sioned saw chain can jump off during operation
and lead to injury.
■
Frequently check the chain tension. The
chain tension is too low if the drive links
come out of the groove on the underside of
the chain bar.
■
Re-tension the saw chain properly if the
chain tension is too low.
Frequently check the chain tension, because new
saw chains stretch.
1. Pull through the saw chain a little by hand
and, while doing so, check:
■
When cold: The saw chain has been ten-
sioned correctly when it can be lifted by
approx. 3 – 4 mm in the middle of the
