5.2

Checking the chain tension

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
guide rail and can be pulled though easily
by hand. At operating temperature, the
saw chain stretches and hangs down.
■
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.
2. Re-tension the saw chain if necessary (Ten-
sioning and slackening the saw chain (07)).
5.3

Checking the chain lubrication

Check the function of the automatic chain lubrica-
tion by switching on the polemounted pruner and
pointing its tip towards a piece of cardboard or
paper placed on the ground.
IMPORTANT!
Danger of damage to the appliance
Ground contact invariably leads to blunt-
ing of the saw chain.
■
Do not make contact with the ground
with the chain and maintain a safety
distance of 20 cm.
1. Switch on the appliance.
2. Hold the tip of the guide rail in the direction of
a cardboard box or paper on the ground.
■
If the check produces a growing trace of
oil, this indicates the automatic oiling
function is operating correctly.
■
If there is no trace of oil even though the
oil tank is full: Clean the oil entry hole in
the appliance and the groove of the guide
rail.
If this is not successful, please contact our cus-
tomer service.

6 WORKING BEHAVIOUR AND
WORKING TECHNIQUE (09 – 13)
WARNING!
Increased risk of falling
There is a greater risk of falling if work is
carried out from an elevated position
(e.g. ladder).
■
always work with the appliance from
the ground and make sure that you
are standing securely.
■
Heed the safety instructions.
■
Where possible, stand so that the cut can be
carried out at an angle of 90° to the branch
(09/a).
■
Saw off thick branches in sections in order to
have better control over the point of impact
(10/1).
■
Never saw in the flaring at the beginning of
the branch in order to improve the healing of
the wound and to avoid rot (11).
■
Press (12/a) the polemounted pruner against
the branch (12/2) with the tree grip (12/1)
when sawing to stabilise it on the branch.
■
Before the branch is sawn off (13/b), make a
relief cut (13/a) on the underside of the
branch. This can avoid the bark tearing off
and causing difficult-to-heal damage to the
tree. The relief cut should not be deeper than
1/3 of the branch thickness to avoid any trap-
ping of the polemounted pruner.
■
Always pull the polemounted pruner with ro-
tating saw chain out of the branch so that it
does not become trapped.

7 MAINTENANCE AND CARE

WARNING!
Danger of cutting injuries
Danger of cutting injuries when reaching
into sharp-edged, moving appliance
parts and into cutting tools.
■
Before maintenance, care and
cleaning work, always switch off the
appliance. Remove the recharge-
able battery.
■
Always wear protective gloves
during maintenance, care and clean-
ing work.
