Working behaviour and working technique (10 – 14)
5.4

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 ap-
pliance. 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 (10 – 14)
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.
■
Stand so that the cut can preferably be per-
formed at an angle of 90° to the branch (10/
a).
■
Saw off thick branches in sections order to
have better control over the point of impact
(11/1).
■
Never saw into the bulge at the base of the
branch in order to improve wound healing
and prevent rotting (12).
■
Press (13/a) the pole-mounted pruner against
the branch (13/2) with the tree grip (13/1)
when sawing to stabilise it on the branch.
■
Make a relief cut (14/a) on the underside of the
branch before sawing off the branch (14/b).
This prevents the bark from being torn off and
prevents damage to the tree that heals only
very slowly. The relief cut should not be deep-
443448_a
er than 1/3 of the branch thickness to avoid
any trapping of the pole-mounted pruner.
■
Always pull the pole-mounted pruner out of
the branch with the saw chain rotating so that
it does not become trapped.

7 MAINTENANCE AND CARE

WARNING! Danger of lacerations. 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
rechargeable battery.
■
Always wear protective gloves during mainte-
nance, care and cleaning work.
■
Do not get the appliance wet or expose it to
moisture.
■
Clean plastic parts with a cloth and do not
use any cleaning agents or solvents.
■
Check the electrical contacts for corrosion,
clean with a fine wire brush if necessary and
then spray with a contact spray.

Saw chain and guide rail

7.1.1

Replacing the saw chain and guide rail

Replacing the saw chain and guide rail
The saw chain and guide rail are exposed to sig-
nificant wear. Change the saw chain and guide
rail immediately if correct function is not assured.
7.1.2

Turning the guide rail

In order to avoid one-sided wear on the guide
rail, turn it every time the chain is changed.
7.1.3

Sharpening the saw chain

CAUTION! Risk of injury due to kickback.
Damaged or incorrectly sharpened saw chains in-
crease the danger of kickback! This can result in
injuries.
■
Clean the saw chain regularly.
■
Check the saw chain regularly for damage
and replace if necessary.
■
If you are not familiar with sharpening the
chain: Contact our relevant customer service.
The saw chain must be resharpened in the fol-
lowing cases:
■
Only sawdust is ejected instead of wood
chips.
■
The pole-mounted pruner must be forced
through the wood during pruning.
