Working behaviour and working technique (09 – 13)
5.1 Switching the appliance on and off
See "Multitool MT 40 – basic appliance" operat-
ing instructions.
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 (see
chapter 4.2 "Tensioning and slackening the
saw chain (07)", page 31
).
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 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 (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 cuts and lacera-
tions. Danger of cuts and lacerations 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.
