8 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 clean-
ing work, always switch off the appli-
ance. Remove the rechargeable bat-
tery.
■
Always wear protective gloves during
maintenance, care and cleaning
work.
8.1 Checking the chain tension
CAUTION!
Risk of injury on the saw chain
The cutting edges of the saw chain are
very sharp so that cutting injuries can oc-
cur when handling the saw chain. Before
all work with the saw chain, heed the fol-
lowing:
■
Switch off the appliance and remove
the rechargeable battery.
■
Wear protective footwear.
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 4.4 "Tensioning and slackening the
saw chain(09)", page37).
8.2 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 (Cleaning the guide rail).
If this is not successful, please contact our cus-
tomer service.
8.3 Saw chain and guide rail
8.3.1 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.
8.3.2 Turning the guide rail
In order to avoid one-sided wear on the guide
rail, turn it every time the chain is changed.
8.3.3 Sharpening the saw chain
CAUTION!
Risk of injury due to kickback
Damaged or incorrectly sharpened saw
chains increase 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 cus-
tomer service.
The saw chain must be sharpened in the follow-
ing cases:
■
Only sawdust is thrown out, rather than wood
chips.
■
The polemounted pruner must has to be
forced through the wood during pruning.
