8 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.
Repairs are only allowed to be performed by
qualified specialists, and with the exclusive use of
genuine spare parts.
■
After each use, check the tool for wear and
replace any damaged components.
■
Do not expose the tool to rain or moisture.
Clean plastic parts with a cloth and do not
use any cleaning agents or solvents.
■
Clean the cooling air slots if they are blocked.
■
Do not spray the tool with water and do not
use a high-pressure cleaner.
8.1

Checking the saw chain lubrication

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 tool.
2. Hold the tip of the chain bar 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 tool and the groove of the chain bar.
If this is not successful, please contact our cus-
tomer service.
8.2

Checking the saw 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 occur when
handling the saw chain. Before all work with the
saw chain, heed the following:
■
Switch off the appliance and remove the re-
chargeable 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
chain bar and can be pulled though easi-
ly by hand. At operating temperature, the
saw chain stretches and hangs down.
■
The drive links of the saw chain must not
come out of the groove on the underside
of the chain bar – otherwise the saw
chain could jump off.
2. Re-tension the saw chain if necessary (see
chapter 8.3 "Tensioning and slackening the
saw chain (15)", page 36).
8.3 Tensioning and slackening the saw
chain (15)
1. Tension the saw chain; use the screwdriver
on the Allen key:
■
Tensioning the saw chain: Turn the chain
tensioning screw (15/1) in clockwise di-
rection (15/a).
■
Slackening the saw chain: Turn the chain
tensioning screw in anti-clockwise direc-
tion (15/b).
2. Check the chain tension(see chapter 8.2
"Checking the saw chain tension", page 36).
Repeat the previous step if necessary.
8.4 Replacing the chain bar and saw chain
(16 – 20)
If the cutting performance decreases, the saw
chain and possibly the chain bar must be re-
placed. The chain bar must be replaced if there
are clear signs of wear on the guide groove for
the saw chain.
Only OEM spare parts may be used (see Techni-
cal data).
CAUTION! Risk of injury on the saw
chain. The cutting edges of the saw chain are
very sharp so that cutting injuries can occur when
handling the saw chain. Before all work with the
saw chain, heed the following:
■
Switch off the appliance and remove the re-
chargeable battery.
■
Wear protective footwear.
