English
The chain link spacing must be identical to the
chain sprocket pitch and the spacing of the
guide roller of the chain guide strip. The com­
plete cutting tool set consists of:
Chain sprocket [8-3]
–
Chain guide strip [2-4]
–
– Chain [2-3]
The service life of the cutting tool set primarily
depends on the lubrication and tension of the
chain. For this reason, the chain tension must
be checked and readjusted before starting work
and while working.
11.1 Chain tension
► With the chain sprocket cover [2-1] slightly
released, turn the tensioning wheel [2-9] in
the direction of the arrow until the bottom
of the chain is against the guide strip
(Fig. [10]).
► Then securely tighten the chain sprocket
cover [2-1] by turning the tensioning
wheel [2-2] clockwise.
► Check the correct chain tension by gently
pulling on the bottom of the chain (Fig. [10])
so that a gap of approx. 5 mm is created.
Once released, the chain must return to the ini­
tial position and be positioned right against the
guide strip.
NOTICE Chains that have been tensioned when
warm in the operating state must always be re­
leased after work is complete. When the ten­
sioned chain cools down, extreme shrinkage
stress occurs, which could damage the power
tool.
11.2 Sharpening the chain
If the chips are too fine (Fig. [11]), the chain
must be sharpened by an authorised service
workshop.
11.3 Chain lubrication
► Top up the oil if the oil level at the oil level
indicator [1-9] drops to the lower edge.
► Clean the area around the oil reservoir cap
carefully before opening the oil reservoir.
Any chips or dust that get into the oil reser­
voir will block the oil channels and there­
fore cause the chain lubrication to malfunc­
tion.
► Only use the oil to lubricate chainsaw
chains.
Used oil and oils not expressly designated
as chain oils must not be used. Biodegrada­
ble chain lubricating oils have a reduced lu­
bricating effect due to their composition and
32
can cause resinification in the inner lubrica­
tion channels after prolonged interruptions.
► If oil gets into the motor, contact the manu­
facturer or a service workshop (see sec­
tion 11).
► The oil reservoir capacity is 240 ml. To pre­
vent a high degree of wear, the chain and its
guide strip must be continuously lubricated
during operation. Lubrication is performed
by the oil feed pump, which supplies the
preselected oil quantity into the lubrication
groove on the guide strip.
11.4 Chain guide strip maintenance
► Uneven wear of the guide strip can be pre­
vented by always turning the guide strip
over after the chain is sharpened.
► Curved outer sliding surfaces (Fig. [9B]) are
considered normal wear and tear resulting
from operation. Remove protruding edges
on the guide rail with a flat file. .
► Wear to the inner guide surfaces (Fig. [9A])
occurs in the event of insufficient lubrica­
tion, incorrect chain lubrication or improper
operation. The guide strip must be re­
placed.
WARNING
Optimal chain guidance not ensured
Risk of injury from chain jumping off or
breaking
► The chain links must not touch the groove
base of the guide strip under any circum­
stances. If the chain touches the groove
base, the guide strip becomes worn and
must be replaced.
► The lubrication openings and the guide
strip groove must always be kept clean.
11.5 Chain sprocket maintenance
WARNING
Incorrect chain tension or late replacement
of chain sprocket
Risk of injury from chain jumping off or
breaking
► Replace the chain sprocket the second
time you replace the chain or before.
11.6 Replacing the chain and the chain guide
strip
► Align the power tool in the basic position at
0° and remove the chain sprocket cov­
er [2-1] by turning the tensioning
wheel [2-2] clockwise (Fig. [2]).
