Tensioning The Saw Chain; Sawing Techniques - Parkside Performance Ppksa 40-Li B2 Originalbetriebsanleitung

Prior to changing the saw chain, the groove
of the guide rail must be cleaned of dirt be-
cause dirt deposits available can cause the
saw chain to break out of the rail. The de-
posits can also absorb the chain oil. The res-
ult would be that the chain oil does not reach
the underside of the rail – or only does so to
a limited extent – thereby reducing lubrica-
tion.

Tensioning the saw chain

NOTICE! Do not re-tension or change the
saw chain when it is hot because it shrinks
slightly once it has cooled down. If this is not
observed it can lead to damage on the guide
rail or the engine because the saw chain is
now too taut on the blade bar.
Regularly tightening the saw chain provides
safety for the user and reduces and/or pre-
vents wear and chain damage. We recom-
mend that the user check the chain tension
before starting work and at intervals of ap-
prox. 10 minutes and correct it if necessary.
The saw chain warms up when working with
the saw and thus expands slightly. These
"expansions" can be expected especially
from newer saw chains.
Chain tension and chain lubrication have a
significant impact on the service life of the
saw chain. The chain tension of a new saw
chain must be readjusted after a maximum
of 5 cuts.
The saw chain is properly tensioned when
it does not hang from the underside of the
blade bar and cannot be moved around by a
gloved hand. When pulling on the saw chain
with 9 N (approx. 1 kg) of force, the saw
chain and blade bar should not be separated
by a distance of more than 2 mm.
CAUTION! Risk of injury due to uninten-
tional start-up. Switch off the machine. Re-
move the batteries from the tool.
Procedure (Fig. C)
1. Make sure that the chain brake is re-
leased, i.e. the chain brake lever (5) is
pulled against the front handle (4).
2. Undo the wing nut (12) ⭯ .
3. To tension the saw chain, turn the chain
tensioner screw (13) ⭮ .
To loosen the tension, turn the chain ten-
sioner screw (13) ⭯ .
4. Retighten the wing nut (12) ⭮ .
The chain tension of a new saw chain must
be readjusted after a maximum of 5 cuts.

Sawing techniques

WARNING! Risk of injury! If the saw
chain is jammed, do not try to pull the chain-
saw out by force. Switch off the engine, re-
move the batteries and use a lever arm or
wedge to release the chainsaw.
• Always stand above the tree trunk when
sawing on slopes.
• Remove dirt, stones, loose bark, nails,
clips and wires from the tree.
• The saw chain must not touch the ground
or any object while sawing through the
material or thereafter.
• You will have better control over the
device if you saw using the lower edge
of the blade bar (saw chain in pulling dir-
ection) and not using the upper edge of
the blade bar (saw chain in pushing direc-
tion).
• Ensure that the saw chain does not get
stuck while sawing. The log must not
break or splinter.
• Please observe the precautionary meas-
ures to protect against kickback (Causes
and Operator Prevention of Kickback,
p. 36)
• Reduce the contact pressure towards the
end of the cut without loosening the firm
grip on the chainsaw handles in order
to maintain full control at the moment of
"sawing through".
• After completing the cut, wait until the
chainsaw has come to a standstill before
removing it.
• Always switch off the chainsaw engine
before moving from tree to tree.
Felling trees
WARNING! A lot of experience is needed
to fell trees. Only fell trees if you know how
to use the chainsaw safely. Never use the
chainsaw if you feel unsafe.
CAUTION! Do not cut down a tree if
there is a strong or changing wind, if there
