working with a new saw chain, as the
chain stretches more at first.
• The service life of a saw chain depends
on sufficient lubrication and the correct
tension.
• During operation, the chain heats up and
re-tensioning may be necessary. Relax
the chain after work so that it is not too
tight the next time the cold machine is
used.
• Do not re-tighten saw chains that have
become too hot. After it has cooled
down, it may contract and lie too tight
against the sword. Wait until the saw
chain has cooled down before
re-tensioning.
• The tension of the saw chain is impor-
tant for your safety and the function of
the machine. A correctly tensioned saw
chain increases the service life of the
machine.
• Check the chain tension before each use.
• The saw chain is correctly tensioned if it
can be pulled around the sword by hand
(wear protective gloves) without sagging.
• With new saw chains, you must readjust
the chain tension again after a short
period of operation.

Work instructions
• Never reach over the riving knife
(4)
or
under the base plate
(8)
. There is a risk
of injury!
• Do not cut if the saw chain is in contact
with the workpiece, is in the workpiece or
may hit an object. This can lead to seri-
ous injuries.
• Clamp loose workpieces before cutting
them. Remove foreign objects such as
nails, screws, etc.
• When cutting a branch that is under
tension be alert for spring back. When
the tension in the wood fibres is released,
the spring-loaded limb may strike the
operator and/or throw the Nexxsaw out
of control.
• Use extreme caution when cutting brush
and saplings. The slender material may
catch the saw chain and be whipped
toward you or pull you off balance.
•
When the saw chain is running, first
place the base plate
(8)
on the surface of
the workpiece and let the saw cut on its
own. Apply only light pressure to the
saw. The chain speed should not be
much slower.
10.10
Changing the saw chain
• Only handle the saw chain with gloves
and remove the battery first!
• Inspect the saw chain and the guide bar
for damage or signs of wear.
• Never put a new saw chain on a worn
guide bar.
•
Let each new saw chain break-in first!
• When attaching the saw chain, observe
the running direction!
10.11
Kickback
• The shape of the riving knife
(4)
largely
eliminates the risk of kickback.
• The saw is optimally protected against
kickback by the riving knife with tip pro-
tection. Never remove the riving knife
(4)
.
There is a risk of injury!
10.12
Sharpen the saw chain
• The saw teeth must be sharpened if the
sawdust becomes powdery, if additional
force is required for the incision, if a
straight incision is no longer possible or
if the vibrations become stronger.
• Blunt saw chains should be
re-sharpened.
• To sharpen the chain use a chain sharp-
ener, make sure you sharpen the chain at
a 30° angle.
• Or have the chain re-sharpened profes-
sionally (advised).
• Replace the saw chain if there is consid-
erable damage that cannot be repaired
by filing.
10.13
Cleaning the guide bar
(See
Fig. F
).
• Thoroughly clean the notch of the guide
bar.
• Replace the guide bar if the guide groove
is damaged or worn and the saw chain
has too much lateral space.
