The saw chain may become loose after use.
From time to time check the saw chain
tension, certainly before each use.
a. Remove the battery.
b. Loosen the head screw (16) a bit to
loosen the sprocket cover lightly.
c. Adjust the chain tension. Turn the chain
adjusting screw (7) clockwise to
tighten, turn it counter-clockwise to
loosen. Tighten the saw chain so that
the gap between the centre of the lower
side of the guide bar and the saw chain
becomes approximately 3 – 4 mm.
d. Tighten the head screw (16) to secure
the sprocket cover.
Switching ON and OFF
8.6
The use of the Nexxsaw without lubricating
the chain with chain oil will damage the saw
chain and the guide bar.
a. Insert the battery into the battery
recess.
b. Hold the Nexxsaw firmly and securely
by the handgrip.
To switch on the Nexxsaw, first press
c.
the safety switch (1).
d. Then press the ON/OFF switch (10).
e. To switch off the saw, release the ON/
OFF switch.
Break-in time for new saw chains
8.7
a. Remove the battery and adjust the
chain tension.
b. Switch on the Nexxsaw and leave the
motor running idle for approx. 5
minutes.
c. Remove the battery and check the
chain tension again. If necessary,
re-tighten the chain.
d. Afterwards make only easy cuts for
approx. 30 minutes. Always ensure
sufficient lubrication of the saw chain!
Only use the Nexxsaw for heavier cuts
and greater cutting depths after the
running-in period has expired.
• Use only a sharp saw chain. A blunt saw
chain can jam more easily. Check the
chain tension more frequently when
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 guide bar. 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
8.8
• Never reach over the protection cover (4)
or under the base plate (8). There is a
risk of injury!
• Do not start the saw if the saw chain is in
contact with the workpiece, is in the
workpiece or can hit an object. This can
lead to serious 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
