Mounting the saw chain
9.8
(See Fig. C, D, E).
Always wear gloves when handling the
saw chain.
a. Unscrew the head screw (4) coun-
ter-clockwise in order to remove the
sprocket cover (5).
b. Remove the guide bar from the machine
and run the saw chain around it.
Please note the running direction of the
saw chain. The saw chain icon is shown
on the cover.
c.
Run the saw chain over the sprocket
(22) and replace the guide bar on the
chain adjusting screw pin (21).
d. Use an oiler to oil the saw chain and the
sprocket.
e.
Slightly tighten the saw chain with the
chain adjusting screw (15). Use the
included adjustment key (20) to tighten
the screw. For tightening, turn the screw
clockwise.
f.
Re-tighten the sprocket cover (5) with
the head screw (4) on the housing.
Chain lubricating oil
9.9
• Only use commercially available, biode-
gradable chain oils.
• Do not use engine oil, waste oil or other
mineral oils.
• If the saw makes a rattling noise, the
chain must be lubricated.
Adjusting saw chain tension
9.10
(See Fig. C).
CAUTION: Do not tighten the saw chain too
much. Excessively high tension of saw
chain may cause breakage of saw chain,
wear of the guide bar and breakage of the
sprocket.
CAUTION: A chain which is too loose can
jump off the guide bar.
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 (4) a bit to
loosen the sprocket cover lightly.
c.
Adjust the chain tension. Turn the chain
adjusting screw (15) 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 (4) to secure
the sprocket cover.
Switching ON and OFF
9.11
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.
c.
To switch on the Nexxsaw, first press
the safety switch (7).
d. Then press the ON/OFF switch (8).
e.
To switch off the saw, release the ON/
OFF switch.
Break-in time for new saw chains
9.12
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
