WARNING! Always use a saw chain designed as “low-
kickback” or a saw chain which meets the low-kickback
requirements! A standard saw chain (a chain which does
not have the kickback reducing guard links) should only be
used by an experienced professional operator!
Nevertheless, a low-kickback saw chain does not
completely eliminated kickback! A low-kickback or “safety”
chain should never be regarded as complete protection
against injury! Therefore always use a low-kickback saw
chain in conjunction with other kickback protection devices
> Replace the cover (10) and
slightly tighten the retaining nut (9)
clockwise with the wrench (8) (Fig.
7). Do not tighten the locking nut
completely; saw chain tensioning is

After
initial operation, new chains can lengthen considerably. This is
normal during the break-in period and the interval between future
adjustments will lengthen quickly.

NOTE: The saw chain (4) has not yet been tensioned.
Tension the chain as described under “Saw chain
tensioning”. After operating the product for approximately 1
hour, adjust the chain tension again.
WARNING! Unplug the product from the power source
before adjusting the saw chain tension!
The cutting edges of the saw chain are sharp. Always wear
protective gloves when handling the chain!
Always maintain proper chain tension! A loose chain
increases the risk of kickback! A loose chain may jump out
of the guide bar groove! This may injure the operator and
damage the chain! A loose chain will cause rapid wear to the
chain, guide bar and sprocket!
Tensioning the chain too tightly will overload the motor and
cause damage, and insuf
¿
cient tension can cause chain
derailing, whereas a correctly tightened chain provides the
best cutting characteristics and prolonged working life! The
chain life mainly depends upon suf
¿
cient lubrication and
correct tensioning!

surface.
> Turn the tension screw (3)
clockwise until the chain “tie straps”
are just touching the bottom edge
of the guide bar (5) (Fig. 8).
> Turn the retaining nut (9) clockwise to
tighten the cover (10) completely,
and replace the red cap (Fig. 11)
> Check the chain tension using one hand to lift the saw chain (4)
against the weight of the product. The correct chain tension is
achieved when the saw chain can be lifted by approximately 2 -
4 mm from the guide bar (5) in the centre (Figs. 9, 10).
