Turn the chain tightener
(W6)
to
the right (clockwise)
until the chain engages the guide groove
of
the bottom side
of the bar (see circle). Press the guide bar against the
housing with your left hand.
Tightening the saw chain
-
Slightly lift the end of the guide bar and turn the chain
adjusting screw
(116)
to
the right (clockwise) until the chain
rests against the bottom side of the guide bar.
While still holding up the tip of the guide bar, tighten the
retaining nuts
(W3)
with the universal wrench.

Checking the chain tension
-
The tension of the chain is correct
if
the chain rests against
the bottom side
of
the guide bar and can still be easily
turned by hand. While doing
so
the chain brake must
be
released.
Every new chain has
to
be broken in for about
2
to
3
minutes. Ample chain lubrication is essential during this
period. After breaking in, check chain tension and adjust,
if
necessary.
When checking the chain tension the engine must
be
NOTE:
Check the chain tension frequently

chains tend to
get longer during use!
If
this is not done, there is a risk
of
the
chain jumping
off
the bar.
It
is recommended to use
2-3
chains altematively.
In order
to
guarantee uniform wear of the guide bar the bar
should
be
turned over whenever replacing the chain.

The MAKITA models comes with an inertia chain brake as
standard equipment.
If
kickback occurs due
to
contact of the
guidabar tip with wood
(see
SAFETY PRECAUTIONS), the
chain brake will stop the chain through inertia
if
the kickback is
sufficiently strong. The chain will stop within a fraction of a
second.
The chain brake
Is
installed
to
block the
saw
chain before
starting it and
to
stop
it immediately in
case
of
an emergency.
Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of the
guide bar combined with the inertia of the hand guard
(U3)
will
automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand guard
(U3)forward(towardsthetipofthesaw)withyourlefthand(arrow
1).
Releasing the chain brake
Pull the hand guard
(u3)
towards you (arrow
2)
until
you
feel
it
catch. The brake is now released.
