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

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.
