Blade guard (Fig. 3 & 4)
When lowering the handle, the blade guard rises auto-
matically. The blade guard returns to its original position
when the cut is completed and the handle is raised.
WARNING:
• Never defeat or remove the blade guard or the
spring which attaches to the guard. An exposed
blade as a result of defeated guarding may result in
serious personal injury during operation.
In the interest of your personal safety, always maintain
the blade guard in good condition. Any irregular opera-
tion of the blade guard should be corrected immediately.
Check to assure spring loaded return action of guard.
WARNING:
• Never use the tool if the blade guard or spring are
damaged, faulty or removed. Operation of the tool
with a damaged, faulty or removed guard may result in
serious personal injury.
If the see-through blade guard becomes dirty, or sawdust
adheres to it in such a way that the blade and/or work-
piece is no longer easily visible, unplug the saw and
clean the guard carefully with a damp cloth. Do not use
solvents or any petroleum-based cleaners on the plastic
guard because this may cause damage to the guard.
If the blade guard becomes dirty and needs to be
cleaned for proper operation follow the steps below:
With the tool switched off and unplugged, use the sup-
plied socket wrench to loosen the hex bolt holding the
center cover. Loosen the hex bolt by turning it counter-
clockwise and raise the blade guard and center cover.
With the blade guard so positioned, cleaning can be
more completely and efficiently accomplished. When
cleaning is complete, reverse procedure above and
secure bolt. Do not remove spring holding blade guard. If
guard becomes damaged through age or UV light expo-
sure, contact a Makita service center for a new guard.
DO NOT DEFEAT OR REMOVE GUARD.
Positioning kerf board (Fig. 5, 6 & 7)
This tool is provided with the kerf boards in the turn base
to minimize tearing on the exit side of a cut. The kerf
boards are factory adjusted so that the saw blade does
not contact the kerf boards. Before use, adjust the kerf
boards as follows:
First, unplug the tool. Loosen all the screws (3 each on
left and right) securing the kerf boards. Re-tighten them
only to the extent that the kerf boards can still be easily
moved by hand. Lower the handle fully and push in the
stopper pin to lock the handle in the lowered position.
Loosen the locking screw counterclockwise which
secures the upper slide poles and also push forward the
lock lever which secures the lower slide poles. Pull the
carriage toward you fully. Adjust the kerf boards so that
the kerf boards just contact the sides of the blade teeth.
Tighten the front screws (do not tighten firmly). Push the
carriage toward the guide fence fully and adjust the kerf
boards so that the kerf boards just contact the sides of
blade teeth. Tighten the rear screws (do not tighten
firmly).
After adjusting the kerf boards, release the stopper pin
and raise the handle. Then tighten all the screws
securely.

NOTICE:
• After setting the bevel angle ensure that the kerf
boards are adjusted properly. Correct adjustment of
the kerf boards will help provide proper support of the
workpiece minimizing workpiece tear out.
Maintaining maximum cutting capacity
(Fig. 8, 9 & 10)
This tool is factory adjusted to provide the maximum cut-
ting capacity for a 305 mm saw blade.
Unplug the tool before any adjustment is attempted.
When installing a new blade, always check the lower limit
position of the blade and if necessary, adjust it as follows:
First, unplug the tool. Lower the stopper lever to position
the saw blade as shown in the figure. Push the carriage
toward the guide fence fully and lower the handle com-
pletely. Use the socket wrench to turn the adjusting bolt
until the periphery of the blade extends slightly below the
top surface of the turn base at the point where the front
face of the guide fence meets the top surface of the turn
base.
With the tool unplugged, rotate the blade by hand while
holding the handle all the way down to be sure that the
blade does not contact any part of the lower base. Re-
adjust slightly, if necessary.
After adjustment, always return the stopper lever to the
original position by turning it counterclockwise.
WARNING:
• After installing a new blade and with the tool
unplugged, always be sure that the blade does not
contact any part of the lower base when the handle
is lowered completely. If a blade makes contact with
the base it may cause kickback and result in serious
personal injury.
Stopper arm (Fig. 11)
The lower limit position of the blade can be easily
adjusted with the stopper arm. To adjust it, rotate the
stopper arm in the direction of the arrow as shown in the
figure. Adjust the adjusting screw so that the blade stops
at the desired position when lowering the handle fully.
Adjusting the miter angle (Fig. 12)
Push the grip so that the cams engages and turn it clock-
wise until it stops. Turn the turn base while pressing
down the lock lever. When you have moved the grip to
the position where the pointer points to the desired angle
on the miter scale, turn the grip 90° counterclockwise to
lock the turn base.
CAUTION:
• After changing the miter angle, always secure the turn
base by turning the grip 90° counterclockwise.
NOTICE:
• When turning the turn base, be sure to raise the handle
fully.
Adjusting the bevel angle (Fig. 13, 14 & 15)
To adjust the bevel angle, loosen the lever at the rear of
the tool counterclockwise. Push the latch lever forward as
shown in the figure fully while supporting the weight of
the saw head so as to release the pressure on the lock
pin.
When tilting the carriage to the right, tilt the carriage to
the left slightly after loosening the lever and press the
releasing button. With the releasing button being
pressed, tilt the carriage to the right.
