',heck ftem
Is the saw blade installed correctly ?
*Is the saw blade tip contacting the turn base
when the blade is fulfy lowered?
Does the safety cover operate smoothly when you raise
and lower the head with the operating handle ?
•Is the m_ter €!amp grip tightened firmly ?

BI Set the miter saw on alevel bench, sturdy stand or table. If you intend to use the to
in just one spot, fasten it securely by means of bolts in tile four mounting feet.
Always obtain asteady base for safe, sure cutting action.
4. This miter saw is equipped with alocking stopper which is used to keep the head
the lowered position. To release from the hold-down position, lower the operati
handle to the release position. To lock the head in the hold-down posLtion, lower :
operation handle fully and turn the lever on the stopper to the hold position.

HOW TO USE YOUR MAKITA
MITER SAW
1. Installing saw blade
To replace the saw, raise the center cover.
Press the shaft lock and use the socket
wrench provided to loosen the hex bolt
which serves to hold the saw blade in place.
Then r_move the outer flange and instaff
the saw blade on the arbor shaft inside the
safety cover.

2. Switch action
There is a lock-off switch button on the
handle. To start the tool, first depress the
lock-off switch button and then pull the
trigger. Release the trigger to stop. The
trigger will not work before the lock-off
switch button is depressed. Form habit
of taking off the lock-off switch button,
when not in use.

3. Adjusting vertical position of blade
The miter saw is factory-adjusted with a
standard blade cutting depth for a 355 mm
(14") saw blade. Thus. IF YOU ARE NOT
USING ASTANDARD SAW BLADE,
loosen the hex nut.on the end of the gear
housing and use a minus (-) screwdriver to
turn the cutting depth adjustment bolt to
the right, Adjust so that when the operat-
ing handle is in the fully lowered posit_on
there willl be a distance of about 152 mm
3") from the front face of the guide fence
(guide rule) to the point where the front
edge of the blade .enters the kerf. (See
photo at below.) This wit1 produce the
correct depth adjustment. Then tighten
the hex nut,
4. Safety cover
(Prevents contact with blade)
-he see-through safety cover (lower blade
guard) raises as the work is contacted and
cutting begins, and it returns to its original
position when cutting is completed, Never
lock the guard at a fixed position. Always
use the guard in the freely telescoping con-
d_tion for your personal safety, Any irregu-
lar operation of the safety guard should be
corrected promptty. Never use the miter
saw with a faulty guard.

*If the see-through guard becomes dirty or sawdust adheres in such a way that the blade*
and/or work may not be easily visible, clean it off carefuEly with a damp cloth.
ALWAYS UNPLUG THE TOOL before you perform any cleaning.

5.Positioningformiterangle

2.Pressdownwithyourthumbonthe
knockspring as shown in Fig. 7. This
releases the knock pin and allows the
turn base (table) to turn freely.
3. When you have moved the grip to the
position where the arrow (pointer) in-
dicates the desired angle on the miter
gauge indication plate, releasc your
thumb from the knock spring and twist
the grip to the right to fasten securely.
4, The following settings are possible: 0,
15, 22.5, 30 and 45 degrees.
6. Alignment
This Makita Miter Saw was carefully adjusted and aligned at the factory but, rough handl-
ing during shipment may have affected the alignment. If your miter saw is not aligned
properly, perform the following.
•When Seriously Misaligned (Adjusting Fence)
After zeroing the miter pointer (as shown above) and carefully tightening the miter
clamp grip, loosen the four hex bolts holding the guide fence and reposition the fence
so that it will be square in relation to the saw blade. This can be done by placing'a
square or triangular rule against the saw blade and adjusting the fence so that the side
contacting the work is absolutely flush with the square or rule. Then, carefully replace
the hex bolts and fasten the fence securely. Failure to fasten securely will cause the
guide fence to move when a workpiece is pressed up against it by powerful vise action,
and thus accuracy will be compromised.
• When Slightly Misaligned (Adjusting Pointer)
Loosen the miter clamp grip and place a square or triangular rule against the side of the
guide fence and saw blade so as to square the blade to the fence. When this isdone and
you notice that the pointer on the miter angle indicator is not at zero on the miter scale,
gently tighten the miter clamp grip and then loosen the two pan head screws holding the
miter angle indicator plate. Adjust so that the pointer will be at zero; then retighten
timetwo screws to fasten the plate in place.

To attach the dust bag, fit it onto the
elbow and turn to the left to lock in piace;
it releases to the right.
When the hag is about half full. just unzip
the fastener below and empty it, slapping it
lightly so asto remove partlcles adhering to
"the insides which might hamper collection.

8, Tips on cutting
This tool is equipped with an electric safety brake which stops the saw blade within th
seconds from the moment you release the switch in the operating handle. This safe
feature can also be used to advantage, for example, in cutting certain materials llke lig
aluminum or plastics where special shapes are required, or in edge cuts in wood wh(
only a little stock is cut off. In this case. the saw blade isretracted after the blade stol
and the cut end w{ll not be contacted by a spinning blade as in aregular saw. Thus
cleaner -- as well as safer - cut is possible. •
JAIways keep the table top clear of chips, small pieces and so on in order to maintai
safe, clean surface.
9. Factory-adjusted lock nut
The hex lock nut holding together the gear
housing and arm has been factory-adjusted
to assure smooth arm action up and clown
and to guarantee precise cutting. Do not
tamper with it.
Should looseness develop at the housing
and arm connection, perform the followlng
adjustment. Work the arm vertically while
tightening the hex lock nut: the best posi-
tion to fasten the nut is just before the
motor body weight is obvious. Arm
if the nut is too loose, the cutting accuracy will be affected; if it is too tight, it wi
hard to work the arm up and down easily. Note that this is a self locking nut; it
special type that does not remove in the usual manner, and so it should not be
tightened or replaced with other types.

10.Installingholdersandsetplate
(Optionalaccessories)
They can be installed on either side to
serve as convenient means to hold long
work or work to be cut continuously into
fixed lengths. Fit the set plate on the
holder so that the fiat side of the plate is
on the inside. Wlth the curved portion
pointing up, then slip the holder rods into
the holes for them on the base (side).
Fasten securely with the wing boJt.

11. Positioning workpiece
To cut fixed lengths of anywhere from
250 mm (approx. 10") to 400 mm (15.7°').
align the cutting line on your workpiece
with the saw blade and position the set
plate on the holder so that its flank is flush
with the workplece, using the knob to re.
lease and fasten the set prate, Thus, the set
plate makes continuous cutting of specified
lengths both quick and convenient. If the
set plate is not required, simply loosen the
knob and draw it out of the way.
12, Fastening workplace
A workpiece should be grip only with a vise (Optional accessory'). Stock may be used to
prevent bendlng of thin aluminum extrusions when intricate cuts are done under gripping
by the vise. The vise can be attached on either side of the base. Use the socket wrench
provided to tighten its hex bolt securely.

changed at the same time.
•Oiling
Clean the tool thoroughly after use.
Apply oil to all sliding surfaces, the base and saw blade as arust inhibitor.
