21. Stop operation immediately if you notice anything
abnormal.
22. Do not attempt to lock the trigger in the ON position.
23. Be alert at all times, especially during repetitive,
monotonous operations. Don't be lulled into a false
sense of security. Blades are extremely unforgiving.
24. Always use accessories recommended in this man-
ual. Use of improper accessories such as abrasive
wheels may cause an injury.
25. Do not use the saw to cut other than aluminum,
wood or similar materials.
26. Connect miter saws to a dust collecting device
when sawing.
27. Select saw blades in relation to the material to
be cut.
28. Take care when slotting.
29. Replace the kerf board when worn.
30. Do not use saw blades manufactured from high
speed steel.
31. Some dust created from operation contains
chemicals known to cause cancer, birth defects
or other reproductive harm. Some examples of
these chemicals are:
• lead from lead-based-painted material
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depend-
ing on how often you do this type of work. To
reduce your exposure to these chemicals: work
in a well ventilated area and work with approved
safety equipment, such as those dust masks
that are specially designed to filter out micro-
scopic particles.
32. To reduce the emitted noise, always be sure that
the blade is sharp and clean.
33. The operator is adequately trained in the use,
adjustment and operation of the machine.
34. Use correctly sharpened saw blades. Observe
the maximum speed marked on the saw blade.
35. Refrain from removing any cut-offs or other
parts of the workpiece from the cutting area
whilst the machine is running and the saw head
is not in the rest position.
SAVE THESE INSTRUCTIONS.
INSTALLATION
Bench mounting
When the tool is shipped, the handle is locked in the low-
ered position by the handle latch. Release the handle
latch by lowering the handle slightly and turn the handle
latch to the released position. (Fig. 1)
This tool should be bolted with four bolts to a level and
stable surface using the bolt holes provided in the tool's
base. This will help prevent tipping and possible injury.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Blade guard
(Fig. 3 & 4)
When lowering the handle, the blade guard rises auto-
matically. The guard is spring loaded so it returns to its
original position when the cut is completed and the han-
dle is raised. NEVER DEFEAT OR REMOVE THE
BLADE GUARD OR THE SPRING WHICH ATTACHES
TO THE GUARD.
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.
NEVER USE THE TOOL IF THE BLADE GUARD OR
SPRING ARE DAMAGED, FAULTY OR REMOVED.
DOING SO IS HIGHLY DANGEROUS AND CAN CAUSE
SERIOUS PERSONAL INJURY.
If the see-through blade guard becomes dirty, or sawdust
adheres to it in such a way that the blade is no longer
easily visible, unplug the saw and clean the guard care-
fully with a damp cloth. Do not use solvents or any petro-
leum-based cleaners on the plastic guard.
If the blade guard is especially dirty and vision through
the guard is impaired, use the supplied socket wrench to
loosen the hex bolt holding the center cover.
Loosen the hex bolt by turning it counterclockwise 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 discolored
through age or UV light exposure, contact a Makita ser-
vice center for a new guard. DO NOT DEFEAT OR
REMOVE GUARD.
Kerf board (Fig. 5)
This tool is provided with the kerf board in the turn base
to minimize tearing on the exit side of a cut. If the kerf
groove has not yet been cut in the kerf board by the fac-
tory, you should cut the groove before actually using the
tool to cut a workpiece. Switch on the tool and lower the
blade gently to cut a groove in the kerf board.
Maintaining maximum cutting capacity
This tool is factory adjusted to provide the maximum cut-
ting capacity for a 355 mm saw blade.
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 handle completely.
Loosen the hex nut at the rear of the gear housing. Use a
screwdriver 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 adjusting, tighten the hex nut with the wrench while
carefully holding the adjusting bolt in position with the
screwdriver.
