Installation; Bench Mounting; Functional Description - Makita LS1214 Instruction Manual

28. Connect miter saws to a dust collecting device
when sawing.
29. Select saw blades in relation to the material to be
cut.
30. Take care when slotting.
31. Replace the kerf board when worn.
32. Do not use saw blades manufactured from high
speed steel.
33. 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 and,
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies,
depending 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 microscopic particles.
34. To reduce the emitted noise, always be sure that
the blade is sharp and clean.
35. The operator is adequately trained in the use,
adjustment and operation of the machine.
36. Use correctly sharpened saw blades. Observe the
maximum speed marked on the saw blade.
37. Refrain from removing any cut-offs or other parts
of the workpiece from the cutting area whilst the
tool is running and the saw head is not in the rest
position.

INSTALLATION

Bench mounting

When the tool is shipped, the handle is locked in the
lowered position by the stopper pin. Release the stopper
pin by lowering the handle slightly and pulling the stopper
pin. (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.
(Fig. 2)

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)
When lowering the handle, the blade guard rises
automatically. The blade guard returns to its original
position when the cut is completed and the handle 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 operation of
14
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 and/or
workpiece 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.
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
service center for a new guard. DO NOT DEFEAT OR
REMOVE GUARD. (Fig. 4)
Positioning kerf board (Fig. 5 & 6)
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 (2 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
knob which secures the 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.
CAUTION:
• Before and after changing the bevel angle, always
adjust the kerf boards as described above.
Maintaining maximum cutting capacity
This tool is factory adjusted to provide the maximum
cutting capacity for a 305 mm saw blade.
When installing a new blade, always check the lower limit
position of the blade and if necessary, adjust it as follows:
(Fig. 7 & 8)
First, unplug the tool. Push the carriage toward the guide
fence fully and lower the handle completely. 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
