Operation - Makita LS1214LB Instruction Manual

Horizontal vise (optional accessory) (Fig. 34 & 35)
The horizontal vise can be installed in two positions on
either the left or right side of the base. When performing
15° or greater miter cuts, install the horizontal vise on the
side opposite the direction in which the turn base is to be
turned.
By flipping the vise nut to the left, the vise is released,
and rapidly moves in and out. To grip the workpiece,
push the vise knob forward until the vise plate contacts
the workpiece and flip the vise nut to the right. Then turn
the vise knob clockwise to secure the workpiece.
The maximum width of workpiece which can be secured
by the horizontal vise is 200 mm.
When installing the horizontal vise on the right side of the
base, also use the sub-fence R to secure the workpiece
more firmly. Refer to the "Sub-fence R" section described
on previously for installing the sub-fence R.
CAUTION:
• Always set the vice nut to the right fully when securing
the workpiece. Failure to do so may result in insufficient
securing of the workpiece. This could cause the work-
piece to be thrown, cause damage to the blade or
cause the loss of control, which can result in PER-
SONAL INJURY.
Holders (Fig. 36)
The holders can be installed on either side as a conve-
nient means of holding workpieces horizontally. Slip the
holder rods into the holes in the base and adjust their
length according to the workpiece to be held. Then
tighten the holders securely with the screws.
CAUTION:
• Always support long workpieces level with the top sur-
face of the turn base for accurate cuts and to prevent
dangerous loss of control of the tool.
Kerf block (optional accessory) (Fig. 37 & 38)
CAUTION:
• When using the kerf block, always cut at the same
miter angle.
• When changing the miter angle, use other kerf blocks.
• When performing bevel cuts, never use the kerf blocks.
Failure to do so splits the block, causing a serious injury
to operator.
When you use the kerf block at 90° cutting, you can splin-
ter-free cut in workpiece on the side of the guide fence
(height of the workpiece is up to 35 mm). Install the kerf
block onto the guide fence by means of the two screws.
(Adjust the guide fence and the kerf block so that they
contact their faces. Then tighten the screws securely.)

OPERATION

CAUTION:
• Before use, be sure to release the handle from the low-
ered position by pulling the stopper pin.
• Make sure the blade is not contacting the workpiece,
etc. before the switch is turned on.
• Do not apply excessive pressure on the handle when
cutting. Too much force may result in overload of the
motor and/or decreased cutting efficiency. Push down
handle with only as much force as is necessary for
smooth cutting and without significant decrease in
blade speed.

• Gently press down the handle to perform the cut. If the
handle is pressed down with force or if lateral force is
applied, the blade will vibrate and leave a mark (saw
mark) in the workpiece and the precision of the cut will
be impaired.
• During a slide cut, gently push the carriage toward the
guide fence without stopping. If the carriage movement
is stopped during the cut, a mark will be left in the work-
piece and the precision of the cut will be impaired.
1. Press cutting (cutting small workpieces)
(Fig. 39)
Workpieces up to 115 mm high and 75 mm wide can be
cut in the following way.
Push the carriage toward the guide fence fully and
tighten the knob clockwise to secure the carriage. Secure
the workpiece with the vise. Switch on the tool without
the blade making any contact and wait until the blade
attains full speed before lowering. Then gently lower the
handle to the fully lowered position to cut the workpiece.
When the cut is completed, switch off the tool and WAIT
UNTIL THE BLADE HAS COME TO A COMPLETE
STOP before returning the blade to its fully elevated posi-
tion.
CAUTION:
• Firmly tighten the knob clockwise so that the carriage
will not move during operation. Insufficient tightening
may cause unexpected kickback of the blade. Possible
serious PERSONAL INJURY may result.
2. Slide (push) cutting (cutting wide workpieces)
(Fig. 40)
Loosen the knob counterclockwise so that the carriage
can slide freely. Secure the workpiece with the vise. Pull
the carriage toward you fully. Switch on the tool without
the blade making any contact and wait until the blade
attains full speed. Press down the handle and PUSH
THE CARRIAGE TOWARD THE GUIDE FENCE AND
THROUGH THE WORKPIECE. When the cut is com-
pleted, switch off the tool and WAIT UNTIL THE BLADE
HAS COME TO A COMPLETE STOP before returning
the blade to its fully elevated position.
CAUTION:
• Whenever performing the slide cut, FIRST PULL THE
CARRIAGE TOWARD YOU FULLY and press down the
handle to the fully lowered position, then PUSH THE
CARRIAGE TOWARD THE GUIDE FENCE. NEVER
START THE CUT WITH THE CARRIAGE NOT FULLY
PULLED TOWARD YOU. If you perform the slide cut
without pulling the carriage fully or if you perform the
slide cut toward your direction, the blade may kickback
unexpectedly with the potential to cause serious PER-
SONAL INJURY.
• Never perform the slide cut with the handle locked in
the lowered position by pressing the stopper pin.
• Never loosen the knob which secures the carriage
while the blade is rotating. This may cause serious
injury.
3. Mitre cutting
Refer to the previously covered "Adjusting the miter
angle".
4. Bevel cut (Fig. 41)
Loosen the lever and tilt the saw blade to set the bevel
angle (Refer to the previously covered "Adjusting the
bevel angle"). Be sure to retighten the lever firmly to
secure the selected bevel angle safely. Secure the work-
piece with a vise. Make sure the carriage is pulled all the
