Operation - Makita LS1040 Instruction Manual

CAUTION:
The workpiece must be secured firmly against
the turn base and guide fence with the vise dur-
ing all operations.
If some part contacts the vise, re-position the
vise arm. Press the workpiece flat against the
guide fence and the turn base. Position the work-
piece at the desired cutting position and secure it
firmly by tightening the clamp screw of the vise.
CAUTION:
When cutting long workpieces, use supports that
are as high as the top surface level of the turn
base. (Fig. 24)
2. Horizontal vise (optional accessory)
(Fig. 25 & 26)
The horizontal vise can be installed 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 table is to be turned. By turning the knob
on the vise counterclockwise, the screw is
released and the vise shaft can be moved rapidly
in and out. By turning the knob clockwise, the
screw remains secured. To grip workpieces, turn
the knob gently clockwise until the projection
reaches its topmost position, then fasten
securely. If the knob is forced in or pulled out
while being turned clockwise, the projection may
stop at an angle. In this case, turn the knob back
counterclockwise until the screw is released,
before turning again gently clockwise.
3. Holders and holder assembly(optional acces-
sories)
The holders and the holder assembly can be
installed on either side as a convenient means of
supporting workpieces horizontally. Install them
as shown in Fig. 27. Then tighten the screws
firmly to secure the holders and the holder
assembly. (Fig. 27)
When cutting long workpieces, use the holder-
rod assembly (optional accessory). It consists of
two holder assemblies and two rods 12. (Fig. 28)
CAUTION:
Always support long workpieces level with the
top surface of the turn base for accurate cuts and
to prevent dangerous loss of control of the tool.

Operation

CAUTION:
• Before use, be sure to release the handle from the
lowered position by pulling the stopper pin.
• Make sure the blade is not contacting the work-
piece, etc. before the switch is turned on.
• Do not apply excessive pressure on the handle
when cutting. Too much force may result in over-
load of the motor and/or decreased cutting effi-
ciency.
• 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.

When cutting with this tool, the thickness of the blade
is cut out of the workpiece as well. Therefore, your
cutting line should be on either the left or right side of
the groove in the kerf board. Switch on the tool and
wait until the blade attains full speed before lowering
gently into the cut. When the blade contacts the
workpiece, gradually bear down on the handle to per-
form the cut. 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 position. A thin piece of cut off
material could otherwise contact the coasting blade
and be thrown around dangerously. (Fig. 29)
1. Miter cutting
Refer to the previously covered "Positioning for
adjusting the miter angle".
2. Bevel cut (Fig. 30)
• Left 0° – 45° bevel cuts can be performed.
• Set the sub-fence to the left position as shown
in Fig. 17. Loosen the lever and tilt the saw
blade to set the bevel angle. Be sure to
retighten the lever firmly to secure the selected
bevel angle safely. Secure the workpiece with
the vise. Switch on the tool and wait until the
blade attains full speed. Then gently lower the
handle to the fully lowered position while apply-
ing pressure in parallel with the blade. 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 position.
CAUTION:
• When performing the bevel cut with the work-
piece secured on the left side of the turn base,
it will create a condition where the piece cut off
will come to rest on the blade. If the blade is
raised while the blade is still rotating, this piece
may be caught in the blade, causing fragments
to be scattered around which is dangerous.
The blade should be gently raised only after
the blade has come to a complete stop.
• When pressing down the handle, apply pres-
sure in parallel with the blade. If a force is
applied perpendicularly to the turn base or if
the pressure direction is changed during a cut,
the precision of the cut will be impaired.
• Always set the sub-fence to the left position as
shown in Fig. 17 when performing bevel cuts.
3. Compound cutting
Compound cutting can be performed at angle
shown in the table below.
Bevel angle
45°
When performing the compound cutting, refer to
"Miter cutting" and "Bevel cut" explanations.
