Operation; Miter Cutting - Makita LS1040 Instruction Manual

Position the vise arm according to the thickness and
shape of the workpiece and secure the vise arm by
tightening the screw. If the screw to secure the vise arm
contacts the guide fence, install the screw on the oppo-
site side of vise arm. Make sure that no part of the tool
contacts the vise when lowering the handle all the way.
If some part contacts the vise, re-position the vise.
Press the workpiece flat against the guide fence and the
turn base. Position the workpiece at the desired cutting
position and secure it firmly by tightening the vise knob.
CAUTION:
• The workpiece must be secured firmly against
the turn base and guide fence with the vise
during all operations.
Horizontal vise (optional accessory)
► Fig.27: 1. Vise knob 2. Projection 3. Vise shaft
4. Base
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 oppo-
site the direction in which the turn base is to be turned.
By turning the vise knob counterclockwise, the screw
is released and the vise shaft can be moved rapidly in
and out. By turning the vise knob clockwise, the screw
remains secured. To grip the workpiece, turn the vise
knob gently clockwise until the projection reaches its
topmost position, then fasten securely. If the vise knob
is forced in or pulled out while being turned clockwise,
the projection may stop at an angle. In this case, turn
the vise knob back counterclockwise until the screw is
released, before turning again gently clockwise.
The maximum width of the workpiece which can be
secured by the horizontal vise is 130 mm.
CAUTION:
• Grip the workpiece only when the projection is
at the topmost position. Failure to do so may
result in insufficient securing of the workpiece.
This could cause the workpiece to be thrown,
cause damage to the blade or cause the loss
of control, which can result in PERSONAL
INJURY.
Holders and holder assembly
(optional accessories)
► Fig.28: 1. Holder 2. Holder assembly
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 the
figure. Then tighten the screws firmly to secure the
holders and the holder assembly.
When cutting long workpieces, use the holder-rod
assembly (optional accessory). It consists of two holder
assemblies and two rods 12.
► Fig.29: 1. Holder assembly 2. Rod 12
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 cut-
ting. 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.
Press cutting
► Fig.30
Secure the workpiece with the vise. Switch on the tool with-
out 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 position.

Miter cutting

Refer to the previously covered "Adjusting the miter angle".
Bevel cut
► Fig.31
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 workpiece with a vise. Switch
on the tool without the blade making any contact and wait until
the blade attains full speed. Then gently lower the handle to
the fully lowered position while applying 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:
• Always be sure that the blade will move down to
bevel direction during a bevel cut. Keep hands
out of path of saw blade.
• During a bevel cut, it may create a condition
whereby the piece cut off will come to rest against
the side of the blade. If the blade is raised while
the blade is still rotating, this piece may be caught
by the blade, causing fragments to be scattered
which is dangerous. The blade should be raised
ONLY after the blade has come to a complete stop.
• When pressing the handle down, apply pressure
parallel to the blade. If the pressure is not parallel to
the blade during a cut, the angle of the blade might be
shifted and the precision of the cut will be impaired.
• Always set the sub-fence to the left position
when performing left bevel cuts.
