Operation - Makita LS1040 Instruction Manual

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.25
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.26
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
•
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.
1. Press cutting
Fig.27
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
position.
2. Miter cutting
Refer to the previously covered "Adjusting the
miter angle".
3. Bevel cut
Fig.28
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.
4. Compound cutting
Compound cutting is the process in which a bevel
angle is made at the same time in which a miter
angle is being cut on a workpiece. Compound
cutting can be performed at angle shown in the
table.

When performing compound cutting, refer to
"Press cutting", "Miter cutting" and "Bevel cut"
explanations.
5. Cutting aluminum extrusion
Fig.29
When securing aluminum extrusions, use spacer
blocks or pieces of scrap as shown in the figure to
prevent deformation of the aluminum. Use a
cutting lubricant when cutting the aluminum
extrusion to prevent build-up of the aluminum
material on the blade.
