Operation - Makita LS1040 Instruction Manual

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
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.
• Do not release the saw head uncontrolled from
the fully down position. Uncontrolled saw head
may hit you and it will result in personal injury.
Press cutting
► Fig.30
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.
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 posi-
tion 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 par-
allel 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.
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 cut-
ting can be performed at angle shown in the table.
Bevel angle
45
When performing compound cutting, refer to
"Press cutting", "Miter cutting" and "Bevel cut"
explanations.
Cutting aluminum extrusion
► Fig.32: 1. Vise 2. Spacer block 3. Guide fence
4. Aluminum extrusion 5. Spacer block
When securing aluminum extrusions, use spacer
blocks or pieces of scrap as shown in the figure to
prevent deformation of the aluminum. Use a cut-
ting lubricant when cutting the aluminum extrusion
to prevent build-up of the aluminum material on
the blade.
CAUTION:
• Never attempt to cut thick or round aluminum
extrusions. Thick aluminum extrusions may
come loose during operation and round alumi-
num extrusions cannot be secured firmly with
this tool.
