Operation - Makita LH1040 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 workpiece,
etc. before the switch is turned on.
CUTTING AS MITER SAW
WARNING:
• When using the tool in the miter saw mode, secure the
top table at the topmost position so that the saw blade
never protrudes from the top surface of the top table.
CAUTION:
• 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. 39)
Secure the workpiece against guide fence and turn
table. 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. 40)
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 against guide fence and turn
table. 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.
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.
Bevel angle
45°
006366
When performing compound cutting, refer to "Press
cutting", "Miter cutting" and "Bevel cut" explanations.
5. Cutting aluminum extrusion (Fig. 41)
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.
CAUTION:
• Never attempt to cut thick or round aluminum
extrusions. Thick aluminum extrusions may come
loose during operation and round aluminum extrusions
cannot be secured firmly with this tool.
• Never cut aluminum in the table saw mode (bench
mode).
6. Wood facing
Use of wood facing helps to assure splinter-free cuts
in workpieces. Attach a wood facing to the guide
fence using the holes in the guide fence.
See the figure concerning the dimensions for a
suggested wood facing. (Fig. 42)
CAUTION:
• Use straight wood of even thickness as the wood
facing.
• Use screws to attach the wood facing to the guide
fence. The screws should be installed so that the screw
heads are below the surface of the wood facing.
• When the wood facing is attached, do not turn the turn
base with the handle lowered. The blade and/or the
wood facing will be damaged.
7. Cutting repetitive lengths (Fig. 43)
When cutting several pieces of stock to the same
length, ranging from 240 mm to 400 mm, use of the
set plate will facilitate more efficient operation. Install
the set plate on the holder as shown in the figure.
Align the cutting line on your workpiece with either
the left or right side of the groove in the kerf board,
and while holding the workpiece from moving, move
the set plate flush against the end of the workpiece.
Then secure the set plate with the screw. When the
set plate is not used, loosen the screw and turn the
set plate out of the way.
