Compound Cutting - Makita LS1214 Instruction Manual

4. Bevel cut
Fig.44
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. Make
sure the carriage is pulled all the way back toward
the operator. 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 and PUSH THE CARRIAGE
TOWARD THE GUIDE FENCE 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.
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 down the handle, apply pressure 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 when
•
performing left bevel cuts.
5.

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.
Miter angle
Left and Right 45
Left 47
Right 52
006484
At the miter angle of left 45° and bevel angle of left
45°, workpieces up to 66 mm high and 170 mm
wide can be cut.
At the miter angle of right 45° and bevel angle of
left 45°, workpieces up to 66 mm high and 215 mm
wide can be cut.
At the miter angle of left and right 45° and bevel
angle of right 45°, workpieces up to 45 mm high
and 215 mm wide can be cut.
Bevel angle
Left and Right 0 - 45
Left 0 - 45 and Right 0 - 40
Left 0 - 30 and Right 0 - 45
When performing compound cutting, refer to
"Press cutting", "Slide cutting", "Miter cutting" and
"Bevel cut" explanations.
6. Cutting aluminum extrusion
Fig.45
Fig.46
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.
7. 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 and
6 mm screws.
See the figure concerning the dimensions for a
suggested wood facing.

CAUTION:
Use straight wood of even thickness as the wood
•
facing.
When cutting workpieces from 115 mm to 120 mm
•
high, use a wood facing to prevent a portion of the
workpiece near the guide fence from being left
uncut.
Example:
When cutting workpieces 120 mm high, use a
wood facing with the following thickness.

CAUTION:
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.
