The position of riving knife (Fig. 1) should be changed
as follows.
(1) Loosen the clamping nut and hold the lower
blade guard A using its lug by hand (Fig. 2).
(2) While holding the lower blade guard A, pull
the riving knife so that it turns and pivot it to
the position in the direction of arrow (Fig. 3).
(3) With the riving knife held in that position,
return the lower blade guard A to the original
position and tighten the clamping nut
securely (Fig. 4, 5).
OPERATION
CAUTION:
•
Before use, be sure to release the handle from the
lowered position by pulling the stopper pin and
turning it to the angle of 90°.
•
Make sure the blade is not contacting the
workpiece, etc. before the switch is turned on.
CUTTING AS MITER SAW
WARNING:
•
Make sure that the lower blade guard C is installed
before using in miter saw mode.
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.49
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.50
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.
•
Always remove the sub-fence 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.

Cutting aluminum extrusion
Fig.51
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.
