PRACTICAL APPLICATIONS

WARNING
* To avoid personal injury, never remove or place a
workpiece on the table while the tool is being
operated.
* Never place your limbs inside of the line next to
warning sign while the tool is being operated. This
may cause hazardous conditions (see Fig. 26).
Line Warning sign
1. Switch operation
Pull the trigger to turn on the switch, release it to shut
it off.
After releasing the trigger, make sure the trigger has
gone all the way back and the switch is turned off.
2. Using the Vise Assembly (Standard accessory)
(1) The vise assembly can be mounted on either the left
fence {Fence (B)} or the right fence {Fence (A)} by
loosening the 6 mm wing bolt (A).
(2) The screw holder can be raised or lowered according
to the height of the workpiece by loosening the 6 mm
wing bolt (B). After the adjustment, firmly tighten the
6 mm wing bolt (B) and fix the screw holder.
(3) Turn the upper knob and securely fix the workpiece
in position. (Fig. 28)

WARNING
Always firmly clamp or vise to secure the workpiece
to the fence; otherwise the workpiece might be thrust
from the table and cause bodily harm.
CAUTION
Always confirm that the motor head (see Fig. 1) does
not contact the vise assembly when it is lowered for
cutting. If there is any danger that it may do so, loosen
the 6 mm wing bolt (B) and move the vise assembly
to a position where it will not contact the saw blade.
3. Cutting operation
(1) As shown in Fig. 29 the width of the saw blade is the
width of the cut. Therefore, slide the workpiece to the
right (viewed from the operator's position) when length
is desired, or to the left when length
If a laser marker is used, align the laser line with the
left side of the saw blade, and then align the ink line
with the laser line.
(2) Once the saw blade reaches maximum speed, push
the handle down carefully until the saw blade
approaches the workpiece.
(3) Once the saw blade contacts the workpiece, push the
handle down gradually to cut into the workpiece.
(4) After cutting the workpiece to the desired depth, turn
the power tool OFF and let the saw blade stop
completely before raising the handle from the
workpiece to return it to the full retract position.

CAUTION
Increased pressure on the handle will not increase the
cutting speed. On the contrary, too much pressure
may result in overload of the motor and/or decreased
cutting efficiency.
WARNING
* Confirm that the trigger switch is turned OFF and the
power plug has been removed from the receptacle
whenever the tool is not in use.
* Always turn the power off and let the saw blade stop
completely before raising the handle from the workpiece.
If the handle is raised while the saw blade is still rotating,
the cut-off piece may become jammed against the saw
blade causing fragments to scatter about dangerously.
* Every time one cutting of deep-cutting operation is
finished, turn the switch off, and check that the saw
blade has stopped. Then raise the handle, and return
it to the full retract position.
* Be absolutely sure to remove the cut material from the
top of the turntable, and then proceed to the next step.
