unless damaged in shipping, should not require setting during
assembly. After extensive use, it may need to be checked. Make
adjustments only if necessary.
1. Unplug the saw.
2. Raise the blade to the maximum height by turning the high
adjusting handle clockwise.
3. Using a square (37), set the blade to exactly 90°. (Fig. 6-2)
4. If the blade stops bevelling before it gets to 90°, loosen the 90°
stop screw (38) (located in the left of the table insert) (Fig. 6-1)
with the 5 mm hex key (supplied), and then adjust it to 90°.
5. With the blade set at 90°, slowly turn the 90°-stop set screw until
you feel resistance. Bevel the blade away from 90° a little, and
then back to the stop.
6. Re-measure the angle, and repeat the stop adjustment as
necessary until the blade stops at 90°.

OPERATION
For safety reasons, verify that the operator has read the section
entitled general safety guidelines for the table saw before operating
this saw. Verify the following before every time the table saw
is used:
• The blade is tight.
• The blade bevel lock knob is locked.
• If ripping, the rip fence locking knob is tight, and the fence
is parallel to the miter gauge groove and the blade.
• If crosscutting, the miter gauge knob is tight.
• The blade guard and splitter are in place, and are working properly.
• Safety glasses are worn.
• Failure to adhere to these safety rules will greatly increase the
chances of injury.
Before using the table saw, polish the tabletop with an automotive
polishing wax in order to keep it clean, and to make it easier to slide
the workpiece.
There are two basic types of table saw cuts: ripping and crosscutting.
Ripping refers to cutting along the length of the grain and the work
piece. Crosscutting refers to either cutting across the width or across
the grain of the work piece. This distinction may be hard to make
with man made materials. Therefore, cutting a piece of material
to a different width is ripping, and cutting across the short dimension
is crosscutting.
Neither operation can be performed safely freehand: ripping requires
the use of the rip fence, and crosscutting requires the use of the
miter gauge. Never use the rip fence and the miter gauge at the
same time during the cutting operation.
ON/OFF SWITCH (Fig. 18)
Switching On
To start the operation, press the green I-push button (62).
Switching Off
Press the red O-push button (63) to stop the saw.
OVERLOAD PROTECTION (Fig. 19)
This saw is equipped with a reset overload relay button. It is situated
at the immediate right of the ON/OFF switch.
The reset button will restart the motor after it shuts off due
to overloading or low voltage.
If the motor stops during operation, press the red O-push button (63)
to make sure the switch is OFF. Wait approximately five minutes
for the motor to cool down and push the reset button. Now you can
switch to the ON position again.
WARNING: In order to avoid injury and prevent accidental start-up
when the reset button is pushed, the switch should be in the off
position, and the power cord should be unplugged from the outlet
while the saw is cooling down. Overheating may be caused by an
under-sized extension cord, an extension cord that is too long,
misaligned parts, or a dull blade. inspect the saw for proper set-up
before using it again.
