12. Do not operate the machine under the influence of drugs or alcohol. Consult your physician when taking
medications.

13. Do not force the machine beyond its limitations. It will produce a nicer and safer job at the rate it was
designed to operate.

Additional Safety Rules for the Operation of Table Saws

1) Avoid Kickbacks. “Kickback” can occur when the workpiece is forced back by the saw blade during improper
operation. When “Kickback” occurs injury can result. Some causes of Kickback are:
A- Dull blades or an improperly adjusted fence in relation to the blade.

B- Knots, Nails or Imperfections in the workpiece.

C- Heavier cutting than the machine was designed for.

D- Failure to use a pusher block when cutting thin or narrow workpieces.

2) Never start the work-piece into the blade before allowing it to reach full operation speed.

3) Use the correct tooth style and rake for the material you plan to cut.

4) Keep the Blade sharp and free of rust and pitch

5) Use good safety habits when using dado blades.

6) Support and control the workpiece properly all times during the operation.

7) Never reverse the direction of the workpiece after beginning operation. Kickback can occur.

8) Definitions of ripping, crosscutting and dadoing of the workpiece:
A- Ripping operations: Cutting the material in the same direct as the flow of the grain.
B- Crosscutting operations: Cutting the material across the grain. This may produce heavy splintering.
C- Dado operations: Cutting a flat-wide bottom grove in the material.

Loading and Unloading

Fig.01

Never load or unload the machine by any component that could be
damaged. Transporting the machine by the directions in Fig.01 is the
recommended procedure.

After placement has been completed, remove all the protective grease
or varnish from the machined surfaces using kerosene or a similar
solvent.

Installing the machine

On a solid surface, level the machine (Fig.02) then add all
attachments such as the blade guard and fences.

Connecting Electricity

Each machine is provided with a reference plate that
indicates the requirements for electrical service needed
for the machine to operate property. Before you call a
certified electrician to make the wiring connections, be
sure that the voltage and cycle (phase) stated on this
reference plate are the same as provided in your building.

(Electrician) Remove the electrical box cover and connect
the electrical supply wires to the proper terminals. Rapidly
turn on and off the machine and then visibly check the
rotation direction of the saw blade. It should rotate so as
the top of the exposed blade travels toward the operator’s
position while sawing. See page 7
For changing blade direction for three-phase machines:
invert two wires of the power source without changing the internal connections of the machine. Should further
information be needed please contact Invicta USA.

IMPORTANT:

If your machine is equipped with a star-triangle switch (Y∆), first turn it to the start position and when the motor
reaches its maximum speed turn it immediately to the triangle position. Never operate the machine with the swich
in the start position or damage may occur.

Controls

1. ELECTRIC SWITCH (pag. 07)

2. SAW TILT ADJUSTMENT HANDWHEEL (pag. 07)

This handwheel is used to adjust the tilt angle of the saw from 0º to 45º. To adjust this feature, loosen lock knob nº
4 then turn the handwheel nº 2 until the desired angle is obtained, relock. The angle is read on scale nº 5

3. SAW BLADE HEIGHT ADJUSTING HANDWHEEL (pag. 07)

This handwheel is used to adjust the amount of blade that protrudes through the top of the material. Before moving
the handwheel, loosen lock knob nº 6, then relock after the adjustment is completed.

Rip Fence Alignment

The relationship between the rip fence and the blade assembly has been aligned from the factory. Should the fence
require adjustment due to shipment, please follow the procedure below.
First loosen or tighten nuts nº 11 as needed until the desired parallel relationship is obtained between the saw
blade and the rip fence. Never adjust the rip fence so that the distance between the blade and fence on the output
end is less than on the input end. This slightly greater distance at the output side of the blade will decrease the

possibility of pinching or binding of the material.

Rip Fence Width Adjustment

Proceed as follows: First loosen lock lever nº 7 and turn knob nº 8 until the desired adjustment is obtained. Relock
by lever nº 7. The width of the cut is read on scale nº 9. To obtain the longitudinal adjustment of the guide it is
necessary to loosen the two knobs nº 10, retightening after adjustment.

Scale Pointer Adjustment (page 07)

The scale pointer may need occasional adjustment due to variations in saw blade kerfs. When adjustment is
necessary, proceed as follows: First, disconnect power supply then slide the rip fence gently against the saw blade.
Loosen knob nº 13 and adjust the pointer to zero on scale nº 9 to zero. Complete the adjustment by locking nº 13.

Adjustment of the tilt limit stops (page 07)

These stops are designed to give the blade an exact locator for 0º and 45º. These stops have been adjusted at the
factory. If later adjustment is necessary: place a precision square against the blade and adjust to 0º, loosen nut nº
14, and adjust acrew nº 15 until the blade stops at the correct position. Tighten nut nº 14. Follow the same
procedure for the 45º adjustment.

Vertical Saw Blade Adjustment (page 07)

Stops nº 16 limits the maximum and minimum height travel of the blade. These stops have been adjusted at the
factory. If future adjustment is necessary, loosen nuts nº 17 and adjust screw nº16 to increase or decrease the
blade travel. Once positioned, tighten nº 14 nuts. Do Not use a blade that is larger than specified.

Saw Guard Adjustment (page 07)

Saw guard/blade slitter adjustment is by handle nº 18. The saw guide/blade slitter support is adjusted by nuts nº19,
and should be readjusted according to the saw blade diameter each time the blade is changed.

Belt Tension Adjustment (page 08)

To adjust belt tension or change belts, loosen screw nº 20 and adjust as necessary. Tighten screws.

Procedure for Changing the Saw Blade (page 08)

Remove the saw guard by loosening the lock handle nº 18. Remove the table blade insert (item nº 21) and depress
the blade locking pin (item nº22). Loosen nut nº 23 with the special wrench supplied with the machine. Change to
the desired blade. Keep all collars clean and free from burrs. Reassemble all components. (Note spindle has LH
thread.)

Table Insert Adjustment (page 07)

The table insert is adjusted at the factory for perfect flush alignment with the top of the table. Should future
adjustment be needed, make adjustments by screws nº 24.

Miter Fence (page 08)

The miter gauge is designed to control the angle of the wood material as it is sawn. The angle is adjusted as
follows: Loosen locking handle nº 25 and turn the guide to the desired angle and retighten the locking handle. The
cutting angle can be read on scale nº 26.

Electrical Protection equipment (page 09)

The machine can be optionally supplied with electrical overload protection. This equipment disconnects the motor
automatically when there is an electrical overload that could damage it. When the motor is disconnected, it is
necessary to reset the therrmal relay by pressing the reset button (point nº 02). Continue by pressing the start
button. On pages 9 thru 12 are electrical diagrams for special motorization.

Instructions for replacing the Sawdust Guard

Your machine is equipped with a wooden guard (ballast) that helps to prevent sawdust from being blown up
through the table insert. This is a very important feature when dust collection is absent or very poor. Due to normal
wear it becomes necessary to change this guard, proceed as follows: Raise the saw blade to its maximum height,
remove the table insert. Replace the wooden guard with a new one of the same dimensions. Next, mount the new
piece of wood in the guard, and reassemble table insert. Turn the saw on and slowly lower it to its minimum height,
executing the cut in the wood. (Always lockout the power supply when doing blade maintenance)
