General Instructions
Thank you for purchasing this quality machine from INVICTA.
As with all equipment, safety is to be the priority. The operator should understand the safety features as well as
apply good safety habits in transportation, adjustment, maintenance and operation of the machine. Practice and
teach others the safe operating procedures of this machine and help to prevent the possibility of accidents.
Safety Rules
1. For your own safety, read carefully the Instruction Manual before attempting to operate the machine.
2. If you are not thoroughly familiar and comfortable with the adjustment and operation of the machine, ask for
instruction from your supervisor or a fully qualified person. You may also contact Invicta USA.
3. Before the initial operation of the machine, remove all packaging, shipping grease and fully assemble the
machine. Pay special attention to the assembly of safety components.
4. Wear proper apparel while operating the machine. Never wear loose fitting clothing, gloves or ties. Always
remove rings or other jewelry before operating the machine. It is strongly suggested the operator wear
shoes with non-slip soles and also wear a protective hair net to prevent hair entanglement in moving parts.
5. Always wear personal safety equipment. Follow the safety regulations of your country and your company.
6. Have a certified person make all wiring connections to power source and properly ground the machine.
7. Always disconnect the machine from the power source and use lockout procedures before servicing,
changing cutting tools and during cleaning of the machine.
8. Before starting the machine, have the work area clean and free of debris. Cluttered areas are invitations for
accidents to occur.
9. Keep all safety guard(s) of the machine in place and in proper working condition. Never operate machinery
without safety equipment in place. Report any damage to your supervisor.
10. Keep children and visitors a safe distance from the working area.
11. Never leave the machine running while unattended. Turn off the power source during breaks. Before
walking away, allow the machine to come to a complete stop.
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.
Loading and Unloading
During loading and unloading, the machine should not be lifted by
components which could become damaged and affect it’s functioning.
The correct procedure is shown in figure 1.
NOTE: To remove the upper cover “A”, use the eye bolt “B” Figure 1. Do
not transport the machine through any point other than the eye bolts.
After this, reassemble and cover all the non painted surfaces with a
good quality paste wax.

Fastening the Machine to the Floor
To prevent vibration, set the machine correctly on the floor. The spacing
of concrete anchors is shown in figure 2 sketch.
Electrical Connection
The machine name plate supplies the specifications of the motor and
voltage requirements. Check the name plate for the voltage
requirements and cycles (Hz) before connecting the electrical power.
After completing the connection of the power lines, switch the machine
on and off quickly to see if the rotation of the wheel is clockwise while
standing at the operator’s position. If not, reverse any two of three
phases of power line, without changing the internal wiring of the
machine.
NOTE: If the machine has manual star delta starter, turn it to the start
position (star) and as soon as the motor reaches its maximum speed,
change over to the run position. Never do any work with the switch at
the start position.
Lubrication
Your machine requires periodic lubrication as follows:
1. Remove the guard “G” (Page 05). Lubricate the screw “H” with standard grease.
2. The threaded adjustment tee “43” should be lubricated with the same standard grease used for the screw.
3. The top wheel supporting slide “J” (Page 05) should be lubricated with standard grease.

1. To adjust the cutting height, loosen knob “P” (Page 06), then move the guide up to the desired height and
tighten knob again.
2. The screw “S” and “T” (Page 06) are used to adjust the blade guide for blade width and fine tracking.
3. To adjust the top blade guide bearings “Q”, loosen the locking screw “V” (Page 06) with a 3mm Allen
wrench. Adjustment is made by turning the eccentric shafts which the bearings are mounted using a 6mm
Allen wrench. For the axial adjustment “Q”, pull the shafts forward till you met the blade and lock screw.
4. To adjust the lower blade guide, loosen screws “X” (Page 06) with a 3mm Allen wrench until the bearing
lightly touches the saw blade. Then retighten.
NOTE: The guide pins “Y” should center the saw blade. If it is necessary, center the pins to the desired position
and fasten the lock screws again.

Adjusting the Belts
The belt tension adjustment is changed by bolt “N” and nut “O”, as shown in figure page 06. Do not over tighten or
premature belt wear will occur. Use just enough tension so that the belt does not slip under heavy cutting.
Adjusting the Table
Your machine is equipped with a fixed stop at 90º. To readjust this setting, loosen nut “L” and turn bolt “M” (Page
06) to the desired position. Relock nut “L” correctly.
Adjusting the Table Tilt
The work table will tilt up to 45º to the right. To adjust this feature, proceed as follows: loosen nut “K”, tilt the table
to the desired position and retighten (Page 05)
Adjusting the Rip Fence
Loosen the adjustable handle “E” and move the rip fence “D” (Page 05) in the desired direction to achieve the
proper cutting dimension. Lock in position using handle “E”.
Installing the Saw Blade
1. Turn the blade tension adjusting knob “I” (Page 05), and lower the top blade wheel.
NOTE: Safety guard “R” must be removed to install the saw blade (Page 06). Replace the safety guard when blade
is in place.
2. Tensioning the saw blade “F” (Page 05) is achieved by turning knob “I” to the correct setting.
NOTE: Correct blade tensioning is necessary for the blade to remain on the wheels when cutting. Release the saw
blade tension if the machine will not be used for an extended period of time. This will increase the blade life.
3. Perfect alignment of the saw blade on the rubber covered wheel is reached by turning screw “C” (Page 05) with
the 8mm Allen wrench. Blades should normally track center of the wheel.
Replacement Parts
Every INVICTA machine has a serial number which enables the manufacturer to identify the exact type and date of
its manufacture. At the end of this manual you will find a list of parts which compose your machine with their names
and numbers. Use only genuine INVICTA parts and on your order always mention the serial number, part number
and quantity desired.
