Installation and Set Up:
The CTD saw you have purchased is designed to cut wood, aluminum, plastic and steel, with, of course, the
proper blade and conditions. For the material you are cutting, please refer to the cutting instructions for each
material type. The 200R Series machines use a NEMA 56 Frame 2 H.P., 3450 RPM, 60 Hertz TEFC Motor.
CTD uses a speed-up so that the blade will run at approximately 11,000 SFPM on a 12” blade.
IMPORTANT: Before operating saw, please be sure to read the “SAFETY INSTRUCTIONS TO THE
OPERATOR” (see Page No. 7).
Note: The floor stand must be shimmed, leveled and bolted to the floor, or framed in to eliminate vibration.
Use holes provided in bottom of floor stand. All machines have been completely assembled at the factory,
then disassembled for shipment.
Assembly of Floor Stand, Support Tables and Measuring Gages:
Standard Machine—The standard model has been completely assembled. Fences are set at the centerline
of the blade (see Diagram “D” on Page No. 5). Adjust fences forward if necessary for your particular material.
The machine base must be level. The incoming material and outgoing material must lay flat on the machine
base (see Diagram “F” on Page No. 10).
Floor Stand Model—The 200R and 300R Series base is attached to the Floor Stand by means of three hex cap
screws bolted from the bottom of the base. The Floor Stand must be shimmed and leveled, and, if necessary,
bolted to the floor to eliminate vibration. The F255R is attached with (2) socket cap screws from the top in front,
and (1) hex cap screw from the bottom in the rear.

Assembly of Tables to Floor Stand:
1. Assemble leg to table with 3/8-16 bolts and nuts provided. Turn table upside down and attach leg to table
with leg rising vertically. Note: The hole in the table (when mounted properly) should be toward the back
of the table and at the far end from the blade to attach Fence Support Angle, P/N BF16 (see Diagram “A”).
2. Attach Table, P/N BF17 to machine floor stand on Angle Bracket, P/N BF05C. Use 3/8-16 bolts and
nuts provided on angle bracket.
Blade Installation:
Before setting blades on spindle, always shut off or disconnect air supply. With Motor OFF and Power
Disconnected, rotate Lower Blade Guard (p/n 200A270) up into Main Blade Guard (p/n 200A26L or R). Slide
link puller (p/n 200M320) off puller screw and bushing through large hole on slot. Remove four machine nuts on
Blade Guard Cover (200F250L or R). The entire Lower Blade Guard Cover Assembly (p/n 200E250L or R)
comes off as one piece, exposing spindle nut and flange. (Refer to Diagram “D” on Page No. 5.).
Attaching Extended Fence Gage:
1. Place Extended Fence Gage (5/8 x 2” material) on table. Bolt to fence bracket with screws provided.
Adjust fence gage so measurement rule is correctly set:
A. With a scale or ruler touching the side of the tips of the blade, measure a distance away from blade.
Be sure the ruler and the tape on the fence gage read the same. This may be visually deceiving. Use
a 90° square to check.
B. Adjust fence, left to right, as necessary.
C. Both fences, left and right, must be in perfect alignment. Use a long straight edge for this purpose
(see Diagram “D” & “E”).
D. Attach fence support angle to fence and table.

Blade Installation (continued):
1. Remove Spindle Nut, P/N 2B1P36 or 2B1P37 and Outer Flange, P/N 200BM03. If necessary, hold blade
in hand with rag or lower blade into a piece of wood, and loosen spindle nut by pushing down on a 15/16”
wrench.
2. Place blade on spindle with tips pointing down. Make sure Slinger (inner flange), P/N 200BM04, and
blade surface are clean before putting blade on spindle. This is a critical surface and is ground within
.0005 flatness. Any debris or dust will wear this surface. Wipe both surfaces (blade and slinger) with
a clean rag.
A. The blade must ALWAYS rotate to the rear of the machine on the underside of the blade
(see Diagram “D”). Always check rotation before cutting a piece of material.
3. Replace Outer Flange, P/N 200BM03 and nut as before and tighten (refer to Diagram “C”). Pull up with
15/16” wrench. Do not over-tighten. Snugging the blade is all that is necessary.
4. Replace Blade Guard Cover Assembly as before making sure Lower Blade Guard covers blade.
If blades were purchased from CTD, your machine has been set with your blades. If not, blade diameters may
vary. Check to see if the blade contacts the base or disc in the down position. If repositioning is necessary,
adjust down stop bolt located under Arm casting, P/N 200BC01L or R.
These machines are general purpose in
their design, therefore the user should
attach any additional guarding to the
blade guard or table base if the cutting
application causes unsafe blade exposure.
This label is attached to the blade guard.
Never put hand or fingers near or
under the moving blade.Use a piece
of wood to remove short pieces from saw.
Blade Guard:
The blade and belt drive are enclosed. When the saw arm is lowered, the lower blade guard rotates up into the
main blade guard. The blade continues through the work as the lower blade guard rotates up.
NEVER remove any blade guard part, exposing the blade.

Electrical Installation:
The CTD 200R Series Cut-Off Saws use 2 H.P. single or three phase 3450 RPM, 60 HZ TEFC (totally enclosed fan
cooled) motors on a NEMA 56Z Frame. CTD uses a speed up drive so that the blade will run at approximately 3700
RPM. The motor is turned “ON” and “OFF” using the manual overload starter located on the top of the motor.
Electrical installation should be performed by a qualified and certified electrician. It is highly recommended
that a lock-out or disconnect switch be located close to the machine between your main electrical panel and
the machine. This disconnect switch is used to shut off power to the machine and should be used whenever
the blades are changed, or at any time the machine is serviced and the blade is exposed. A manual overload starter has
been provided as a standard feature. The starter protects the motor from overheating and will not allow the motor to restart
itself after power outages or undervoltage situations. A Magnetic Starter is also available as an optional accessory.
Electrical Installation of Power to Starter by a Qualified Electrician:
All wiring from the motor to the starter has been completed and tested at the factory several times.
The voltage has been clearly tagged. DO NOT CONNECTANY VOLTAGE THATIS DIFFERENT THAN
THE TAGGED VOLTAGE, AS THIS MAY CAUSE SEVERE DAMAGE AND DANGER. Consult the factory
if any changes are needed.
Bring power lines to the top of the Manual Overload Starter or Magnetic Starter. Use dust proof connectors if available.
Single Phase Motors:
Connect leads to L1 (line 1) and L2 for single phase motors. (See Wiring Diagram for Single Phase Motors
below.) Green ground wire must be grounded to enclosure. If using type “SO” wire and plug, use a romex
connector through starter box and a grounded plug. Be sure to check rotation. The blade must rotate down
and to the rear on the underside of the blade (see Diagram “D” on Page No. 5). If a change in rotation is necessary, switch
the #8 and #5 wires in the electrical box on the motor. Rotation is set at factory for single phase motors.
Three Phase Motors:
Connect incoming power line leads to L1 (line 1), L2 and L3. (See Wiring Diagram for Three Phase Motors
below). Green ground wire must be grounded to enclosure. Be sure tocheck rotation as polarities may be
different. The blade must rotate down and to the rear on the underside of the blade (see Diagram “D” on
Page No. 5).
If a change in rotation is necessary, reverse any two of the incoming power wires. Example: Ifthe blades
are running backwards and incoming wires are connected White L1, Black L2, Red L3, switch the Black
wire with the Red so that Black is connected to L3 and Red is connected to L2. This will change the motor
to rotate properly.

Safety Instructions to the Operator:
1. KNOW YOUR CTD SAW. Read this instruction manual carefully. Learn the operation, application, and
limitations, as well as the specific potential hazards peculiar to this machine.
2. Avoid accidental starting. Make sure switch is OFF before plugging in power cord. A Magnetic Starter
is provided as an optional accessory to give the operator added protection. (OSHA required by user.)
3. Always use a plug equipped with a ground.
4. Always keep blade guard in place. Do not wire-up or chain-up, so that blade is exposed.
5. Be sure all unnecessary tools are removed from machine before turning on power.
6. Use safety goggles. Also use a face or dust mask if operation is dusty.
7. Support work. To maintain control of work at all times, it is necessary that material be level with
cutting surface.
8. Wear proper apparel. Do not wear loose clothing or jewelry. Do not wear a tie or gloves. These items
can get caught in the moving parts of the machine.
9. Do not over-reach. Keep your proper footing and balance at all time.
10. Maintain your machine in top condition. Use proper blades. Clean machine weekly for proper
maintenance.
11. Keep work area clean. Cluttered areas, benches and slippery floors invite accidents.
12. Avoid dangerous environments. Keep work area well illuminated.
13. Wear ear protection if exposed to long periods of very noisy shop operations.
14. Keep visitors away. All visitors should be kept a safe distance from work area.
15. Do not force the machine. The saw will do a better job and be safer to operate at the speed for which it
was designed. Forcing the saw can be very hazardous to the operator.
16. Use recommended accessories. Use of other accessories may be hazardous. Use this instruction manual
or consult CTD for the proper accessories available.
17. Do not drown the blade using a steady stream of coolant when cutting non-ferrous materials. Only spray
the work to cool it.
18. Be sure to use the proper blade for the particular material to be cut.
19. Disconnect power cord before adjusting, servicing, and before changing belts, or for installing
accessories.
20. Safety is a combination of operator COMMON SENSE and ALERTNESS at all times when the machine
is being used.
21. WARNING!!! DO NOT ALLOW FAMILIARITY (GAINED FROM FREQUENT USE OF YOUR
SAW) TO DULL YOUR AWARENESS!! ALWAYS REMEMBER THAT A CARELESS FRACTION OF
A SECOND IS SUFFICIENT TO INFLICT SEVERE INJURY!!

Wiring Diagrams

Positioning the Work:
Fences should be set so that the centerline of the work is either to the front, or on the centerline of the blade
(see Diagram “D”). Fences must be adjusted so that short pieces cannot be trapped between the blade and
the fences. The Fences are adjustable side to side to close the gap. Gap should be 1/16” to 1/8”. Fences must be in line
with each other—front to back (see Diagram “E”). If very short pieces are to be cut, a piece of wood or aluminum can be
fixed to the table to make a sub-table, which will stop pieces from being trapped between the blade and the saw slot
(see Diagram “G” on Page No. 10). New machines are provided with a Chip Breaker which eliminates the need for a
subtable.

Diagram “E”Diagram “D” Blade Rotation
1. Pull back spring loaded mitre locking pin & handle assembly & rotate to the right or left. This prevents the pin
from engaging. Mitre lock pin & handle will lock in the open position.
2. Make sure mitre lock down bolt (located in the center of the pivot bracket-see Diagram “D” & “E”) is loosened.
3. To lock in at preset angles, rotate sawhead and disc near the desired angle aligning with zero mark on base.

How to operate the 200R Series Single Cut-Off Saws:
Before operating the machine, please read the “SAFETY INSTRUCTIONS TO THE OPERATOR” above.
Other important information and features need to be learned before operating the machine.
Rotation:
The blade must rotate to the rear of the machine on the underside of the blades (see Diagram “D” below).
Blade Guard:
The blade and belt drive are enclosed. When the saw arm is lowered, the lower blade guard rotates up into
the main blade guard. The blade continues through the work as the lower blade guard rotates up. NEVER
remove any blade guard part, exposing the blade. These machines are general purpose in their design,
therefore the USER should attach additional guarding to the blade guard or table base if his cutting application
causes unsafe blade exposure.
