1.0 INTRODUCTION
Page 5
The CPO-315 RFA-NF Fully Automatic Cold Saw is a high speed saw designed to cut solids, tubes, flats
and other profiles in grades of nonferrous material that range from aluminum, brass, copper, synthetics
and extrusions.
Cold sawing is a process similar to a milling process.
In most cases, this gives a finished cut that does not require any secondary machining or de-burring.
The high spindle speed of this saw makes it ideal for extrusions with varying cross section thicknesses.
To achieve the best results from this machine, choose the proper spindle speed. Proper material
clamping and a good quality coolant are also important. We recommend our P/N 075760 coolant
(SYNCON-2) straight and not diluted.
Cold sawing has several advantages over band saws and abrasive saws.
Besides the mill quality cut, cold saws have the ability to generate faster cutoff times than band saws.
There are no sparks and excessive noises that are associated with abrasive cutoff saws.
There is also no work hardening of the material.
The vise allows for easy change over to special clamping jaws for profiles and extrusions.

4.2 MACHINE INSTALLATION
SEE FIGURE 2 ON THE FOLLOWING PAGE.
This machine is shipped on a pallet with the 60 inch discharge assembly attached to the saw. If the
optional 90 or 120 inch discharge assemblies are ordered, they are packaged separately and must be
assembled when they arrive. The material supply table is shipped disassembled.
⌦CAUTION: THIS MACHINE IS TOP HEAVY AND MUST BE MOVED WITH CARE, ON
HARD FLAT SURFACES ONLY.
USE THE FOLLOWING STEPS TO INSTALL THE MACHINE:
1. Select a location for the machine that allows adequate room for any length of material you may
want to cut. Leave adequate space behind the machine and on either end for set-up and
maintenance.
2. Lift the machine off of the shipping pallet, using a fork lift.
3. Place the machine in its final location and level it and the discharge track, using the leveling pads.
For this machine to function properly, it is very important that it is level.
4. Assemble the supply table following the instructions in SECTION 4.3 ON PAGE 12. Attach the
supply table to the machine and make sure that it is square to the machine and level with the

5.0 MACHINE START-UP
Before starting this machine, take the time to review the operator’s manual thoroughly, to familiarize
yourself with all of the functions of the machine.
We strongly urge you to follow OSHA directive CFR-1910.147 (effective 09-09-90) regarding lock-out,
tag-out procedures.
Keep in mind that the directive refers to all hazardous energy sources, not just electrical.
The air supply must also be disconnected and locked or tagged.
Do not install a blade on the saw until after it has been powered and cycled several times.
To power the motor, go to the manual operation screen and press the BLADE START button.
Once the machine has been powered, check the rotation of the spindle. On the guard, there is an arrow
showing the proper rotation. If the rotation is not correct, the electrician will have to switch two of the
three line wires.

Page 15
5.1 CONTROL PANEL FUNCTIONS
The following section gives a brief description of the touch screen and its functions. Before
powering the machine, please familiarize yourself with the location and the function of each of these
items. SECTION 7.0 will describe how to set the machine up for an operation.
SEE FIGURE 4 BELOW.
FIGURE 4

Page 16
5.1 A MAIN POWER SWITCH
This is the main power disconnect switch for the machine and it should be locked or tagged in the OFF
position any time maintenance or service work is being performed. Maintenance or service work on the
electrical controls must be performed by qualified personnel. This switch must be in the ON position
to operate any of the other control panel functions. The control panel will light up on the home screen
when the power switch (A) is on. With the hood switch open, cycle (D) stopped will appear on the
control panel screen. Scroll across the top of the screen, close the hood and push to continue. When the
E-Stop button (B) is pushed, the emergency stop will scroll across the top of the control panel screen.
Turn the E-Stop clockwise to re-set it.
⌦CAUTION: THIS SWITCH DOES NOT DISCONNECT THE AIR SUPPLY TO THE
MACHINE. ANY TIME MAINTENANCE OR SERVICE WORK IS PERFORMED ON THE
MACHINE, THE AIR SUPPLY MUST ALSO BE DISCONNECTED AND TAGGED OR
LOCKED OUT.

Page 17
5.1 B EMERGENCY STOP SWITCH
5.1 C FEED RATE CONTROL
5.1 D HOOD SAFETY SWITCH
This switch stops the saw motor and allows the head to return to the up position. The emergency
stop switch also applies the material vise air pressure. Once this switch has been used, the operator
must restart the machine. This is a maintained switch. Once it is depressed, you must manually
turn it clockwise to re-start the machine.
This valve controls the down feed rate of the saw head and is used in the set-up of the up and down
stroke control of the saw head. The down feed rate is determined by the material being cut. Small
sized material, thin wall tube, and some plastics can be cut quickly. Larger solid materials require
a slower feed rate. Always start with a slower feed rate and gradually increase it until the ideal
setting is determined.
Selecting the proper blade and the condition of the blade will affect the down feed rate
dramatically. Never use a dull blade!! It will need increased down force and take longer to cut and
will leave a poor finish on the cut and cause other problems.
This is the hood safety switch that turns the saw motor off when the hood is opened. Do not raise
the hood when the saw is making a cut. If you have to stop the saw in mid-cycle, press the head up
button if you are in the manual operation screen or the cycle stop button if you are in the
automatic screen or the emergency stop. DO NOT DISABLE THIS SWITCH!!

Page 18
5.1F CUT PROFILES
This is the CUT PROFILES MENU. Before performing any operation, you need to set up a cut profile
operation. The only profiles that come with the machine are the general or metric profile. You can store
up to 100 profiles. Press the recipe screen and name the profile. You can use any combination of
numbers or letters that you want for each particular profile.
Once you have named the profile, you need to set the parameters, starting with the FEED SPEED. This
setting is in inches per second and is the rate that the material feeds into the saw from the supply table.
For lighter materials, such as tubing, 25 is a good starting point. If your profile is heavier solid material,
start at 12.
The SAW SPEED is the RPM of the blade. The saw has an RPM range from 11 to 177. A good rule of
thumb here is the lighter material, the higher the RPM; the heavier the material, the lower the RPM.
TRIM LENGTH is the amount you want to trim off of the material before you start cutting actual parts.
The minimum trim length is ¾ inch.
The BRAKE POINT is the distance from the hard stop that the material feed starts to slow down. This
distance is also determined by the material that you are cutting. The heavier the material, the longer the
braking distance; the lighter the material, the shorter the distance.
FIGURE 6

Page 19
5.1G MANUAL OPERATION MENU
This is the MANUAL OPERATION MENU. The manual operation mode is used to calibrate the stop,
make sample cuts and set the stroke and other settings of the machine. All of the functions in the manual
menu will function when the saw hood is open, except the START blade function, the head up and
the head down buttons.
You have to have a profile selected in order to use the manual operation. The indicator lights on the
screen will tell you whether the vise is open or closed and what position the head is in.
The functions of this screen will be covered in each of the operations it is used for in more detail
throughout this manual.
