1.0 INTRODUCTION
The CPO 350-NF 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, combined with the self centering vise feature, gives a finished cut that does not
require any secondary machining or de-burring.
The high spindle speeds of this saw make it ideal for extrusions with varying cross section thicknesses.
To achieve the best results from this machine, use a good quality coolant and clamp the material
properly.
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.
The self centering vise allows for easy changeover to special clamping jaws for profiles and extrusions.
By adding the power vise and power down feed options, the saw can be converted to a semi-automatic
machine at a very reasonable price.

in accordance with the National Electric Code.
7. Disconnect the machine from the power source before performing maintenance or changing
blades.
8. Practice good housekeeping. Keep the area around the machine clean and dry.
9. When sawing, always support long pieces and make sure that the material is properly clamped.
10. Keep the guard, as well as all other parts of the saw, in good working condition. Replace worn
parts promptly.
11. Do not alter or modify this machine in any way without written permission from the
manufacturer.

4.2 MACHINE MOVING PROCEDURES
SEE FIGURE 2 BELOW.
FIGURE 2

Page 11
This machine is shipped on a pallet and can be moved to the installation location by means of a fork lift.
CAUTION: THIS MACHINE IS TOP HEAVY AND MUST BE MOVED WITH CARE, ON
HARD FLAT SURFACES ONLY.
All saws, except models equipped with the power down feed option, are shipped with the head locked in
the DOWN position.
Before lifting the machine, release the head by cutting the banding strap and allow it to move to the
UP position. Lift the machine using the lifting eyelet provided.
SEE FIGURE 2 ON THE PRECEDING PAGE.
Remove the pallet and place the machine in its final location.
This machine is top heavy and must be anchored to the floor.
4.3 PHYSICAL INSPECTION
Once the machine is located, check it for any possible damage incurred in shipment.
Remove the lifting eyelet and install the draw handle.
CAUTION: DO NOT USE THE LIFTING EYELET FOR ANY MACHINES OTHER THAN
THIS SAW.
After the draw handle has been installed on manual and power vise machines, remove the cover from the
electrical control box and connect the trigger switch wires.
REFER TO FIGURE 3A ON THE FOLLOWING PAGE.
Remove any other packing material and draw the saw head to its DOWN position, to make sure that the
guard opens properly.
The guard should close completely when the head is up and open freely as the head travels down.
If the guard is not functioning properly, REFER TO SECTION 4.6, for adjustment instructions.
Install the thirty (30) inch (76 cm) material length stop. The length stop mounts on the right side of the
vise base.
If your saw is equipped with either the power vise or the power down feed option, REFER TO
SECTIONS 7.1 AND 7.2, for additional information.

CAUTION: TO PREVENT DAMAGE TO THE MACHINE AND DANGER TO THE
OPERATOR, ALL ELECTRICAL CONNECTIONS SHOULD BE MADE BY A QUALIFIED
ELECTRICIAN. THIS MACHINE OPERATES WITH LIQUID COOLANT AND MUST BE
GROUNDED IN ACCORDANCE WITH NATIONAL ELECTRIC CODES.
All machines are wired for three phase power. The motors are single voltage, 230 or 460, and will
operate on one voltage only.
To insure satisfactory performance, the supply voltage should be (+ or -) 10% of the motor voltage
rating.
Check the motor data tag for full load current requirements.
THE ELECTRICAL DIAGRAMS FOR THIS MACHINE ARE ON PAGES 12-13, FIGURES 3A & 3B.
For supply lines ten feet (303 cm) or shorter, we recommend 12 gauge wire. For lines longer than ten feet
(303 cm), we recommend 10 gauge wire. We do not recommend supply lines over twenty feet (606 cm) in
length.

4.5 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.
On machines equipped with either a power vise or a power down feed, the air supply must also be
disconnected and locked or tagged. Scotchman offers a lock-out switch for this machine as an option, if
your plant is not equipped with lock-out capabilities. If you are interested in this option, REFER TO
SECTION 7.6 or contact your local dealer or the factory.
Do not install a blade on the saw until after it has been powered and cycled several times. TO POWER
MANUAL AND POWER VISE MACHINES, turn the power switch to the ON position and use the
trigger switch mounted in the draw handle to start the motor.
TO POWER MACHINES EQUIPPED WITH THE POWER DOWN FEED OPTION, turn the power
switch ON. Once the contactor has been energized, it will remain energized until the machine is
disconnected from the power source or until the emergency stop switch is depressed.
We do not recommend using the emergency stop switch to turn the machine off during normal operation.
If the emergency stop switch is used, it must be reset by manually pulling the switch back out. Always
turn the power switch to the OFF position when the saw is not in use.
Once the machine has been powered, check the rotation of the spindle. There is an arrow on the guard
showing the proper rotation. If the rotation is not correct, the electrician will have to switch two of the
three line wires.
If the saw is equipped with either the power vise or the power down feed options, SEE SECTIONS 7.1 &
7.2C, for additional information on electrical and air connections.

4.6 GUARD ADJUSTMENT-MANUAL MACHINES
Page 16
SEE FIGURE 4 ON THE FOLLOWING PAGE.
FOR GUARD ADJUSTMENT PROCEDURES ON SAWS EQUIPPED WITH THE POWER
DOWN FEED OPTION, REFER TO SECTION 7.2.
The proper adjustment of the blade guard on this machine is crucial to the operation of the
machine and the safety of the operator.
If the guard will not maintain proper adjustment, check the guard mounting bolts and rivet
joints in the guard and linkage for wear. Replace worn parts promptly.
USE THE FOLLOWING STEPS TO ADJUST THE BLADE GUARD:
1. Turn the power off and disconnect from the power source.
2. With the head in the UP position, loosen the mounting bolts (A) on the linkage mount (B).
3. Manually hold the guard open approximately 1/8 of an inch (3mm) at point (C).
4. Adjust the linkage mount (B) down until there is tension on the linkage bar. Re-tighten the
linkage mount bolts (A).
5. Manually cycle the head up and down several times, making sure that the guard operates
properly.
4.7 COOLANT SYSTEM
SEE FIGURE 5 ON THE FOLLOWING PAGE.
We recommend using only our P/N 075760, SYNCON-2 coolant in this saw. The NF coolant
reservoir has a capacity of (5) quarts (4.7 liters). One gallon of coolant is shipped with the saw.
For the best results, we recommend that it is used straight and not diluted. For additional
information on available coolants and lubes, SEE SECTION 10.6.

5.0 MAINTENANCE AND LUBRICATION
5.1 LUBRICATION
SEE FIGURE 6 ON THE FOLLOWING PAGE.
Before operating the saw, grease the pivot pin (A) and the spindle shaft (D) with a high pressure, high
temperature bearing grease.
Apply penetrating oil to the vise spindle and guides (B and C).
Once a week, grease all of the pivot pins and oil all of the rivet connections on the guard linkage.
Grease the spindle shaft (D) every eight hours of operation.
Clean the chips out of the vise at least once a day and more often, if needed. Apply penetrating oil to
the spindle and guide pins.
Clear the chips with a brush, vacuum or similar device. DO NOT use compressed air.
If your saw is equipped with a power vise or power down feed option, SEE SECTIONS 7.1 AND 7.2, for
additional information.
