INFORMATION ON THESE PAGES. THIS
MANUAL CONTAINS IMPORTANT SAFETY AND
OPERATING INSTRUCTIONS. IT SHOULD BE
RETAINED WITH THE MACHINE FOR FUTURE
REFERENCE.
SAFETY PRECAUTIONS - MECHANICAL
!DO NOT OPERATE UNIT WITHOUT GUARDS IN
PLACE OR WITH DAMAGED GUARDS.
!DO NOT DEFEAT ANY OF THE SAFETY
FEATURES.
!DO NOT PLACE FINGERS OR APPENDAGES
NEAR MOVING PARTS OR IN OR NEAR

GROUNDING INSTRUCTIONS. Grounding provides
a common return path for electric current to reduce

conductor and a grounding plug. The plug must
be plugged into a matching outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.

Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
Check with a licensed electrician if in doubt as to
whether the machine is properly grounded.
SAFETY FIRST - USE BEST PRACTICES
ALWAYS USE SAFETY GLASSES. Everyday
eyeglasses only have impact resistant lenses; they
are NOT safety glasses. Also use face or dust mask
if cutting operation
is dusty.
REMOVE ADJUSTING KEYS AND WRENCHES.
Form a habit of checking to see that keys and
adjusting wrenches are removed from machine
before turning it on.
KEEP WORK AREA CLEAN. Cluttered areas and
benches invite accidents. Always leave at least 12”
(305 mm) of space around all sides and top of unit.
DON’T USE IN DANGEROUS ENVIRONMENTS.
Do not use or locate machine in high-humidity
environments, or expose to rain. Keep work areas
well lighted.
WEAR PROPER APPAREL. Do not wear
loose clothing, such as gloves, neckties, rings,
bracelets, necklaces or any other clothing or
jewelry that might get caught in moving parts. This
is not an all-inclusive list. Wear protective hair
covering to contain long hair. Non-slip footwear is
recommended.
DON’T OVERREACH. Maintain proper footing and
balance at all times.
MAINTAIN BLADES WITH CARE. Keep blades
sharp and clean for optimal performance. Follow
instructions for lubricating and changing blades and
all accessories.

accessories.
DO NOT EXCEED THE UNIT’S MAXIMUM
MATERIAL SPECIFICATIONS. Eraser’s warranty
will be null and void if machine has been used in any
manner that is contrary to these instructions.
CHECK FOR DAMAGED PARTS. Before continued
use of the machine, the guard and all moving parts
should be carefully inspected to ensure that nothing
is damaged.
Ensure proper alignment of moving parts. Check
for any binding of moving parts, breakage of parts,
and any other condition(s) that may a󰀨ect operation.
Any damaged part(s) should be properly repaired or
replaced prior to any continued use of the machine.
ONLY ALLOW TRAINED AND QUALIFIED
PERSONNEL TO OPERATE UNIT. Always keep
these instructions within reach of the machine.
USE RECOMMENDED ACCESSORIES ONLY.
Consult this operating manual for recommended
accessories. Use only parts supplied by The Eraser
Company, Inc. Use of improper accessories will void
Eraser’s warranty and may increase risk of injury.

OPERATING INSTRUCTIONS
SET-UP:

1/8”, one 5/32” & one 9/64” Allen wrench. Bushings
must be purchased separately.

!Caution: The rigid tubing cutting wheel head is
intended for rigid tubing. Thin wall soft steel is
the practical limit for the machine.
Place the Model RTC1 on a sturdy workbench with
the right corner of the exit opening even with the
right corner of the bench. Short and long cut lengths
will drop out the side of the exit bushing. Material
collection bins can be placed to collect the cut
material as it exits the unit.
BUSHING INSTALLATION:
To aid in bushing installation refer to the drawing.
If di󰀨erent sizes of material are going to be cut,
additional bushing sets must be ordered. There
are two guide bushings, the input and exit bushing.
Install the input bushing & gently tighten the set
screw with the 3/32 Allen wrench. Install the exit
bushing in the front cover with the two screws
provided. See pictures 1 & 2.
Feed the tubing in through the input bushing and out
through the exit bushing. Set the length stop block
to approximately provide the desired cut length.
While gently squeezing them together, tighten
the adjacent collars with the provided 7/64” Allen
wrench. The actual cut length may be rened after a
sample is cut. Longer cut lengths may be produced
by purchasing additional length stop rods (TR0176)
which may be screwed directly into the one provided
with the machine. See picture 1.
Connect the power cord to the IEC connector, and
plug the unit into the appropriate power supply
(either 120V 60Hz OR 230V 50Hz).
OPERATION:
Push the material through the input bushing, head,
& exit bushing until it reaches the length stop block.
See pictures 1 & 2.
Turn the machine on using the I/O switch on the top
of the unit. Set the speed control to approximately
75% as a starting point. Depress the footswitch to
cut the material. When the material is cut; release
the footswitch. The cut time will vary based the
material being cut. Cut times will range from a
fraction of a second to several seconds. Lower
machine speeds may cut better on lighter or softer
materials & higher speeds will be necessary for
thicker wall or harder materials. Rotate the length

stop block, remove cut piece & return block to
verticle position. See picture 2.
CUTTING WHEEL REPLACEMENT,
AND DEPTH ADJUSTMENT:
!CAUTION: BE SURE UNIT IS UNPLUGGED
BEFORE CHANGING CUTTING WHEELS.
To replace the cutting wheels rst remove the 2
screws near the top of the front cover with a 1/8”
Allen wrench. Lift o󰀨 the cover. Remove 2 roller
holder screws with the 5/32 Allen wrench. Remove
1 brass washer & the cutting wheel assembly from
the roller holder. Using (2) 1/2” wrenches loosen the
jam nut from the disk bushing & remove the cutting
wheel. Install the new cutting wheel & reverse the
disassembly procedure to reassemble. Repeat this
process for the other cutter wheel. See pictures 1,3
& 4.
To adjust the cutting wheels deeper, turn the depth
screws counterclockwise using the 5/32” Allen
wrench provided. The depth is properly set when the
cutting wheels are slightly deeper than the inside
wall of the tubing being cut. The depth screws must
be adjusted equally for the cutting head to function
properly. See pictures 3 & 4.
!CAUTION: BE CERTAIN THAT THE JAM NUT
SIDE OF THE CUTTER WHEEL ASSEMBLY
FACES THE ROLLER HOLDER. IF THE DISK
BUSHING SIDE FACES THE ROLLER HOLDER
THE CUTTER WILL NOT OPERATE.
MAINTENANCE:
!CAUTION: BE SURE TO UNPLUG THE UNIT
BEFORE PERFORMING ANY MAINTENANCE.
BE SURE TO EMPLOY APPROPRIATE ANTI-
STATIC PROCEDURES/DEVICES WHEN
DISASSEMBLING AND ASSEMBLING UNIT.
1) Check the cutting wheels for wear after
prolonged use. See pictures 3 & 4.
2) Belt tensioning or replacement begins with
removing 4 screws & the rear housing with a #2
Phillips screwdriver. Remove the 2 screws & the
front cover with a 1/8” Allen wrench. Loosen the
4 motor mounting screws using the 5/32 Allen
wrench. Slip the old belt o󰀨 the cutterhead pulley

p 5
Eraser Company Inc. • Syracuse, NY USA • Ph: 315-454-3237 • [e-mail] • www.eraser.com • Fax [phone]
& the motor pulley and replace with the new
one. Slide the motor to the right (away from the
cutter head) & hold in place while tightening the
4 mounting screws. Replace the rear housing &
front cover. Reapply power & start the machine.
If the belt slips on startup repeat the process but
apply more tension to the belt before tightening
the motor mounting screws. See picture 4 & 5.
3) A light spray lube should be applied sparingly
to the moving components on the rigid tubing
cutterhead. Care should be taken not to get any
lube on to the belt surface of the cutterhead
pulley. See pictures 3 & 4.
4) No other maintenance is required for the units.
