INTRODUCTION
Your new CIR-O is ready for operation when you receive it. A few minutes
spent reading the following will help you become familiar with the operation
and capabilities of your machine.
The CIR-O Carriage (C) should operate freely on the Ring Track (D). The
carriage has three adjustable Wheel Logs (A). By loosening the Flat Socket
Head Screws (B) these logs may be rotated for adjustment. To check Wheel
(AA) adjustment, hold one wheel and move the carriage. When properly
adjusted the wheel should barely slip.
The Cam Clutch (E) engages the drive pinion to the Ring Gear (F) by chang-
ing the position of the Drive Module (I). The Thumb Nut (H) locks the Cam
Clutch (E) in position.
Turning the Potentiometer Knob (K) regulates speed. The Switch (J)
controls forward-o-reverse. Throw the switch in the direction you want the
carriage to travel.
The CIR-O is furnished with four symmetrically-located Legs (L). A variety
of Magnetic Feet and legs (S), (T), (U), and (V) are available to increase
the versatility of the CIR-O machine.

POWER SUPPLY
The DC III drive operates on 120 volt, (42VAC), (240VAC), 50/60 Hz. The Circuit
Breaker (O) protects the unit against overload or electrical faults,
CAUTION: IF THE CIRCUIT BREAKER OPENS, FIND AND CORRECT THE
CAUSE OF FAILURE BEFORE RESETTING.
TORCH
The Torchholder (P) will accept any standard American machine torch (barrel
diameter 1-3/8" (34 mm) with 1/4"-square (6 mm) 32-pitch rack). The 32-pitch
pinion is standard. Specify a 24-pitch pinion if desired. The Short Hose As-
sembly (Q) connects the torch to the Quick-acting Manifold Assembly (R).
The supply hoses are to be connected to the open side of the quick-acting
manifold assembly.
Proper torch operation is essential to quality cuts. We suggest that you follow
the torch manufacturers’ instructions carefully, being sure to use a clean tip of
the proper size.
MAGNETIC SUPPORTS
Several Types of magnetic supports are available for use with the CIR-O to
stabilize the machine as listed below:
(S) Outrigger Support Assemblies; CON-1010 - used in multiples of two
or four to stabilize CIR-O on plate, cylinders or heads where two legs must
be longer than the other two,
(T) Magnet Foot Assemblies; CIR-9000 - may be used in sets of four or
more to position CIR-O on vertical or out-of-position, at surfaces.
(U) Leg and Magnet Foot Assemblies; CON-1040 (four required) - may be
used for at or irregular surfaces.
(V) Oset Leg and Magnet Assemblies; CIR-9002 (four required) - use with
a bevel cutting head or adjustable tip adaptor - to eliminate the “blind” spot
under the ring.
SETUP
A center-punch mark and a radius mark are the only layout required. The Center
Pin Assembly (Z) extends below the CIR-O base and is placed in the center-
punch mark. The CIR-O is then eased down to the work on the center pin. This
movement locates the entire machine “on center.” The Rack (W) with Torch-
holder (P) is then positioned over the radius mark.
OPERATION
In order to provide a smooth start, it is recommended that the starting hole be
drilled or pierced inside or outside the radius mark. Center the torch tip over the
radius mark and secure the Rack Stop (X) rmly against the Post Assembly
(Y). [The side of the post assembly to which the rack stop is positioned depends
upon whether the material inside or outside the cut is scrap]. Begin the cut from
the starting hole and, after carriage travel is begun, move the Torch Rack (W)
slowly against the Rack Stop (X). This action “feathers-in” the cut eliminating
a notch.

The purpose of the TEMPLATE KIT is to permit cutting of elliptical and
obround holes. The manner of accomplishing this job involves dragging the
torch barrel against a template which is made 11/16" (18 mm) larger on the
radius than the cut-out desired (when using standard US machine torches).
The TEMPLATE KIT consists of a master layout template (aluminum sheet),
which is used to locate the bolt holes and center on the actual template which
should be made from 1/8" (3 mm) masonite or similar material.
A full-size drawing of the shape to be cut, should be made showing a center
point, then add 11/16" (18 mm) to the radius. (Because the torch body drags
against the template, adding one-half the diameter of the torch to the drawing
will put the center of the torch tip in the right position.)
MAKING THE TEMPLATE
Lay the aluminum master layout template on the masonite board. Transfer
the holes from the master by tracing with a pencil or use a quick-drying spray
paint. Next, position the oversized drawing, so that the center point is directly
over the center on the template and the shape is located symmetrically be-
tween the ‘leg holes’ (see sketch Page 17, number 8. Trace [or spray] the
outline onto the template.)
Next, drill the holes in the template. Then, cut-out the outside circle (outside
of the template) and the shape to be cut (on the inside).
MOUNTING THE TEMPLATE
The four CIR-9031 spacer legs should be screwed into the ring gear. (Remove
existing 2" (50 mm) legs.) The template is then placed on these legs and the
2" (50 mm) legs, or 5" (127 mm) legs, when using the recommended CON-
1040 leg and foot assemblies) are screwed - through the template - into the
CIR-9031 spacer legs, which clamp the template under and parallel to the
ring gear. Insert four round head screws (see sketch Page 17, number 12)
through the template - into the alignment bars (see sketch Page 17, number 7.)
SET UP
Place the rod [see sketch Page 17 number 5 in the base post on the carriage.
Slip the tensioning assembly (see sketch Page 17, number 6) on the rod.
Install machine torch in torchholder - make sure torch is straight up-and-down
in both planes. Adjust tensioning assembly so that torch maintains rm contact
with template when carriage is rotated. Connect hoses. Place machine on
work - locate feet and lock in position.
STARTING THE CUT
Lock tensioning assembly so that the torch tip is over scrap area, piece - or
start the cut in starting hole. When preheat is complete start motor (carriage
travel), release tensioning assembly and let it gradually swing to template -
(this action ‘feathers’ the start into the cut.)

lter, oiler wick, a cover gasket and separator felt for the oiler lter.
LUBRICATION OF ARV-2020 AND ARV-2030 VACUUM PUMP KITS:
Fill jar to line indicated on “oil level decal” to avoid wetting felt, which would
increase oil feed. Use SOCONY DTE LIGHT OIL OR EQUIVALENT PETRO-
LEUM BASE OIL WITHOUT DETERGENTS. One lling should last 20-50
hours of operation. For slower feed, pull wick downward so that less wick is
exposed to air stream. Using the same oil as above, oil the motor bearings

The purpose of the TEMPLATE KIT is to permit cutting of elliptical and
obround holes. The manner of accomplishing this job involves dragging the
torch barrel against a template which is made 11/16" (18 mm) larger on the
radius than the cut-out desired (when using standard US machine torches).
The TEMPLATE KIT consists of a master layout template (aluminum sheet),
which is used to locate the bolt holes and center on the actual template which
should be made from 1/8" (3 mm) masonite or similar material.
A full-size drawing of the shape to be cut, should be made showing a center
point, then add 11/16" (18 mm) to the radius. (Because the torch body drags
against the template, adding one-half the diameter of the torch to the drawing
will put the center of the torch tip in the right position.)
MAKING THE TEMPLATE
Lay the aluminum master layout template on the masonite board. Transfer
the holes from the master by tracing with a pencil or use a quick-drying spray
paint. Next, position the oversized drawing, so that the center point is directly
over the center on the template and the shape is located symmetrically be-
tween the ‘leg holes’ (see sketch Page 17, number 8. Trace [or spray] the
outline onto the template.)
Next, drill the holes in the template. Then, cut-out the outside circle (outside
of the template) and the shape to be cut (on the inside).
MOUNTING THE TEMPLATE
The four CIR-9031 spacer legs should be screwed into the ring gear. (Remove
existing 2" (50 mm) legs.) The template is then placed on these legs and the
2" (50 mm) legs, or 5" (127 mm) legs, when using the recommended CON-
1040 leg and foot assemblies) are screwed - through the template - into the
CIR-9031 spacer legs, which clamp the template under and parallel to the
ring gear. Insert four round head screws (see sketch Page 17, number 12)
through the template - into the alignment bars (see sketch Page 17, number 7.)
SET UP
Place the rod [see sketch Page 17 number 5 in the base post on the carriage.
Slip the tensioning assembly (see sketch Page 17, number 6) on the rod.
Install machine torch in torchholder - make sure torch is straight up-and-down
in both planes. Adjust tensioning assembly so that torch maintains rm contact
with template when carriage is rotated. Connect hoses. Place machine on
work - locate feet and lock in position.
STARTING THE CUT
Lock tensioning assembly so that the torch tip is over scrap area, piece - or
start the cut in starting hole. When preheat is complete start motor (carriage
travel), release tensioning assembly and let it gradually swing to template -
(this action ‘feathers’ the start into the cut.)

DRIVE UNIT OPERATION
Rotating Cam Knob (B) will move the drive pinion in and out of engagement
with the ring gear.
To lock drive into position, tighten the 1/4-28 Wing Nut (A).
To disengage the drive pinion from the ring gear, loosen the 1/4-28 Wing
Nut (A) and turn Knob (B) counterclockwise. Turn Knob (B) clockwise to
engage the drive pinion with the ring gear, re-tighten the 1/4-28 Wing Nut
(A) to lock in position.
When Power Cord (C) is plugged into the appropriate power source, Pilot
Light (D) will glow. Switch (E) controls the direction of travel, with the cen-
ter position set at “OFF”. Knob (F) controls the speed. Circuit Breaker (G)
protects the unit against overload or electrical faults.
CAUTION: IF THE CIRCUIT BREAKER OPENS, FIND AND CORRECT
THE CAUSE OF FAILURE BEFORE RESETTING.

POWER SUPPLY
The DC III drive operates on 120 volt, (42VAC), (240VAC), 50/60 Hz. The Circuit
Breaker (O) protects the unit against overload or electrical faults,
CAUTION: IF THE CIRCUIT BREAKER OPENS, FIND AND CORRECT THE
CAUSE OF FAILURE BEFORE RESETTING.
TORCH
The Torchholder (P) will accept any standard American machine torch (barrel
diameter 1-3/8" (34 mm) with 1/4"-square (6 mm) 32-pitch rack). The 32-pitch
pinion is standard. Specify a 24-pitch pinion if desired. The Short Hose As-
sembly (Q) connects the torch to the Quick-acting Manifold Assembly (R).
The supply hoses are to be connected to the open side of the quick-acting
manifold assembly.
Proper torch operation is essential to quality cuts. We suggest that you follow
the torch manufacturers’ instructions carefully, being sure to use a clean tip of
the proper size.
MAGNETIC SUPPORTS
Several Types of magnetic supports are available for use with the CIR-O to
stabilize the machine as listed below:
(S) Outrigger Support Assemblies; CON-1010 - used in multiples of two
or four to stabilize CIR-O on plate, cylinders or heads where two legs must
be longer than the other two,
(T) Magnet Foot Assemblies; CIR-9000 - may be used in sets of four or
more to position CIR-O on vertical or out-of-position, at surfaces.
(U) Leg and Magnet Foot Assemblies; CON-1040 (four required) - may be
used for at or irregular surfaces.
(V) Oset Leg and Magnet Assemblies; CIR-9002 (four required) - use with
a bevel cutting head or adjustable tip adaptor - to eliminate the “blind” spot
under the ring.
SETUP
A center-punch mark and a radius mark are the only layout required. The Center
Pin Assembly (Z) extends below the CIR-O base and is placed in the center-
punch mark. The CIR-O is then eased down to the work on the center pin. This
movement locates the entire machine “on center.” The Rack (W) with Torch-
holder (P) is then positioned over the radius mark.
OPERATION
In order to provide a smooth start, it is recommended that the starting hole be
drilled or pierced inside or outside the radius mark. Center the torch tip over the
radius mark and secure the Rack Stop (X) rmly against the Post Assembly
(Y). [The side of the post assembly to which the rack stop is positioned depends
upon whether the material inside or outside the cut is scrap]. Begin the cut from
the starting hole and, after carriage travel is begun, move the Torch Rack (W)
slowly against the Rack Stop (X). This action “feathers-in” the cut eliminating
a notch.

INTRODUCTION
Your new CIR-O is ready for operation when you receive it. A few minutes
spent reading the following will help you become familiar with the operation
and capabilities of your machine.
The CIR-O Carriage (C) should operate freely on the Ring Track (D). The
carriage has three adjustable Wheel Logs (A). By loosening the Flat Socket
Head Screws (B) these logs may be rotated for adjustment. To check Wheel
(AA) adjustment, hold one wheel and move the carriage. When properly
adjusted the wheel should barely slip.
The Cam Clutch (E) engages the drive pinion to the Ring Gear (F) by chang-
ing the position of the Drive Module (I). The Thumb Nut (H) locks the Cam
Clutch (E) in position.
Turning the Potentiometer Knob (K) regulates speed. The Switch (J)
controls forward-o-reverse. Throw the switch in the direction you want the
carriage to travel.
The CIR-O is furnished with four symmetrically-located Legs (L). A variety
of Magnetic Feet and legs (S), (T), (U), and (V) are available to increase
the versatility of the CIR-O machine.
