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-0 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 changing the position of the Drive Module (1). The Thumb Nut (H) locks the Cam
Clutch (E) in position.
Turning the Potentiometer Knob (K) regulates speed. The Switch (J) controls
forward-off-reverse. Throw the switch in the direction you want the carriage to
travel.
The CIR-0 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-0 machine.

OPERATING INSTRUCTIONS (CON’T.)
POWER SUPPLY
The DC III drive operates on 120 volt, (42VAC), (240VAC), 50/60 Hz. The
Circuit Breaker (0) 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 Assembly (0) 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-0 to
stabilize the machine as listed below:
(S) Outrigger Support Assemblies; CON-1010 - used in multiples of
two or four to stabilize CIR-0 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-0 on vertical or out-of-position, flat surfaces.
(U) Leg and Magnet Foot Assemblies; CON-1040 (four required) - may be
used for flat or irregular surfaces.
(V) Offset 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.
SET UP
A center-punch mark and a radius mark are the only layout required. The
Center Pin Assembly (Z) extends below the CIR-0 base and is placed in the
center-punch mark. The CIR-0 is then eased down to the work on the center
pin. This movement locates the entire machine “on center.” The Rack (W)
with Torchholder (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) firmly against the Post As-
sembly (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.

BUG-5100-F DC III DRIVE UNIT
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 center
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.
