then swinging it down between the two cutter bars (FIG. 5).
If necessary, loosen the adjustment knob further to widen
the space between cutter bars.
You are now ready to set the proper clearance for a clean
shear cut. Visually verify that the cutter is hanging between
the open cutter bars. Now, hold the cutter inward with your
finger (FIG. 6) and simultaneously turn the adjusting knob
clockwise until a light squeeze is felt between the cutter
bars and the cutter. DO NOT OVER TIGHTEN! You have
now set the correct clearance for your cut.
Raise the handle up fully and position your ring over the
cutter bars (FIG. 7 & FIG. 8). Now lower the handle to bring
the cutter in proper contact with the ring. After verifying that
the cutter is correctly positioned over the ring (FIG. 9), pull
smoothly downward on the handle until it stops. Your cut is
complete. Raise the handle, remove the ring. BE SURE TO
REMOVE THE RING SLUG from between the cutter bars.
Once you are familiar with cutter selection and adjustment,
you will find it to be a fast and simple process. The ring size
cutter has specially shaped cutters that conform to most
convex ring shanks. Notice that the actual cutting area is a
concave notch. This notch must be positioned properly over
the ring shank to make a clean cut. Fig. 9 shows both the
incorrect and correct cutter positions. Although these figures
are somewhat exaggerated, they illustrate an important
point.
INCORRECT CUTTER POSITIONS CAN PRODUCE
ROUGH CUTS AND DAMAGE THE CUTTERS
THEMSELVES!
If you follow the correct procedure for adjusting the cutter
clearance (FIG. 4 to FIG. 9), you will have little trouble with
this problem. Please be sure that the cutter is correctly
aligned before you pull the handle to cut.
MAINTENANCE
There is very little maintenance required for the ring size
cutter. With proper care, the cutters will provide good
service. This tool is designed to CUT PRECIOUS METAL
ALLOYS ONLY, such as used in jewelry. Do NOT use it
on hard steels, stainless steels, etc. The cutter and cutter
bars are replaceable. You will find the complete parts listing
on the back of these instructions. Cutters may be ordered
individually or in sets.
The cutter crank may need lubricant from time to time. Most
oils or grease will work. You may find small amounts of
metal building up on the cutters and inside the cutter bars.
This build -up can hamper correct cutter clearance since
it keeps the cutter bars further apart. If this happens, just
remove this built-up metal with a small file, but be careful
not to round the cutting edges. You should NEVER attempt
to cut anything that does not fit across BOTH cutter bars.
This tool is designed to cut a notch from a ring or part that
is supported on both sides. It is NOT a one side shear;
using it this way could cause damage.

TIPS: AVOIDING FRUSTRATION
AND RING DAMAGE
The GRS Ring Cutter cuts by shearing. Some ring shank
shapes and softer alloys may be distorted by this cutting
process. Here are some ways to minimize or prevent this:
1. Observe how the ring shank fits the curved area of
the cutter. Some shanks don’t fit the cutter curve well
enough. In a short time you’ll know which rings may
cause problems just by looking at them. You may decide
not to cut some rings with the Ring Cutter. Most jewelers
report using the GRS Ring Cutter well over 80% of
the time. Many tell us they use it virtually 100% once
