CRIMPING/GAGING PROCEDURE
1. Be sure the adapters match and that they are the same size
as the tubing. (1" tubing requires no adapters)
2. Place copper ring over end of tubing.
3. Push pipe onto barbed fitting all the way to shoulder stop.
4. Open the jaws and position the copper crimp ring so it is
centered within the tool jaws.
5. Before squeezing the handles make sure the copper crimp
ring is approx. 1 /8" to 1/4" from end of tubing and stop
shoulder on barbed fitting.
6. Squeeze the handles closed until the handle stops butt.
CRIMP EACH COPPER CRIMP RING ONCE ONLY!
7. Check the crimp with the crimp gage provided. Measure the
crimped ring perpendicular to the seams of the crimp as
shown in Figure 1. A properly crimped ring should pass the
GO side of the gage and not pass the NO-GO gage. If the ring
does not pass the GO gage the tool is probably worn and
needs to be adjusted as instructed in the Adjustment
Procedure.

ADJUSTMENT PROCEDURE
This tool is adjusted at the factory and no further adjustment should be necessary.
Should the tool, through extended use, require adjustment to compensate for wear
in parts, use the following procedure.
Adjustment Procedure:
1. Close tool handles until pre-load is reached (this is the point at which the jaws butt)
2. Measure the distance between the dots on the handle ends. 8" to 8 3/4" is the
correct distance for proper tool function.
3. To increase the distance, remove the #6-32 eccentric lock screw and push up
eccentric from back to disengage. Rotate counter-clockwise to increase the
distance and clockwise to decrease the distance. Push down eccentric and re-
install the #6-32 lock screw in the appropriate hole which most closely yields t he
desired handle distance..
4. Recheck the set distance after making three crimps.
5. Check the crimps with the Go/No-Go gauge provided. If crimps do not pass testing,
the tool is likely worn and should be replaced.
Maintenance Procedure:
1. Check tool calibration at least daily. It is recommended that the tool be checked
before the first crimp and after the last crimp of the day.
2. Never exceed the specified handle distance when adjusting your tool. Premature
wear will result.
3. Lubricate linkages on a regular basis to maximize tool life.
