For use with:
‑ PEX-B pipe.
‑ Brass or poly alloy couplings.
1. Set the impact driver to reverse (couterclockwise) and
depress the trigger of the impact driver to fully open the
jaws
until an audible click is heard from the DWAPXCIR.

2. Slide a new crimp ring
insert the coupling
.

3. Position the crimp ring
from the end of the PEX tube and the coupling
fitting manufacturer's instructions, as shown in Fig. L.
nOTE: Before crimping, ensure the crimp ring
properly on the coupling
4. Secure PEX tubing to prevent it from moving while crimping.
5. Position the DWAPXCIR opening of the jaws
corresponds to the size of the crimp ring

8. Set the impact driver to reverse (couterclockwise) and
depress the trigger of the impact driver to allow for removal
from the crimp ring from the jaws

Using the Go/No-Go Gauge (Fig. M)
1. Remove the battery from the tool.
2. After each PEX crimp, the quality of the crimp should be
verified with the provided go/no-go gauge
3. Insert the pressed crimp ring
gauge
10
for the corresponding crimp ring diameter.
4. If the go/no-go gauge

18
, the tool will need to be adjusted by
reducing the numeric setting on the eccentric cam.
5. If the crimp ring
15
slides into the slot and stops on the
GO range shoulder
, the crimp is good.
19
6. If the ring slides all the way into the slot, then the the
crimp ring is compressed too small and is a "NO-GO". The
tool will need to by adjusted by increasing the numeric
setting on the eccentric dial
