3. Make a perpendicular cut to PEX tubing to the needed
length. Use OnlY cutters designed for PEX tubing.
4. Slide the PEX Ring 11 over the end of the PEX
tubing 12 until it sits properly against the ring stop. If
the PEX ring does not have a stop, leave an over-hang of
no more than 1/16" (1.6 mm) (Fig. G)

5. Insert the expander head into the PEX tubing (Fig. H).
6. Squeeze the trigger switch
begin to expand, retract, and rotate slightly.
nOTE: Hold the ring and tubing so they do not rotate with
the head.

nOTE: The number of expansions needed may vary
depending on temperature or user technique. To avoid over-
expanding the PEX tubing, do not keep tool in the expanded
position with PEX tubing in place.
7. After achieving the recommended number of expansions,
remove the tubing when the expander cone
are retracted and release the trigger switch
expand the PEX tubing beyond the tool's capacity of
1 inch.
8. Wipe off the excess grease from inside the PEX tubing.
9. Slide the PEX tubing over the fitting until it is flush with
the fitting shoulder. The connection may be tight. If you
are unable to slide the PEX tubing over the fitting, remove

the fitting from the PEX tubing and re-expand until you
can secure a proper fit.
nOTE: The PEX tubing should fit tightly against the fitting
shoulder. If there is more than a 1/16" (1.6 mm) gap between
the PEX tubing and the shoulder, cut 2" (50 mm) off the end
of the PEX tubing and restart procedure with a new PEX Ring.
Making 3/8" PEX Tubing Connections
(Fig. A, G)
The thicker 3/8" PEX rings will not fit over 3/8" PEX tubing
without first expanding each end of the PEX ring.
1. Insert the expander head
2. Squeeze the trigger switch
head to exapand the PEX ring once.
3. Remove the PEX ring and repeat steps 1 and 2 for the
other end of the PEX ring.
4. IMMEDIATELY slide the PEX ring onto the end of the PEX
tubing 12 leaving an over-hang of no more than 1/16"
(1.6 mm)(Fig. G).
nOTE: 3/8" PEX rings will shrink faster than other size
PEX rings.
5. Continue with the steps outlined in Creating a PEX
Tubing Connection to complete your connection.
Cold weather use
Use of your PEX expander in colder temperatures
(<40 °F/4 °C) requires a longer contraction time and less
expansions. Attempting to make PEX connections in
extreme temperatures (<5 °F/-15 °C) is not recommended.
Expansion Markings (Fig. I)

CAUTION: Incorrect expansion of the PEX tubing can
create deep grooves in the material which could result
in faulty connections and risk of property damage.
Examples of correct and incorrect markings on the inside of
the PEX tubing are shown in Fig. I. Incorrect markings could
indicate the head is not rotating properly, or the tubing is
rotating with the head.

MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can cause injury.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this.

WARNING: Never use solvents or other harsh
chemicals for cleaning the non-metallic parts of
