CAUTION
Improper lubrication (too much or
too little) may result in faulty con-
nections, which could result in property damage.
• Do not expand tubing beyond the tool's capacity
(3" / DN75).
1. Cut the PEX tubing to the needed length. Use only
cutters designed for plastic tubing. Make sure the
cut is perpendicular to the length of the tubing.
2. Slide the ProPEX

tubing
the end of the tubing until it
butts aginst the ring stop.
3. With expander head NOT
inserted in the tubing, pull and
hold the trigger to initiate the
rotation of the expander head.
CAUTION
Do not force the tubing onto the
expander head.
4. When the green indicator light
turns on and/or the white work
light flashes, insert the ex-
pander head into the PEX
tubing and release the trigger.
5. The expander head will con-
tinue to expand. When the expander reaches
maximum diameter it will automatically retract.
NOTE: To cancel quickly, pull and release trigger.
6. Tool will be fully retracted when green indicator
light blinks 3 times. The next expansion can be
started.
7. Continue expanding until the tubing reaches the
shoulder of the expander head. Then expand 1 to
2 more times, depending on the room temperature
(the warmer the temperature, the more expansions
are necessary).
CAUTION
Ensure the expander head rotates
at the beginning of each stroke to
ensure creation of even, smooth expansion
marks. If the head is not rotating, the expander
head may cause deep grooves in the tubing and
faulty connections, which could result in a leak.

8. Remove tubing when the segments are contracted.
9. Slide the tubing over the tting until it is ush with
the tting shoulder. If unable to slide tubing over
the tting, remove from tting and expand one
additional time. Important! You should feel some
resistance as the tting goes into the tubing If you
do not feel any resistance, the tubing may be over
expanded and will require additional time to shrink
over the tting .
10.Tubing should t tightly against the tting shoul-
der. If more than 1/16" gap between tubing and
shoulder, cut 3"-5" (3" for 2" PEX and 5" for 2.5"
and 3" PEX) o󰀨 the end of the tubing and restart
the procedure with a new ProPEX

Ring.

assembly.
Changing Expander Heads
To remove an expander head:
1. Remove the battery pack.
2. Place the tool with the head pointing up and un-
screw the head (counterclockwise).
To install an expander head:
1. Remove the battery pack.
2. Place the tool with the head pointing up.
3. Verify that the expander cone is fully retracted.
4. Screw the head onto tool (clockwise). Hand tighten
securely. Do not over tighten. The expander head
must t tightly against the tool.
5. Check installation:
a. Ensure the head segments

segments
do not “ower”.
b. Rotate the six expander
segments in the clockwise
direction. The head will rotate
freely. The head should not
rotate counterclockwise.
c. The expander head collar will
t ush against the tool.
d. Correct installation by loos-
ening the head slightly and
rotating the segments until
they engage in the cogs. Re-tighten the head.

OPERATION
WARNING
Always remove battery pack before
changing or removing accesso-
ries. Only use accessories specically recom-
mended for this tool. Others may be hazardous.
To reduce the risk of injury, wear safety goggles
or glasses with side shields.
CAUTION
Use only MILWAUKEE M18™ Pro-
PEX
®
expander heads. The use of
incorrectly sized expansion heads may result in
faulty connections, which could result in prop-
erty damage.
Making PEX Tubing Connections
To ensure a proper connection:
• Remove the expander head and remove any dirt
and debris.
• Use a clean, lint-free cloth to apply a thin coat of
ProPEX
®
Expander Cone Grease to the expander
cone. Do not over or under-lubricate. Wipe excess
grease from inside collar and cone before expand-
ing tubing.
