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 ﬁ tting until it is ﬂ ush with

the ﬁ tting shoulder. If unable to slide tubing over

the ﬁ tting, remove from ﬁ tting and expand one

additional time. Important! You should feel some

resistance as the ﬁ 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 ﬁ tting .

10.Tubing should ﬁ t tightly against the ﬁ 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) off the end of the tubing and restart

the procedure with a new ProPEX

Ring.

Cold-weather Use

Colder weather (<40°F/4°C) requires a longer con-

traction time and fewer expansions.

Troubleshooting ProPEX

Connections

If ﬁ ttings will not seal, check for the following:

• Is the expander head screwed on tightly? Tighten

the head securely. Ensure the head is tight against

the tool.

• Are the expander head segments bent or mis-

aligned? Replace expander head.

• Are the expander head segments failing to contract

between expansions? Clean the head and lubricate

the cone. Ensure cogs are engaged.

Cogs

•Is the expander cone over or under lubricated?

Clean and lubricate.

• Is the ﬁ tting damaged? Replace ﬁ tting.

• Is the expander cone bent or damaged? Return to

a MILWAUKEE service facility for repair.

• Was the expander head held in the expanded posi-

tion before tubing was removed? Cut 3"-5" (3" for 2"

PEX and 5" for 2.5" and 3" PEX) off the end of the

tubing and restart the procedure with a new ProPEX

Ring.

• Was the tubing rotated slightly after each expan-

sion? Cut 3"-5" (3" for 2" PEX and 5" for 2.5" and

3" PEX) off the end of the tubing and restart the

procedure with a new ProPEX

Ring.

• Are the tubing and ProPEX

Ring clean and dry?

Wipe dry.

• Is grease getting into the tubing from the expander

head? Wipe grease from tubing. Clean the expander

head, ensuring excessive amounts of grease are not

present on the head.

If ProPEX

Ring slides during expansion:

• Are the tubing and ProPEX

Ring clean and dry?

Wipe clean.

• Are your hands clean and dry? Wipe dry — oils from

your hands can lubricate the tubing and ProPEX

Ring.

• Are you holding the ring in place? Place your thumb

against the ring and hold in place during ﬁ rst couple

of expansions.

If expander head does not expand when trigger is

pulled:

• Verify that the expander head is fully retracted.

• Set tool on a work surface with the cone pointing up.

Pull the trigger and hold until the green light indicates

that the press cycle has started. Release the trigger

and then press and hold the manual retract button

until the motor stops (up to 1 minute). Repeat if

expander head still does not expand when trigger

is pulled.

If the head does not fully retract at the end of an

expansion:

• Press the manual release button to fully retract the

expander cone

• Remove the expander head from the tool and rein-

stall, verifying proper installation.

MAINTENANCE

WARNING

To reduce the risk of injury, always

unplug the charger and remove the

battery pack from the charger or tool before

performing any maintenance. Never disassemble

the tool, battery pack or charger. Contact a

MILWAUKEE service facility for ALL repairs.

Maintaining Tool

Keep your tool, battery pack and charger in good

repair by adopting a regular maintenance program.

Each month:

• Remove the expander head and

Lubrication

areas

soak in degreasing agent to

remove grease from between

expander segments. Re-lubri-

cate head (expander head

collar groove, expander cone

mating surface).

• Wipe expander cone and rotate

collar with clean, dry, lint-free

cloth. Re-lubricate when com-

plete.

4. Screw the head onto tool (clockwise). Hand tighten

securely. Do not over tighten. The expander head

must ﬁ t tightly against the tool.

5. Check installation:

a. Ensure the head segments

Flowering

segments

do not “ﬂ 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

ﬁ t ﬂ 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 speciﬁ 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.

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

Ring over

ring

1/16"

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.

After six months to one year, depending on use,

return the tool, battery pack and charger to A

MILWAUKEE service facility for:

• Lubrication

• Mechanical inspection and cleaning (gears, spin-

dles, bearings, housing, etc.)

• Electrical inspection (battery pack, charger, motor)

• Testing to assure proper mechanical and electrical

operation

If the tool does not start or operate at full power with

a fully charged battery pack, clean the contacts on

the battery pack. If the tool still does not work prop-

erly, return the tool, charger and battery pack, to a

MILWAUKEE service facility for repairs.

WARNING

To reduce the risk of personal in-

jury and damage, never immerse

your tool, battery pack or charger in liquid or

allow a liquid to ﬂ ow inside them.

Cleaning

Clean dust and debris from charger and tool vents.

Keep tool handles clean, dry and free of oil or grease.

Use only mild soap and a damp cloth to clean the

tool, battery pack and charger since certain cleaning

agents and solvents are harmful to plastics and other

insulated parts. Some of these include gasoline,

turpentine, lacquer thinner, paint thinner, chlorinated

cleaning solvents, ammonia and household deter-

gents containing ammonia. Never use ﬂ ammable or

combustible solvents around tools.

Repairs

For repairs, return the tool, battery pack and charger

to the nearest service center.
