GENERAL POWER TOOL SAFETY WARNINGS

WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

• Keep work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks that may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodifi ed plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the infl uence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your fi nger on the switch or energizing power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of chil-dren and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc., in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

BATTERY TOOL USE AND CARE

• Recharge only with the charger specifi ed by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fi re when used with another battery pack.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fi re.
• When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fi re.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

SERVICE
Have your power tool serviced by a qualifi ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

SPECIFIC SAFETY RULES

• Use tool only to expand PEX-a material. Other materials may split or crack, causing leaking.
• Store tool with expander head installed to protect expander cone from damage.
• Keep fi ngers away from expander head during use. When expander head contracts, pinching can occur.
• Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.
• WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

CAUTION Use only MILWAUKEE M12™ ProPEX™ expander heads or Uponor Standard expander heads. The use of incorrectly sized expansion heads may result in faulty connections, which could result in property 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 MILWAUKEE Expander Cone Grease Cat.No. 49-08-2400 to the expander cone. Do not over-lubricate.

CAUTION Improper lubrication (too much or too little) may result in faulty connections, which could result in property damage.

• Do not expand tubing beyond the tool’s capac-ity (1″).
• Pull trigger and verify that the expander head is rotating after each cycle when using MILWAUKEE M12™ ProPEX™ expander heads.

1. Cut the PEX tubing to the needed length. Use only cutters designed for PEX tubing. Make sure the cut is perpendicular to the length of the tubing.

2. Slide the ProPEX™ Ring over the end of the tubing until it butts aginst the ring stop.
   If the ring does not have a stop, leave an over-hang of no more than 1/16″. When using 3/8″ ProPEX™, refer to “3/8″ ProPEX™ Rings” for proper assembly

3. Insert the expander head into the PEX tubing.

4. Pull the trigger. The expander head will expand, retract, and rotate slightly in each cycle.
   NOTE: When Uponor Standard expander heads are used, the head will NOT rotate automatically. Each time the segments contract, gently push the tubing up onto the expander head and rotate 1/8 turn in either direction.

CAUTION When using Uponor Standard expansion heads, properly rotate the tubing after each expansion to create even, smooth expansion marks. Not rotating the tubing may cause deep grooves and faulty connections, which could result in leaking and property damage.

• Fewer or more expansions may be necessary, as influenced by weather and technique.

  1. Continue until the tubing and ring are flush with the expander head shoulder.
  2. Remove the tubing when the segments are contracted and release the trigger. To avoid over-expanding the tubing, do not keep tool in the expanded position with tubing in place.
  3. Wipe excess grease from inside tubing.
  4. Slide the tubing over the fi tting until it is fl ush with the fi tting shoulder. Connection may be tight. If unable to slide tubing over the fi tting, remove from fitting and expand one additional time.
  5. Tubing should fi t tight against the fitting shoulder. If more than 1/16″ gap between tubing and shoulder, cut 2″ off the end of the tubing and restart procedure with a new ProPEX™ Ring.

3/8″ ProPEX™ Rings
The 3/8″ ProPEX™ Rings do not fi t over 3/8″ tubing without expanding the ring separately.

1. Place the ProPEX™ Ring on the expander head and pull the trigger to expand the ring once.

2. Remove the ring.

3. Flip the ring over

4. Place the ring on the expander head and pull the trigger to expand the ring once more.

5. Immediately remove the ring and slide onto the tubing.
   NOTE : The 3/8″ ProPEX™ Rings shrink faster than other size rings.

6. Continue with step 3 of “Making PEX Tubing Connections”.

Cold-weather Use
Colder weather (<40°F/4°C) requires a longer contraction time and fewer expansions. Do not make ProPEX™ connections in temperatures under 5°F (-15°C).

Troubleshooting ProPEX™ Connections
If fittings will not seal, check for the following:

• Is the expander head screwed on tightly? Tighten the head securely.

• Are the expander head segments bent or misaligned? Replace expander head.

• Are the expander head segments failing to contract between expansions? Clean and relu-bricate.

• Is the expander cone over or under-lubricated?Clean and relubricate.

• Is the fitting damaged? Replace fitting.

• Is the expander cone bent or damaged? Return to a MILWAUKEE service facility for repair.

• Was the expander head held in the expanded position before tubing was removed? Cut 2″ off tubing and restart process.

• Was the tubing rotated slightly after each expansion when using an Uponor Stanard expansion head? Cut 2″ off tubing and restart process.

• 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 and relubricate expander 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 first couple of expansions.

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 re-pair by adopting a regular maintenance program. Each month:

• Remove the expander head and soak in de-greasing agent to remove grease from between expander segments.

• Wipe expander cone with clean, dry, lint-free cloth. Re-lubricate.
