Frequently Asked Questions - 244120 MILWAUKEE

How to install a caulk cartridge in the gun?

Make sure the battery is removed and the switch is in the Release rack position. Cut the cartridge tip according to the manufacturer's recommendations, pierce the inner seal. Pull the rod handle back, insert the cartridge into the carrier, then push the rod until the piston touches the cartridge. Finally, set the switch to the Forward position.

How to use the variable speed function?

Use the speed selection dial (1 to 6) to adjust the flow rate. A slower speed (1) is recommended for small diameter tips, while a higher speed (6) is suitable for wider tips. Press the trigger to dispense material. The trigger pressure and the selected speed affect the flow rate.

What does the battery charge indicator mean?

When the tool is turned on, the fuel gauge lights up for 2-3 seconds. If less than 10% charge remains, a light flashes 4 times. At low charge, 8 flashes indicate the battery needs charging. If the battery is too hot, the lights flash and the tool will not work; let it cool down.

How to clean the Milwaukee glue gun?

Disconnect the battery. Use a damp cloth and mild soap to clean the tool. Avoid flammable solvents like gasoline or turpentine that can damage the plastic and insulation.

What types of cartridges can I use?

Use only standard caulk or adhesive cartridges and sausage packs suitable for the M12™ gun. Do not use damaged or frozen cartridges. Specific Milwaukee rods and carriers must be used to avoid damaging the tool.

What to do if the tool does not dispense caulk?

Check that the tip is cut, the inner seal is pierced, there is no hardened material in the tip, the cartridge is not damaged or frozen, and the rod is properly inserted. If the problem persists, the tool may be in overload; release the trigger and check conditions.

How to insert and remove the battery?

To remove the battery, press the release buttons and pull it out of the tool. To insert, slide it into the tool body until it snaps securely. Make sure it is firmly attached before use.

What is the warranty for the Milwaukee 244120 glue gun?

GENERAL POWER TOOL SAFETYWARNINGS

WARNING

Read all safety warnings, instructions, illustrations and specifica

tions provided with this power tool. Failure to follow all instructions listed below 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 (cored) 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 which 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. Unmodified 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 ground fault circuit interrupter (GFCI) protected supply. Use of an GFCI 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 influence 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 a 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 finger 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 jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry 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.
- Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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 remove the battery pack, if detachable, 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 children 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 and accessories. 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.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

BATTERY TOOL USE AND CARE

• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire 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 fire.
• 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, if that can make a connection from one terminal

to another. Shorting the battery terminals together may cause burns or a fire.

• 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.
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265^ (130^) may cause explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

SERVICE

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

SPECIFIC SAFETY RULES FOR CAULK AND ADHESIVE GUN

• Keep hands out of the piston and rod area of the caulk gun. Fingers can be pinched between the tube holder and the piston.
• Always use common sense and be cautious when using tools. It is not possible to anticipate every situation that could result in a dangerous outcome. Do not use this tool if you do not understand these operating instructions or you feel the work is beyond your capability; contact Milwaukee Tool or a trained professional for additional information or training.

• Maintain labels and nameplates. These carry important information. If unreadable or missing contact a MILWAUKEE service facility for a free replacement.

• AWARNING 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.

To determine the amount of charge left in the battery, turn the tool ON. The Fuel Gauge will light up for 2-3 seconds. When less than 10% of charge is left, 1 light on the fuel gauge will flash 4 times.

To signal the end of charge, 1 light on the fuel gauge will flash 8 times and the tool will not run. Charge the battery pack.

If the battery becomes too hot, the fuel gauge lights will flash and the tool will not run. Allow the battery to cool down.

Anti-Drip and Rod Release

The caulk gun features an automatic anti-drip to prevent drips after the trigger is released.

End of travel

When a tube is emptied, the motor will automatically reverse to release pressure, then shut off. Release the trigger and change the tube.

Overload

When an overload occurs, the tool will reach the maximum drive force and continue to hold this maximum force until the user releases the trigger. If material is not dispensing, make sure that:

• Nozzle tip is cut

• Caulk tube is not damaged or frozen

Rod is free of caulk/adhesive materials

Starting and Stopping and Controlling Speed

1. Pull trigger to dispense material.
2. Increase or decrease pressure on the trigger to dispense the material. Adjust the speed dial to select the maximum speed for proper bead width and material flow rate ("1" for slowest, "6" for fastest). The trigger pressure, selected speed, material type, temperature and nozzle diameter will all affect the flow rate. When using a tube or pack with a smaller nozzle diameter use a slower speed or the material may be forced around the rear tube seat.

NOTE: Operating the gun at high speeds may damage the dispensing tube or pack for some materials. For best results, gradually increase speed settings.

1. Release trigger to stop dispensing material.

NOTE: The piston will stop automatically when it has reached the end of the tube.

Using the Control Switch

The control switch may be set to two positions: forward and rack release. For forward, push in the control switch from the right side of the tool. The tool will run normally.

To lock the trigger and release the rack, push in the control switch from the left side of the tool. The rack can be moved to the desired position.
