GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings, instruction, illustrations and specification 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 (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 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 residual current device (RCD) protected supply. Use of a 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 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 energising 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 and clothing 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. 
• 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, 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 behaviour 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 130°C (265°F) 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 authorised service providers.

OPERATION

Do not use damaged dies. Using damaged dies could result in serious personal injury.
Keep hands away from moving die and ram head while tool is in use. Fingers could be crushed, fractured, or amputated.
Always wear proper eye protection marked to comply with AS/NZS 1337.1.
When working in dusty situations, wear appropriate respiratory protection or use a suitable dust extraction solution.

To avoid damage to the tool, do not operate the tool without the die retaining pin fully inserted and locked into die. Damage to the cylinder or clevis may occur.

Lubrication

The top and bottom die channel faces (see “Functional Description”) of the strut shear clevis must remain well lubricated throughout life to prevent die binding. Regularly lubricate the top and bottom die channel faces with a generous amount of Type “E” Grease. Always lubricate the top and bottom die channel faces before die installation. If the strut shear die does not fully retract, closely inspect the clevis for cracked or broken parts. If no issues are found, the dies and clevis should be cleaned, re-greased, and the tool cycled to ensure functionality.
NOTE: If the die gets stuck in the extended position, remove battery pack to avoid starting the tool. Gently tap the die back to the fully seated position, disengage the return arm, clean out the dies, and ensure the die channel within the clevis is clean of debris. Relubricate.

Inserting/Removing Dies

Inspect dies and strut before use. Do not use damaged dies. Using damaged dies could result in serious personal injury. Only use properly matched dies. Refer to “Accessories” for die compatibility. To maximize die life, swap the cutting edge of the dies periodically.

To insert :

1. Remove battery to avoid starting the tool.
2. Pull and hold the return arm outward to slide the first die into the stationary pocket.

3. With the return arm still pulled out, insert the second die beside the first.
NOTE: Some die sizes have two die retaining pin holes. Those dies can be inserted facing up or down.

4. Release the return arm back into place ensuring die retaining pin is properly seated into the die.

To remove :

1. Remove battery to avoid starting the tool.
2. Pull and hold the return arm outward and slide both dies out.

Shearing

Before shearing:

Inspect the dies for cracks or other damage. Do not use damaged dies. Using damaged dies could result in serious personal injury.
Do not shear stainless steel. Cutting improper material may damage the shear head or result in serious personal injury.

• Ensure die retaining pin is properly seated and dies are properly installed.
• Dies must be used in an APPROVED COMBINATION of die and strut. Improper combinations can result in a faulty shear.
• Inspect and discard workpieces with unacceptable defects.

1. Insert the battery pack.

2. Insert the strut in to the installed dies.
   NOTE: When shearing strut channel, the work piece must always be supported by the strut support plate. The strut support plate is designed to support the strut during the shearing operation and is needed to produce the cleanest possible shear. The strut support plate is positioned 100 mm (4″) off the shearing plane. The tool sits at a height that specifically allows the free end of a strut to be supported by a piece of 41 mm (1-5/8″) strut when used on a flat surface. It is not recommended to cut anything shorter than a 125 mm (5″) piece of strut. The squareness of the cut piece will be compromised.

3. Ensure the tool is secured either to a table, stand, or other flat and stable surface. Slide the trigger lock-off switch to the unlock position. Pull the trigger halfway to activate the LED worklight. Pull the trigger all the way to start the strut shear.

4. Once the strut is sheared, release the trigger to maximise tool life allowing the tool ram head “dead head” (continue to push to the full extent it can) and return on it’s own will unnecessarily stress the ram and potentially reduce the life of the tool.
   NOTE: If the die gets stuck in the extended position, refer to “Lubrication”.

5. If service is needed, the LED work lights will blink repeatedly. After 2000 cuts are made with the work light blinking, the tool will permanently shut off until service is performed by a MILWAUKEE® service facility.

Backup Release Valve

If the ram head must be returned without the battery pack installed, press and hold the backup release valve. Hold tool securely until the ram head retracts fully.

Optional Mounting

The strut shear can be attached to the MILWAUKEE® 152MM (6″) LEVELING TRIPOD CHAIN VICE (MPS), other suitable stands, or be screwed down to a secured work surface via a suitable fixing installed through the 5 mm hole located in the tri-stand chain mount.

MAINTENANCE

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.

Dies and Clevis

Inspect the dies for cracks or other damage. Do not use damaged dies.
Using damaged dies could result in serious personal injury. Ensure the die channel within the clevis is clean of debris before each use.
Hot-dipped galvanised strut may have beads or other imperfections from the plating process that will cause additional resistance when inserting the strut into the dies. These would need to be removed prior to attempting to insert the strut into the dies.

Maintaining Tool

Keep your tool, battery pack and charger in good repair by adopting a regular maintenance program. Inspect your tool for issues such as undue noise, misalignment or binding of moving parts, breakage of parts, or any other condition that may affect the tool operation. Return the tool, battery pack, and charger to a MILWAUKEE® service facility for repair. After six months to one year, depending on use, return the tool, battery pack and charger to a MILWAUKEE® service facility for inspection.
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 properly, return the tool, charger and battery pack, to a MILWAUKEE® service facility for repairs.
NOTE: If service is needed, the LED work lights will blink repeatedly. After 2000 cuts are made with the work light blinking, the tool will permanently shut off until service is performed by a MILWAUKEE® service facility.
