GENERAL POWER TOOL SAFETY WARNINGS
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.
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 paints.
• Crystalline silica from bricks, cement and other masonry products.
• 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.
WARNING!
This product may contain lead, phthalates or other chemicals known to cause cancer, birth defects
and other reproductive harm. Please wash your hands after use.
WARNING!
Read all safety warnings and 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 electric (corded) power tool or battery-operated
(cordless) power tool.

GENERAL POWER TOOL SAFETY WARNINGS
• 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 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 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 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 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. 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 and in the
manner intended for the particular type of power tool, 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.

GENERAL POWER TOOL SAFETY WARNINGS
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.

VARIABLE SPEED TRIGGER SWITCH AND
LOCK-ON BUTTON (See Fig. A)
Depress trigger switch (3) to start and release it to stop your
metal shear. It is also a variable speed switch that delivers
higher speed with increased trigger pressure. Speed is
controlled by the amount of switch trigger depression.
When operating the metal shear for a period of time at its
fastest speed, the switch trigger can be locked in the ON
position, press the lock-on button (4) into the handle and the
tool will continue to run at its fastest speed.
To switch this tool off, simply squeeze and release the trigger
switch (3).
SHEARING (See Fig. B)
• Before cutting the “good” workpiece, make practice cuts
on a ”scrap” workpiece until you are comfortable with
operating the tool and with your ability to follow cutting lines.
• Place the shearing jaws of the tool at the edge of
workpiece.
• Squeeze the variable speed trigger switch (3) and gradually
move the blades into the material in desired direction.
NOTE: Before using the tool, read the instruction book carefully.
NOTE:
Maker sure the cutting jaws are aligned with the cutting mark, allow for adequate room for
the material being cut away. The cut line will be at least 1/16” (1.5 mm) wide.
NOTE:
The scrap piece that is being removed will normally curl out of the way.
OPERATING INSTRUCTIONS
WARNING!
Before shearing, make sure the work area is clear of any foreign objects and mark the shearing line
clearly on the workpiece. Secure small workpieces in a vise or on a stable platform.

ADJUSTING THE 360° SWIVEL HEAD (See Fig.
C1, C2)
When shearing large workpieces or curves, you may wish
to rotate the swivel head to reduce the interference with
the handle.
The cutting head can be rotated by 360o to allow the
handle to be positioned so that it will not interfere with the
shearing area.
Rotate the three screws (a1, a2, a3) counter-clockwise with
supplied hex key to unscrew the 360° swivel head screw.

MAINTAIN TOOLS WITH CARE
MAINTAIN TOOLS WITH CARE
Remove the plug from the socket before carrying out any adjustment, servicing or maintenance.
Your power tool requires no additional lubrication or maintenance. There are no user-serviceable parts in your power
tool. Never use water or chemical cleaners to clean your power tool. Wipe clean with a dry cloth. Always store your
power tool in a dry place. Keep the motor ventilation slots clean. Keep all working controls free of dust.
Periodically clear dust and chips from guard and base to ensure proper performance.
Occasionally you may see sparks through the ventilation slots. This is normal and will not damage your power tool.
If the supply cord is damaged, it must be replaced by the manufacturer, or similarly-qualified persons in order to avoid
a hazard.
