SAFETY
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.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) 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.
e) 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.
f) 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.
3) Personal safety
a) 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.
b) 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.
c) 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f) 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.
g) 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.
4) Power tool use and care
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) 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.
5) Service
a) 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.
SPECIFIC SAFETY RULES AND SYMBOLS
- Wear ear protectors.

Exposure to noise can cause hearing loss.
-
Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

To ensure safer operation of this power tool, metabo HPT has adopted a double insulation design. “Double insulation” means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator.
Therefore, either the symbol “☐” or the words “Double insulation” appear on the power tool or on the nameplate.
Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments.
To keep the double insulation system effective, follow these precautions:
○ Only metabo HPT AUTHORIZED SERVICE CENTER should disassemble or assemble this power tool, and only genuine metabo HPT replacement parts should be installed.
○ Clean the exterior of the power tool only with a soft cloth moistened with soapy water, and dry thoroughly.
Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve.

ASSEMBLY AND OPERATION
APPLICATIONS
☐ For shearing steel plate, brass plate, copper plate, aluminum plate, stainless steel plate, tin plate, and other metal plates, also leather and fiberboard.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms to the power source requirements specified on the product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while the switch is in the ON position, the power tool will start operating immediately and can cause serious injury.
3. Extension cord
When the work area is far away from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

Damaged cord must be replaced or repaired.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs.
If such a faulty receptacle is used, it may cause overheating, resulting in a serious hazard.
5. Confirming condition of the environment:
Confirm that the work site is placed under appropriate conditions conforming to prescribed precautions.
- Adjusting the horizontal gap between the shearing blades
Adjust the horizontal gap between the shearing blades (A in Fig. 2) at approximately 1/10 the steel plate thickness to be sheared, according to the following procedures. (Fig. 3)

Thickness Gauge Stationary Blade Lock Nut M4 Slotted Set Screw M4×14 Hexagon Socket Hd. BoltFig. 3
(1) Loosen the hexagonal socket bolts fastening the stationary blade. Loosen the M4 lock nut, and push back the M4 slotted set screws slightly.
(2) From the supplied thickness gauges, select one that is 1/10 the thickness of the panel to be cut. Thickness of each thickness gauge is marked thereon. Insert the gauge in between the blades, then tighten the hexagonal socket bolts very loosely. Next, use a screwdriver to turn the M4 slotted set screws to position the stationary blade until it hits the thickness gauge.
(3) If the space between blades is larger than the thickness of the panel to be cut, there will be burrs for a less than clean cut.
If the space between blades is too narrow, cutting speed will be affected. For cutting in a curved line, making the space a little bigger will make the cutting easier.
(4) After adjustment, tighten the M4 nuts securely so they will not loosen during operation.
(5) Securely tighten the hexagonal socket bolts fastening the stationary blade.
HOW TO USE
CAUTION:
○Do not attempt to cut panels of thicknesses that are beyond the capability of the hand shear. Doing so will result in premature breakage of the hand shear.
○Perform the cutting operation only after the panel is fixed securely.
When cutting thin panels, level the unit horizontally, as shown in Fig. 4.
To facilitate smooth cutting of thick panels, if the cut-off side goes toward the left, (Fig. 4) raise the rear of the unit slightly. And if the cut-off side goes toward the right, lower the rear of the unit slightly.
HOW TO REPLACE THE BLADE
The hand shear uses disposable blades. Each blade has 8 cutting edges, as shown in Fig. 5. After a cutting edge cuts 1300 ft.(400m) of panel, cutting performance will fall. Then use another cutting edge. After all 8 cutting edges are used and worn, replace the blade.

MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection.
1. Inspecting the blade
Using a worn or chipped blade will put an excessive burden on the motor and affect work performance. Therefore, always use a well-cutting blade.
2. Inspecting the screws
Regularly inspect all screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately.
⚠ WARNING: Using this Hand Shear with loosen screws is extremely dangerous.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 6)
The motor employs carbon brushes which are consumable parts. When they become worn to or near "wear limit", it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush No. shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
CAUTION:
Using this Hand Shear with a carbon brush which is worn in excess of the wear limit will damage the motor.
