Safety Instructions

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

• a) Keep the 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 that may ignite dust or fumes.
• c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

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 the 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 the 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. The 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. The use of an RCD reduces the risk of electric
  shock.

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 influ-ence 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 energizing 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 jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry 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.

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 tools oper-ation. 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 per-formed. Use of the power tool for operations different from those intended could result in a hazardous situation.

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.

Functional Description

CAUTION! Before plugging in the tool, always check to see that the slide switch actuates properly and returns to the “OFF” position when the rear of the slide switch is depressed Switch can be locked in the ‘ON” position for ease of operator comfort during extended use. Apply caution when locking the tool in the “ON” position and maintain a firm
grasp on the tool. To start the tool, slide the slide switch toward the “I (ON)” position. For continuous operation, press the front of the slide switch to lock it. To stop the tool, press the rear of the slide switch, then slide it toward the “O (OFF)” position. Permissible shearing thickness The groove on the yoke serves as a thickness gauge for shearing mild or stainless steel plates. If the material fits within the groove, it is shearable. The thickness of materials to be sheared depends upon the type (strength) of the material.

Assembly

• CAUTION! Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
• Blade inspection
• Before using the tool, check the blades for wear. Dull, worn blades will result in a poor shearing action, and the service life of the tool will be shortened.
• Rotating or replacing blades
• Both the upper and lower blades have four cutting edges on each side (the front and back). When the cutting edge becomes dull, rotate both the upper and the lower blades 900 to expose new cutting edges.
• When all eight edges are dull on both the upper and lower blades, replace both blades with new ones. Each time blades are rotated or replaced, proceed as follows.

1. Hex wrench
2. Loosen
3. Upper blade securing bolt
4. Lower blade
5. Upper blade

Remove the blade securing bolts with the hex wrench provided and then rotate or replace the blades. Some tools have one washer between the upper blade and the blade holder. When the tool has a washer, be sure to use the thin washer when reassembling.
