Common sense and caution are factors which cannot be built into any product. These factors must be supplied by the operator. Please remember:

  • - Prevent body contact with grounded surfaces such as pipes, radiators, etc.
  • - Stay alert. Never operate equipment or use tools if you are tired.
  • - Do not use this product if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgement or reflexes might be impaired.
  • - Do not wear loose clothing or jewelry as they can be caught in moving parts.
  • - Non-skid footwear is recommended.
  • - Wear restrictive hair covering to contain long hair.
  • - Use eye and ear protection. Always wear ANSI-approved safety glasses when using equipment or tools.
  • - Keep proper footing and balance at all times.

Work Area

To avoid risk of personal injury, equipment damage, fire and shock, make sure work area is:

  • - Free of damp, wet, or slippery conditions.
  • - Free of flammable gasses or liquids.
  • - Free of children. Children should never handle tools or operate equipment.
  • - Make sure your work area is well lighted.
  • - Clean and uncluttered work spaces contribute to safe and productive work conditions.

Before Operating

  • Check for damaged parts. Before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function.

  • Check for alignment and binding of all moving parts, broken parts or mounting fixtures and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician.


  • - Never force the tool or attachment to do the work of a larger industrial tool. It is designed to do the job better and more safely at the rate for which it was intended.
  • - Never use the blades if they are dull, worn, or chipped. Blades must be sharpened, repaired, or replaced before using.
  • - Check to make sure all bolts are secure but not over-tightened. Check for blade clearance. Make sure clearance is suitable for the workpiece.
  • - While being used, the lower blade must be tightened. When not being used, the Clamp (#10) can be loosened.
  • - Minor assembly of the Throatless Shear is required. Assemble the Handle (#6) over the exposed shaft of the Geared Handle (#4) and tighten bolt (#5).

Using The Throatless Shears

  1. Adjust the clearance between the Upper Blade (#14) and Lower Blade (#8). To decrease the clearance, turn the Adjusting Bolt (#15) clockwise. To increase clearance, turn the bolts counter-clockwise. The clearance can be adjusted to between 1/4 and 1/10 of the thickness of the workpiece.

  2. To gain power and control of the workpiece, start all cuts at the the heels of the blades. Circular and irregular cuts are made by turning the wokpiece while following through with the downward stroke of the blade.

  3. When a cut has been finished, push the workpiece forward while raising the handle to lift the blade above the workpiece. Start the next cut at the heel of the blade.

  4. Always keep the material being cut flat on the bed of the shear.


Periodically use a good Graphite Oil to lubricate blade edges and gears on the Geared Handle (#4).
