Safety Instructions
- Keep the 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.
- 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. - 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 the 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.
Operate
- Plug the G tool into the appropriate power supply.
- Ensure that the tool is in a safe location away from the user and any other objects. Slide the power switch located at the top of the tool forward to turn the tool on. The upper blade will begin to oscillate.
- Align blades on the line to be cut and apply pressure to begin cutting (FIG. 1). Only moderate pressure is required for the tool to cleanly cut through metal. Do not force. When possible, it is recommended to use two hands to control the tool.
- To make a curved cut, apply pressure in the direction needed to follow the curve. If the tool begins to bind, STOP IMMEDIATELY. Do not force the tool. Remove all excess material before attempting to continue the curved cut.
SETTING THE CUTTING BLADE GAP
To determine the ideal blade gap for a given project, the material thickness must be considered. For optimum performance, the blade gap should be adjusted whenever the material type or thickness is changed.
If you find the material being sheared is bending excessively, rather than shearing, it is recommended to reduce the blade gap. If it is binding rather than shearing, increase the lade gap. Make small adjustments and test on scrap pieces of material before cutting your workpiece.
| Thickness | Recommended Gap |
| 22GA (.0312”) | .006” |
| 20 GA (.0375”) | .0075” |
| 18 GA (.050”) | .010” |
| 16 GA (.0625) | .0125” |
| 14 GA (.078”) | .016” |
Unplug the tool before making any adjustments or repairs.
- With the tool unplugged, apply pressure to the upper blade to move it to its highest position.
- Measure the gap between the upper and lower blades using a feeler gauge (not included) (FIG 2).
- If adjustment is necessary, loosen the cap EASTWOOD 20644 Throatless Electric Metal Shear screw fastening the lower blade slightly, loosen the lock nut, and use the adjustment screw to adjust the gap (FIG 3).
- When the desired gap is achieved, tighten the cap screw and lock nut, ensuring the desired blade gap is maintained.
Blade
- Note the orientation of the blade set before EASTWOOD 20644 Throatless Electric Metal Shear disassembly. The replacements must be installed
in the same orientation for proper function. - Remove upper and lower shear blades.
- Install new shear blades and set blade gap (See section: Setting Cutting Blade Gap).
- Test for the proper operation of the heart
Brush
- Loosen and remove the Brush caps located on the sides of the tool (FIG. 4).
- Remove old brushes and install new brushes in the same orientation.
- Install Brush caps
- Connect the tool to the appropriate power source and test for correct operation. Allow the tool to run for two minutes; this will allow the new brushes to seat.
Maintainance
- Apply several drops of light machine oil occasionally to moving contact surfaces.
- Add 3-4 drops of light machine oil after each use to the oil port located on the top of the Tool.

FAQs
What materials can I cut with this shear?
Copper, aluminium, mild steel, and other non-ferrous metals can all be cut. Although thickness capacity varies depending on the material, it usually comprises up to 16-gauge aluminium and 18-gauge steel.
What does “throatless” mean in this tool?
“Throatless” refers to the tool’s ability to cut through material without restriction. It is perfect for intricate curves and unique designs since it permits unrestricted movement of the sheet in any direction.
Is it safe and easy for beginners to use?
Yes, it is consistent and easy to use due to its electric operation. New users should, however, always adhere to safety precautions and start with waste material.
How do I set up the shear for the first time?
Place the shear firmly on a sturdy stand or workstation.
How do I guide the metal during cutting?
Gently move the sheet along your cut line with both hands. Avoid pushing the material to avoid warping or damaging the blade, since the revolving blades will cleave the metal cleanly.
Can I buy replacement blades for this shear?
Yes, authorised dealers or the EASTWOOD website offer replacement blades and other consumables. To keep cutting performance, always use OEM parts.
Where can I find technical support or order parts?
Through their customer service line or website, you can get in touch with EASTWOOD’s technical support staff. They provide help with replacements, repairs, and usage advice.
