Overview

A rebar bender bends reinforcing steel around a former to a set angle, so every bar in a batch comes out identical.

Stirrups and ties, hooks and 90° bends, column and beam cages, and any job with the same bend repeated many times over.

Set the angle stop before bending and test on an offcut. Steel springs back a little when it is released, so the stop usually has to sit slightly past the angle actually wanted.

That spring-back is the whole skill. One test bar at the start saves re-bending a day's worth at the end.

Troubleshooting

Bends come out at the wrong angle

Checks to try, in order

  1. Re-set the angle stop.
  2. Allow for spring-back — bend slightly past the target angle.

Reference draft — always follow the manufacturer’s manual.

Bar slips during the bend

Checks to try, in order

  1. Fit the correct pins or rollers for the bar diameter.

Tool won't switch onShared · Electric (corded)

Likely causes

  • Tripped GFCI or breaker
  • Lock-off button
  • Damaged cord
  • Dead outlet

Checks to try, in order

  1. Check the outlet works and reset any GFCI / RCD that has tripped.
  2. Release the lock-off button or safety switch before squeezing the trigger.
  3. Inspect the cord and extension lead for cuts, crushed sections or damaged plugs.
  4. If running from a generator, make sure it's running and its breaker hasn't tripped.

A damaged cord or plug means the tool is out of service. Tag it and return it — never tape a cord.

Reference draft — always follow the manufacturer’s manual.

Keeps tripping the breakerShared · Electric (corded)

Likely causes

  • Circuit overloaded
  • Undersized extension cord
  • Blunt accessory

Checks to try, in order

  1. Plug into a circuit with nothing else heavy running on it.
  2. Use a shorter, heavier extension cord. Long, thin cords starve the motor and trip breakers.
  3. Don't force the tool — a dull bit, blade or disc makes the motor draw more current.

Reference draft — always follow the manufacturer’s manual.

Overheating, burning smell or heavy sparkingShared · Electric (corded)

Checks to try, in order

  1. Stop and unplug the tool.
  2. Check the motor vents aren't blocked with dust.
  3. Let it cool, fit a sharp accessory and let the tool's weight do the work.

Heavy sparking from the vents or a burning smell that returns points to worn brushes or a failing motor — workshop only.

Reference draft — always follow the manufacturer’s manual.

Safety

  • Keep hands clear of the bending disc and pins.
  • Watch the swing path of long bars.

For electric (corded)

  • Inspect the cord and plug before every use. Use a GFCI/RCD outdoors or near water.
  • Unplug before changing blades, bits, discs or pads.
  • Wear eye protection, and a dust mask when cutting, grinding or sanding masonry.
