Project Description

How to use automatic rebar bending machine GW40D and GW50D (manuals of GW40D and GW50D rebar bending machine)

  • Before using the automatic rebar bending machine, so please read this operating manual carefully

Specification of automatic rebar bending machine

  • Machine ModelGW40DGW50D
    Round barØ4mm-Ø40mmØ4mm-Ø50mm
    Motor Power3Kw4Kw
    Motor Speed1450RPM1450RPM
    Package Dimension850*850*800mm950*850*800mm

Fill machine oil

  • First of all,open workbench cover, then fill machine oil through oil hole
openable working platform of GW50D

Control panel introduction

  • Green indicator: this is indicator of automatic mode, and if machine is working in automatic mode, the indicator will be light
  • Touch startup buttons: the two buttons are startup buttons, and they are available when the machine is working in manual mode,
  • Mode switch: Automatic or Manual, due to the mode which you transite to
  • Reverse switch: this is power reverse switch
  • GW40D and GW50D are multifunctional,
  • You can use it as automatic mode, automatic mode is better for angle degree presetting, and it is better for heavy duty repetition rebar bending works
  • You can also use it as manual mode, manual mode is auxiliary function, it’s better for pieces of bending works.
Control panel


  • Connect power line 380V three phase,
  • If you use Automatic mode, so touch footswitch for bending,
  • If you use Manual mode, so touch startup buttons for bending
  • Since commissioning is ok, finally you can go ahead with heavy duty works
footswitch for rebar bender

How to set angle degree (in automatic mode and in manual mode)

  • Automatic working mode: fixing indexing pins into the holes ( which angle degree you need),then touch footswitch,finally machine will bend rebar itself
  • Manual mode: controlling angle degree manually by press startup buttons
indexing pins of GW40D

Matters need attention

  • Power source should meet machine power requirement, 380V three phase,
  • If the machine power is customized, do it as customized power source
  • You have to keep machine oil in proper level
  • Operator has to use machine under its load capacity,
  • You have to use machine in safety situation
  • If operator is skilled, it will be better
