Tool Safety1. Before plugging in the heating inductor, make sure that the outlet voltage supplied is compatible with the voltage marked on the label and within 10% of the stated voltage. An outlet voltage incompatible with that specified on the label can result in serious hazards and damage to the heating inductor.2.Ensure attachment is securely located. Coil and main are firmly tightened before use.3.Do not use the heating inductor for longer than the stated duty cycle: 5 minutes on followed by 5 minutes off. The main circuit board has an overheat protection device, however the attachments do not have overheat protection so should not be used for more than 5 minutes of continued use.Operation1.To prolong your heating inductor, leaving an 10mm air gap between the coil and the work piece is recommended as the insulation of the coil will eventually burn through if held directly to hot material.2.Choose the appropriately sized coil to give the closest fit to the work piece.3.Insert both ends of the coil into the coil location socket and tighten the thumb screws securely.4.Activate the power switch to run the heating inductor for 1-3 minutes until enough heat has been applied to the work piece to break the rust/corrosion bond.5.Release the power switch to turn off the power.Features:1.Flameless Lossless Heating systemGreen&Safety1 minute Removal process/97%Lower power consumption by/1 cent removing 1 bolt only cost you 1 cent/1.9 Kg weight with2. adopt heat conduction technology, no flame, safe and environmental protection.
