The use on any material less than 25mm thick will

 

 

 

 

 

progressively reduce the magnetic performance. If

 

 

 

 

 

possible, substitute material should be positioned under

 

 

 

 

 

the magnet and work piece to equate to a suitable

 

 

 

 

 

material thickness. If this is not possible, an alternative

 

 

 

 

 

secure method of restraining the machine MUST be

 

 

 

 

 

used.

These tools are UK designed, and manufactured with globally sourced components and conform with the requirements of EEC Document HD.400.1 and BS.2769/84

Suitable only for a single phase 25-60Hz A.C. power supply

DO NOT USE ON D.C. SUPPLY

Do not use your magnetic drill on the same structure when arc welding is in progress. D.C. current will earth back through the magnet and cause irreparable damage.

WARNING: THIS APPLIANCE MUST BE EARTHED!

NB: ANY MODIFICATIONS TO THIS MACHINE WILL INVALIDATE THE GUARANTEE
