2. INTRODUCTION & SPECIFICATION
2.1.
Introduction
The SM658 complies with requirements of the Machinery Safety Directive 98/37/EC and is fully CE approved. The bandsaw has a heavy-duty
cast base and a swivel arm with a fully guarded blade for horizontal and vertical cutting of light metals. A magnetic no-load voltage switch
prevents the motor from re-starting in the event of a power failure or a blade jam. An oil-bath gear box and sealed-for-life drive bearings give
fast and smooth operation. Fully adjustable precision blade guides provide accuracy and long blade life. The saw may be bench mounted or
fitted to the optional stand, Model No. SM658/ST, which is available from your Sealey agent.
