Worn out power tools and accessories 

contain considerable amounts of valuable 

raw and rubber materials, which can be 

recycled. 

These instructions are printed on paper 

produced with elemental chlorine-free 

bleaching process.

failure: 

-

 

switch on again. 

No mains voltage 

-

 

Check cables, plug, outlet and mains 

fuse. 

Motor overheated, e.g. by a blunt band 

saw blade or chip build-up in the housing:

Load too high: 

-

 

reduce pressure against band saw 

blade (reduced feed speed).   

Incorrect band saw blade: 

-

 

replace band saw blade (see "Care 

and maintenance"): 

thin stock = 

narrow band saw blade, 

thick stock =
