Safety Precautions and 
Working Techniques

machine may be hazard-
ous. Because a cut-off

ates sparks during the

safety precautions must 
be observed to reduce 
the risk of personal injury 
and fire.
It is important that you 
read, fully understand 
and observe the following 
safety precautions and 
warnings. Read the 
instruction manual and 
the safety precautions 
periodically.
