Kasei KZ-4000BC-PRO-2S, Operator'S Manual

This reaction is called blade thrust. As a result, 

the operator may lose control of the unit which 

may cause serious or fatal injury. Blade thrust 

is more likely to occur in areas where it is diffi 

cult to see the material to be cut.

Wear the harness as shown in the fi gure. The 

blade turns counter-clockwise, therefore, be 

advised to operate the unit from right to left for 

effi cient cutting. Keep onlookers out of working 

area at least 15 m.

Use in accordance with local laws and 

regulations.
