• Check voltage of the power line. 

Machine will not work if the voltage is 

too low or too high. Machine will start 

automatically only if voltage returns back 

to normal level.

• Ensure that there is no short circuit on 

the output of the machine. Otherwise 

eliminate the defect.

• All connections of the welding circuit 

must be operational, and functional 

terminal must be securely fixed to the 

work piece to be welded.

CAUTION

When using the drill follow these rules:

• do not allow mechanic damage (bumps, 

falls etc.); 

• protect the tool from external sources of 

heat and chemically active substances, as 

well as liquid and objects penetration;   

• provide effective cooling and wastes 

withdrawal from the tool working zone;

• before disconnecting the tool from the 

power source turn off the On/Off switch; 

WARNING! Repair, modification 

and check of ZENIT power tools should 

be performed only in authorized service 

centers ZENIT. While use or maintenance 

of power tools follow all safety rules and 

standards.

NOTE

Zenit Power Tools are constantly being 

improved and modified to incorporate the
