Maintenance and inspection  
1.After each use, be sure to clean up the unit. Powder plaster, dust and dirt stuck on the unit may get it in  
trouble.  
2.To wipe the unit clean, use dry cloth or neutral detergent-soaked cloth. Do not use gasoline, thinner or the  
like, which would damage the unit. Never wash the unit in water, which would get it rusty or malfunctioning.  
3.The bit of the specific adaptor kit is consumable. If its both heads have worn out, immediately replace it  
with new one. Worn-out bit may cause poor tightening or damage the screw head.

unit on.  
5.Do not disassemble and repair the unit yourself. For repairs, contact your dealer.
