1. REPAIR GUIDE
Without fail, remove Type FEB 9 Battery from the main body of the tool before attempting repair work. Because
the tool is cordless, if the battery is left in and the switch is activated inadvertently, the motor will start rotating
unexpectedly and could cause serious injury.
1-1. Precautions in Disassembly and Reassembly of the Main Body
The [Bold] numbers in the descriptions below correspond to the item numbers in the Parts List and exploded
assembly diagram.

the right [clockwise].)
(d) Insert an M10 hex. bar wrench into the Drill Chuck [8], and strike it gently in a counterclockwise direction
