NOTICE:

 

Never use “rotation with hammering” 

when the drill chuck is installed on the tool.

 The 

drill chuck may be damaged. 

Also, the drill chuck will come off when reversing the 

tool.

NOTICE:

 

Pressing excessively on the tool will 

not speed up the drilling.

 In fact, this excessive 

pressure will only serve to damage the tip of your drill 

bit, decrease the tool performance and shorten the 

service life of the tool.

Set the action mode changing knob to the   symbol.

Attach the chuck adapter to a keyless drill chuck to 

which 1/2"-20 size screw can be installed, and then 

install them to the tool. When installing it, refer to the 

section “Installing or removing drill bit”.
