 Ring

Hold the ring and turn the sleeve counterclockwise to 

open the chuck jaws. Place the bit in the chuck as far as 

it will go. Hold the ring irmly and turn the sleeve clock

-

wise to tighten the chuck. To remove the bit, hold the 

ring and turn the sleeve counterclockwise.
Set the action mode changing knob to the 

 symbol.

You can drill up to 13 mm diameter in metal and up to 
32 mm diameter in wood.

CAUTION:

  

• 

Never use "rotation with hammering" when the 

quick change drill chuck is installed on the tool. 

The quick change drill chuck may be damaged.

 

Also, the drill chuck will come off when reversing the tool.

• 

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 bit, decrease the tool 

performance and shorten the service life of the tool.

• 

There is a tremendous twisting force exerted 

on the tool/bit at the time of hole breakthrough. 

Hold the tool irmly and exert care when the bit 

begins to break through the workpiece.

• 

A stuck bit can be removed simply by setting 

the reversing switch to reverse rotation in order 

to back out. However, the tool may back out 

abruptly if you do not hold it irmly.

• 

Always secure small workpieces in a vise or 

similar hold-down device.

MAINTENANCE

CAUTION:

  

• 

Always be sure that the tool is switched off and 

the battery cartridge is removed before attempt

-

ing to perform inspection or maintenance.

• 

Never use gasoline, benzine, thinner, alcohol 

or the like. Discoloration, deformation or cracks 

may result.

To maintain product SAFETY and RELIABILITY, 

repairs, carbon brush inspection and replacement, any
