OPERATING
INSTRUCTIONS
NOTE:
Before using the tool, read the
instruction book carefully.
Intended Use
The machine is intended for impact drilling in
brick, concrete and stone as well as for drilling in
wood, metal and plastic.
1. ADJUSTING THE AUXILIARY HANDLE (SEE
A1 )
For your personal safety we recommend using
the auxiliary handle at all times.
To adjust the handle, rotate the bottom of the
handle anticlockwise and rotate the handle
around the hammer collar until the handle is in
the desired position. Tighten fully.
2. USING THE DEPTH GAUGE (SEE A2)
The depth gauge can be used to set a constant
depth to the drill.
Depress the locking screw on the top of the
handle to loosen, insert the depth gauge into the
handle. Adjust it to the desired depth. Release
the locking screw to tighten.
3. FITTING BITS OR CHUCK (SEE B)
Clean the bit shank and apply grease before
installing the bit. Hold the rotary grip, pull back
the lock sleeve and insert the bits or chuck into
the bit holder. Turn the bit and push it in until a
resistance is felt. The shaft drops completely into
the bit holder. Once you are satisfied that it has
been seated, release the black lock sleeve. This
would lock the bits or chuck into position.
After installing, always make sure that the tool or
chuck is securely held in the bit holder by trying
to pull it out.
If the bits or chuck is not located well, repeat the
operation again.
4. REMOVE BITS OR KEY CHUCK (SEE B)
To remove the tool or chuck, pull back the locking
sleeve, hold and pull the tool or chuck out.

The bits or chuck are gripped firmly by
the shank and can not be removed once locked
