Clean the bit shank before installing the bit.
Insert the bit into the tool. Turn the bit and push it in until
it engages.

If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the bit
again. Turn the bit and push it in until it engages.
After installing, always make sure that the bit is securely

► Fig.6: 1. Change ring
► Fig.7: 1. Change ring
The bit can be secured at 12 different angles. To
change the bit angle, slide the change ring forward,
then turn the change ring to change the bit angle. At the
desired angle, slide the change ring back to the original
position. The bit will be secured in place.
Hook
► Fig.8: 1. Hook 2. Power supply cord 3. Extension
cord
When connecting the power supply cord to an extension
cord, use the hook so that the plug of power supply cord
cannot be disconnected from the connector of exten-
sion cord. Set it on the extension cord 10 cm - 20 cm
away from the connector of the extension cord.

OPERATION

► Fig.9
Position the bit at the location to be chipped, then pull
the switch trigger. Apply slight pressure on the tool
so that the tool will not bounce around, uncontrolled.
Pressing very hard on the tool will not increase the
efficiency.
► Fig.10: 1. Scaling chisel 2. Tile
NOTE:
• When removing tiles with a scaling chisel, apply
the chisel to the bottom of tiles as shown in the
figure. If you operate the tool with the chisel
applied to the top surface of tiles, the service life
of the chisel will be shortened.

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.

or the like. Discoloration, deformation or cracks
may result.
