running. The dial is marked 1 (lowest speed) to 5 (full
speed).
Refer to the table below for the relationship between the
number settings on the adjusting dial and the blows per
minute.

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing the bit (Fig. 3)
Clean the bit shank before installing the bit.
Insert the bit into the tool. Turn the bit and push it in until it
engages. (Fig. 4)
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
held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the way
and pull the bit out. (Fig. 5)

slide the change ring back to the original position. The bit
will be secured in place.
Hook (Fig. 8)
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 extension
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)
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.

unplugged before attempting to perform inspection or
maintenance.
