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.

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.

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.
