Operation
Position the bit at the location to be chipped, then
pull the trigger.Apply slight pressure on the
machine so that the machine will not bounce
around, uncon-trolled. Pressing very hard on the
machine will not increase the efficiency.
NOTE:
When removing tiles with a scaling chisel, apply
the chisel to the bottom of tiles as shown in Fig.6.
If you operate the machine with the chisel applied
to the top surface of tiles, the service life of the
chisel will be shortened. (Fig. 6)
