7. For drilling into brick
CAUTION:
When drilling brick continuously, the number of holes to be drilled should be less than
specified in Table 4.
When the hammer drill is used continuously, the body may be heated if this happens,
leave the hammer drill to cool.
If the hammer drill is used continuously to drill more holes than specified in Table 4, the
motor will be burnt.
Excessive pressing force never increases drilling speed. It will not only damage the drill
tip or reduce working efficiency, but could also shorten the service life of drill bit.
Operate the hammer drill within 10-25 kg pressing force while drilling into brick.
