8. For drilling into brick

CAUTION:

䢇 When the hammer drill is used continuously, the body may be heated. If this happens,

leave the hammer drill to cool.

䢇 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 hammer drill within 20 – 30 lbs. (10 – 15 kg) pressing force while drilling into

brick.
