When the hammer drill is used continuously, the body may be heated if this happens,
leave the hammer drill to cool.
䢇
If the hammer drill is used continuously to drill more holes than specified in Table 4, the

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.
