13. For drilling into brick <DV18DL>

CAUTION:

●When the Cordlless hammer drill is used continuously, the body may be heated. If this happens, leave the Cordlless hammer drill to cool.

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

CAUTION:

●While operating the Cordless hammer drill, take care not to lock the motor. If the motor is locked, immediately turn the power off.

If the motor is locked for a while, the motor or battery will be burnt.

●Do not tighten too strongly as the screw heads will be damaged.

●To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. Therefore, when used as a drill, if the tool is overloaded, the motor may stop. However, this is not the trouble but the result of protection function. In this case, release the switch of tool and eliminate the causes of overloading.
