Maintenance; Motor Brushes - DeWalt D25413 Instruction Manual

2. Drill straight, keeping the bit at a right angle to the work. Do not
exert side pressure on the bit when drilling as this will cause
clogging of the bit flutes and a slower drilling speed.
3. When drilling deep holes, if the hammer speed starts to drop off,
pull the bit partially out of the hole with the tool still running to help
clear debris from the hole.
4. For masonry, use carbide-tipped bits or masonry bits. A smooth
even flow of dust indicates the proper drilling rate.
Chipping and Chiselling (Fig. 1)
1. Set the mode selector switch (G) to the hammering only position.
2. Insert the appropriate chisel and rotate it by hand to lock it.
3. Adjust the side handle (C) as required.
4. Be sure chisel is in contact with work surface before depressing
the trigger switch.
5. Always fully release the trigger switch when work is finished and
before unplugging.
