Drilling in Wood
A SDS PLUS to round shank adaptor chuck is required.
Ensure that tool is in drill-only mode. Start drilling with
slow speed and increase to full power while applying firm
pressure on the tool. Holes in wood can be made with the
same twist drills used for metal. These bits may overheat
unless pulled out frequently to clear chips from the flutes.
For larger holes, use spade bits, power auger bits, or hole
saws. Work that is apt to splinter should be backed up with
a block of wood.
Drilling in Masonry
When drilling in masonry, use carbide-tipped bits rated for
percussion drilling and be certain that the bits are sharp.
Use a constant and firm force on the tool to drill most
effectively. A smooth, even flow of dust indicates the proper
drilling rate.
Hammerdrill Operation (Fig. I)
1. Press the mode selector button
selector dial 4 to the hammerdrilling symbol.
2. When drilling, use just enough force on the hammer
to keep it from bouncing excessively or "rising" off the
bit. Too much force will cause slower drilling speeds,
overheating, and a lower drilling rate.
3. 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.
4. 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.
5. For masonry, use carbide-tipped bits or masonry
bits. A smooth even flow of dust indicates the proper
drilling rate.
Chipping and Chiselling (Fig. I)
1. Press the mode selector button
selector dial 4 to the hammering only symbol.
2. Insert the appropriate chisel and rotate it by hand to
lock it into one of 51 positions.
3. Adjust the side handle 1
4. Switch on the tool and start working.
5. Always switch off the tool when work is finished and
before removing the battery pack.
