When using the hammer drill mode for drilling into hard material like concrete, we recommend that you use
carbide-tipped percussion drill bits.
WARNING:
complete stop. Moving the mode selector while the drill is operating can cause damage
to the tool.
INSTALLING BITS
Inspect the drill bit shank and the drill's chuck jaws for dirt or foreign matter and clean them if necessary. Dirt on
the drill bit shank or on the chuck jaws can cause misalignment or bit slippage during use. Drill bits larger than
the hammer drill's maximum rated capacity may cause the motor to overload and/or gear damage.
WARNING:
adjusting, adding accessories, or checking a function on the tool. Failure to unplug the
tool could result in accidental starting causing possible serious injury.
To install a drill bit:
• unplug the hammer drill.
• Open the chuck jaws so the opening is slightly wider than the drill bit being installed.
• Position the drill so the chuck is pointing upward then insert the drill bit, allowing the bit to rest on the bottom
of the chuck. for small bits, insert the drill bit so that the bottoms of its flutes are even with the top of the
chuck jaws.
• Center the bit in the jaws and hand tighten the jaws by rotating the chuck collar clockwise, being sure the bit
is properly aligned in the chuck jaws.
• Insert the chuck key into one of three holes in the chuck, turning the chuck key clockwise to securely tighten
the chuck. Do not use a wrench, pliers, or means other than the chuck key to tighten or loosen the chuck.
To remove the drill bit:
• unplug the hammer drill.
• Loosen the chuck by inserting the chuck key into one of the three holes in the chuck and turn it counter-
clockwise.
• Remove the drill bit from the chuck.
WARNING:
chuck after each use.
SETTING THE DEPTH GAUGE
Mounted in your hammer drill auxiliary handle is a rod (8-fIG 1) called the depth gauge. Setting the depth gauge
gives you the ability to repeatedly drill holes to the same depth.
To Set the Depth Gauge:
• unplug the hammer drill.
• Turn the auxiliary handle and push the hex head of bolt off its socket to release the depth gauge rod.
• Measure backwards from the tip of drill bit the desired depth of holes, and then move the depth gauge so the
tip of the gauge is aligned with the desired drilling depth.
• Tighten the auxiliary handle and lock the depth gauge by turning the handle clockwise.
