4. Press the centering bit firmly against your center
mark, hold the tool firmly and pull the trigger.
NOTE: If the 48-20-5099 threaded stud is used,
or a center pin and guide plate are not available,
use a template or notched board to start the hole.
5. Start the tool. After drilling to about the depth
of the core bit teeth, remove the center pin and
guide plate from the core bit (not necesary for LHS
system). Resume drilling.
6. To change the core bit, hold the tool upwards,
pointing it away from your body, and run it briefly
in forward to loosen the core bit from the adapter.
NOTE: To make deeper holes, remove the core bit,
break and remove the core, then resume drilling.
When drilling long or deep holes, after each inch
of penetration pull the bit partially out of the hole
while the tool is running, to help clear dust from
the bit flutes. Dust can clog the bit flutes and can
make the bit bind in the hole. If this occurs, stop
the tool, free the bit and begin again.
Setting Self-Drilling Anchors
MILWAUKEE Tooth Anchor Chucks require a "B"
taper adapter.
1. Place the proper size tooth anchor chuck into the
"B" taper adapter. Then insert the "B" taper adapter
into the tool and lock it into place as described.
See "Installing Bits and Chisels".
2. Insert the anchor into
the tooth anchor chuck.
Set the knob for ham-
mering only. Set the
anchor on your mark
and hammer until the
teeth have penetrated
the concrete.
3. Set the knob for ham-
mering with rotation
and drill until the chuck
is 1/8" above the con-
crete.
NOTE: It may be nec-
essary to clean dust
and cuttings from the
anchor several times
while drilling the hole.
4. Remove the anchor
from the hole while the
tool is running. Clean
the dust and cuttings
from the anchor by
pointing it downward
and turning the tool on
and off several times. Clean the dust out of the
hole with a vacuum cleaner or blowout bulb.
5. Place the expansion plug into the anchor and insert
the anchor into the hole. Switch the knob back to
hammering only, and hammer the anchor firmly
into the hole.
6. Snap the head off of the
anchor. To remove the
head of anchors up to
5/8", grasp the handles
firmly and pull the tool
sharply towards you or
snap off the anchor
head with a hand ham-
mer as shown. The
anchor is now ready to
receive a bolt.
7. To remove the anchor
head wedged in the
tooth anchor chuck,
use a drift pin.
8. To remove the tooth
anchor chuck, remove
the "B" taper adapter from the nose of the tool.
Insert the drift pin supplied with the adapter into
the hole on the side of the "B" taper adapter and
strike it sharply to force out the tooth anchor chuck.
MILWAUKEE Rotary Hammers may be used for
chipping and chiseling. A variety of accessories are
available.
When chiseling, hold the tool at an angle to the
workpiece. Work from a corner or close to the edge
of the workpiece, breaking off one small area at a
time rather than attempting too large an area.
WARNING
1/8"
battery pack from the charger or tool before
performing any maintenance. Never disassemble
the tool, battery pack or charger. Contact a
MILWAUKEE service facility for ALL repairs.
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program.
Inspect your tool for issues such as undue noise,
misalignment or binding of moving parts, breakage of
parts, or any other condition that may affect the tool
operation. Return the tool, battery pack, and charger
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the
tool, battery pack and charger to a MILWAUKEE
service facility for inspection.
If the tool does not start or operate at full power with
a fully charged battery pack, clean the contacts on
the battery pack. If the tool still does not work prop-
erly, return the tool, charger and battery pack, to a
MILWAUKEE service facility for repairs.
WARNING
your tool, battery pack or charger in liquid or
allow a liquid to flow inside them.
Clean dust and debris from any vents. Keep tool
clean, dry and free of oil or grease. Use only mild
soap and a damp cloth to clean, since certain clean-
ing agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated
cleaning solvents, ammonia and household deter-
gents containing ammonia. Never use flammable or
combustible solvents around tools.
