3. Insert the adapter into the nose of the tool (see
"Installing Bits and Chisels". Set the action selec-
tor to the hammering-with-rotation setting.
4. Press the center pin fi rmly against your center
mark, hold the tool fi rmly and pull the trigger (Fig. 6).
NOTE: If a center
pin and guide plate

are not available,
use a template or
notched board to
start the hole (Fig. 7).
5. After drilling to
about the depth of
the core bit teeth,
remove the center
pin and guide plate
from the core bit.
Resume drilling.
6. To change the core
bit, hold the tool

it away from your
body, and run the
tool allowing rota-
tion and impacting
for about fi ve sec-
onds to loosen the
core bit from the
adapter shank.
NOTE: To make
deeper holes, re-
move the core bit,
break and remove
the core. Resume
drilling. When drill-
ing 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 fl utes. Dust can
clog the bit fl utes and can make the bit bind in
the hole. If this occurs, stop the tool, free the bit
and begin again.
Drilling Large Diameter Holes with Core Bits
When drilling holes with large diameter core bits,
dust may build up in the cut and can cause the tool
to stall, bind, or cut slowly. By creating an opening
for the dust to escape, drilling time, bit stress, and
tool stress can be reduced.
1. Start the cut as normal.
2. Once the bit is fi rmly established in the cut (about
1/4" deep), remove the bit from the cut (Fig. 8).
3. Remove the bit from

Chiseling and Chipping
These MILWAUKEE Hammers may be used for
chipping and chiseling.
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.
A variety of accessories are available.
Bushing Tools-Used to surface
concrete.
Mortar Cutting Chisels (Seam
Tools)-For removing old mortar for
tuck pointing or caulking.
Bull Points-For demolition work
and starting holes in concrete
slabs.
Flat Chisels-For edging, chipping
or channeling.
Scaling Chisels-For removing
weld spatter or scale and cutting
straight lines.
Slotting Chisel-For slotting and
cutting between drilled holes in
concrete and masonry.
MAINTENANCE
WARNING
To reduce the risk of injury,
always unplug your tool before performing
any maintenance. Never disassemble the tool
or try to do any rewiring on the tool's electrical
system. Contact a MILWAUKEE service facility
for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the gen-
eral condition of your tool. Inspect guards, switches,
tool cord set and extension cord for damage. Check
for loose screws, misalignment, binding of moving
parts, improper mounting, broken parts and any
other condition that may affect its safe operation. If
abnormal noise or vibration occurs, turn the tool off
immediately and have the problem corrected before
further use. Do not use a damaged tool. Tag damaged
tools "DO NOT USE" until repaired (see "Repairs").
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electrical
operation
Maintaining Hammer Chisels
Through normal use, the shank of the chisel can
"mushroom" over and cause the chisel to become
stuck inside the hammer. To prevent this from hap-
pening, periodically remove the chisel from the tool
and inspect the shank. If the shank starts to "mush-
room", have the chisel refurbished or replaced.
Brush Replacement
These MILWAUKEE hammers are will automatically
shut off when the brushes need to be replaced. Re-
turn your tool to the nearest MILWAUKEE service
facility for repairs.
Service Indicator Light
These MILWAUKEE Hammers feature a service
indicator light. When the red light turns on, the
tool is in need of servicing. Return your tool to the
nearest MILWAUKEE service facility for service.
NOTE: When the service light comes on, the tool
will continue to run for a few hours and then the
motor will shut off.
WARNING
To reduce the risk of injury,
electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid
to fl ow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your
tool since certain cleaning 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 detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
