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

time rather than attempting too large an area.

unplug the tool before performing
any maintenance. Never disassemble the tool.

Maintaining Tools
Keep your tool 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 condi-
tion that may affect the tool operation. Return the tool
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the
tool to a MILWAUKEE service facility for inspection.
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.

shut off when the brushes need to be replaced. Re
-
turn your tool to the nearest
MILWAUKEE service
facility for repairs.

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 personal in-

never immerse your tool in liquid or allow a liquid
to flow inside it.
Cleaning
Clean dust and debris from any vents. Keep tool
