Brush Replacement - Milwaukee 5337-20 Manual Del Operador

NOTE: To make deeper holes, remove the core
bit, break and remove the core. 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.
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 firmly
established in the cut
(about 1/4" deep), re-
move the bit from the
cut.
3. Remove the bit from
the tool.
4. Install a standard fluted
bit, approximately 7/8"
in diameter, onto the
tool.
5. Drill a perpendicular
hole through the kerf of
the large hole.
• Depending on the lo-
cation of the work,
the hole should ei-
ther break through
the other side of the
hole/floor or extend
4"-5" past the end of
the workpiece (such
as into the dirt below
a concrete slab).
• If dust builds up in the
hole, vacuum it out
and continue drilling.
• If drilling through a
wall, the hole for dust
should be drilled on
the lowest part of the
large hole kerf as the
dust will fall there
when drilling and can
be evacuated more
easily.
6. Reinstall the core bit
and continue drilling.
Dust and debris will fall
through the hole and
optimize the cutting
ability of the bit.
7. For core bits, once
the maximum core bit
depth is drilled, the
core must be broken
and removed.
• Install a chisel bit.
• Place the chisel into
the hole kerf.
• Chisel down into the
kerf at several points
until the core is loose
or broken.
Cut approximately
1/4" deep with a
core bit.
Drill a hole
through the
work.
Dust and debris will fall
through the hole.

• Remove the core and vacuum/remove any re-
maining dust and debris.
• Install the core bit and continue the cut.
NOTE: If unable to drill a
hole in the kerf, pull back
on the bit with the hammer
running. This will remove
some of the dust and de-
bris from the cut. Repeat
this for every inch of drill-
ing. If necessary, vacuum
dust and debris from the
cut and surrounding area.
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
To reduce the risk of injury, always
WARNING
unplug the tool before performing
any maintenance. Never disassemble the tool.
Contact a MILWAUKEE service facility for ALL
repairs.
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.

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.
