INSTRUCTIONS.
Before use, read this instruction
sheet, the tool and dust extractor manuals, and all
labels on the bit, tool, and dust extractor. Failure to
follow the warnings and instructions may result in
serious injury. Save all warnings and instructions for
future reference.
• Use only with dust extractors with 'self-cleaning'
filters.
• Use the proper bit for the power tool. The bit
must properly fit the tool.
• Wear a dust mask or use an OSHA compliant
dust extraction solution
when working in dusty
situations. Dust particles can harm your lungs.
•
This product is suitable for collection of silica
dust when used in accordance with these in-
structions. To reduce the risk of health hazards
from other vapors or dust, do not vacuum car-
cinogenic, toxic or hazardous materials
such as
asbestos, arsenic, barium, beryllium, lead, pesticides
or other health endangered materials.
• Ensure unit is properly attached to power tool
before use.
•
WARNING
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated lum-
ber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopic particles.
• The unit is compliant with Table 1 of OSHA
Standard 29CRF 1926.1153 assuming (1) it is
used in accordance with MILWAUKEE instruc-
tions; (2) it is attached to a dust collector that
has a filter with 99% or greater efficiency and
a filter-cleaning mechanism. Please reference
https://www.osha.gov for further details on com-
pliance methods.
• The unit is compliant as an objective data
solution of OSHA
Standard 29CRF 1926.1153
when it used without a dust collector,
assuming it is used in accordance with
MILWAUKEE instructions. Please reference
https://www.osha.gov for further details on com-
pliance methods.
READ AND SAVE ALL
INSTRUCTIONS
FOR FUTURE REFERENCE.

OPERATION
With dust extractor:
1.
Before each use, check the plastic film for holes.
NOTICE!
Discard and replace the dust cap if holes
appear. The unit is no longer OSHA compliant
once the plastic film is punctured. Remove debris
from dust cap before each use.
NOTE:
Remove debris by wiping with a rag. If using
water, make sure the dust cap is dry before use.
2. Remove bit from hammer.
3. Compress the dust cap by pushing down on it.
Twist the spring rims together to lock.

4. Line up the dust cap to the hammer nose. Feed
bit through the unit and lock bit into place on the
hammer.
5. Attach the strap to the rotary hammer by stretching
it through the handle and threading beads through
the strap mounting tabs. Ensure a tight fit. Cut ex
-
cess strap at the next bead to prevent interference.
6. Remove the vacuum plug and attach the
Milwaukee Power Tool Adaptor (49-90-1957) or
similar size adaptor to the vacuum port. Connect
the extractor hose to the adaptor.
7. Turn the dust extractor to "automatic-cleaning"
mode.
8. Begin drilling.
NOTICE!
Bit may be hot after use.
Empty dust cap into a bucket placed on the ground
next to the drilling location after drilling each hole.
NOTE:
Use caution when drilling in water or wet
areas. If the bit gets wet, stop operation and let the
bit dry out thoroughly. Concrete must be properly
cured before drilling. Concrete dust will solidify in
the bit if wet.
9. To release unit, pull strap forward and release from
strap mounting tabs. Decompress the dust cap
and twist the spring rims to lock during storage.
10.
Use a HEPA-filtered vacuum to clean any re
-
sidual dust from the work area.
Without dust extractor:
1.
Before each use, check the plastic film for holes.
NOTICE!
Discard and replace the dust cap if holes
appear. The unit is no longer OSHA compliant
once the plastic film is punctured. Remove debris
from dust cap before each use.
NOTE:
Remove debris by wiping with a rag. If using
water, make sure the dust cap is dry before use.
