WARNING
shroud, the angle grinder, the cup wheel, and the dust extractor
(vacuum cleaner) before use. Failure to heed these warnings may result in personal
injury and property damage.
SPECIAL SAFETY INSTRUCTIONS FOR SURFACE GRINDING
DUST SHROUD
The shroud must be securely attached to the angle grinder and positioned for
maximum safety, so the least amount of the wheel is exposed towards the operator.
The shroud is designed to collect dust in conjunction with a dust extractor and help
protect the operator from accidental contact with the wheel.
Only use dry diamond surface cup wheels with this surface grinding shroud. The
surface grinding shroud is not intended to be used with standard grinding, cut-off, cup
wheels or wire brushes.
Do not use accessories that require liquid coolants. Using water or other liquid
coolants may result in electrocution or shock.
DO NOT use wire brushes with this surface grinding shroud.
DO NOT use abrasive wheels.
DO NOT grind or cut metal with a diamond cup wheel. Fragments could loosen and
fly apart causing injuries and damage.
ALWAYS use with a dust extractor.
Wear eye, dust and ear protection. Always use side handle.
When not in use, place the grinder on a stable surface where it will not move
inadvertently, roll or cause a tripping or falling hazard. Serious personal injury may
result.
INTENDED USE
The dust shroud has been designed for extraction of dust created during grinding,
–
leveling, and polishing of concrete surfaces in conjunction with a suitable dust
extractor / vacuum cleaner (sold separately).

CONNECTING TO DUST EXTRACTOR (FIG. 4)
NOTE: Read the OSHA regulation on silica
Fig. 4
dust and the related OSHA Silica Table 1
to understand the requirements needed
to reduce exposure to silica dust at the
worksite. Specific rules apply to the drilling,
demolition, cutting and grinding materials
that contain silica. According to OSHA Silica
Table 1, when dry cutting or dry surface
grinding concrete type materials using
hand held grinders, the dust extractor (dust
collector) being used must provide 25 CFM
(cubic feet per minute) or greater air flow
Ø1-1/4"
per inch of wheel diameter. For example,
5" grinding wheel requires a dust extractor
with a rating of at least 125 CFM.
All OSHA requirements can be found at OSHA website: www.osha.gov
Always check OSHA website for the latest regulations.
This dust shroud MUST BE used with a dust extractor suitable for
WARNING
concrete/masonry dust collection. ALWAYS wear certified safety face
or dust mask.
The dust extractor port of the shroud is designed to connect to Ø1-1/4"
hoses or adapters.
Connect a suitable dust extractor hose to the dust extractor port. Use an adapter
(supplied) if needed. Make sure the connection is tight and secure.
OPERATING INSTRUCTIONS
The angle grinder should ALWAYS be used with a dust extractor vacuum designed for
dust removal.
