activities contains chemicals known to the State
of California to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
•
lead from lead-based paints,
•
crystalline silica from bricks and cement and other
masonry products, and
•
arsenic and chromium from chemically-
treated lumber.
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.
•
Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing
dust to get into your mouth, eyes, or lay on the skin may
promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/
or disperse dust, which may cause serious and
permanent respiratory or other injury. Always use
NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles
away from face and body.
WARNING: Always wear proper personal hearing
protection that conforms to ANSI S12.6 (S3.19)
during use. Under some conditions and duration
of use, noise from this product may contribute to
hearing loss.
CAUTION: When not in use, place tool on its side
on a stable surface where it will not cause a
tripping or falling hazard. Some tools with large
battery packs will stand upright on the battery pack
but may be easily knocked over.
Air vents often cover moving parts and should be
•
avoided. Loose clothes, jewelry or long hair can be
caught in moving parts.

An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than 18
gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using
more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier the cord.

INTENDED USE
Your concrete surface grinding shroud has been designed
for dust removal of the following: grinding, leveling and
polishing concrete surfaces. It can remove dust when
removing surface paint, epoxy and glue. Using the
appropriate grinder, diamond grinding wheel and dust
extractor vacuum it can be used to remove the vast majority
of static and airborne dust which without the use of the
surface grinding shroud could otherwise contaminate the
working environment or pose an increased health risk to the
operator and those in close proximity. This concrete surface
grinder should ALWAYS be used with a dust extractor
vacuum designed for concrete dust removal.
