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.
WARNING: Always use eye protection. All users and bystanders
must wear eye protection that conforms to ANSI Z87.1.
WARNING: When not in use, place grinder on a stable
surface where it will not move inadvertantly, roll or cause a
tripping or falling hazard. The grinder may stand upright on the
battery pack but may be easily knocked over. Serious personal injury
may result.
WARNING: The grinding wheel or accessory may loosen
during coast-down of the tool when shut off. If grinding wheel or
accessory loosens, it may dismount from the machine and may cause
serious personal injury.
CAUTION: To reduce the risk of personal injury, use extra care
when working into a corner or edge because a sudden, sharp
movement of the tool may be experienced when the wheel or other
accessory contacts a secondary surface or a surface edge.
• The label on your tool may include the following symbols. The
symbols and their definitions are as follows:
V ..................... volts
sfpm................ surface feet per
minute
min .................. minutes
or DC ..... direct current
................... Class I Construction
(grounded)
or AC/DC .. alternating or direct
current
.../min ............. per minute
BPM ............... beats per minute
IPM ................. impacts per minute
or AC .......... alternating current
• 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 smaller the gauge number,
the heavier the cord.
7
Hz .......... hertz
SPM ....... strokes per minute
A ............ amperes
W ........... watts
.......... Class II Construction
(double insulated)
RPM....... revolutions per
minute
no .......... no load speed
n............. rated speed
