• 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.
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.
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.
