•  Stay alert, watch what you are 
doing and use common sense 
when operating a power tool. Do 
not use tool while tired or under 
the influence of drugs, alcohol, or 
medication. A moment of inattention while operating power tools 
may result in serious personal injury.
•  DEPTH ADJUSTMENT:  To reduce risk of serious injury 
from accidental actuation when attempting to adjust depth, 
ALWAYS:
•  Disconnect air supply.
•  Avoid contact with trigger during adjustments.
 WARNING: Some dust created by power sanding, sawing, 
grinding, drilling, and other construction 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. 
 WARNING: ALWAYS USE SAFETY GLASSES. Everyday 
eyeglasses are NOT safety glasses. Also use face or dust mask 
if operation is dusty. ALWAYS WEAR CERTIFIED SAFETY 
EQUIPMENT:
•  ANSI Z87.1 eye protection (CAN/CSA/Z94.3),
•  ANSI S12.6 (S3.19) hearing protection,
•  NIOSH/OSHA/MSHA respiratory protection.
