Safety Information (continued)

AIR COMPRESSOR AND AIR TOOL SAFETY

1.  Risk of Bursting. Do not adjust the regulator to result in output 

pressure greater than the marked maximum pressure of this air 
tool.

2.  Ensure the hose is free of obstructions or snags. Entangled or 

snarled hoses can cause loss of balance or footing and may 
become damaged.

3.  Never leave a tool unattended with the air hose attached.
4.  Do not operate this tool if it does not contain a legible warning 

label.

5.  Do not continue to use a tool or hose that leaks air or does not 

function properly.

6.  Never direct a jet of compressed air toward people or animals.
7.  Protect your lungs. Wear a face or dust mask if the operation is 

dusty. 

WARNING:

 Some dust created by power sanding, sawing, 

grinding, drilling and other construction activities contains 
chemicals known to cause cancer, birth defects or other 
reproductive harm. Some examples of these chemicals are:

Lead from lead based paint, crystalline silica from bricks 
and cement and other masonry products, arsenic and 
chromium from chemically-treated lumber.

Your risk from those 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 dust masks that 
are specifically designed to filter out microscopic particles.

Important Warnings - Die Grinders 

Specifications

1.  Only use mounted grinding stones or mounted carbide burrs that meet ANSI standards, ISO standards or both. 
2.  Always use accessories with an RPM rating that meets or exceeds the tool RPM rating. 
3.  Never adjust the die grinder, adjust the collets or change the mounted stones or mounted burrs unless the air supply and air hose is 

disconnected from the die grinder.

4.  Only personnel trained in the correct methods to adjust collets and change mounted stones and mounted burrs should conduct these 

operations.

5.  Always ensure that you are aware of the direction of the sparks being created by the grinding operation and ensure that the sparks are 

not directed toward the operator or other persons in the area.

6.  Never use a die grinder close to any explosive or flammable materials or air conditioners.
7.  Only use mounted stones or carbide burrs that have the correct spindle diameter that matches the original collet size provided by the die 

grinder manufacturer.

8.  Particular care must be taken not to use metric size mounted stones and mounted burrs with die grinders that have imperial size collets, 

or use imperial mounted stones and mounted burrs with die grinders that have metric collets.
