Work Area Safety
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate your Air Compressor in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Air Compressor motors produce sparks which may ignite
the dust or fumes.
3. Keep children and bystanders away from an operating Air Compressor.
Electrical Safety
1. Air Compressor plugs must match the outlet. Never modify the plug in any way. Do not use
any adapter plugs with grounded Air Compressors. Standard plugs and matching outlets will
reduce the risk of electric shock.
2. Do not expose your Air Compressor to rain or wet conditions. Water entering your Air
Compressor will increase the risk of electric shock.
3. Do not abuse the cord. Never use the cord for unplugging your Air Compressor. Keep the
cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase
the risk of electric shock.
Personal Safety
1. Stay alert, watch what you are doing and use common sense when operating your Air
Compressor. Do not use your Air Compressor while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattentiveness while operating your Air
Compressor may result in serious personal injury.
2. Use protective safety equipment. Always wear ANSI-approved eye protection during setup
and use.
3. Prevent unintentional starting. Ensure the switch is in the OFF position before connecting to
power source or moving your Air Compressor.
Air Compressor Use and Care
1. Do not use your Air Compressor if the switch does not turn ON and OFF. An Air
Compressor that cannot be controlled with the switch is dangerous and must be repaired.
2. Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing your Air Compressor. This preventive safety measure reduces the risk
of starting your Air Compressor accidentally.
3. Store your Air Compressor out of the reach of children and do not allow people unfamiliar
with your Air Compressor or these instructions to operate it. An Air Compressor is
dangerous in the hands of untrained users.

4. Maintain your Air Compressor. Keep your Air Compressor clean for maximum performance.
Follow the instructions for lubricating and changing accessories. Keep your Air Compressor
dry, clean and free from oil and grease. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect your Air Compressor's operation. If
damaged, have your Air Compressor repaired professionally before use. Many accidents are
caused by a poorly maintained Air Compressor.
5. Use your Air Compressor in accordance with these instructions, taking into account the
working conditions and the work to be performed. Use of your Air Compressor for
operations different from those intended could result in a hazardous situation.
Service
Have your Air Compressor serviced by a qualified professional repair person using only identical
replacement parts. This will ensure that the safety of your Air Compressor is maintained.
