DANGER!
Potential hazard that will result in serious injury or loss of life.
•Keep bystanders, children and visitors away from the work area while
operating the compressor. Do not allow children to handle the compressor.
Distractions can affect the control of the compressor.
•Never point any nozzle or sprayer toward yourself, other people or animals.
Fast moving air may spread dust and debris which are harmful. Always
release air slowly when draining tank or depressurizing the compressor
system.
•Always shut OFF the compressor, remove the power plug from the electrical
outlet, and release all pressure from the air system, before attempting to
install, service, relocate, or perform any maintenance on the compressor.
•Never use plastic PVC pipe with the compressor. Failure to comply will result
in serious personal injury or death.
•Do not operate the compressor if the power cord or plug is damaged. Have
the cord or plug serviced at a qualified service centre.
•Follow all local electrical and safety codes.
Risk of burns: To prevent burns or other injuries, do not touch the
compressor while operating. Once stopped, allow it to cool before touching.
The compressor parts may be hot even if it is stopped.
•Motor, electrical equipment and control can produce an
electrical spark that will ignite a flammable gas or
vapour. Never use the compressor in a combustible
environment or in the presence of combustible materials,
such as flammable chemicals, adhesives, gasoline or
solvents, as the internal combustion produces hot exhaust
gases that may ignite flammable materials. Failure to
observe this warning can cause explosion and serious
personal injury or death.

•Risk of electric shock: Do not expose the compressor to rain or wet
conditions. Store it indoors. Make sure the power supply outlet and
grounding wire are grounded properly. Keep the power cord away from heat,
oil, sharp edges, moving parts, chemical spills, solvents and wet floors.
•Risk of bursting: Make sure the safety relief valve installed in the tank
complies with ASME code and has a setting not higher than maximum
working pressure. Never attempt to adjust the safety relief valve. Keep the
valve free from paint and other accumulations.
•Risk of fire or explosion: Always operate the compressor in a well-ventilated
area. Do not smoke while spraying paint or insecticides. Never spray
flammable liquids near ignition sources or in a confined area or the area
where spark or flame is present. Keep the compressor as far as possible
from the spraying area and all flammable materials.
• Never attempt to repair or modify the air tank, as doing so may damage the
tank, resulting in an explosion. Always replace the tank if it is worn, cracked,
or damaged.
•Risk of inhalation: Do not use the compressor to spray chemicals, as doing
so may affect your lungs by inhaling toxic fumes. Use a respirator in dusty
environment or when spraying paints.

accidental movement.
•Do not misuse the power cord. Never use the cord to carry the compressor.
Always use grip handle to move it. Remove the power plug from the power
supply outlet after use.
•Drain out the moisture from the air tank on a regular basis to prevent
corrosion of the tank. Inspect the tank periodically.
•Make sure the compressor vibrates normally during operation. If not, stop
the compressor and immediately find the cause of the vibration.
•Keep the compressor and the work area clean and well lit. A cluttered or
dirty workplace may lead to an accident. Floors should be kept clear.
•Protect the air hose and electric cord from damage and puncture. Inspect
them weekly for weak or worn spots, and replace them if necessary.
•Use safety glasses and ear protection.
Wear safety glasses with side shields when operating the
tool and verify that others in the work area are also wearing
safety glasses. Safety glasses must conform to American
National Standards Institute (ANSI Z87.1) requirements and
must provide protection from flying particles from the front
