3. 

Personal safety

a. 

Stay alert, watch what you are doing and 

use common sense when operating this 

compressor.  Do not use this compressor 

while you are tired or under the influence 

of drugs, alcohol or medication.

  A moment 

of inattention while operating a compressor 

may result in serious personal injury.

b. 

Use personal protective equipment.  

Always wear ANSI-approved eye 

protection during setup and use.

c. 

Prevent unintentional starting.  Ensure the 

switch is in the off-position before connecting 

to power source or moving the compressor.

4. 

Compressor use and care

a. 

Do not use the compressor if the switch 

does not turn it on and off.

  Any compressor 

that cannot be controlled with the switch 

is dangerous and must be repaired.

b. 

Disconnect the plug from the power source 

before making any adjustments, changing 

accessories, or storing the compressor.

  

Such preventive safety measures reduce the 

risk of starting the compressor accidentally.

c. 

Store an idle compressor out of the reach 

of children and do not allow persons 

unfamiliar with the compressor or these 

instructions to operate it.

  A compressor is 

dangerous in the hands of untrained users.

d. 

Maintain the compressor.  Keep the 

compressor clean for better and safer 

performance.  Follow instructions for 

lubricating and changing accessories.  

Keep 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 the compressor’s 

operation.  If damaged, have the compressor 

repaired before use.

  Many accidents are 

caused by a poorly maintained compressor.

e. 

Use the compressor in accordance with 

these instructions, taking into account 

the working conditions and the work to 

be performed.

  Use of the compressor for 

operations different from those intended 

could result in a hazardous situation.

5. 

Service

a. 

Have your compressor serviced by a 

qualified repair person using only identical 

replacement parts.

  This will ensure that the 

safety of the compressor is maintained.
