 JobSmart 4 Gallon Air Compressor Assembly & Operating Instructions 

5

Disconnect the tool from power source before making any adjustments, storing, servicing, or 
changing accessories. This will reduce the risk of starting the tool accidentally. 
Do not force tool. Use the correct tool for your application. The correct tool will do the job better and 
safer at the rate for which it was designed. 
 
Do not use the tool if the switch does not turn it on and off. Any tool that cannot be controlled with the 
switch is dangerous and must be repaired. 
 
Check for damage. Check your tool regularly. If part of the tool is damaged it should be carefully inspected 
to make sure that it can perform its' intended function correctly. If in doubt, the part should be repaired. 
Refer all servicing to a qualified technician. Consult your dealer for advice. 
 
Keep away from flammables. Do not attempt to operate this tool near flammable materials or 
combustibles. Failure to comply may cause serious injury or death. 
 
Store idle tools out of the reach of children and untrained persons. Tools may be dangerous in the 
hands of untrained users. 
 
Maintain tools with care. Keep tools sharp and clean. Properly maintained tools, with sharp cutting edges, 
are less likely to bind and are easier to control. 
 
Never exceed the pressure rating of any component in system. 
 
Protect material and air lines from damage or puncture. Keep hose and power cable away from 
sharp objects, moisture, chemicals, oil, etc.  
 
Check condition of hoses before each use. Do not use a damaged hose. If hose is damaged, replace 
immediately. 
 
Read, understand and comply with all warning labels on unit. 
 
Drain tank of moisture after each use. If Compressor is not to be used for extended periods of time, leave 
tank drain valve open to allow moisture to completely drain from tank. 
 
Do not tamper with Safety Valve. The Safety Valve is factory set for your model air compressor. Any user 
adjustments to Safety Valve will automatically void warranty. 
 
Air compressors get hot while in operation. NEVER touch the motor, discharge tubing or compressor 
pump while in operation. 
 
The Compressor operates automatically while the motor is turned on. 
 
Compressed air from the unit may contain carbon monoxide. Air produced is not suitable for breathing purposes. 
 
Always use a respirator when spraying paint or chemicals. 
 
The air pressure switch is set at the factory for optimum performance of your equipment. Never 
attempt to bypass or remove this switch as serious damage to equipment or personal injury could result 
from excessive air pressure.
