4x4 TOUGH 150L User Manual - Before First Use

BEFORE FIRST USE

•  Turn the compressor on before connecting to the tyre in order to    

  reduce stress on the motor.

•  Use for a maximum 20 minutes then allow to cool for 20 minutes.

•  To prevent damage to the air hose fitting, remove the inflator from the  

  tyre before disconnecting the hose from the compressor.

•  The black power clip to a Negative ground point. Do not connect the  

  Black clip directly to the battery.

•  Test the connections by switching the compressor to “on”. Air will   

  begin to flow.   

•  Connect the air hose by screwing the brass inflator onto the tyre valve  

  stem. Only finger tighten the inflator. Do not use any tool as you may  

  damage the inflator or the valve stem.

•  Watch the gauge closely, switch the unit off or remove the inflator from  

  the tyre when the manufacturer’s recommended pressure has been achieved. 

•  We recommend that you use a second tyre pressure gauge to verify  

  your tyres are inflated to the proper pressure.

•  Stopping and restarting at high pressure can overload and blow the  

  in-line fuse. 

  At higher inflation pressures, start the unit and then attach to the valve  

  stem. If you stop the unit and need to resume inflation, remove the  

  inflator tip from the tyre valve, start the unit and reattach with the unit  

 running.

•  Allow the compressor to cool and place neatly in the carry bag with the  

  clips securely fastened to the loops on the carry bag. To prevent    

  damage to the unit during storage repack in the original colour box.

•  Store the unit in a dry location.

•  Remember to replace the valve cover on the stem.

OVERHEATING PROTECTION CIRCUIT

The unit is equipped with an automatic protection device. In the event the unit 

reaches an unsafe operating temperature, a protection circuit will cut power to 

prevent damage to the unit. If the protection circuit activates, immediately 

disconnect the unit from the power source and allow it to cool.

The unit will cool in approximately 15 minutes, depending on environmental 

conditions. The protection circuit will 

automatically

 reset itself when the 

temperature returns to a safe operating level. High altitude and certain air 

temperatures can negatively affect the unit’s performance.

HARD MOUNTING

This unit may be hard mounted in a dry location. Be sure to use proper 

size wiring for your application. When using this unit with an air tank, 

you must install a back-flow preventing device to prevent damage to 

the cylinder head air valve.
