Inflating A Tyre

1.  Connect the air hose to the compressor.

2.  Connect the battery clamps 

to a running vehicle battery in 

the correct order.

3.  Screw the tyre chuck of the air 

hose onto the valve stem of 

the tyre to be inflated.

WARNING! 

ENSURE THAT THE TYRE CHUCK IS 

SECURELY ATTACHED. FAILURE TO FOLLOW THIS 

INSTRUCTION MAY CAUSE THE HOSE TO BLOW 

OUT AND WHIP ABOUT.

4.  Switch the air compressor on 

and allow the tyre to inflate. 

5.  Once the desired pressure has been reached, switch off the air 

compressor. Check if the desired inflation pressure has been 

reached. Repeat step 5 as necessary until the tyre is fully inflated.

Note: 

The air flow in the hose will increase the pressure reading 

shown on the gauge. Turning the compressor off may cause the 

reading to drop slightly, but this will provide an accurate reading of the 

pressure in the tyre. 

6.  Press the button on the back 

of the pressure gauge to 

release excess air if the tyre is 

over-inflated.

7.  Turn off the unit and unscrew the tyre chuck once the tyre is 

suitably inflated.

Inflating Other Objects.

1.  Connect the air hose to 

the compressor and the 

appropriate inflation nozzle to 

the tyre chuck.

2.  Connect the battery clamps 

to a running vehicle battery in 

the correct order.

3.  Insert the inflation nozzle into 

the air inlet on the object to be 

inflated.

4.  Whilst maintaining a firm grip on the air hose, switch the air 

compressor on and allow the object to inflate.

5.  Turn off the unit and remove the nozzle from the object once the 

object is fully inflated. 

WARNING! 

THE INFLATION HOSE & NOZZLE MAY 

GET HOT DURING USE IF THE AIR COMPRESSOR IS 

USED FOR LONGER THAN 5 MINUTES. SWITCH OFF 

THE AIR COMPRESSOR AND ALLOW THE HOSE & 

NOZZLE TO COOL BEFORE HANDLING.
