  UNPACKING & ASSEMBLY 

 

Remove compressor from the carton: 

 

Wear protective gloves and cut the outer strapping with side cutters.  
Remove the staples with long nose pliers and open the top flaps. With assistance, carefully lift the compressor 
and place it on the work surface (See Fig.1). 

Carefully inspect the equipment for any missing items or damage incurred during transit. 

If anything is found to be missing or damaged contact your nearest Jefferson Dealer. 

We recommend that you store the packaging for the duration of the warranty period. If necessary, it will be 
easier to return the compressor to the service centre.

Fit the wheels (See Fig.2) and front feet, remove the transport bung from the oil filler hole and replace 
with the dipstick / breather supplied. Fit  the air filter and add oil to the pump, if necessary.

Confirm that the mains voltage corresponds with the voltage shown on the compressor's 
data / specification plate.
