Basic Maintenance 

6.1 Test for checking if there is air in the Ferret inflation system
 

Step 1. 
Install the Green Cap on 
the end of the Ferret Pipe.

Step 2.  
Slowly turn the Ferret 
Pump clockwise (+)  
to increase the pressure in 
the Ferret inflation system 
whilst watching the Ferret 
Pressure Gauge.

            IMPORTANT:  
 
If there is no air in the Ferret 
inflation system you should 
be able to achieve a pressure 
reading of 4 bar (60 psi) 
with no more than one full 
turn of the Ferret Pump. 

If there is air in the  
system remove it by  
following the instructions 
on the next page.
