 KGF/CM²

6.3 USING THE COMPRESSOR

Checking the charge status

Press the ON/OFF switch. (Position 20 in the overview) for 

approx. 3 seconds. The display is activated. The battery symbol 

shows the charging status (empty, 25 %, 50 %, 75 %,

You can set the target pressure with the buttons  

and 

(Position 21 and 19 in the overview), these can be read in the display 

‘TARGET’ (Position 17 in the overview).

Automatic/controlled lowering of the air pressure is not 

possible with this device.  

Connecting the air hose

Screw the end with the outer thread of the air hose (Position 24 in 

the overview) into the connection of the compressor (Position 6 in the 

overview).

Open the lock on the valve

Filling a tyre with the auto valve

If you want to fi ll a tyre with the auto valve (Schrader valve), you do 

not need any of the separate adapters. 

Using the adapter

Open the lock of the valve connection, Figure 2. Insert the right 

adapter for the application into the valve connection. Lock the valve 

connection, Figure 4. Place the adapter onto the fi lling connection of 

your bicycle or recreational article (ball, air toy etc.).

Bicycle valve adapter (for Dunlop and Sclaverand valves) 

(Position 27 in the overview):

Open the lock of the valve connection, Figure 2. Insert the right 

adapter for the application into the valve connection. Lock the valve 

connection, Figure 4. Place the adapter onto the fi lling connection of 

your bicycle or recreational article (ball, air toy etc.).

Bicycle valve adapter (for Dunlop and Sclaverand valves) 

(Position 27 in the overview):

For Sclaverand valves:

 Undo the knurled screw of the valve piston 

and push down briefl y once.

Screw the valve adapter, using the knurled crown, down onto the 

bicycle valve.

Place the valve connection of the air hose onto the bicycle valve 

adapter, like the auto valve, Figures 2 to 5. You can now start the 

compressor by pressing the ON/OFF switch and fi ll the bicycle tyres. On 

completion of the fi lling process, remove the air hose and the adapter 

from the valve.

For Sclaverand valves:

 Tighten the knurled screw of the valve piston 

again.

Adapter for balls (Position 26 in the overview):

Place the adapter for balls into the valve connection as shown in Fig-

ures 2 to 5. Insert the adapter into the valve of the ball. Now you can 

switch on the compressor and fi ll the ball. 

Universal adapter for recreational articles (Position 25 in the 

overview):

Place the universal adapter into the valve connection of the air hose 

as shown in Figures 2 to 5. Insert the universal adapter into the 

fi lling connection of your leisure equipment. Depending on version, it 

is possible that the universal adapter will need to be held fi rmly during 

the fi lling process.
Now you can switch on the compressor and start the fi lling process.
