Faithfull FAI SPRAY8HD, Manual

Safety pressure valve

 (Fig.7)

The safety pressure valve (2) will open when 

the pressure exceeds 2.5bar. It can also be 

opened manually to vent remaining pressure 

prior to opening.
To open the valve manually, pull up on the 

valve to release pressure. 

Spray operation

 (Fig.8)

The sprayer is operated by depressing the 

trigger (6).
For continuous spraying, pull the metal locking 

catch (6.1) forward and locate onto the plastic 

lug, locking the trigger in the open position.

Flow rate

 (Fig.9)

The force of the spray can be regulated using 

the flow adjustment dial (6.2) located on the  

trigger assembly.
Turn the dial anti-clockise for increased flow 

rate and clockwise to decrease the flow rate.

Variable spray pattern

 (Fig.10)

The spray pattern can be varied from a fine jet 

through to a wide fan by rotating the nozzle (4).

Note:

 Do not undo the nozzle too far as this 

will cause liquid to leak from the rear.

Note:

 If the nozzle continues to drip after 

the trigger handle has been shut off, there is 

probably air in the discharge system (nozzle, 

handle, tap and hose). Purge the system by 

turning the nozzle to jet and operating the 

trigger on and off in short bursts, until the 

liquid shuts off cleanly. Collect any liquid in a 

separate container to use later.

Telescopic lance

 (Fig.11)

Unscrew nut (5.1), pull lance out to desired 

length from 520 to 1150mm and retighten nut.
