Instructions for Use –

Extend the pump plunger (

no. 20

) to its maximum length.

Attach the compressed air connection sleeve (no. 30, 1/4” connector) on to

the compressed air coupling for approximately 3 – 5 seconds, in order to

build up pressure in the bottle.

Slowly turn the nozzle to adjust spray pattern from fine mist to jet.

If liquid drops out of the nozzle on completion of spraying, spray for  approx.

2 – 3 seconds to release the trapped compressed air.
