Advice on Cleaning Spray Guns
When used with a cup, thinner or
suitable solvent should be syphoned
through the gun by inserting tube in
open container of that liquid. Move
trigger constantly to flush passageway
and clean tip of needle.
Ensure Adequate Ventilation.
When the gun is used with a pressure
fed container or gravity bucket, remove
the hose, turn the gun upside down and
pour thinners into the fluid opening whilst
moving the trigger constantly. This will
flush all passageways.
It is extremely poor practice to place an
entire gun in thinners. When this is done
the solvent dissolves the oil in the gland
packing and causes the gun to split.
It is good practice to place the nozzle
and fluid connection in thinners. Vessel
used should be shallow enough to
prevent thinner from reaching the
pickings.
