Follow the manufacturers guide for
thinning inconjunction with a spray
gun. If in doubt please consult the
manufacturer of the paint. The
viscosity cup supplied will help you
determine the correct thickness of
the paint.
As some paints, wood
preservatives and other sprayable
materials contain particles and have
different qualities, please ensure
that when filling the paint container
on your SG85, the paint is filtered
through either a funnel with a filter
on it, or through nylon tights or
stockings. This will ensure no large
particles enter the paint container,
so preventing blockages and
providing you with trouble free
spraying. Ensure that a face mask,
gloves, goggles and ear protectors
are worn at all times when
spraying.
IDEAL VISCOSITY
Water based paints 35-45secs
Oil Based paints 15-25secs
Enamel paints 15-25secs
Wood preservatives no dilution
Primers 20-30secs
Varnishes 20-25secs
Aluminium paints 15-25secs
Wood stains no dilution
Latex Emulsions *10-20% dilution
Smooth Masonry Paint (non grit)
*5-10% dilution
* These paints cannot be measured in
the viscosity cup. To spray them,
remove the filter from the suction tube,
thin according to manufacturer’s recom-
mendations and strain to remove any
lumps or particles.

Dip the viscosity cup into the
material and fill up. Time how long it
takes the viscosity cup to empty (fig
1). Using the above chart as a
guide to determine if the material
requires further thinning, thin
accordingly.
OPERATION
Turn the gun upside down and
place a few drops of lubricating oil
in both the apertures on the
underside of the gun (see fig 2).
Momentarily trigger the spray gun
to disperse the oil around the piston
and cylinder, then firmly push the fil-
ter suction tube into the tapered
hole of the raised boss.
Fill the container with the paint,
when filling the paint container, filter
the paint through a piece of nylon
stocking or a funnel which
incorporates a filter to remove any
lumps or particles. DO NOT
OVERFILL. Screw the spray gun on
to the container tightly. Plug in the
unit and before you start spraying
the object, pull the trigger, aiming
the gun at a piece of cardboard or
newspaper until the paint comes
out.
