2
.
Professional sprayer
with 0.8mm spray
nozzle for spraying
latex and other thick
materials attached.
.
Viscosity test cup, which
enables you to test your paint
for thickness before painting.
.
Flexible extension
nozzle, which can be
bent at any angle,
making it easier to
paint horizontal or angled
surfaces.
.
0.6mm general purpose
spray nozzle.
.
Bottle of Lubricating Oil
.
Replacement atomiser
valve. Atomiser valves wear
with use, this is apparent
when the spray pattern
changes and atomisation is
incomplete. Then it is time
to change the atomiser valve.
.
1.5m (5’) Suction tube
for paint cans. For larger
jobs, paint can be fed
directly from a can using
the suction tube. To
secure tube onto can use
retainer clamp as provided. Hang
paint can on a rung with a wire hook
if a ladder is used.

ABOUT THE SG85.
The SG85 is a highly versatile
electric airless spray gun, it can be
used with several different spray
mediums including varnishes, wood
preservatives, enamel paint, oil
based paint and water based
paints. Airless spraying reduces the
mist associated with air spraying
and also reduces paint loss.
A number of applications can be
performed including spraying
fences, sheds, boats, furniture,
radiators, models, louvre doors etc.
IMPORTANT- SELECTING PAINT
Although a large number of paints
and materials can be sprayed,
some cannot. Please check
manufacturers recommendation
before purchasing paint.
CUPRINOL®This company’s
products clearly show which can be
sprayed and which are brush only.
If the can gives details of ‘Airless
Spraying’ it can be sprayed. If it
refers to brush application only it
cannot be sprayed.
IT CANNOT BE USED FOR
EXTERIOR TEXTURED WALL
PAINTS OR TEXTURED
COATINGS. USE OF THESE
MATERIALS WILL CAUSE
PREMATURE WEAR ON THE
PISTON AND WILL VOID YOUR
GUARANTEE.

PREPARATION
Surface preparation and paint
thinning are the two most important
areas to be concerned with to
obtain the best results from your
spray gun.
Ensure all surfaces are free from
dust, dirt and grease.
Masking is important to ensure you
do not spray those areas you wish
to remain untouched.
Ensure paint is thoroughly mixed.
THINNING
Thinning is particularly important
when spraying. Most paints are
supplied ready for brush application
and need to be sufficiently diluted
for spraying purposes.
sg82 amend p8.qxd 19/01/00 12:35 Page 4
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 recommendations 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 filter 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.
