BASIC TECHNIQUES
Place the suction tube in the paint, switch ON and turn
up the pressure slightly.
When bubbles no longer appear, turn the prime valve
to SPRAY. Then trigger the gun to expel any solvent in
the hose. Once paint flows freely, turn the pump OFF.
Refit the spray tip
with the arrow pointing in the spray
direction
and switch ON
.
Test the spray pattern
on a piece
of cardboard, turning up the pressure just enough to totally
atomise the paint.
Paint the area in horizontal or vertical strokes,
each
overlapping its predecessor by about 25%.
For the best results,
always move the gun at a steady,
even pace parallel to the surface. Keep the gun at a
distance of about 300mm.
For most jobs,
point the gun
at right angles to the
surface.
In windy conditions, angle the
gun to spray into the wind and
cover the area with vertical
strokes.
To ensure even coverage at the
start and end of each stroke,
start the gun moving just
before you squeeze the
trigger and release the
trigger just before the gun
stops.
Paint corners and edges with
vertical strokes,
positioning
the gun so that the corner or
edge is roughly in the centre of
the spray fan.
If the spray tip should
become blocked, reverse the
tip
so that the arrow points
towards you and
spray into a
suitable metal container until
the paint flows freely
once
more. The tip can then be
returned to its normal spray
position.
Keep the equipment clean.
Even if you are taking only a
short break, clean it out
thoroughly. Regularly remove
the tip and seal for cleaning.
Remember that
in cold
weather paint will thicken
and greater pressure may be needed.
In warm or
hot
weather, paint will dry quicker.
If using a twopack paint
ALWAYS consult the manufacturer before use, as weather
conditions can drastically change the way it behaves.
Damaged hoses are potentially dangerous so handle
them with care
and coil them neatly, without kinks, for
storage.
Never push the equipment beyond its design
limits.
If it will not do what you want with reasonable ease
and speed, assume you have the wrong tool for the job.
Contact your local HSS Hire for advice. When not in use,
store the equipment somewhere clean, dry and safe
from
thieves.
Switch the unit OFF and release any pressure via the
spray gun before turning the prime valve to PRIME
and
engaging the gun’s trigger lock.
Remove the spray tip and
soak it in the appropriate solvent.
Place the suction tube into a container of a suitable
solvent and hold the bleed line over the paint container.
Turn the pressure to minimum then switch the unit ON
to
recapture the paint still in the system.
Once solvent starts
to flow out of the bleed line quickly transfer it to the
solvent container. Then simply clip the bleed line to the
suction tube and allow to circulate for a few minutes.
Next,
clean the spray gun and hose. Set the prime valve to
spray and ‘pump’ the remaining paint back into its can,
keeping the gun in contact with the container at all times.
Once the solvent appears at the nozzle, continue
pumping into the solvent container for a few minutes to
flush out any remaining paint.
That done,
set the prime valve to PRIME, remove the
suction tube from solvent, let the unit pump until nearly
dry, then switch OFF.
You should
now repeat the above procedure using fresh
solvent
before cleaning up the spray - tip with a soft brush
and refitting it.
If water was used as the solvent, pump some airless
corrosion check solution,
available from your local HSS Hire,
through the system. This will prevent corrosion of the
machine and the solidifying of paint during storage.
Collect everything together and give the unit a final
clean up ready for return,
to your local HSS Hire.
