3. PAINT PREPARATION
The HVLP2002 spray gun set is a high volume, low pressure system intended primarily for the spraying of paints used for interior decorating
including water based paints, oil based paints, laquers and stains. It is not suitable for spraying solvent based paints such as those used in the
car refinishing trade. The all-in-one unit consists of a base station which houses the integral air supply unit and provides convenient stowage
for the spray gun plus a storage pocket. The spray gun has a plastic body, which resists corrosion and has a low affinity for paint making the unit
easy to clean. It also has an adjustable spray pattern and air flow control.

3.1.
Checking paint viscosity.
As most paints are made for brush or roller action it will normally be necessary to thin the paint to achieve proper atomization and
good coverage. Use the viscosity cup provided to check the viscosity of the paint prior to thinning (see fig.2). Dip the cup into the
paint to completely fill it and then time how long it takes for the paint to flow out again. If the paint is the correct viscosity the flow time
will be between 8 and 20 seconds. If the flow time is more than 20 seconds the paint is too thick. Thin the paint slightly and retest until
the flow time is within the limits stated. If the flow time is less than eight seconds the paint is too thin.
3.2.
Paint condition.
Any debris in the paint will clog the gun which will require a complete strip down and clean before the gun will function again properly.
This is particularly important when using paint that has previously been opened. The paint should be thoroughly mixed and free from skin
and lumps. If necessary strain the paint through a 60 mesh paint strainer, or a piece of cheesecloth or an old nylon stocking to ensure a
smooth finish. The paint should be strained into a clean container and if any paint is left over it should be stored in a clean container.
7
DO NOT mix or thin paint in an area where there may be functioning appliances producing a naked flame or electrical sparking. This
includes equipment that is electric motor powered.
7
DO NOT switch on the HVLP2002 when paint is being mixed or thinned.
3
Ensure that any vapours have dispersed before switching on the HVLP2002.
3
Tightly recap all containers immediately after thinning or mixing paint and store away from the spraying area.
7
DO NOT spray where there are any sources of ignition such as an open fire, cigarettes, cigars or pipes, sparks, glowing wires or hot
surfaces or naked lighting.
3
Ensure that the air hose is firmly connected to the unit and the gun to avoid the possibility of any spilt material being drawn into the unit.

fig. 4
4.1.
Remove the unit from the packaging and uncoil the power cable from the storage flange at the back
of the unit. Do not plug the unit in yet.
4.2.
Remove the spray gun from the unit and set the air cap to give the required spray pattern. Do this
by loosening the air cap locking ring as indicated in fig.4 and rotating the air cap to give the
required spray pattern as shown in fig.5. Retighten the locking ring.
4.3.
Unscrew the paint container. Fill container with paint (see Section 3 regarding paint preparation).
Refit the paint container to the gun and tighten. Place the gun back in the main unit.
4.4.
Lay out the air hose and connect one end to the back of the unit using a push and twist action
(see fig.3). Connect the other end of the hose to the gun as shown in fig.4.
4.5.
Plug the unit into the mains and switch on. You are now ready to spray.
