Information
(Cont.)
●
Paints and solvents containing
HALOGENATED HYDROCARBONS can
react explosively with aluminum. Do
not use halogenated hydrocarbons
with this equipment. Consult the
paint or solvent product label or
Material Safety Data Sheets (MSDS)
to help determine if it contains
halogenated hydrocarbons.
●
Do not use fuels to clean this
equipment.
●
Keep spraying area well ventilated.
Keep doors and windows open.
●
Remove all ignition sources (i.e.
Static electricity, pilot lights,
cigarettes and electrical arcing).
●
Airless spraying can cause static
electricity. Always ground the
pump and spraying surface.
●
Do not use solvents containing
halogenated hydrocarbons.
Keep hose away
from sharp objects.
Bursting hoses may cause injury.
Examine hoses regularly and replace if
damaged.
●
Check hoses for weak or worn
condition before each use, making
certain that all connections are
secure.
Pre-Operation

factory tested in an oil solution which
was left in the pump. Before using oil-
based paint, flush with mineral spirits
only.Before using water-based paint
flush with mineral spirits, followed by
soapy water, then a clean water flush.
2. CHANGING COLORS: Flush with a
compatible solvent such as mineral

water, then mineral spirits.
4. CHANGING FROM OIL-BASED TO
WATER-BASED PAINT: Flush with
mineral spirits, followed by soapy
water, then a clean water flush.
5. STORAGE: Always relieve pressure
(See pressure relief procedure on
page 3) prior to storage or when
machine is unattended. Follow the
storage procedure based on the kind of
paint you used:
●
Oil-based paint: Flush with mineral
spirits.
●
Water-based paint: Flush with
water, then mineral spirits. Leave
the pump, hose and gun filled with
mineral spirits.
●
For longer term storage use a 50/50
mixture of mineral spirits and motor
oil. Always ensure that there is no
pressure in the unit, and close the
prime/pressure relief valve for
storage.
Never leave pump
unattended while it
is under pressure!
6. START UP AFTER STORAGE: Before
using water-base paint, flush with
soapy water and then a clean water
flush. Before using oil-based paint,
flush out the mineral spirits with
the material to be sprayed.
