on page 2 for more detailed
grounding instructions.
1. Connect the hoses and gun to the sprayer.
Use
a 1/4 in. ID, 50 ft (15 m) long (minimum) main
hose (85). For more flexible gun movement, install
a 3/16 in. ID, 3 ft (0.9 m) hose (86) between the
main hose and the gun (87). Don’t use thread
sealant, and don’t install the spray tip yet!
2. Fill the packing nut/wet-cup (221)
1/3 full with
Throat Seal Liquid (TSL), supplied.
3.
Check the electrical service.
a.
Electrical requirements: 120 V
AC, 60 Hz,
15A (minimum).
b.
Use a grounded electrical outlet located at
least 20 ft (6 m) from the spray area.
c.
Do not remove the grounding prong of the
power supply cord, and do not use an
ungrounded adapter
.
d.
Extension cord specifications: 15A, 3 wires,
grounding type. Note that long lengths reduce
sprayer performance. A maximum extension
cord length of 200 ft (60 m) is recommended.
4. Flush the pump
to remove the oil left in to protect
pump parts after factory testing. See
Flushing
on
page 9.
5.
Prepare the paint.
Remove any paint skin. Stir
the paint thoroughly
. Strain the paint through a fine
nylon mesh bag to remove particles that could clog
the filter
