Setup
1.
Install the GM3012 pump kit. See page 5.
NOTE: If desired, replace the 100 mesh filter element
already in the filter with the 30 mesh element, supplied
with the sprayer.
2.
Connect the hose and gun. See Fig 1. Screw a
minimum 50 ft. (15.2 m) main fluid hose (B) onto
the swivel (238). Connect a 3 ft. (0.9 m) whip hose
(C) between the fluid hose and the gun (A). Do not
use thread sealant, and Do not install the spray tip
yet!
WARNING
Be sure the fluid hoses are electrically conductive,
that the gun has a tip guard, and that each part is
rated for at least
3000 psi (210 bar) Maximum
Working Pressure. This is to reduce the risk of seri-
ous bodily injury caused by static sparking, fluid
injection or over-pressurization and rupture of the
hose or gun.
3.
Fill the packing nut/wet–cup. Pull the plastic cap
(5) up from the packing nut/wet–cup and fill the
cup 1/3 full with Graco Throat Seal Liquid (TSL).
Reinstall the cap. TSL helps lubricate and protect
the throat packings. Check the level of the TSL
regularly and fill as necessary.
4.
Flush the pump. See page 6.
5.
Prepare the paint or coating. For most paints:
remove any skin, stir to mix pigments, strain
through a fine nylon mesh bag to remove particles
that could clog the filter or spray tip. This is an im-
portant for trouble–free spraying.
6.
Two gun hookup (See Fig 1.) Remove the cap
(228) from the secondary hose outlet and attach a
hose and gun to the 1/4 npsm(m) nipple.
CAUTION
To avoid damaging the pressure control, which may
result in poor equipment performance and compo-
nent damage, follow these precautions.
1. Always use nylon spray hose at least 50 ft.
(15.2 m) long.
2. Never use a wire braid hose; it is too rigid to
act as a pulsation dampener.
3. Never install any shutoff device between the
filter and the main hose. See Fig 1.
4. Always use the main filter outlet for one gun
operation. Never plug this outlet.
