STARTUP PROCEDURE
Whenever the pump is to be used, it must be prepared for the type
of paint to be used. This requires the unit to be flushed out with an
appropriate solvent (water for latex, mineral spirits for oil base, etc.).
Incorrect flushing can cause gumming of the valves and priming
problems.
PRIME VALVE OPERATION:
1) DC-1600, DC-2000, DC-3100, DC-7700: Valve turns left or right.
PRIME position is when the valve is turned counterclockwise (pulled
out), and spray is when the valve is turned clockwise (seated in).
UNIT PRIMING AND FLUSHING:
1) Check that all hose, gun handle and tip connections are tight.
2) Place trigger lock in “LOCK” position. Plug unit into correct power
source.
3) Place prime valve into open or “PRIME” position.
4) Turn pressure control to minimum. Turn ON unit.
5) Place suction into container of correct solvent. Slowly, turn up the
pressure control into the prime zone. Motor will begin to run, watch
for flow from return tube.
6) Let pump prime for 20-30 seconds. Close prime valve. Unit will build
up a low pressure and cut out.
NOTE: Always turn down pressure control before changing
position of the prime valve. This reduces shock loading of the
pump and possible damage.
7) Turn zip tip to halfway position and remove from gun (see page 9).
Turn up pressure about 1/6 turn. This gives a good low pressure for
flushing and cleaning.
8) Aim gun into empty metal pail, holding gun body against pail edge to
ground gun for safety. Open trigger, and allow solvent to flow for one
minute.
9) Release and lock trigger (read static safety). Turn pressure control
to minimum and open prime valve to release pressure.
10) Unit is now flushed out.
PRIMING UNIT IN PAINT:
Follow same procedure as steps 1-7 of “Priming and Flushing”, but
instead using paint. Then continue with the remaining steps as outlined
below.
11) Remove tip from gun. Unlock trigger. Aim gun into solvent pail and
hold trigger open until solvent flow changes to paint. Release and
lock trigger. Re-install tip.
12) Turn up pressure approximately 1/2 to 3/4 turn from minimum
setting.
13) This about 2000 psi, which is a normal spraying pressure for many
medium thickness products. As the pressure you have set is
reached, the motor will slow down and cut out.
14) The motor will run when the gun is open. Motor on-off cycles is in
relation to both the size of the tip, and the pressure you have set.
Test spray pattern per chart below, and adjust pressure accordingly.
Figure 8. - Spray pattern examples.
NOTE
TO TURN UNIT OFF:
Always reduce pressure, turn prime valve to prime, trigger gun to
release pressure build up in hose, and turn motor off.
