Operation
6.
Check all fluid connections for leaks. Relieve the
fluid pressure before tightening connections.
7.
Install the spray tip and tip guard. Lock the gun
trigger safety. Install the spray tip according to the
instructions supplied with it.
8.
Adjust the spray pattern.
a.
Increase the pressure just until the spray from
the gun is completely atomized. Use the low-
est pressure needed to get the desired results.
This procedure reduces over–spray and fog-
ging, decreases the spray tip wear, and
extends the life of the sprayer.
b.
If more coverage is needed, use a larger tip
rather than increasing the pressure.
c.
Test the spray pattern. To adjust the pattern,
lock the gun trigger safety, loosen the retaining
nut. Position the tip guard horizontally for a
horizontal pattern or vertically for a vertical
pattern. Tighten the retaining nut.
Maintenance
Cleaning a Clogged Tip
WARNING
To reduce the risk of a serious injury, follow the
Pressure Relief Procedure on page 4 whenever
you are instructed to relieve the pressure.
To reduce the risk of a serious injury from acciden-
tally injecting fluid into the skin, follow these pre-
cautions.
Never operate the spray gun with the tip guard
removed.
Do not hold your hand, body, or a rag in front of
the spray tip when cleaning or checking a
clogged tip. Always point the gun toward the
ground or into a pail when checking to see if the
tip is clear.
Do not try to “blow back” paint; this is not an air
spray sprayer.
WARNING
1.
Clean the front of the tip frequently. First, relieve
the pressure.
2.
If the spray tip clogs, release the gun trigger, lock
the gun trigger safety, and rotate the handle (A) of
the RAC IV by 180
. See Fig. 5, which shows the
handle in the spraying position and the gun trigger
safety (B) in the locked position.
3.
Unlock the gun trigger safety. Trigger the gun into
a waste container. Lock the gun trigger safety
again.
4.
Return the handle to the original position, unlock
the gun trigger safety, and resume spraying.
5.
If the tip is still clogged, lock the gun trigger safety,
shut off and unplug the sprayer, and open the
pressure drain valve. Clean the spray tip as shown
in manual 307–848.
