Installation/Operation
Care of the Spray Tip and Tip Guard
WARNING
INJECTION HAZARD
To reduce the risk of injection or
splashing in the eyes or on the skin:
D Do not place a hand, body or rag in front of the
spray tip when cleaning or checking a clogged
tip. Point the gun toward the ground or into a
waste container when checking to see if the
spray tip is cleared.
D Do not try to “blow back” paint; this is not an air
spray gun.
D Do not wipe fluid buildup off the gun or spray tip
until pressure is relieved. Follow the Pressure
Relief Procedure on page 7 whenever you
are instructed to relieve the pressure.
Cleaning during the day
1. Relieve the pressure.
2. Clean the front of the tip frequently during the day
to help reduce fluid buildup. Also clean the tip and
tip guard at the end of each work day. Use a
solvent-soaked brush to clean the spray tip.
If the spray tip clogs while spraying
1. Stop spraying immediately.
2. Lock the gun trigger safety. Rotate the RAC IV tip
handle back 180_. See Fig. 4.
3. Unlock the gun trigger safety. Trigger the gun into
a pail or onto the ground to remove the clog.
4. Lock the gun trigger safety. Rotate the tip handle
to the spraying position. See Fig. 4.
5. If the tip is still clogged, engage the gun trigger
safety, shut off the sprayer and disconnect the
power source, and open the fluid drain valve to
relieve pressure. Clean the spray tip as shown in
manual 307991, supplied with the RAC IV.
CAUTION
Do not soak the entire gun in solvent. Prolonged
exposure to solvent can ruin the packings.
