Before Operating This Equipment
The purpose of safety symbols is to attract your attention to possible hazard-
ous conditions. This manual uses a series of symbols and signal words which
are intended to convey the level of importance of the safety messages. The
progression of symbols is described below. Remember that safety messages by
themselves do not eliminate danger and are not a substitute for proper accident
prevention measures.

not avoided, WILL result in death or serious injury.
Safety Instructions For Pneumatic Tools
1. KEEP ALL SAFETY DEVICES IN
PLACE and in working order.
2. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of check-
ing to see that keys and adjusting
wrenches are removed from tool
before operation.
3. KEEP WORK AREA CLEAN.
Cluttered areas and benches invite
accidents.
4. DO NOT USE IN DANGEROUS
ENVIRONMENT. Do not use pneu-
matic tools in damp or wet loca-
tions, or where any flammable or
noxious fumes may exist. Keep
work area well lighted.
5. KEEP CHILDREN AND VISITORS
AWAY. All children and visitors
should be kept at a safe distance
from work area.
6. MAKE WORKSHOP CHILD
PROOF by locking your shop and
shutting off air valves.
7. DO NOT FORCE TOOL. It will do
the job better and safer at the rate
for which it was designed.
8. USE THE RIGHT TOOL. Do not
force tool or attachment to do a job
for which it was not designed.
9. DO NOT USE UNDER THE

10. USE PROPER AIR HOSE for the
tool. Make sure your air hose is in
good condition and is long enough to
reach your work without stretching.
11. WEAR PROPER APPAREL. Do not
wear loose clothing, gloves, neck-
ties, rings, bracelets, or other jew-
elry which may get caught in moving
parts. Non-slip footwear is recom-
mended. Wear a protective hair cov-
ering to contain long hair.
12. ALWAYS USE SAFETY GLASSES.
Also use a face or dust mask if cut-
ting operation is dusty. Everyday
eyeglasses only have impact resis-
tant lenses, they are NOT safety
glasses.
13. WEAR APPROVED HEARING
PROTECTION. Air escaping from
pneumatic tools can exceed safe
exposure limits and may cause
hearing damage with prolonged
exposure.
14. SECURE WORK. Use clamps or a
vise to hold work when practical. It is
safer than using your hand and frees
both hands to operate tool.
15. MAINTAIN TOOLS WITH CARE.
Keep tools lubricated and clean
for best and safest performance.
Follow instructions for lubricating
and changing accessories.
16. REDUCE THE RISK OF
UNINTENTIONAL STARTING. Do
not carry tool with hand on trig-
ger and always disconnect from air
when not in use.
17. DISCONNECT TOOLS before ser-
vicing and changing accessories.
18. DO NOT OVERREACH. Keep
proper footing/balance at all times.
19. USE THE RECOMMENDED
ACCESSORIES. Consult owner’s
manual for recommended acces-
sories. The use of improper acces-
sories may cause risk of injury.
20. CHECK FOR DAMAGED PARTS
BEFORE USING. Check for bind-
ing and alignment of parts, broken
parts, part mounting, loose bolts,
and any other conditions that may
affect machine operation. Repair or
replace damaged parts.
21. NEVER LEAVE UNATTENDED
TOOL CONNECTED TO AIR.
Disconnect the air hose and do not
leave tool until it is relieved of any
built up pressure.
22. NEVER ALLOW UNTRAINED
USERS TO USE THIS TOOL
WHILE UNSUPERVISED.
23. IF YOU ARE UNSURE OF THE
INTENDED OPERATION, STOP
USING TOOL. Seek formal training
or research books or magazines
that specialize in pneumatic tools.
24. BE AWARE OF HOSE LOCATION
WHEN USING PNEUMATIC
TOOLS. Hoses can easily become
a tripping hazard when laid across
the floor or spread out in a disorga-
nized fashion.

1. Fluid Control: Controls the volume of
material that travels through the fluid
tip.
2. Pattern Control: Adjusts the spray
pattern from a round pattern to a wide
fan.
3. Air Flow Control: Controls the fluid
pressure inside the spray gun (H7672
only).
4. Atomizing Cap: Controls the spray
pattern from vertical to horizontal.
5. Trigger: Two stage trigger. Stage
one only releases compressed air for
blowing off the work piece. Stage two
sprays material.
6. Regulator/Gauge: Regulates inlet
air pressure to the spray gun. It can
be attached directly to the gun for on-
the-spot air adjustments or directly
from the air source.
Note: DO NOT attach the regula-
tor to an unregulated air source that
exceeds 120 PSI.

Figure 4. Controls.
2. Screw the cup onto the top of the
body.
3. Attach the air hose to the spray gun
with a 1⁄4" NPS quick connect fitting
(not included).
4. Attach the spray gun to an air hose
regulated between 29 and 50 PSI.
Note: For the best results, use a hose
that will be dedicated for spray use
only. Do not use a hose that has been
used with an in-line oiler or other pos-
sible contaminant.
