HOSES
Tighten all fluid connections securely before each use.
High pressure fluid can dislodge a loose coupling or
allow high pressure spray to be emitted from the coup-
ling and result in an injection injury or serious bodily
injury.
WARNINGS continued
PRESSURE RELIEF PROCEDURE
To avoid possible serious body injury, always follow this procedure whenever the sprayer is shut off,
when checking it, when installing, changing or cleaning tips and whenever you stop spraying or when you
are instructed to relieve the pressure.
Ground the sprayer & other components in the system
to reduce the risk of static sparking, fire or explosion
which can result in serious bodily injury and property
damage. For detailed instructions on how to ground,
check your local electrical code.
ALWAYS ensure switch is in OFF position before
plugging unit in.
GROUNDING
NEVER use a damaged hose, which can result in
hose failure or rupture and cause an injection injury or
other serious bodily injury or property damage. Before
each use, check entire hose for cuts, leaks, abrasion
or bulging of cover, or damage or movement of coup-
lings. If any of these conditions exist, replace the hose
immediately. Never use tape or any device to try to
mend the hose as it cannot contain the high pressure
fluid. NEVER ATTEMPT TO RECOUPLE THE HOSE.
High pressure hose is not recoupleable.
Use only hose having a spring guard. The spring
guard helps protect the hose from kinks or other
damage which could result in hose rupture and
cause an injection injury.
2. Air Hoses; use only grounded hoses.
3. Fluid hose: use only grounded hoses.
4. Spray gun or dispensing valve; grounding is ob-
tained through connection to a properly grounded fluid
hose and pump.
5. Object being sprayed; according to your local code.
6. All solvent pails used when flushing.
Once each week, check electrical resistance of hose
(when using multiple hose assemblies, check overall
resistance.) Overall (end to end) resistance of
unpressurized hose must not exceed 29 megohms
(max.) for any coupled length or combination of hose
lengths. If hose exceeds these limits, replace it imme-
diately.
Never exceed 500 ft. (150 m) overall combined hose
length to assure electrical continuity.
1. Engage gun safety latch. Refer to separate
instruction manual provided with your gun on its
safety features and how to engage safety latch.
4. Turn Prime/pressure relief valve (PR
Valve) to the open (priming) position to
relieve residual fluid pressure.
There will
be a wider gap between valve handle
and cam body when in open position.
Note: When in closed position there is only a very
slight gap.
Note: The valve handle can move both
CCW & CW and can face different direc
tions.
2. Turn unit off and unplug from electrical outlet.
3. Disengage gun safety latch and trigger gun to
relieve residual fluid pressure.
Hold metal part of the gun in
contact with grounded metal pail.
USE MINIMUM PRESSURE !
5. Re-engage gun safety latch and
close prime/pressure relief valve.
Always ground all of these components.
1. Sprayer: plug the power supply cord, or extension
cord, each equipped with an undamaged three-prong
plug, into a properly grounded outlet. DO NOT USE AN
ADAPTER.
Use only a 3 wire extension cord that has a 3 blade
grounding plug, and a 3 slot receptacle that will accept
the plug on the product. Make sure your extension cord
is in good condition. When using an extension cord, be
sure to use one heavy enough to carry the current your
product will draw. (Note: The table on the top of the
next page shows the correct size to use depending on
cord length and name plate ampere rating. If in doubt,
use the next heavier gauge. The smaller the gauge num-
ber, the heavier the cord.
If the SPRAY TIP OR HOSE IS CLOGGED, follow Step 1 through 5 above. Expect paint splashing into the
bucket while relieving pressure during Step 4. If you suspect that pressure hasn't been relieved due to
damaged prime/pressure relief valve or other reason, engage gun safety latch and take your unit to
an authorized Airlessco Service Center.
