Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. To

reduce the risk of an injury from accidental spray
from the gun, splashing fluid, or moving parts,
follow the 

Pressure Relief Procedure

 whenever

you:

D

are instructed to relieve the pressure,

D

stop spraying,

D

check or service any of the system equipment,

D

or install or clean the spray nozzle.

1.

Lock the gun trigger safety.

2.

Shut off the power supply to the pump and close
any bleed-type master air valves in the air supply.

3.

Unlock the gun trigger safety.

4.

Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun into the
pail to relieve pressure.

5.

Lock the gun trigger safety.

6.

Open the pump fluid drain valve (required in the
system), having a container ready to catch the
drainage.

7.

Leave the drain valve open until you are ready to
spray again.

If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, 

very slowly loosen the

tip guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Now clear
the tip or hose.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Proper electrical grounding is essential
to reduce the risk of fire or explosion
which can result in serious injury and
property damage. Also read 

FIRE OR

EXPLOSION HAZARD

 on page 3.

1.

Pump or Sprayer:

 as instructed in your separate

pump or sprayer manual.

2.

Air compressor or hydraulic power supply:

 accord-

ing to local code.

3.

Fluid hoses: 

use only grounded hoses with a

maximum of 500 feet (150 m) combined hose
length to ensure grounding continuity.

4.

Spray gun:

 obtain grounding through connection to

a properly grounded fluid hose and sprayer or
pump.

5.

Fluid supply container: 

according to local code.

6.

Object being sprayed: 

according to local code.

7.

All solvent pails used when flushing,

 according to

local code. Use only metal pails, which are con-
ductive. Do not place the pail on a non-conductive
surface, such as paper or cardboard, which inter-
rupts the grounding continuity.

8.

To maintain grounding continuity when flushing or
relieving pressure

, always hold a metal part of the

gun firmly to the side of a metal pail, then trigger
the gun.
