System pressure must be manually relieved to 
prevent system from starting or spraying 
accidentally. Fluid under high pressure can be 
injected through skin and cause serious injury. 
To reduce risk of injury from injection, splashing 
fluid, or moving parts, follow Pressure Relief 
Procedure whenever you:

•

are instructed to relieve pressure

•

stop spraying

•

check or service any system equipment

•

install or clean spray tip

1. Turn pressure control knob to zero.

2. Turn ON/OFF switch to OFF.

3. Unplug power supply cord.

4. Hold metal part of gun firmly to grounded 

metal pail. Trigger gun to relieve pressure.

5. Lock gun safety latch.

6. Open prime valve. Leave prime valve open 

until ready to spray again.

If suspected that spray tip or hose is 
completely clogged, or that pressure has 
not been fully relieved after following steps 
above, VERY SLOWLY loosen tip guard 
retaining nut or hose end coupling to 
relieve pressure gradually, then loosen 
completely. Then clear tip or hose 
obstruction.

1. Keep all screws, nuts, washers, gaskets, 

and electrical fittings removed during repair 
procedures. These parts are not normally 
provided with replacement assemblies.

To reduce risk of serious injury, including 
electric shock, do not touch moving or electrical 
parts with fingers or tools while testing repair. 
Shut off and unplug sprayer when inspection is 
complete. Install all covers, guards, gaskets, 
screws, washers and shroud before operating 
sprayer.

2. Test repair after problem is corrected.

3. If sprayer does not operate properly, review 

repair procedure to verify procedure was 
done correctly. If necessary, see 
Troubleshooting, page 11, for other 
possible solutions.

To reduce risk of pressure control malfunction:

•

Use needle-nose pliers to disconnect wire. 
Never pull on wire, pull on connector.

•

Mate wire connectors properly. Center flat 
blade of insulated male connector in 
female connector.

•

Route wires carefully to avoid interference 
with other connections of pressure control. 
Do not pinch wires between cover and 
control box.
