General Repair Information

Pressure Relief Procedure

Read warnings, page 2.

1. Lock gun safety latch.
2. Turn ON/OFF switch to OFF.
3. Unplug power supply cord.
4. Unlock gun safety latch. Hold metal part of gun

firmly to grounded metal pail. Trigger gun to relieve

pressure.

5. Lock gun safety latch.
6. Open pressure drain valve. Leave pressure drain

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. Now clear

tip or hose obstruction.

CAUTION

To reduce risk of pressure control malfunction:

D

Use needle nose pliers to disconnect wire. Never

pull on wire, pull on connector.

D

Mate wire connectors properly. Center flat blade of

insulated male connector in female connector.

D

Route wires carefully to avoid interference with

other connections of pressure control. Do not pinch

wires between cover and control box.

1.

Keep all screws, nuts, washers, gaskets, and

electrical fittings

removed during repair proce-

dures. These parts are not normally provided with

replacement assemblies.

Read warning, page 2.

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 Guide,

pages 8 -- 12, for other possible solutions.

Read warnings, page 2.

CAUTION

Do not run sprayer dry for more than 30 seconds to

avoid damaging pump packings.

4.

Install motor shield before operation

of sprayer

and replace if damaged. Motor shield prevents

overheating, and protects operator from possible

electrical shock by touching terminals of capacitor.

It can also reduce risk of burns, fire or explosion;

see preceding
