Oracom MAX 695 General Repair Information, Pressure Relief Procedure, Electric Shock Hazard

CAUTION

To reduce risk of pressure control malfunction:

DUse needle nose pliers to disconnect a wire. Never pull on wire, pull on connector.

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

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

Tool List

1.Keep all screws, nuts, washers, gaskets, and electrical fittings removed during repair proce- dures. These parts are not normally provided with replacement assemblies.

WARNING

ELECTRIC SHOCK HAZARD

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, gaskets, screws and washers 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 4, for other possible solutions.

WARNING

EXPLOSION HAZARD

Motor and drive housing are very hot during operation and could burn skin if touched. Flammable materials spilled on

hot, bare motor could cause fire or explosion. Have motor shield in place during operation to reduce risk of burns, fire or explosion.

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 directs cooling air around motor to prevent overheating. It can also reduce risk of burns, fire or explosion; see preceding WARNING.

Pressure Relief Procedure

WARNING

INJECTION HAZARD

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 injec- tion, splashing fluid, or moving parts, follow Pres- sure Relief Procedure whenever you:

Dare instructed to relieve pressure,

Dstop spraying,

Dcheck or service any system equipment,

Dor install or clean spray tip.

1.Lock gun safety latch.

2.Turn ON/OFF switch to OFF.

3.Unplug power 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.
