Equipment Pressure

The HRO ST-3131 pump can develop 3500 P.S.I. (225 Bar) maximum working pressure at Never exceed this maximum pressure to the pump. Exceeding the maximum working pressure can result in serious equipment damage or rupture.

FIRE OR EXPLOSION WARNING

The flow of fluid through the inside of pump and hose can give occasion to static electricity by the high velocity, so be sure to ground every part of the spray equipment properly. Sparking can ignite fumes from solvents and fluid being sprayed, dust particles and other flammable substances, whether you are spraying indoors or outdoors, It can result in serious bodily injury or property damage.

Never plug in or unplug any power supply cords in the spray area where there is any chance of igniting fumes still in the air.

If you experience any static sparking or even a slight shock while using this equipment, stop spraying immediately and check the entire system for the grounding situation.

Do not use again until the problems have been identified and corrected.

PRESSURE RELIEF PROCEDURE

Always follow “PRESSURE RELIEF PROCEDURE’’ before servicing, cleaning or removal of the spray tip to prevent serious bodily injury, fluid injection, or splashing in the eyes.

1Engage the spray guns safety latch in “LOCK” position

2Shut off the power to the gas engine.

3Disengage the spray gun safety latch and aim the spray gun into the side of grounded metal pail, and trigger the

gun to relieve pressure.

1Re engage the spray gun safety latch in “LOCK” position.

2Open the drain valve to release pressure. Leave drain valve in open position during all service operations.

3Leave drain valve open until you are ready to spray again.

If you feel that the spray tip or hose is completely clogged or pressure has not been fully relieved after following the steps above, remove the tip retaining nut and release pressure gradually.

HOSE SAFETY

Because of the high pressure in the hoses, if the hose develops a leak, rupture, or other damage, High pressure fluid could penetrate the skin, causing serious bodily injury.

EQUIPMENT ALTERATION WARNING

Never alter any part of spray equipment or other accessories. Altered or modified. such as over-pressurizing, modifying parts, using incompatible chemicals and fluids including worn or damaged parts can result in malfunction causing serious bodily injury, fire, explosion or property damage. Always check all spray equipment regularly and repair or replace worn or damaged parts without delay.

Workman and assistant must always wear protective eyewear, gloves, clothing, and respirator as recommended by the material manufacturer.

•

Never use damaged hoses. Before using check the en- tire hose for cuts, leaks, abrasion, or a bulging cover. If any type of damage is noticed, replace the hose immedi- ately.

Spring guard : Hoses must have spring guard on both ends where easy to damage or wear than other parts. Tighten all fluid connections securely before use. High pressure fluid can dislodge a loose coupling.

Do not pull on hoses to move, only lift the hoses up to move them.

Do not exceed the hoses to temperatures above 180 de-

grees F. (82 degrees C.) or below –40 degrees F.	(-40
degrees C.)
Before using be sure to check a tag on it which	speci-
fies the maximum electrical resistance and	do not
exceed the recommended limits.

Ungrounded or poorly grounded hose can give way to serious system hazards or fire/explosion hazard.
