Setup

Read, understand, and follow all warnings before starting or operating this sprayer.

Required tools: Adjustable wrench

1. Connecting the hoses:

The siphon hose and bleed line hose have factory installed

PTFE tape on the male end o the hoses. Tighten the siphon hose and bleed line wrench tight.

2. One gun operation:

Attach the gun and hose. Always use a spray hose at least 50

feet long. Do not use PTFE or thread sealant on this assembly. Do not install the spray tip at this time.

3. Two gun operation:

Remove the plug from the second gun outlet. Replace with

nipple, part # 812-003 for 1/4” hose or nipple; use part # 808555 for 3/8” hose. Connect a hose and a gun to the outlet.

4. Multiple gun operation:

The Hydra Pro IV™ is engineerd to handle up to 4 guns. When

using more than two guns, make sure the second gun hookup outlet is plugged. Connect the multiple gun manifold to the single gun outlet. These manifolds are for either 2, 3, or 4 guns and have shuto valves. Connect a hose and gun to each outlet.

6. Be sure the Hydra Pro IV™ system is grounded. All Titan units are equipped with a grounding lug. A grounding cable (not supplied) should be used to connect the unit to a true earth ground. Check your loack electrical regulations for detailed grounding instructions.

Proper grounding is important. This applies to both gas and electric powered models. The passage of some materials through the nylon fluid hose will build up a static electric charge, which if discharged, could ignite solvent vaports present and create an explosion.

7. Strain all paints to assure trouble-free operation and freedom from frequent cleaning of inlet screen and gun strainer.

Operation

Fueling (gas engine)

Gasoline is extremely flammable and is explosive under certain conditions.

• ALWAYS turn the engine o before refueling.

• Refuel in a well-ventilated area.

• Do not smoke or allow ames or sparks in the refueling area or

where gasoline is stored.

• Do not overll the fuel tank. After refueling, make sure the

tank cap is closed properly and securely.

• Be careful not to spill fuel when refueling. Spilled fuel or fuel

vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine.

• Avoid repeated or prolonged contact with skin or breathing of

vapor.

• Keep out of the reach of children.

Fuel Specications

• Use automotive gasoline that has a pump octane number of

86 or higher, or that has a research octane number of 91 or higher. Use of a lower octane gasoline can cause persistent “pinging” or heavy “spark knock” (a metallic rapping noise) which, if severe, can lead to engine damage.

NOTE: If “spark knock” or “pinging” occurs at a steady

engine speed under normal load, change brands of gasoline. If spark knock or pinging persists, consult an authorized dealer of the engine manufacturer. Failure to do so is considered misuse, and damage caused by misuse is not covered by the engine manufacturer’s limited warranty.

Occasionally you may experience light spark knock

while operating under heavy loads. This is no cause for concern, it simply means your engine is operating eciently.

• Unleaded fuel produces fewer engine and spark plug deposits

and extends the life of the exhaust system components.

• Never use stale or contaminated gasoline or an oil/gasoline

mixture. Avoid getting dirt, dust, or water in the fuel tank.

5. Fill the wet-cup 1/2 full with Titan’s Piston Lube, part # 314480 supplied by the factory. This extends packing life.

Operation

Startup

1. Areas must be well-ventilated to prevent hazardous operation with volatile solvents or exhaust fumes.

If lacquer or other flammable materials are to be sprayed, ALWAYS locate the unit outside the immediate spraying area. Failure to do so may cause an explosion.

2. Locate the unit outside the immediate spraying area to avoid clogged air intake of the engine or electric motor with overspray.

3. Before starting the unit, check oil levels:

a. The hydraulic uid level should read “Full” on the dipstick. Check

it daily. See the hydraulic system maintenance instructions for changing or adding hydraulic uid. Do not overll. Use only Titan Coolo™, part no. 430-361.

b. The gasoline engine oil level is determined by the manufacturer.

Check the manufacturer’s service manual supplied.

4. Open the orange handle shut-o valve located on the hydraulic return hose. Handle should be in line with hose. The gure below shows the handle in the open position.

7. Repeat above starting procedure with paint material. Lock gun trigger and attach spray tip. See the Technical Data Sheet or Operator’s Manual on the gun provided for installation and selection of the proper tip sizes.

8. Test spray pattern. Operate the pump at the lowest hydraulic pressure which provides good atomization. See the Troubleshooting Guide if you are not getting the proper pattern.

9. Operating pressure is adjustable from 500 to 3300 psi by turning the pressure adjustment knob clocwise. Do not turn the knob clockwise more than necessary to provide satisfactory atomization. Excess pressure wears out spray tips.

10. When restarting the unit, reduce the pressure at pressure control adjustment knob and pressure bleed valve.

5. Turn the pressure adjustment knob counterclockwise to lowest pressure setting.

6. Open the pressure bleed valve by turning it counterclockwise. This relieves pressure. See gure below.

a. Your new sprayer was tested at the factory with water soluble oil.

You must clean the system before spraying to avoid contamination of the sprayed material.

If you are spraying a water-based latex, ush with warm, soapy

water followed by a clean water rinse.

If you are using any other coating, ush with warm, soapy water

followed by a solvent. Check with the material manufacturer for a

compatible solvent. Place siphon tube assembly into proper solvent or water. b. Place waste container below bleed line. c. Start engine. Turn pressure control adjustment knob clockwise

(increasing pressure) until pump cycles evenly and solvent ows

freely from bleed line. d. Close pressure bleed valve by turning it clockwise. This allows the

system to pressurize. Hold gun trigger open, without spray tip

attached, until the uid ows smoothly. See gure below.

Pressure Relief Procedure

IMPORTANT: Always reduce pressure when you are cleaning a clogged tip, changing a tip, servicing any part of the system, or shutting down. Follow the steps below.

1. Engage the gun trigger lock.

2. Shut o the power source.

3. Close the orange handle shut-o ball valve on the hydraulic hose.

4. Open the pressure bleed valve by turning it counterclockwise at least three full turns.

5. Disengage the gun trigger lock and hold trigger open until ow of material stops.

6. Be certain to hold a metal part of the gun rmly to the side of a grounded metal container.

Cleaning a Clogged Tip

1. Follow the Pressure Relief Procedure, page 7.

2. Lock the gun trigger.

3. Unthread the safety tip guard and remove the spray tip. Wash the tip in solvent and use a tip probe to remove any clogged material.

4. Release the gun trigger lock and spray briey into a waste container to blow out any clogged particles.

5. Reset the trigger lock in the “Trigger Locked” position. Release the trigger lock and resume spraying.

The flow from the spray tip is at very high pressure. Contact with any body part may be dangerous. Do not place finger on gun outlet. Do not point the gun at any person. Never operate the spray gun without the proper tip guard.

Color Change / Clean Out / Flushing

IMPORTANT: Use only compatible solvents when cleaning out oil based enamels, lacquers, coal tar, and epoxies. Check with the fluid manufacturer for a recommended solvent.

1. Reduce pressure by turning the pressure adjustment knob and the pressure bleed valve on the bleed line counterclockwise. Follow the Pressure Relief Procedure, page

The pressure bleed valve should be turned counter-clockwise

three full turns.

2. Pull the siphon tube out of the material container.

3. Remove the spray tip from the gun. Hold the gun trigger open until material ow stops.

4. Put siphon tube into wash solvent or water as applicable, and operate pump slowly at low pressure until solvent ows freely from pressure bleed valve line.

5. Close pressure bleed valve and hold gun trigger open until solvent ows freely from gun. If solvent is not too dirty, recirculate it by owing gun stream back into solvent container. Use additional clean solvent and repeat procedure if necessary.

6. Check gun strainer screen and pump outlet lter screen daily. Use 50 mesh screens with spray tip size .018 and larger. Use 100 or 200 mesh screens with spray tip sizes .015 and smaller.

7. Replace paint lter cap to maximize clockwise rotation. The lter cover should be hand removable after the rst or second use with new Telfon O-ring.

IMPORTANT: O-ring must have PTFE backup washer to seal properly.

8. If unit has been spraying a water soluble material, ush with water and then repeat procedure with mineral spirits or Varsol solvent.

9. Wash spray tip in solvent. Blow tip clean with air pressure directed through the tip in the reverse direction.

Maintenance

Hydraulic System

1. Check the hydraulic uid daily. It should read “Full” on the dipstick. If it is low, add only Titan Coolo, part # 430-361. Never add or change hydraulic uid except in a clean, dustfree environment. Contamination of the hydraulic uid will shorten hydraulic pump life and may void warranty.

2. Change the hydraulic uid every six months. Drain old uid from tank and ll with 5 gallons of Coolo. Start operation of the system at just enough pressure to operate the uid pump. Run the system at this low pressure for at least 5 minutes. This removes air from the system. Check the uid level after this procedure.

3. The hydraulic system has an external replaceable hydraulic lter. Change the lter every six months.

4. The hydraulic pump should not be serviced in the eld. If service on the hydraulic pump is required, it must be returned to Titan.

General Fluid Pump Maintenance

If the paint pump is going to be out of service for an extended period of time, it is recommended that following cleanup a kerosene and oil mixture be introduced as a preservative. Packings may tend to dry out from lack of use. This is particularly true of the upper packing set for which upper packing lubricant, Titan part # 314480, is recommended in normal usage. A sample of Piston Lube accompanies each new unit. Do not substitute water or paint solvent for Piston Lube. Ordinary oil may contaminate the paint material and is not recommended.

If the paint pump has been out of service for an extended period of time, it may be necessary to prime the suction by pouring some of the paint solvent into the inlet siphon tube to restart. It is extremely

important that the threads on the inlet siphon hose coupling are properly sealed. Any air leakage will produce erratic operation of pump and may damage the system. The up and down strokes

shoudl be approximately equal in time. That is, one should not be faster than the other. A fast up or down stroke may indicate air in the system or malfunctioning valve or seats. See the Troubleshooting Guide.

Hydraulic Motor & Fluid Pump Service

See the individual Technical Data Sheets for maintenance and service instructions on the reciprocating hydraulic motor and the uid pump.

Basic Engine Maintenance

• For detailed engine maintenance and technical specications

refer to the separate gasoline engine manual.

• All service to the engine should be performed by a dealer

authorized by the engine manufacturer. To locate a dealer in your area, look in the Yellow Pages of your telephone directory under Gasoline Engines, Garden & Lawn Equipment & Supplies, Lawn Mowers, etc.

• The gas engine is warranted exclusively by the engine

manufacturer.

• Use a premium quality motor oil certied to meet or

exceed U.S. Automotive requirement SG.or SF. SAE 10W30 is recommended for general all temperature use. Other viscosities may be required in other climates.

• Use only a (NGK) BP6ES or BPR6E spark plug. Gap the plug

to 0.028 to 0.031 In. (0.7 to 0.8 mm) Always use a spark plug wrench.

Daily

1. Check engine oil level, and ll as necessary.

2. Check gasoline level, and ll as necessary.

Always follow the fueling procedure outlined earlier in this manual.

First 5 Hours

1. Change engine oil.

Every 25 Hours

1. Change engine oil.

Weekly

1. Remove the air lter cover and clean the element. In very dusty environments, check the lter daily. Replace the element as needed. Replacement elements can be purchased from your local engine dealer.

Engine Operation and Service

1. Clean and oil air lter pad on gasoline engine every 25 hours or once weekly. Do not permit the air intake screen around the y wheel of the gas engine to load up with paint or trash. Clean it regularly. The service life and eciency of the gas engine model depends upon keeping the gasoline engine running properly. Change the oil in the engine every 100 hours. Failure to observe this may result in engine overheating. Consult the engine manufacturer’s service manual provided.

2. To conserve fuel, service life, and eciency of the sprayer, always operate the gasoline engine at the lowest RPM at which it runs smoothly without laboring and delivers the amount required for the particular painting operation. Higher RPM does not produce higher working pressure. The gasoline engine is connected to the hydraulic pump by a pulley combination designed to produce full paint delivery at maximum RPM.

3. The warranty on gasoline engines or electric motors is limited to the original manufacturer.
