Grounding Instructions

Electric models must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

DANGER — Improper installation of the grounding plug can result in a risk of electric shock. If repair or replacement of the cord or plug is necessary, do not connect the green grounding wire to either flat blade terminal. The wire with insulation having a green outer surface with or without yellow stripes is the grounding wire and must be connected to the grounding pin.

Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided. If the plug will not fit the outlet, have the proper outlet installed by a qualified electrician.

This product is rated more than 15 amperes and is for use on a circuit having a nominal rating of 120 volts, or the product is for use on a circuit having a nominal rating more than 120 volts, and is factory-equipped with a specific electric cord and plug to permit connection to a proper electric circuit. Make sure that the product is connected to an outlet having the same configuration as the plug. No adapter should be used with this product. If the product must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel.

CAUTION

Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that will accept the plug on the product. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. For lengths less than 50 feet, No. 12 AWG extension cords should be used. If an extension cord is to be used outdoors, it must be marked with the suffix W-A after the cord type designation. For example, a designation of SJTW-A would indicate that the cord would be appropriate for outdoor use.

•5 gallon siphon hose and bleed line assemblies are standard

You have made an excellent choice. We know you will be pleased with your new PowrTwin. Thanks again for selecting Speeflo. We appreciate your business.

Operation

Fueling (gas engine)

WARNING

Gasoline is extremely flammable and is explosive under certain conditions.

•ALWAYS turn the engine off before refueling.

•Refuel in a well-ventilated area.

•Do not smoke or allow flames or sparks in the refueling area or where gasoline is stored.

•Do not overfill 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 Specifications

•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 efficiently.

•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.

Gasolines Containing Alcohol

If you decide to use a gasoline containing alcohol (gasohol), be sure its octane rating is at least as high as that recommended by the engine manufacturer. There are two types of "gasohol": one containing ethanol, and the other containing methanol. Do not use gasohol that contains more than 10% ethanol. Do not use gasoline containing methanol (methyl or wood alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol. Never use gasoline containing more than 5% methanol, even if it has cosolvents and corrosion inhibitors.

NOTE: Fuel system damage or engine performance problems resulting from the use of fuels that contain alcohol is not covered under the warranty. The engine manufacturer cannot endorse the use of fuels containing methanol since evidence of their suitability is incomplete at this time.

Before buying gasoline from an unfamiliar station, try to find out if the gasoline contains alcohol. If it does, confirm the type and percentage of alcohol used. If you notice any undesirable operating characteristics while using a gasoline that contains alcohol, or one that you think contains alcohol, switch to a gasoline that you know does not contain alcohol.

Setup

WARNING

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

1.Connect the siphon hose to the fluid section and the bleed

hose to the bleed valve. They each have factory installed PTFE tape on the male end of the hoses and should be tightened wrench tight.

Bleed Valve

Hose

Fluid Section

Siphon Hose

2.Attach a minimum of 50’ of nylon airless spray hose to the unit. Do not use PTFE tape or thread sealant on the spray hose connection.

3.Attach an airless spray gun to the spray hose. Do not attach the tip to the spray gun yet. Remove the tip if it is already attached.

a.To use two guns, remove the plug from the second gun outlet on the filter assembly. Connect a hose and gun to the outlet.

NOTE: The gas unit is engineered to handle up to 5 guns with .021" tips and the electric unit is engineered to handle up to 3 guns with .019” tips. For multiple gun operation, connect a multiple gun manifold to the single gun outlet. Connect a hose and gun to each outlet. Make sure the second gun outlet remains plugged.

4.Fill the oil cup 1/2 full with Speeflo Piston Lube (P/N 700-925) supplied by the factory. This extends packing life.

Multiple Gun

Manifold

5.Check the hydraulic fluid level daily before starting the unit. The hydraulic fluid level should be at the “Full” mark on the dipstick. Refer to the Maintenance section of this manual for hydraulic system maintenance instructions.

CAUTION

Use of Speeflo's Coolflo™ Hydraulic Fluid is mandatory in the hydraulic system. Do not use any other hydraulic fluid. Use of any other hydraulic fluid may seriously damage the hydraulic system and will void the warranty.

6.For gas models, check the engine oil level daily before starting the unit. The gasoline engine oil level is determined by the engine manufacturer. Refer to the engine manufacturer’s service manual supplied with this unit.

7.For electric models, use a 20 amp service outlet. Always locate the electric model within 10 to 15 feet of the service outlet. Use a short electric cable and a long paint hose.

Any extension cord will create some voltage drop. If an extension cord is necessary, use only a grounded 3-wire #12 extension cord.

NOTE: If the unit is being operated in an area that is overloaded by other appliances or low voltage conditions, it is important to start the unit "unloaded." Tip the electric motor forward so that the belt is loosened and the motor starts without full load. This reduces the amperage draw on starting and may avoid tripping the circuit breaker.

8.Make sure the unit is grounded. All 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 local electrical regulations for detailed grounding instructions. See the Accessories and Service Kits section near the back of this manual for grounding cable ordering information.

WARNING

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 vapors present and create an explosion.

9.Strain all paints with a nylon strainer to ensure trouble free operation and freedom from frequent cleaning of the inlet screen and gun filter.

10Make sure the spray area is well ventilated to prevent hazardous operation with volatile solvents or exhaust fumes.

WARNING

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.

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

Maintaining the Filter Assembly

Clean the filter regularly. Dirty or clogged filters can greatly reduce filtering ability and cause a number of system problems including poor spray patterns, clogged spray tips, etc.

Cleaning

To clean the filter, perform the following procedure.

1.Follow the “Pressure Relief Procedure” found in the Operation section of this manual.

2.Remove the filter cap assembly

and spring.

3. Pull the filter element with ball straight out of the filter body.

4. Clean inside the filter body, filter element with ball, and filter cap assembly using the appropriate solvent.

NOTE: Use care in handling parts as dirt, debris, scratches, or nicks may prevent o-rings or gaskets from sealing.

This filter element filters from the inside out. Be sure to clean the filter element thoroughly on the inside. Soak in solvent to loosen hardened paint or replace.

Inspection

Inspect all parts of the filter assembly before reassembly.

1.Inspect the ball inside the filter element. If the ball has pressure cuts or scratches, replace the filter element.

a.If the ball is cut, remove the PTFE o-ring using an o- ring pick and remove the carbide seat.

b.Check the seat for nicks or grooves. If the seat is damaged, replace.

NOTE: Removal of the PTFE o-ring will damage the o-ring and require replacement.

2.Remove the spring from the spring guide on the filter cap.

a.Measure the length of the spring uncompressed. If it measures less than 3/4” from end to end, replace.

b.Push the spring back onto the spring guide until it “snaps” back into position.

3.Inspect the two PTFE gaskets and the PTFE o-ring for deformity, nicks, or cuts. Replace, if needed.

NOTE: The PTFE gaskets, PTFE o-ring, and spring are packaged in Filter Service Kit P/N 930-050.

Reassembly

After cleaning and inspecting all parts, reassemble the filter.

1.Place the carbide seat into the filter body. Make sure the beveled side of the seat is facing up.

2.Place the PTFE o-ring into the groove on the outer diameter of the carbide seat.

3.Place the filter element with ball into the filter body.

NOTE: The top and bottom of the filter element with ball are identical.

4.Push the spring back onto the spring guide of the filter cap until it “snaps” back into position, if not already done.

5.Place the thin PTFE gasket onto the step at the top of the filter body.

6.Place the thick PTFE gasket onto the top of the thin gasket.

7.Tighten the filter cap assembly onto the filter body.

Maintaining the Hydraulic System

CAUTION

Use of Speeflo's Coolflo™ Hydraulic Fluid is mandatory in the PowrTwin hydraulic system. Do not use any other hydraulic fluid. Use of any other hydraulic fluid may seriously damage the hydraulic system and will void the warranty.

1.Check the hydraulic fluid daily. It should be at the “Full” mark on the dipstick. If it is low, add only Speeflo Coolflo™ Hydraulic Fluid (P/N 430-361). Never add or change hydraulic fluid except in a clean, dust-free area. Contamination of the hydraulic fluid will shorten hydraulic pump life and may void warranty.

Hydraulic Fluid

Cap/Dipstick

"Full" Mark

Hydraulic

Filter

2.Change the hydraulic fluid every twelve months. Drain the old fluid from the tank and fill with 5 quarts of Speeflo Coolflo™ Hydraulic Fluid. Start the unit at just enough pressure to operate the fluid section. Run the unit at this low pressure for at least 5 minutes. This removes air from the system. Check the fluid level after this procedure.

3.The hydraulic system has an external, replaceable hydraulic filter. Change the filter every twelve months.

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

Maintaining the Fluid Section

If the sprayer 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 Piston Lube (P/N 700-925) is recommended in normal usage.

If the sprayer 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 siphon tube to restart. It is extremely important that the threads on the siphon hose coupling are properly sealed. Any air leakage will produce erratic operation of the sprayer and may damage the system. The up and the down strokes should be approximately equal in time (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 section).

Basic Engine Maintenance (gas engine)

•For detailed engine maintenance and technical specifications refer to the separate gasoline engine manual.

•All service to the engine should be performed by an authorized Honda Power Equipment dealer. 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 Honda engine is warranted exclusively by American Honda Motor Co., Inc.

•Use a premium quality motor oil certified 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 fill as necessary.

2.Check gasoline level, and fill as necessary.

WARNING

Always follow the fueling procedure outlined earlier in this manual.

First 20 Hours

1. Change engine oil.

Every 100 Hours

1.Change engine oil.

2.Clean the sediment cup.

3.Clean and re-gap the spark plug.

4.Clean the spark arrestor.

Weekly

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

Engine Operation and Service

1.Clean and oil air filter pad on gasoline engine every 25 hours or once weekly. Do not permit the air intake screen around the fly wheel of the gas engine to load up with paint or trash. Clean it regularly. The service life and efficiency 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 efficiency of the unit, 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 of 1.2 GPM at maximum RPM.

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

Service Instructions

This bleed valve has a tungsten carbide valve seat and should not require frequent replacement. The tungsten carbide ball, in normal service, will last a long time because it rotates and wears evenly. If there is leakage, replace the ball.

CAUTION

Open the adjustment knob, to full counterclockwise position before unthreading valve seat, from valve body. If the valve stem is rotated inwardly with the ball removed, the 37)( o-ring may require replacement. If there has been leakage from the valve stem, the 37)( o-ring should be replaced

NOTE: The valve stem stop must be unthreaded from the valve stem with a socket screwdriver, then the valve stem can be threaded out of the valve body.

CAUTION

All non-moving threads must be assembled with Speeflo Loctite Sealant (P/N 426-051).

4.Remove cylinder head plug (7).

5.Loosen lock ring (22) with a spanner wrench and unthread tube retaining nut on tee (27). Loosen tube retaining nut on elbow (15). Slide the nut down. Push motor tube (26) into tee (27) far enough to clear elbow (15). Slowly unthread cylinder head (11) and Iift it just high enough above the cylinder (23) to reach the valve rod assembly

(20)with vise grip pliers.

6.The piston rod (21) should be near the top of its stroke for disassembly. It may be necessary to use a wood or nylon driver to push the piston rod up to its top position.

7.Grip the valve rod securely with vise grip pliers and then remove the FlexLoc nut (9) from the top of the valve rod assembly (20). Be careful that spool (5) does not fall. The cylinder head (11) can now be lifted off. Unthread the cylinder (23) from the motor/pump block (25). Note: An extra lock ring (22) can be used to jam the two lock rings together on the cylinder and a pipe wrench can be used to unthread the cylinder (23) from the motor/pump block

8.To remove the connecting pin, slide the retaining ring down with a small screwdriver, and then push the connecting pin out.

9.Remove the piston rod assembly from the motor/pump block (25).

10.Remove rod seal (24), being extremely careful not to scratch the seal groove in the motor/pump block (25).

11.Place the piston retainer screw (16) on the piston rod assembly in a vise. Slide a long bar through the hole at the base of the piston rod for leverage, and unthread the piston rod from the piston retainer screw.

12.Remove piston (17) and lift out valve rod assembly (20).

13.Remove piston seal (18) and o-ring (19).

14.Remove trip retainers (1), trip springs (3), and balls (4) from cylinder head (11). Remove o-rings (2) from trip retainers (1).

15.Remove retaining ring (14) and sleeve retainer (13). Gently tap spool/sleeve set (5) out of cylinder head (11) using a wood or nylon rod.

16.Inspect piston rod (21) and cylinder (23) for wear, scratches, and dents. Replace if damaged.

17.Inspect spool valve (5) for wear. Replace if necessary. spool valve should move smoothly and freely with no force by holding in a vertical position. If it does not, it can cause the motor to stall.

Reassembling the Hydraulic Motor

1.Separate spool/sleeve set (5). Place o-rings (6) onto sleeve. Lubricate o-rings with hydraulic oil. Gently push the sleeve into cylinder head (11) with the flatter side of the sleeve facing out. Use a nylon rod to tap sleeve down until it reaches its full depth. Do not use any other type of tool that might damage or leave particles or residue on the sleeve. Install the spool through the top of the cylinder head, down into the sleeve.

CAUTION

Do not use Piston Lube pump packing lubricant. It is a solvent and will severely damage seals and O-Rings of the hydraulic motor.

2.Install o-rings (2) on trip retainers (1). Install trip retainer balls (4) followed by springs (3) which, when installed, will hold spool/sleeve set (5) in proper place for assembly.

3.Install sleeve retainer (13) followed by snap ring (14) into cylinder head (11), which will hold valve sleeve in place. Install o-ring (12) in the o-ring groove of the cylinder head.

4.Replace lower seal (24) in motor/pump block (25). Be sure the open portion of the seal is facing upward (V). This seal requires no special tool.

5.Place piston rod (21) in vise. Inspect valve rod assembly

(20)for any damage. Make sure the lock nut at the bottom of the valve rod assembly (20) is secure. DO NOT remove. Then, place into piston rod (21) as illustrated. Install o-ring (19), lubricating it well and replacing piston

(17)onto piston rod (21). Put one drop of blue Loctite on the piston retainer screw (16). Tighten piston retainer screw until piston is locked into place. Check valve rod assembly (20) for normal spring action at this time.

6.Install piston seal (18) with lips facing downward. Carefully install o-ring (19). Expand the ring and stretch it sufficiently for installation.

7.With motor/pump block (25) still in vise, install lower seal

(24)by pushing it towards its groove with a properly sized blunt rod. Then complete installation with the fingers. No tool is necessary. Do not twist the seal.

8.Pre-lubricate the piston and valve rod assembly with Coolflo™ hydraulic fluid (P/N 430-361). Install piston rod

(21)into motor/pump block (25) with a gently pushing and rotating motion to work the piston rod in through the seal

NOTE: Inspect the bottom of piston rod (21) for nicks or sharp areas that could damage the piston seal during installation through the motor/pump block (25).

9.Replace the connecting rod pin and retainer ring.

10.Install o-ring (12) on cylinder wall. Lubricate ring and inner wall. With the piston rod held firmly, the cylinder should be gently driven over the piston seal with a rubber mallet. Tightly thread the cylinder into motor/pump block (25).

11.Raise piston rod (21) to top position and thread lock ring

(22)all the way up on upper threads of cylinder (23).

12.Pull valve rod assembly (20) up as far as it will travel and grasp it with vise grip pliers. Then install cylinder head (11), already assembled, over valve rod until the top threads of the valve rod pass through the top of the spool/sleeve set (5). The valve rod threads must be clean and free of oil. Place one drop of blue Loctite on threads of flex lock nut (9) and thread nut onto valve rod to full tight position (do not over-tighten) while holding valve rod below with vise grip pliers.

13.Thread cylinder head (11) down onto the cylinder (23) and then back off just enough to reassemble hydraulic fittings and motor tube (26). Tighten lock ring with spanner wrench to hold cylinder head in position.

14.The tee assembly (27) and the elbow (15) use an o-ring

(28)to seal on the outer diameter (O.D.) of the motor tube

(26).The O.D. of the motor tube should be free of scratches or sharp edges. The lock nuts on these fittings first should be hand tightened, then wrench tightened another half turn.

15.Install o-ring (8) onto cylinder head plug (7). Tighten.
