Safety

WARNING

PEOPLE OR OBJECTS CAN BE HURT OR DAMAGED IF THIS UNIT IS NOT USED CORRECTLY!
Failure to read all the instructions before operating the unit may result in personal injury or death from the improper use or the chemical solution. Anyone handling, operating or using the unit must read and understand the instructions in the manual. The buyer assumes all responsibility for safety and proper use in accordance with the instructions.
Using or servicing the unit without appropriate personal protective equipment (PPE) may result in serious injury such as burns, rashes, eye, throat or lung damage and death. Always wear PPE as indicated in the Safety Data Sheet (SDS) when using or servicing the unit. Protect eyes, skin, and lungs against drifting spray.
Chemical solutions may pose a health risk and death if they contact the skin or eyes, are inhaled or swallowed. Always read and follow all chemical safety precautions and handling instructions provided by the chemical manufacturer and the SDS associated with the chemical solution before using the unit.
Pressure within the equipment may cause an unexpected release of the chemical solution and cause serious injury such as burns, rashes, eye damage, throat or lung damage and death.
Always depressurize and clean the unit after each use. Release any remaining air pressure by opening the discharge ball valve. Never leave the unit unattended while pressurized.
Using the unit with fluid temperatures above 100°F (37.77°C) may result in scalding, burns, serious injury or death. DO NOT use a solution with a temperature above 100°F (37.77°C).
Operating the unit when damaged or leaking may result in exposure to chemical solutions, seriousinjury or death. Never use the unit if it is damaged or leaking.
Never point the discharge wand at yourself, another person, or any object you do not want covered in chemical.
Using incoming air pressure exceeding 100 psi (6.9 bar) may result in pressure buildup, explosion, serious injury or death. DO NOT exceed 100 psi (6.9 bar) incoming air pressure when operating the unit.
Use of hydrocarbons and flammable products may result in explosions, fire and serious injury or death.
Never use hydrocarbons or flammable products with the unit.
Mixing an alkaline with an acid may result in a chemical reaction. Overheating of the mixture may cause it to splatter caustic compounds or release hazardous fumes, gas and vapors. Always flush the unit with fresh water thoroughly when switching from an alkaline to an acid or an acid to an alkaline.

NOTICE

Servicing or modifying this unit with parts not listed in this manual may cause the unit to operate improperly. Do not use unauthorized parts when servicing the unit.
Use of an air lubricator before the unit may result in diminished performance and damage to the unit. Do not use an air lubricator before the unit.
Moisture in the air lines will damage the pump and diminish the pump life. The air must be filtered, clean, dry and free of moisture. If needed, install an air dryer before the unit.
PROTECT THE ENVIRONMENT
Please dispose of packaging materials, old machine components, and hazardous fluids in an environmentally safe way according to local waste disposal regulations

   After Use Instructions
   NOTE : For proper handling and disposal procedures refer to chemical SDS.

10. Solution should be removed from unit after each use. This can be done in two ways:
    a. Unthread drain plug from front of tank and drain solution into an approved location.
    b. Place discharge wand into approved container to transfer remaining solution. Activate unit until all solution has been flushed from the system.

11. After solution has been removed, disconnect air line.

12. Open discharge ball valve or pull trigger handle to relieve remaining pressure.

13. Close ball valve or release trigger handle after all pressure has been relieved. Store unit with discharge ball valve and air inlet valve closed.

14. Before using unit with another chemistry, thoroughly flush with water.

Maintenance

WARNING
Performing any maintenance with the unit pressurized, and connected to the air supply may result in serious injury or death. Always ensure that the unit has been depressurized, and disconnected from the air supply before conducting any maintenance. Servicing or modifying this unit with parts not listed in this manual may cause the unit to operate improperly. Do not use unauthorized parts when servicing the unit.

Maintaining Your Unit

To keep your unit operating properly, periodically perform the following maintenance procedures:

• Inspect the pump for wear and leaks.

• Inspect all hoses for leaks or excessive wear.
  Make sure all hose clamps are in good condition and properly secured.

• Replace the filter located within the air regulator as needed. Clean by unthreading the air regulator bowl from the air regulator.

• Check the suction line and strainer for debris.
  Clean as needed.

• Drain your air compressor tank on a regular basis to help extend pump life. An air source with a high moisture content will accelerate pump wear.
  Note : If your air source has a high moisture content, install a water separator to the air fitting on the backplate.

Servicing Your Unit

To service your unit, refer to the service manual which includes:

• Troubleshooting procedures.
• Detailed parts breakdowns and illustrations.
• Part numbers of serviceable components and assemblies.

Troubleshooting Your Unit

If your unit is not operating properly, try using these troubleshooting tips:

Air regulator bowl or air filter has debris such as water, oil, or rust particles| Clean by unthreading the air regulator bowl from the air regulator.
Pump is cycling faster than normal
,| • Verify product is getting to the pump with these steps:
1.Make sure the tank has chemical solution in it.
2.Ensure the suction line valve is open completely.
3.Inspect suction line and strainer for debris or damage. If these steps are confirmed, the pump may need to be replaced.
ump is cycling slower than ormal| • Verify there is no obstruction on the outlet side of system with these steps:
1.Inspect discharge hose assembly for build up.
2.Verify unit is supplied with proper air supply.
• If these steps are confirmed, the pump may need to be replaced.
Air passes through the pump without cycling| • The pump needs to be replaced.
The unit operates at a freduced pressure| • Check suction line and strainer for debris or damage. Clean or replace as needed. To prevent damage to the unit, the strainer must always be used.
• Check the air compressor supplying the unit. If the pressure is less than 40 psi (2.8 bar), turn off the unit until the compressor can catch up.
• If the air supply is 50 psi (3.4 bar) or above, check the air gauge, which should read near 50 psi (3.4 bar). If the air gauge reads more or less than 50 psi (3.4 bar), adjust the pressure by turning the knob on the top of the air regulator.
