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, serious
injury 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.
WARNING
Safety

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

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.
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.
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.
• 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.

If your unit is not operating properly, try using these troubleshooting tips:
Troubleshooting Your Unit
Issue Solution
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.
Pump is cycling slower than
normal
• 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
reduced 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 o 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.
