Service Guide
WARNING
Performing any maintenance with the unit pressurized, connected to air supply, and/or connected to electrical power may result in serious injury or death. Always ensure that the unit has been depressurized, disconnected from the air supply, and electrical power 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.
- Ensure all hose clamps are in good condition and properly secured.
- Check suction line and strainer for debris. Clean as needed.
- Inspect nozzles 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. See Page 8 for more details. (Back plate assembly)
Servicing Your Unit
Most repairs on the unit can be performed with the following tools:
- Crescent wrench (2x)
- ⁷/16 in. (11 mm) open-ended wrench

Troubleshooting Your Unit
If your unit is not operating properly, try using these troubleshooting tips:
| Issue | Solution |
| Pump is cycling too fast | Ensure the suction line ball valve at the bottom of the tank is open. |
| Pump is cycling too slow | Inspect the outlet side of pump for build up. Clean as needed. |
| Air passes through the pump without cycling | The pump needs to be replaced. |
| Chemical found in the air bowl or coming out of the pump exhaust | The pump diaphragm is torn, replace pump. |
| The unit operates at a reduced pressure |
