Service Guide

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 regularly 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. 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
• Flat head screwdriver
• Thread seal tape

• 2 Phillips head screwdriver

• 3 Phillips head screwdriver

• Hose cutters
• Knife

Troubleshooting Your Unit

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

The 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.
The pump is cycling improperly| •     Ensure proper chemicals and concentrations are being used.

•     Check to ensure discharge hose is uncoiled properly, and that there are no kinks that could obstruct fluid flow.

Air passes through the pump without cycling| •     The pump needs to be replaced.
The unit operates at a reduced pressure| •     Check the 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.
