Preventive Maintenance
Schedule
The operating conditions of your system determine how
often maintenance is required. Establish a preventive
maintenance schedule by recording when and what kind
of maintenance is needed, and then determine a regular
schedule for checking your system.

Pressure Relief Procedure

• Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from skin
injection or moving parts.
• Relieve pressure when you stop pumping and
before cleaning, checking, or servicing equipment.
• Do not lift or move motor while pressurized.
1. Shut off the air supply to the pump.
2. Close the bleed-type master valve (required in sys-
tem).
3. Open the fluid ball valve and/or dispensing valve to
relieve fluid pressure.
