AESFill AF1C Machine Manual 54/58 General Maintenance
14. General Maintenance
This is intended as a guide only. Actual maintenance intervals and service schedule will depend upon conditions of use. Product
properties, production environment, quality of compressed air and other variables may contribute to establishing a suitable
preventive maintenance schedule.
Before Each Production Run 14.1
Ensure that all clamps and fittings are tight.
Always ensure a clean dry source of compressed air with a minimum 80 psi. Ensure that the air filter bowl at the rear of the
machine is empty of accumulated moisture from the air supply. If required, place a suitable container under the filter and
slowly open the drain at the bottom of the bowl.
After Each Production Run 14.2
**LEAVING PRODUCT IN THE PUMP OR NOZZLE FOR EXTENDED PERIODS IS NOT RECOMMENDED AS THE SERVICE LIFE
OF SEALS AND INTERNAL COMPONENTS MAY BE COMPROMISED**
1. Turn off the machine.
2. Dismantle the nozzle and clean all parts as required for the product.
a. Inspect and replace any O-rings that show signs of wear.
3. Dismantle the pump and clean all parts as required for the product.
4. Inspect and replace any O-rings that show signs of wear.
a. Pay particular attention to the shaft seal pressed into the recess inside the pump body. It can be removed by
carefully pressing out with a blunt tool, such as the dulled tip of a small screwdriver from the outside of the pump
body. Be careful not to damage the inside contact surface of the shaft seal. If the shaft seal is worn, or the drive
shaft shows signs of wear at the seal location, both should be replaced in order to avoid product leakage past the
seal. If the application permits, smear a small amount of food-grade grease (LOCTITE # 51252 or equivalent) on the
round sections of the drive and idler shafts before assembly.
b. Replace any worn or damaged parts to ensure operator safety and to maintain proper intended functionality of the
machine and its accessories.
5. Clean completely all machine surfaces using only a mild detergent. Avoid solvents especially on plastic surfaces.
Note: The motor is permanently lubricated and requires no maintenance.
The nozzle air cylinder does not require lubrication in the air supply.
Pneumatic Controls for Shut-Off Nozzles 14.3
Care should be taken to make sure that the filter bowl on the filter regulator is cleaned at regular intervals and is not allowed to
become clogged or filled with water, thus allowing water or other contaminants to pass through the pneumatic circuitry.
