5 OPERATOR MAINTENANCE
5.1 Preventive Maintenance
Adhere to the safety precautions on the inside cover and in Section 1.3 of this manual when performing pre-
ventive maintenance. A correctly installed dispenser, given proper preventive maintenance attention, will sel-
dom require emergency service.
Take the following precautions:
• Always make sure ALL power to the dispenser is turned OFF before you open the dispenser cabinet for
maintenance. Physically lock, restrict access to, or tag the circuit breakers you turn off when servicing the
dispenser. Be sure to trip (close) the emergency valve(s) under the dispenser BEFORE beginning mainte-
nance. See Section 5.2 Filter/Strainer instructions.
• Do not spray the dispenser with pressurized water. Pressurized water from a power washer or even a gar-
den hose may cause the water to enter the electronic enclosure.
• Do not abuse the hose by trying to stretch it to reach an automobile. This will cause early failure at the
couplings.
• Hose retractors: Do not abuse the hose by trying to stretch it to reach an automobile. This will cause early
failure at the couplings, cable or clamp. Check the hose retractor periodically for proper pull and retrac-
tion. Check the retractor cable periodically for frays or cuts.
• Do not use pipe sealant (pipe dope) on hose/nozzle threads on dispensers equipped with vapor recovery
assist systems.
Perform the following checks on a regular basis:
• Check the dispenser for internal and external leaks regularly. Check nozzles, swivels, hoses, filters, and
joints for leaks and wear. Have all leaks or defects repaired immediately.
• Keep the dispenser clean at all times. Do not spray the dispenser with water. Use only mild soap and water
with a soft cloth. Do not use gasoline or other petroleum-based products to clean the dispenser. Do not use
abrasive cleaners on any part of the dispenser. See Section 5.3 for specific cleaning procedures.
• If the doors must be removed during rainy weather, take care to prevent rain from getting inside the dis-
penser.
• Test the tank for water regularly. Water in petroleum is not only a source of engine trouble but will also
cause damage to the dispenser.
• Check the nozzle boot switch operation to ensure that the flipper up inside the nozzle boot, or the up/
down side level, depending on model, operates freely. Also see Section 3.12.
