5 OPERATOR MAINTENANCE
5.1 Preventive Maintenance
The safety precautions described in Section 1.3 apply to the following preventive maintenance procedures. A
correctly installed dispenser, given proper preventive maintenance attention, will seldom require emergency
service. 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 defects repaired immediately.
Do not abuse the hose by trying to stretch it to reach an automobile. This will cause early failure at the cou-
plings.
Keep the dispenser clean at all times. 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 dis-
penser. All stainless steel surfaces require polishing with a non-abrasive silicone wax a minimum of three
times per year to maintain a bright finish and prevent corrosion. If it is necessary to just wipe off the dis-
penser, use a damp cloth. See Section 5.3 for additional information on cleaning and corrosion prevention.
NOTE: Do not spray the dispenser with water.
Before removing the bezel, wipe off any water lying along the top edge of the dispenser so it will not run
inside when the bezel is removed.
If the bezels must be removed during rainy weather, take care to prevent rain from getting inside the
dispenser.
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. If this does not operate easily, too much force may be applied on
the switch mechanisms, causing premature failure.
Periodically check and lubricate all key lock cylinders and locking mechanisms.
5.2 Strainer/Filter
A dirty strainer screen and/or fuel filter will slow down the delivery of product. See Figure 2-3 for location. If
the underground installation is new, it may be necessary to replace the filter and clean the strainer screen two or
three times during the first few days of operation to remove installation debris and pipe sealant. After this, filter
replacement and strainer cleaning should be performed periodically.
WARNING
Before removing the filter and strainer turn the power to the dispenser and submersible pump(s) off and
close the emergency shut-off valves on the dispenser being serviced. Failure to do so may result in a haz-
ardous condition that can result in serious injury. Loosen strainer cap or spin-on filter slightly and allow
gasoline to drain into a plastic container until pressure is relieved. Return product to the appropriate under-
ground tank.
