5. MAINTENANCE
5.1. Preventive Maintenance
The safety precautions described in Section 1.3 apply to the following preventive
maintenance procedures. A correctly installed pump, given proper preventive maintenance
attention, will seldom require emergency service. Perform the following checks on a regular
basis:
•
Check the pump housing parts for 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 a vehicle. This will cause early
failure at the couplings.
•
Keep the pump 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 pump. Do not use abrasive
cleaners on any part of the pump. If it is necessary to just wipe off the pump, use a damp
cloth. Periodic waxing (3 times per year) of the pump surfaces with an automotive wax or
polish is essential to maintain the original finish and inhibit corrosion.
NOTE: Do not spray the pump with water.
•
Test the tank for water regularly. Water in petroleum is not only a source of engine
trouble, but will also cause damage to the pump.
•
Check the nozzle holder switch operation. If this does not operate easily, too much force
may be applied on the switch mechanisms, causing premature failure.
5.2. Strainer
A dirty strainer screen will slow down the delivery of product. If the tank and piping
installation is new, it may be necessary clean the strainer screen two or three times during the
first few days of operation to remove installation debris and pipe sealant. After this, strainer
cleaning should be performed periodically.
Before removing the strainer, turn off the power to the pump. Failure to do so may result in a
hazardous condition that can result in serious injury. Make sure safety goggles are worn.
Loosen the strainer cover and allow the product to drain into a plastic container until pressure is
relieved. Return the product to the appropriate tank.
