• Filter: If the unit is equipped with a filter, check and change it at regular intervals. A dirty
filter in a pump or remote dispenser will cause a slower delivery rate. Refer to the
accessories section of your parts manual to ensure that you replace the filter with one
designed for your model. Always use a drip pan directly below the filter when removing
the cartridge to prevent contamination of both the soil and the electrical components
within the cabinet.
• Clean the Strainer: Clean the strainer immediately after the pump has been installed and
tested, and again after a few hundred gallons have been delivered. Thereafter, once every
six months, or as required. The symptoms of a dirty or clogged strainer in a pump are slow
delivery, noisy operation, and pulsation.
Note: This procedure should be performed only by an authorized Gasboy distributor or
installer.
To clean the strainer, proceed as follows:
1 Turn off and lock out AC power to the pump.
2 Unthread the drain plug located near the bottom of the strainer (marked “Filter”) cap. Ensure
that you use a container of sufficient capacity to catch the fuel as it drains from the pump.
3 Loosen the four bolts that hold the cap in place.
4 Carefully remove this cap which holds the spring, strainer, and inlet check valve assembly in
place.
5 Use compressed air to blow the dirt from the strainer. Always wear protective safety goggles
or glasses when using compressed air.
6 Replace the inlet check valve, strainer, and spring and reinstall the strainer cap. Ensure that the
O-Ring that seals the cap is installed properly before tightening the bolts.
7 Reinstall the drain plug using sealing compound approved for this application.
• Lubrication: Lubricate the start/stop linkage. Apply one drop of oil (SAE10) at each
pivot point of the start/stop linkage every six months.
• Adjusting the Belts (Suction Pumps Only): With proper care, belts will give
exceptionally good service. A loose belt not only cuts down dispensing speed due to
slipping, but also results in excessive wear. A properly tightened belt will allow twisting
the belt 180 degrees midway between the motor and the pump pulleys. Before adjusting
any belt, turn off AC power to the pump/remote dispenser.
The belt can be tightened by loosening the hex nut which holds the idler pulley and sliding
the pulley to the side to obtain the correct belt tension of 6-3/4 lbs. + 3/4 (30N, +3.3N).
When the adjustment is complete, remember to retighten the hex nut.
• Preserve the Finish of Your Pumps: Nearly all gasoline pumps are installed outdoors
where their surfaces are subjected to the action of the weather. As a result, it is necessary
to give the finish a reasonable amount of care if an attractive appearance is to be
maintained.
