Operate with Reasonable Care
Like any machine, the pump that is operated with reasonable care will last longer and give
better service. Abuse should be avoided (such as dropping the nozzle on the ground, operating
the unit with a dirty strainer, dragging the hose across the concrete island or driveway, running
the pump with the nozzle closed for more than two minutes and so on). Parts that fail from
abuse will not be covered by warranty. The time and care given to your pumps will be returned
to you in the form of dependable service.
Preventive Maintenance
Refer to the “Important Safety Information” on page 5 and read and understand all the
information contained there. It is recommended that all service to this unit be done by
Certified Gasboy ASCs familiar with the operation of this equipment and safety requirements
for servicing equipment in potentially hazardous condition or location.
Keep Water Out
Water tends to collect in storage tanks. This is due to moisture-laden air being drawn into the
storage tank and condensing, or to defective fill openings that are not properly protected with
watertight covers. Storage tanks should be checked after every fill-up for water and removed
with a sump pump, to forestall serious damage to equipment. Water, sediment, and other
foreign matter that accumulates in the tank can be drawn up into the pump and cause failures.
Clean the Dial Face
Clean the dial face with a soft, clean, damp cloth as often as necessary. Do not use abrasive
cleaners or those containing ammonia.
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 whenever a
filter is changed. The symptoms of a dirty or clogged strainer in a pump are slow delivery,
noisy operation, and pulsation. To clean the strainer, turn off AC power to the pump. Locate
the Suction Strainer Cap on the plumbing unit and unscrew it to access and remove the
strainer. Use compressed air to blow the dirt out of the strainer. Clogged strainers can
commonly be cleaned using alcohol. Refer to item 3 in the parts list under
“Meter Assembly”
on page 24.
Always wear protective safety goggles or glasses when using compressed air.
