equipment, dispensing devices, and submerged turbine
pumps (STPs).

!

WARNING

!

The EMERGENCY STOP, ALL STOP, and
PUMP STOP buttons at the cashier’s station
WILL NOT shut off electrical power to the
pump/dispenser.

Total Electrical Shut-Off Before Access

Any procedure requiring access to electrical components or
the electronics of the dispenser requires total electrical shut­off of that unit. Know the function and location of this switch
or circuit breaker before inspecting, installing, maintaining, or
servicing Gasboy equipment.

Evacuation, Barricading and Shut-Off

Any procedures requiring accessing the pump/dispenser or
STPs requires the following three actions:

This means that even if you activate these
stops, fuel may continue to flow uncontrolled.

You must use the TOTAL ELECTRICAL SHUT­OFF in the case of an emergency and not only
these cashier station “stops.”

Replacement Parts

Use only genuine Gasboy replacement parts and retrofit kits
on your pump/dispenser. Using parts other than genuine
Gasboy replacement parts could create a safety hazard and
violate local regulations.

or leaking fuels cause vapors. Even filling customer tanks will
cause explosive vapors in the vicinity of dispenser or island.
