Important Safety Information
This section introduces the hazards and safety precautions
associated with installing, inspecting, maintaining or servicing
this product. Before performing any task on this product, read
this safety information and the applicable sections in this
manual, where additional hazards and safety precautions for
your task will be found. Fire, explosion, electrical shock or
pressure release could occur and cause death or serious
injury if these safe service procedures are not followed.
Preliminary Precautions
You are working in a potentially dangerous environment of
flammable fuels, vapors, and high voltage or pressures. Only
trained or authorized individuals knowledgeable in the related
procedures should install, inspect, maintain or service this
equipment.
Important Safety Information
Read the Manual
Read, understand and follow this manual and any other
labels or related materials supplied with this equipment. If you
do not understand a procedure, call a Gasboy Authorized
Service Contractor or call the Gasboy Service Center at 1800-444-5529. It is imperative to your safety and the safety of
others to understand the procedures before beginning work.
Follow the Regulations
There is applicable information in NFPA 30A; Automotive and
Marine Service Code, NFPA 70; National Electrical Code (NEC),
OSHA regulations and federal, state, and local codes which
must be followed. Failure to install, inspect, maintain or
service this equipment in accordance with these codes,
regulations and standards may lead to legal citations with
penalties or affect the safe use and operation of the
equipment.
Emergency Total Electrical Shut-Off
The first and most important information you must know is
how to stop all fuel flow to the pump and island. Locate the
switch or circuit breakers that shut-off all power to all fueling
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.
Safety Symbols and Warning Words

Working With Fuels and Electrical Energy
Prevent Explosions and Fires
Fuels and their vapors will become explosive if ignited. Spilled
or leaking fuels cause vapors. Even filling customer tanks will
cause explosive vapors in the vicinity of dispenser or island.
Important Safety Information
No Open Flames
Open flames from matches, lighters, welding
torches or other sources can ignite fuels and their vapors.
No Sparks - No Smoking
Sparks from starting vehicles, starting or using power tools,
burning cigarettes, cigars or pipes can also ignite fuels and
their vapors. Static electricity, including an electrost atic
charge on your body, can cause a spark sufficient to ignite
fuels and their vapors. After getting out of a vehicle, touch the
metal of your vehicle to discharge any electrostatic charge
before you approach the dispenser island.
Working Alone
It is highly recommended that someone who is capable of
rendering first aid be present during servicing. Be familiar
with Cardiopulmonary Resuscitation (CPR) methods if you
are working with or around high voltages. This information is
available from the American Red Cross. Always advise the
station personnel about where you will be working, and
caution them not to activate power while you are working on
the equipment. Use the OSHA tag out and lock out
procedures. If you are not familiar with this requirement, refer
to information in the service manual and OSHA
documentation.
Working With Electricity Safely
Be sure to use safe and established practices in working with
electrical devices. Poorly wired devices may cause a fire,
explosion or electrical shock. Be sure grounding connections
are properly made. Make sure that sealing devices and
compounds are in place. Be sure not to pinch wires when
replacing covers. Follow OSHA Lock-Out and Tag-Out
requirements. Station employees and service contractors
need to understand and comply with this program completely
to ensure safety while the equipment is down.
Emergency First Aid
Informing Emergency Personnel

• Age of victim (for example, baby, teenager, middle-age,
elderly.)
• Whether or not victim has received first aid (for example,
stopped bleeding by pressure, and so on.)
• Whether or not a victim has vomited (for example, if
swallowed or inhaled something, and so on.)
