Inspect and
lubricate shear
valves
Every six months
To check valve operation, perform the following tasks. If you are not sure
which device is the shear valve, have the ASC inspect and lubricate this
device for you.
Note: Shear valves are typically used only on dispensers. If you have
pumps, consult your installer to determine if they were installed on
your pump.
WARNING
The pump/dispenser contains pressurized flammable fuel and lethal voltages.
Servicing a Gasboy Atlas unit incorrectly could result in severe injury or
death.
Do
not
attempt to service the Gasboy Atlas pump/dispenser yourself, and do
not
allow untrained personnel to service Gasboy Atlas pumps/dispensers.
Only Gasboy Atlas-trained ASCs should service a Gasboy Atlas unit.

Self-contained pumps have a pinch point between the belts and the pulleys.
Severe injury could occur if part of the body is pulled into the pinch point.
To prevent injury while inspecting self-contained units, do not place your
hands near the belts, pulleys, or motors. Shut off power before servicing the
unit. Do not operate the unit with the door removed.
WARNING
Failure to shut off power to the unit before servicing could result in injury.
Failure to shut off power could create a hazard, such as electrical shock.
Shut off power to the unit before servicing it.
