ELECTRICAL GROUNDING INSTRUCTIONS:
This product should be electrically grounded. In the event of an electrical short circuit, grounding reduces the
risk of electrical shock by providing an escape wire for electrical current. This product is equipped with a cord
having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is
properly installed and grounded in accordance with all local codes and ordinances.
DANGER: IMPROPER INSTALLATION OF THE GROUNDING PLUG CAN RESULT IN A
RISK OF ELECTRIC SHOCK. If a repair or replacement cord is necessary, do not connect
the grounding wire to either flat blade terminal. Check with a qualified electrician or
serviceman, if the grounding instructions are not completely understood or if there is doubt
as to whether this product is properly grounded. Do not modify the plug provided. If the
supplied plug does not fit the outlet, have the proper outlet installed by a qualified electrician.
This product is shipped for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug
in sketch A. A temporary adapter that looks like the adapter illustrated in sketches B and C may be used to
connect this plug to a 2-pole receptacle as shown in sketch B, if a properly grounded outlet is not available.
The temporary adapter should be used only until a properly grounded outlet (sketch A) can be installed by a
qualified electrician. The green colored rigid ear, lug, or like extending from the adapter must be connected to
a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be
held in place by a metal screw.
The motor of this compressor has a thermal overload protector in the motor winding. If the motor should
overheat, the overload protector will shut the motor off. When the temperature returns to normal, the motor will
restart automatically.
NOTICE! Do not stop the compressor by pulling out the plug. Use only the On/Off switch, which operates a
pressure relief valve on the compressor. If the compressor is plugged in with the switch in the “ON” position,
the compressor may have trouble restarting against the high pressure which could cause excessive heat build
up and could damage the motor.
Safety Valve:
This compressor is equipped with a safety valve that is set to avoid over-pressurization of the air tanks. This
valve is factory pre-set at 140 PSI and will not function unless tank pressure reaches this pressure. DO NOT
ATTEMPT TO ADJUST OR ELIMINATE THIS SAFETY DEVICE. ANY ADJUSTMENTS TO THIS VALVE
COULD CAUSE SERIOUS INJURY.
If this device requires service or maintenance, see an Authorized
BOSTITCH Service Center.
