Grounding Instructions; Extension Cords - Porter-Cable US58 Instruction Manual

1. Ensure regulated pressure gauge reads 0 PSI.
2. Pull coupler on Quick Connect body back to release Quick
Connect plug on hose.

Grounding Instructions

WARNING: Risk of electrical shock. In the event of a short circuit,
grounding reduces the risk of shock by providing an escape wire for
the electric current. This air compressor must be properly grounded.
The portable air compressor is equipped with a cord having a
grounding wire with an appropriate grounding plug.
1. The cord set and plug (J) with this unit
contains a grounding pin (L). This plug
MUsT be used with a grounded outlet
(K).
IMpOrTAnT: The outlet being used must
be installed and grounded in accordance
with all local codes and ordinances.
2. Ensure the outlet being used has the same configuration as the
grounded plug. DO NOT USE AN ADAPTER.
3. Inspect the plug and cord before each use. Do not use if there
are signs of damage.
4. If these grounding instructions are not completely understood, or
if in doubt as to whether the compressor is properly grounded,
have the installation checked by a qualified electrician.
DANGER: Risk of electrical shock. IMPROPER GROUNDING
CAN RESULT IN ELECTRICAL SHOCK.
• Do not modify the plug provided. If it does not fit the available
outlet, a correct outlet should be installed by a qualified electri-
cian.
• Repairs to the cord set or plug MUST be made by a qualified
electrician.

Extension Cords

If an extension cord must be used, be sure it is:
• a 3­wire extension cord that has a 3­blade grounding plug, and
a 3-slot receptacle that will accept the plug on the product
• in good condition
• no longer than 50 feet
• 16 gauge (AWG) or larger. (Wire size increases as gauge
number decreases. 14, 12, 10, and 8 AWG may also be used.
NOTICE: Risk of Property Damage. The use of an undersized exten-
sion cord will cause voltage to drop resulting in power loss to the
motor and overheating. Instead of using an extension cord, increase
the working reach of the air hose by attaching another length of
J
hose to its end. Attach additional lengths of hose as needed.

Voltage and Circuit Protection
Refer to the Voltage and Minimum Branch Circuit Requirements under
Pump/Motor Specifications.
L
CAUTION: Certain air compressors can be operated on a
15 amp circuit if the following conditions are met.
• Voltage supply to circuit must comply with the National Electrical
Code.
• Circuit is not used to supply any other electrical needs.
• Extension cords comply with specifications.
• Circuit is equipped with a 15 amp circuit breaker or 15 amp
time delay fuse. nOTE: If compressor is connected to a circuit
protected by fuses, use only time delay fuses. Time delay fuses
should be marked "D" in Canada and "T" in the US.
Compatibility
Air tools and accessories that are run off the compressor must be
compatible with petroleum-based products. If you suspect that a
