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
