electric shock.
Do not expose compressor to rainb.
or wet conditions. Water entering
a compressor will increase the risk
of electric shock.
Do not abuse the cord. Neverc.
use the cord for unplugging the
compressor. Keep cord away
from heat, oil, sharp edges
or moving parts. Damaged or
entangled cords increase the risk of
electric shock.
Personal safety3.
Stay alert, watch what you area.
doing and use common sense
when operating this compressor.
Do not use this compressor
while you are tired or under
the inuence of drugs, alcohol
or medication. A moment of
inattention while operating a
compressor may result in serious
personal injury.
Use personal protectiveb.
equipment. Always wear eye
protection. Safety equipment
such as a dust mask, non-skid
safety shoes, hard hat, or hearing
protection used for appropriate
conditions will reduce personal
injuries.
Prevent unintentional starting.c.
Ensure the switch is in the off-
position before connecting to
power source or moving the
compressor.
Only use safety equipmentd.
that has been approved by an
appropriate standards agency.
Unapproved safety equipment may
not provide adequate protection.
Eye protection must be ANSI-
approved and breathing protection
must be NIOSH-approved for the
specic hazards in the work area.
Compressor use and care4.
Do not use the compressor if thea.
switch does not turn it on and
off. Any compressor that cannot
be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from theb.
power source before making
any adjustments, changing
accessories, or storing the
compressor. Such preventive
safety measures reduce the risk of
starting the compressor accidentally.
Store an idle compressor out ofc.
the reach of children and do not
allow persons unfamiliar with the
compressor or these instructions
to operate it. A compressor is
dangerous in the hands of untrained
users.
Maintain the compressor. Keepd.
the compressor clean for better
and safer performance. Following
instructions for lubricating and
changing accessories. Keep
dry, clean and free from oil and
grease. Check for misalignment or
binding of moving parts, breakage
of parts and any other condition
that may affect the compressor’s
operation. If damaged, have the
compressor repaired before use.
Many accidents are caused by a
poorly maintained compressor.
Use the compressor ine.
accordance with these
instructions, taking into account
the working conditions and the
work to be performed. Use of the

must be rated for a minimum working
pressure of 150 PSI, or 150% of
the maximum system pressure,
whichever is greater.
USE OF AN EXTENSION CORD15.

GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM
INCORRECT GROUNDING
WIRE CONNECTION:
Check with a qualied
electrician if you are in doubt
as to whether the outlet is
properly grounded. Do not
modify the power cord plug
provided with the compressor.
Never remove the grounding
prong from the plug. Do not
use the compressor if the
power cord or plug is
damaged. If damaged, have it
repaired by a service facility
before use. If the plug will not
t the outlet, have a proper
outlet installed by a qualied
electrician.

In the event of a malfunction or1.
breakdown, grounding provides a
path of least resistance for electric
current to reduce the risk of electric
shock. This compressor is equipped
with an electric cord having an
equipment-grounding conductor and
a grounding plug. The plug must be

is properly installed and grounded in
accordance with all local codes and
ordinances.
Do not modify the plug provided –2.
if it will not t the outlet, have the

Improper connection of the3.
equipment-grounding conductor can
result in a risk of electric shock. The
conductor with insulation having
an outer surface that is green with
or without yellow stripes is the
equipment-grounding conductor. If
repair or replacement of the electric
cord or plug is necessary, do not
connect the equipment-grounding
conductor to a live terminal.
Check with a qualied electrician or 4.
service personnel if the grounding
instructions are not completely
understood, or if in doubt as to
whether the compressor is properly
grounded.
Use only 3-wire extension cords that5.

and well-lit. The work area must not
allow access by children or pets to
prevent injury.
Locate the Compressor on a at 2.
level surface to ensure proper pump
lubrication and to prevent damage to
the unit. Keep at least 12” of space
around the unit to allow air circulation.
Route the power cord from the3.
compressor to the grounded wall
outlet, along a safe path without
creating a tripping hazard or exposing
the power cord to possible damage.
Assembly
Attaching the Foot and Wheels
