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

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

safety measures reduce the risk of

starting the compressor accidentally.

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.

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.

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.
