IMPORTANT SAFETY INFORMATION

General Safety Warnings

WARNING Read all safety warnings and instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible
conditions and situations that may occur. It must be understood by the operator that common sense
and caution are factors which cannot be built into this product, but must be supplied by the operator.

1. Work area safety

a. Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

b. Do not operate the Compressor in explosive

atmospheres, such as in the presence
of flammable liquids, gases or dust.

Compressor motors produce sparks
which may ignite the dust or fumes.

c. Keep children and bystanders away

from an operating compressor.

2. Electrical safety

a. A qualified electrician must connect the

compressor to a 240VAC/60Hz power
supply, rated to at least 25 amps.

b. Do not expose compressor to rain or wet

conditions. Water entering a compressor

will increase the risk of electric shock.

3. Personal safety

a. Stay alert, watch what you are doing and

use common sense when operating this
compressor. Do not use this compressor
while you are tired or under the influence
of drugs, alcohol or medication. A moment

of inattention while operating a compressor
may result in serious personal injury.

b. Use personal protective equipment.

Always wear ANSI-approved eye
protection during setup and use.

c. Prevent unintentional starting. Ensure the

switch is in the off-position before connecting
to power source or moving the compressor.

4. Compressor use and care

a. Do not use the compressor if the switch

does not turn it on and off. Any compressor
that cannot be controlled with the switch
is dangerous and must be repaired.

b. DISCONNECT and TAG OUT the

compressor’s power source, turn the
switch off, and relieve all air pressure
before making any adjustments, changing
accessories, or storing the compressor.

Such preventive safety measures reduce the
risk of starting the compressor accidentally.

c. Store an idle compressor out of 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.

d. Maintain the compressor. Keep the

compressor clean for better and safer
performance. Follow 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.

e. Use the compressor in accordance with

these instructions, taking into account
the working conditions and the work to
be performed. Use of the compressor for

operations different from those intended
could result in a hazardous situation.

5. Service

a. Have your compressor serviced by a

qualified repair person using only identical
replacement parts. This will ensure that the

safety of the compressor is maintained.

Air Compressor Safety Warnings

1. Risk of fire or explosion - do not spray

flammable liquid in a confined area or towards a
hot surface. Spray area must be well-ventilated.

SAFETY OPERATION MAINTENANCESETUP

Do not smoke while spraying or spray where
spark or flame is present. Arcing parts - keep
compressor at least 20 feet away from explosive
vapors, such as when spraying with a spray gun.

2. Risk of bursting - do not adjust regulator higher

than marked maximum pressure of attachment.

3. Risk of injury - do not direct air

stream at people or animals.

4. Do not use to supply breathing air.

5. Do not leave compressor unattended for an

extended period while connected to power
source. DISCONNECT and TAG OUT the
compressor’s power source, turn the switch
off, and relieve all air pressure after working.

6. Keep compressor well-ventilated.

Do not cover compressor during use.

7. Drain Tank daily and after use. Internal rust causes
tank failure and explosion.

8. Add correct amount of compressor oil before first
use and every use. Operating with low or no oil
causes permanent damage and voids warranty.

9. Do not remove the valve cover or
adjust internal components.

10. Compressor head gets hot during operation.
Do not touch it or allow children nearby
during or immediately following operation.

11. Do not use the air hose to move the compressor.

12. Release the pressure in the
storage tank before moving.

13. The use of accessories or attachments not
recommended by the manufacturer may
result in a risk of injury to persons.

14. All air line components, including hoses, pipe,
connectors, filters, etc., must be rated for a minimum
working pressure of 150 PSI, or 150% of the
maximum system pressure, whichever is greater.

15. Industrial applications must follow OSHA guidelines.

16. Maintain labels and nameplates on the
compressor. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.

17. This product is not a toy.
Keep it out of reach of children.

18. Operate unit on level surface. Check oil level
daily and fill to marked level if needed.

19. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.

contain lead, a chemical known to the State
of California to cause cancer and birth defects
or other reproductive harm. (California Health
& Safety Code § 25249.5, et seq.)

21. WARNING: The cord of this product contains
lead and/or di (2-ethylhexyl) phthalate (DEHP),
chemicals known to the State of California
to cause cancer, and birth defects or other
reproductive harm. Wash hands after handling.
