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. 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 powered. Disconnect
power from compressor after working.
6. Keep compressor well-ventilated.
Do not cover compressor during use.
7. Do not remove the valve cover or
adjust internal components.
8. Do not use the air hose to move the compressor.
9. The use of accessories or attachments not
recommended by the manufacturer may
result in a risk of injury to persons.
10. 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.
11. Maintain labels and nameplates on the
compressor. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
12. This product is not a toy.
Keep it out of reach of children.
13. Wear ANSI-approved safety goggles and
heavy-duty work gloves during use.
14. Do not expose to rain or wet conditions.
15. 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.
16. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.
17. The battery Charger gets hot during
use. The Charger’s heat can build up to
unsafe levels and create a fire hazard if
it does not receive adequate ventilation,
due to an electrical fault, or if it is used in a
hot environment.
Do not place the Charger on a flammable surface.
Do not obstruct any vents on the Charger.
Especially avoid placing the charger on carpets
and rugs; they are not only flammable, but they
also obstruct vents under the charger.
Place the Charger on a stable, solid, nonflammable
surface (such as a stable metal workbench or
concrete floor) at least 1 foot away from all
flammable objects, such as drapes or walls. Keep a
fire extinguisher and a smoke detector in the area.
Frequently monitor the Charger and
Battery Pack while charging.
18. 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.

Battery tool use and care
1. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to battery pack, picking up or carrying the
power tool. Carrying the power tool with your
finger on the switch or energizing power tool
that have the switch on invites accidents.
2. Disconnect the battery pack from the power
tool before making any adjustments, changing
accessories, or storing power tool. Such
preventive safety measures reduce the risk
of starting the power tool accidentally.
3. Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of
fire when used with another battery pack.
4. Use power tools only with specifically designated
battery packs. Use of any other battery
packs may create a risk of injury and fire.
5. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
6. Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
7. Do not use a battery pack or power tool that is
damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
8. Do not expose a battery pack or power tool to
fire or excessive temperature. Exposure to fire or
temperature above 265°F may cause explosion.
9. Follow all charging instructions and do not charge
the battery pack or power tool outside of the
temperature range specified in the instructions.
Charging improperly or at temperatures
outside of the specified range may damage
the battery and increase the risk of fire.
10. Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that
the safety of the product is maintained.
11. Do not modify or attempt to repair the power
tool or the battery pack except as indicated
in the instructions for use and care.
