SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS
1. WARNING! Do not exceed the maximum 125 PSI storage pressure. Over
pressurizing the Air Tank could result in an explosion. Do not fill the Air Tank from
any compressed gas cylinder or a system charged with greater than 125 PSI.
Only fill the Air Tank with air from a service station or low pressure air compressor
system.
2. Do not leave the AirTank unattended while it is being filled by the air com-
pressor. Unattended use could result in an explosion, resulting in serious per-
sonal injury and/or property damage.
3. Do not fill the AirTank with any gas or other flammable substance under
any circumstances.
4. Burst hazard! Store the AirTank indoors. Do not expose the Air Tank to
moisture or excessive heat. Heat and humidity will contribute to corrosion of
the Tank (15). The Air Tank should be examined periodically. If the Tank shows
any evidence of dents, rust, gouges, bulges, or any damage to the welds is noted
the Air Tank should no longer be used.
5. It is recommended that you do not use the AirTank after the DESTROY
DATE shown on the bottom of theTank (15). Never puncture or set fire to an
Air Tank. Contact local solid waste authorities for instructions on correct disposal
or recycling of an Air Tank.
6. Pull the Safety Release Valve Ring (6) prior to operation to ensure the Valve
is operating properly and to clear the Valve of any obstructions.
7. When filling an object with air, beware of possible explosion. The Air Tank is
capable of producing compressed air at high pressure which could cause tires,
toys, or other inflatables to explode.
8. Before each use, always check all connections and joints on the AirTank to
make sure no air leaks are present. Check for air leaks by using soapy water.
9. Maintain a safe working environment. Keep the work area well lit. Make sure
there is adequate surrounding work space. Always keep the area free of obstruc-
tions, grease, oil, trash, and other debris. Do not use the Air Tank in areas near
flammable chemicals, dusts, and vapors.
10. Maintain labels and nameplates on the AirTank. These carry important infor-
mation. If unreadable or missing, contact Harbor Freight Tools for a replacement.

from the service station or low pressure air compressor. (See Figure B.)
Inflating From The Air Tank:
1. WARNING! Prior to inflating a toy, tire, or other object, make sure you are aware
of the proper air pressure rating (PSI) of the object to be inflated. Follow the
manufacturer’s recommended PSI for the object being inflated. Never over
inflate or under inflate the object.

to flow out of the Air Tank into the inflatable object. (See Figure B.)
4. Frequently check the air pressure of the inflatable object. To do so, close the
Air Outlet Knob (1.2) by turning it clockwise . Disconnect the Air Chuck of the Air
Hose (5) from the air inlet connector of the inflatable object. Use an air pressure
gauge (not included) to check the air pressure of the inflatable object.
(See Figure B.)
5. If necessary, repeat Steps #2, #3, #4 above until the inflatable object is filled with
air to its proper PSI rating.
6. When finished filling the inflatable object, close the Air Outlet Knob (1.2) by
turning it clockwise . Disconnect the Air Chuck of the Air Hose (5) from the air
inlet connector of the inflatable object. (See Figure B.)
