IMPORTANT SAFETY INSTRUCTIONS

INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS
WARNING – When using air tanks, basic precautions should always be followed, including the following:

General Safety
1. To reduce the risks of explosion and injury to persons, read all the instructions before using the air tank.
2. The warnings and precautions discussed in this 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 that cannot be built into this product but must be supplied by the operator.
For technical questions, please call 1-888-866-5797. Item 65594 65595
Pressurized Tank Handling Safety
PRESSURIZED TANKS CAN EXPLODE WHEN DAMAGED.

1. Protect pressurized or closed tanks from heat, being struck, physical damage, flames, and sparks.
2. Always use proper procedures to move pressurized tanks.

Personal Safety
1. Stay alert. Watch what you are doing and use common sense when filling or using the air tank. Do not fill or use the air tank while tired or under the influence of drugs, alcohol, or medication.
2. Always wear eye protection. Wear ANSI-approved safety goggles.
3. Always wear hearing protection when using the air tank. Prolonged exposure to high-intensity noise is able to cause hearing loss.

Use Safety
1. Keep the air tank when it is full out of reach of children and other untrained persons. A air tank is dangerous in the hands of untrained users.
2. Check for breakage of parts and any other condition that affects the air tank’s operation. If damaged, have the air tank serviced before using. Many accidents are caused by poorly maintained air tanks. There is a risk of bursting if the air tank is damaged.

Service
1. Air tank service must be performed only by qualified repair personnel.
2. When servicing a air tank, use only identical replacement parts. Use only authorized parts.
3. Maintain the air tank with care.
4. Safely discharge all air pressure from the air tank before storing the air tank.

Air Source

1. Never connect to an air source that is capable of exceeding  200 psi. Over pressurizing the air tank may cause bursting, abnormal operation, breakage of the air tank, or serious injury to persons. Use only clean, dry, regulated compressed air at the rated pressure or within the rated pressure range as marked on the air tank. Always verify prior to filling the air tank that the air source has been adjusted to the rated air pressure or within the rated air-pressure range.
2. Never use oxygen, carbon dioxide, combustible gases or any bottled gas as an air source for the air tank. Such gases are capable of explosion and serious injury to persons.
3. Obey the manual for the air compressor used to power this air tank.

SAVE THESE INSTRUCTIONS.

Specifications

Operation

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document including all text under subheadings therein before set up or use of this product.
Note : For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram near the end of this manual.

Filling the Tank

1. Take your Air Tank to any source of clean and dry compressed air. A full- service gas station or truck stop is preferable.
2. Attach air hose from the service station or low-pressure Air Compressor system to the air fitting on the Manifold (4).
3. Begin pumping air into the Air Tank.
NOTE : Monitor the Pressure Gauge (3) as you fill the Air Tank. Fill as needed. WARNING! TO PREVENT SERIOUS INJURY: Do not overfill the tank.

Releasing Air From Tank
1. Turn the round On/Off Wheel (5) counterclockwise to the open position. This allows air to flow from the Air Tank (1) through the Air  Hose (2).
2. Next place Outlet Valve at the end of the Air Hose (2) over the valve of the object to be inflated.
3. Once the pin inside the Outlet Valve is depressed, air will begin to flow out from the Air Tank into the object being inflated. Once you are finished inflating air into the object, remove the Outlet Valve and the air will stop being released from tank.
Warning! Do not overinflate. Do not exceed the maximum pressure rating of any inflatable object. Check pressure frequently during inflation. The Air Tank should be examined periodically. If any damage to the welds is noted do not use the tank.

Inflating
1. Press the Air Chuck (7) onto the fill stem of the inflatable item.
2. Turn the red Adjustment Dial (6) counterclockwise to ON. This will let the airflow from the Tank and into the Hose (3).
DO NOT OVER-INFLATE.
3. Once the item is filled with the recommended max. PSI level, remove the Air Chuck from the item’s fill stem.
Note : The Tank pressure must exceed the pressure of the item you are illing. If not, the Tank will be unable to expel air. If this happens, increase the Tank pressure and check that the ON/OFF Adjustment Dial is fully open.
WARNING! Never ill the tank to over 125 PSI. 4. When done, turn Adjustment Dial to OFF. This will close the valve between the Tank and Hose and keep air from leaking.
5. It the Tank will not be used for long period of time, expel air inside Tank and hose. Store in clean and dry location away from children.

Maintenance

1. Regularly drain water condensation from of Tank, which can lead to internal corrosion and damage to the tank. To drain, hold Tank upside down and remove the Bypass Valve Spring (2).
2. Due to internal corrosion, do not use the tank beyond the destroy date stamped into the leg of the Tank (1). Safely disable the tank as follows:
a. Depressurize the air tank completely, by holding the Bypass Valve Spring open.
WARNING! Failure to properly depressurize the tank before proceeding may result in serious personal injury.
b. Remove the pressure gauge and hose.
c. Deliver the tank to a pressure tank disposal service, if available.
d. If a pressure tank disposal service is not available, place the tank in a secure, stable working location and drill at least two 1/2″ (or larger)  holes through the side of the tank. Then, deliver to the appropriate recycling center.
Storing the Air Tank
1. Turn the round On/Off Wheel (5) clockwise to the Off position. This will keep air from leaking out of Air Hose.
2. Store in a dry, dust-free location away from children and any flammable materials.
3. To remove all air from the Air Tank, pull the Ring (13) until the Gauge indicates zero and the airflow stops.
WARNING! If there is any question about a condition being safe or unsafe, do not operate the tool.
