Specific Safety

WARNING! DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to the tool safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose.
2. Do not use the tool if any parts are damaged, broken, or misplaced. Repair or replace the parts.
3. Ensure the inflator's vents are not blocked during operation.
4. Do not operate the inflator to result in output pressure greater than the marked maximum pressure of the item to be inflated. Do not use at pressure greater than 110 PSI.
5. Make sure the hose is free of obstructions or snags. Entangled or snarled hoses can cause loss of balance or footing and may become damaged.
6. Never leave an inflator unattended with the air hose attached to the item being inflated. Always disconnect the air supply and power supply before making adjustments, servicing an inflator, or when an inflator is not in use.
7. Attach all accessories properly to the tool. A loose accessory may detach or break during operation.

Air Hose Precautions

1. Inspect the tool's air hose for cracks, fraying, or other faults before each use. Discontinue use if the air hose is damaged or hissing is heard from the air hose or couplers. Replace the defective air hose.
2. Do not allow people, mobile equipment, or vehicles to pass over the unprotected air hose. Position the air hose away from high traffic areas, in a reinforced conduit, or place planks on both sides of the air hose to create a protective trench.
3. Prevent damage to the air hose by observing the following:
   • Never carry the tool by the air hose.
   • Keep the air hose behind the tool and out of the tool's work path.
   • Keep the air hose away from heat, oil, sharp edges, or moving parts.
   • Do not wrap the air hose around the tool as sharp edges may pierce or crack the air hose. Gently coil the hose and either hang on a hook or fasten with a device to keep the hose together when storing.
4. A damaged or disconnected air hose under pressure may whip around and inflict personal injury or damage the work area. Secure the compressor's air hose to a fixed or permanent structure with clamps or cable ties.

Air Tool Precautions

1. Use only clean and dry compressed air as a power source. Contaminated or moist air will gradually damage the tool.
2. Install an in-line shutoff valve or regulator to allow immediate control over the air supply in an emergency, even if a hose is ruptured.
3. Discontinue tool use if it does not work properly or air is leaking. Tag or mark the tool as 'defective' or 'out of service' until repaired.
4. Check the manufacturer's maximum pressure rating for air tools and accessories. Compressor outlet pressure must be regulated to never exceed the maximum pressure rating of the tool (see Specifications). Exceeding the maximum PSI rating can create a bursting hazard, causing injury and property damage.
5. Attach all accessories properly to the tool before connecting the air supply. A loose accessory may detach or break during operation.
6. Never use oxygen, combustible gas, or any other bottled gas as a power source. Any power source other than an air compressor could cause an explosion and serious personal injury.
7. Turn OFF the valve and discharge any remaining air pressure after each use or before adjusting the tool.
8. Do not leave the air tool unattended with its compressed air supply on. Turn off the compressed air supply and bleed the air tool of any remaining compressed air before leaving the air tool unattended.
9. Serious injury may occur from loose debris being propelled at high speeds from the compressed air stream. Always wear OSHA approved safety glasses to protect the eyes during operation of the air compressor.
10. Always turn off the air compressor and drain tank pressure completely before attempting maintenance or attaching air tools. Release pressure slowly from the system.

Assembly & Installation

Install Air Coupler Plug

Prepare a standard 1/4 in. NPT coupler plug for use with your tool.

1. Wrap the external threads of the coupler plug with sealant tape.
   • Wrap tape in a clockwise direction so it will not unravel.
   • Do not tape all the threads. Leave several leading threads unwrapped for easier alignment.
2. Screw the coupler plug into the tool's air inlet and tighten with a wrench until snug.
3. Run the compressor at a low volume and check the connection for air leaks. Do not use the tool until all air leaks are repaired or the faulty component is replaced.

IMPORTANT! Vibration may cause failure if a quick coupler is connected directly to the air tool. To overcome this, connect a leader hose to the tool. A quick coupler may then be used to connect the leader hose to the air line hose.

Operations

The tire inflator will automatically show the tire pressure once it is attached to the tire's stem.

1. Attach the air hose from the air source to the inflator's air coupler plug.
2. Replace the air chuck with an inflator adapter when required. Unscrew the air chuck from the hose and screw in the appropriate adapter until snug.
3. Press the light switch to turn on the LED light if the work area is dark. Press the button again to turn the light off.
4. Place the chuck on the valve stem and push it down so that the threaded section is inside the air chuck.
5. Press the power switch to the ON position to activate the digital gauge. The LED will automatically light up when the tire inflator is active.
6. Select the air flow unit type on the LCD screen. Press the unit button multiple times until the correct pressure scale appears.
7. Squeeze the trigger to allow the air to flow. The airflow rate is increased by squeezing the trigger tighter.
8. Watch the pressure gauge until the inflated object reaches the desired pressure.
   • The pressure gauge is not calibrated and is for approximation only. Use a separate calibrated pressure gauge if precision is required.
   • Inflate smaller items that require 10 PSI or less in bursts to avoid rupturing them.
9. Release the trigger when inflation is complete.
10. Press the deflator valve button to release excess pressure from the tire or inflatable.
11. Shut off the air source if there are no other items to inflate.
12. Press the power switch to the OFF position to turn off the digital gauge.
13. Press and hold the unit button for 3 to 5 seconds to turn the gauge off.
14. Disconnect the air chuck from the tire stem.

Inflator Adapters

Some adapters can be screwed directly into the air chuck. Other adapters must be screwed into the Presta Valve adapter and then the Presta Valve adapter is attached to the air chuck.

• Presta Valve Adapter: Screw the Presta Valve adapter onto the Schrader valve tire stem until snug. It is ready for inflation.
• Pinch Valve Adapter: Remove the inflatable toy's valve plug. Press the inflatable toy adapter into the pinch valve. Hold in place while inflating. Pull the adapter from the valve and push the valve plug back into place.
• Needle Adapter: Insert the needle adapter into the valve on the ball or smaller inflatable toy. Hold in place while inflating. Remove the needle from the valve when completed.

4-Way Valve Repair Tool

A damaged valve core may prevent a tire from maintaining air pressure. The 4-way valve repair tool is designed to remove and insert Schrader valve cores and rethread the internal and external threads.

1. Remove the valve cap and set aside.
2. Fit the notched tool extension over the valve core. The notch aligns with two raised ridges.
3. Turn counterclockwise to unscrew the tire valve core. Pull the core free of the stem.
4. Switch to the flat-end tap extension and insert it into the stem. Gently turn the tool counterclockwise to find the threads, then turn clockwise to realign and correct the internal threads. Unthread the tap by turning counterclockwise.
5. Switch to the narrow reamer. Insert into the valve stem and turn several times while holding the stem opening downward. Pull the reamer from the stem to remove any debris that may block the stem opening.
6. Place the external tap over the stem valve threads. Gently turn the tool counterclockwise to find the threads, then turn clockwise to realign and correct the external threads. Unthread the tap by turning counterclockwise.
7. Place a new tire valve core into the valve stem, with the valve pin upright.
8. Fit the notched tool extension over the valve core and turn clockwise until the valve is snug. Unscrew to remove the tool.
9. Screw the valve cap back into place.
