Key Features

• Dual Ratcheting Heads: Features 17mm and 22mm ratcheting ends, specifically designed to lock onto and retain Astro's 3/8" and 1/2" drive low-profile Nano impact sockets.
• 100-Tooth Flex-Head Design: Provides fine ratcheting action with minimal swing arc, allowing access in extremely confined areas. The flex-head pivots 180 degrees for versatile positioning.
• Ultra Low-Profile: Maintains a total thickness of 0.9" to 1.1" with a socket attached, enabling work in tight spaces where standard wrenches cannot reach.
• Overall Length: Measures 11.8 inches, offering a balance of reach and maneuverability.
• Compatibility: Works with Astro 78310, 78314, 78211, 78215, and other socket sets featuring 17mm or 22mm outside hex dimensions.

Safety Information

Always observe the following safety precautions when using hand tools:

• Wear appropriate personal protective equipment, such as safety glasses, to prevent eye injury.
• Ensure the tool and workpiece are stable before applying force.
• Do not use the wrench if it is damaged or appears to be malfunctioning.
• Avoid using extension handles or "cheater bars" as this can overload the wrench and cause damage or injury.
• Keep hands and fingers clear of moving parts and pinch points.
• Store the tool in a clean, dry place away from children.

Setup

Attaching Nano Sockets

1. Select the appropriate Nano impact socket (3/8" or 1/2" drive) for your application.
2. Identify the corresponding wrench head (17mm for 3/8" drive Nano sockets, 22mm for 1/2" drive Nano sockets).
3. Align the Nano socket with the hexagonal opening on the wrench head.
4. Firmly press the socket into the wrench head until it clicks into place. The internal spring clip mechanism will retain the socket.
5. Gently pull on the socket to ensure it is securely attached before use.

Operating Instructions

Using the Ratcheting Mechanism

• The wrench features a 100-tooth ratcheting mechanism on both ends, allowing for fine adjustments and minimal handle swing.
• To change the direction of the ratcheting action (tightening or loosening), simply flip the wrench over. The wrench is designed to operate in both directions by reversing its orientation.

Utilizing the Flex-Head

• The flex-head design allows the wrench head to pivot up to 180 degrees. This feature is crucial for accessing fasteners in awkward or obstructed locations.
• Adjust the angle of the head by gently bending it to the desired position. The internal friction mechanism will hold the head in place during use.

Maintenance

• Cleaning: After each use, wipe the wrench clean with a dry cloth to remove dirt, grease, and debris. For stubborn grime, a mild solvent or degreaser can be used, followed by thorough drying.
• Lubrication: Periodically apply a small amount of light machine oil to the ratcheting mechanisms and flex-head pivot points to ensure smooth operation and prevent corrosion. Avoid over-lubrication.
• Storage: Store the wrench in a dry environment to prevent rust. A tool roll or drawer organizer is recommended to protect the polished finish and prevent damage.
• Inspection: Regularly inspect the wrench for any signs of wear, damage, or deformation. Discontinue use if any issues are found and consider replacement.

Troubleshooting

Socket not retaining securely:

Ensure the socket is fully seated and clicked into place. Inspect the internal spring clip mechanism for any obstructions or damage. If damaged, the wrench may require replacement.

Ratcheting mechanism feels stiff or gritty:

Clean the ratcheting head thoroughly and apply a small amount of light machine oil. Operate the mechanism back and forth to distribute the lubricant. If the issue persists, internal components may be worn.

Flex-head does not hold position:

The friction mechanism in the flex-head may be worn. This can occur over extended use. If the head cannot maintain its angle, the tool's effectiveness in tight spaces will be reduced.
