Astro Pneumatic Tool 78319 19-Piece 3/8" Drive 6-24mm Low Profile Nano Impact Socket Set

1. Introduction

This manual provides essential information for the safe and effective use of your Astro Pneumatic Tool 78319 19-Piece 3/8" Drive 6-24mm Low Profile Nano Impact Socket Set. Please read these instructions thoroughly before operation and retain for future reference.

2. Product Overview

The Astro Pneumatic Tool 78319 set includes 19 low-profile nano impact sockets, ranging from 6mm to 24mm, designed for 3/8" drive impact tools. These sockets are engineered for superior access in confined spaces.

Key Features:

• Full range 6-24mm set for 3/8" impact applications.
• Sockets are 0.88" (22.5mm) long, offering a significantly shorter profile than standard shallow impact sockets.
• Each socket features a 17mm outside hex for increased access when used with a wrench.
• Constructed from forged Chrome Molybdenum (CR-MO) steel for durability.

Included Components:

The set includes 19 individual 3/8" drive low profile nano impact sockets in sizes 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, and 24mm. These are typically supplied on a storage rail.

3. Setup

Before initial use, inspect all sockets for any signs of damage or manufacturing defects. Ensure the sockets are clean and free of debris. The sockets are designed to be used with a 3/8" drive impact wrench or ratchet.

1. Select the appropriate socket size (6mm to 24mm) for your fastener.
2. Ensure your impact tool or ratchet has a 3/8" square drive.
3. Firmly press the selected socket onto the square drive of your tool until it is securely seated.

4. Operating Instructions

These sockets are specifically designed for impact applications and for use in tight spaces where traditional sockets may not fit.

1. Attachment: Securely attach the chosen socket to your 3/8" drive impact wrench or ratchet.
2. Fastener Engagement: Place the socket squarely onto the fastener (nut or bolt head). Ensure full engagement to prevent stripping the fastener or damaging the socket.
3. Operation: Operate your impact tool or ratchet according to its manufacturer's instructions. The low-profile design allows for access in restricted areas.
4. Wrench Use: For extremely tight spots or when an impact tool is not feasible, the 17mm outside hex on each socket allows for use with a standard 17mm wrench, providing additional leverage and access.
5. Removal: After use, carefully remove the socket from the fastener and then from the drive tool.

5. Maintenance

Proper maintenance ensures the longevity and performance of your socket set.

• Cleaning: After each use, wipe down sockets with a clean cloth to remove dirt, grease, and debris. For stubborn grime, use a mild degreaser and dry thoroughly.
• Lubrication: Lightly oil the sockets periodically, especially if stored in humid conditions, to prevent rust.
• Storage: Store the sockets on the provided rail in a dry, clean environment to prevent loss and corrosion.
• Inspection: Regularly inspect sockets for wear, cracks, or deformation. Discontinue use of any damaged sockets to prevent injury or further damage to fasteners.

6. Troubleshooting

If you encounter issues during use, consider the following common solutions:

• Socket Not Fitting Fastener: Ensure you have selected the correct metric size (6-24mm) for your fastener. Verify the fastener is not stripped or damaged.
• Socket Not Attaching to Tool: Confirm your drive tool is a 3/8" square drive. Ensure the socket's drive end is clean and free of obstructions.
• Socket Slipping: Ensure the socket is fully seated on both the drive tool and the fastener. Avoid using worn or damaged sockets.
