4. Setup

Proper setup ensures optimal performance and safety.

4.1 Air Supply Connection

1. Ensure the air compressor is off and the air line is depressurized.
2. Connect a 3/8-inch air hose (minimum recommended) to the air inlet of the ratchet. Use thread sealant tape on the air inlet threads for a secure, leak-free connection.
3. Connect the other end of the air hose to your air compressor's regulated output.
4. Set the air pressure regulator on your compressor to the recommended operating pressure (refer to Specifications section). Do not exceed 90 PSI (6.2 bar).
5. Turn on the air compressor and check for any air leaks.

4.2 Attaching Sockets

1. Select the appropriate inner socket size (8mm, 10mm, 11mm, 12mm, 13mm, or 14mm) for your application.
2. Slide the chosen inner socket onto the drive shaft of the ratchet. Ensure it seats fully and securely.
3. For standard square drive sockets, attach the 3/8-inch adaptor to the ratchet drive shaft first, then attach your square drive socket to the adaptor.

5. Operating Instructions

The SHINANO SI-1288 is designed for efficient fastening in tight spaces.

5.1 General Operation

1. Ensure the correct socket is securely attached to the ratchet.
2. Place the socket onto the fastener (nut or bolt head).
3. To tighten, ensure the directional switch (if present) is set for clockwise rotation. To loosen, set it for counter-clockwise rotation.
4. Press the trigger to activate the ratchet. Apply steady, controlled pressure.
5. Release the trigger once the fastener is tightened or loosened to the desired extent. Avoid over-tightening.

5.2 Thru-Hole Design Utilization

The unique thru-hole design allows the ratchet to be used with long bolts and studs, providing access where traditional ratchets cannot.

• When working with long fasteners, the bolt or stud can pass directly through the center of the inner socket and the ratchet head.
• This feature is particularly useful in applications such as engine work or machinery assembly where fasteners may extend significantly beyond the nut.

6.1 Lubrication

• Apply a few drops of pneumatic tool oil into the air inlet before each use, or at least once daily if used frequently.
• Run the tool for a few seconds after oiling to distribute the lubricant.

6.2 Cleaning and Storage

• Keep the tool clean and free of debris. Wipe down the exterior with a clean cloth.
