Setup and Bit Installation
For 8-in-1 HVAC Slide Drive Tool (Model 32596)
- Selecting a Bit: Identify the required bit from the included selection (1/4-Inch and 3/8-Inch hollow nut drivers, #2 Phillips, 1/8-Inch (3 mm) and 1/4-Inch (6 mm) slotted screwdriver tips, TR-4 Schrader).
- Inserting Bits: Push the desired bit firmly into the magnetic tip of the shaft. The magnetic tip will hold the bit securely.

- Inserting Bits: Select the required bit and insert it into the hex opening at the end of the blade. Ensure it is fully seated.
- Adjusting Blade Length: The blade is adjustable. Pull the blade out to extend it for longer reach or push it in for compact use. The blade locks into position.

Operating Instructions
General Use
- Always select the correct bit or nut driver size for the fastener to prevent damage to the fastener or the tool.
- Apply firm, steady pressure while turning to prevent cam-out.
- Ensure the bit is fully engaged with the fastener head before applying torque.
Specific Applications
- HVAC Tasks: Both tools are ideal for HVAC applications, including working with Schrader valves, thermostat adjustments, and panel fastening.
- Tight Spaces: The adjustable blade of the 14-in-1 screwdriver allows for shorter configurations, making it suitable for confined areas.
- Impact Driving (14-in-1 only): The 14-in-1 Adjustable Screwdriver is impact-rated. It can be used as an attachment with an impact driver for high-torque applications. Ensure the blade is securely locked in place when used with an impact driver.
Maintenance
- Cleaning: Wipe down the tools with a clean, dry cloth after each use to remove dirt, grease, and debris. For stubborn grime, a mild detergent solution can be used, followed by thorough drying.
- Storage: Store tools in a dry environment to prevent rust. Keep bits organized within their respective tools to avoid loss.
- Inspection: Periodically inspect bits and nut drivers for wear or damage. Replace worn bits to maintain optimal performance and prevent fastener damage.
- Magnetic Tip: The magnetic tip on the 8-in-1 tool may collect metallic dust. Clean it regularly to maintain magnetic strength.
Troubleshooting
- Bit Slipping: Ensure the correct bit size is used for the fastener. Check the bit for wear; replace if necessary. For the 8-in-1, ensure the thumb nut is tightened to lock the tip.
- Difficulty Changing Bits/Sizes (8-in-1): Ensure the SlideDrive™ mechanism is clean and free of debris. Apply a small amount of light lubricant if movement is stiff.
- Blade Not Locking (14-in-1): Check for debris in the blade release mechanism. Ensure the blade is fully inserted or extended until it clicks into place.
- Bits Falling Out of Handle (14-in-1): Ensure the blade is fully inserted into the handle to secure the bit carousel.
