Operating the Tools
The TS18 kit provides a range of tools for common bicycle repairs. Familiarize yourself with each tool's function before use.
Multitool Usage:
The integrated multitool features various hex bits, Torx tools, and a flat screwdriver. To use, simply unfold the desired tool from the main body. Ensure the tool is fully extended and locked into place for safe and effective operation.
- Hex Bits: 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm - For adjusting bolts on components like stems, seatposts, and derailleurs.
- Torx Tools: T10, T25 - For specific Torx head bolts, commonly found on disc brakes and some component mounts.
- Flat Screwdriver: For various flat-head screws.
Tire Repair Tools:
- Tire Lever: Use to carefully pry the tire bead off the rim for tube access or tire replacement.
- Tire Plug Tool + Plugs: For repairing tubeless tire punctures. Insert a plug into the tool, push it into the puncture, and remove the tool, leaving the plug to seal the hole.
- Valve Core Tool: For removing and tightening Presta or Schrader valve cores, useful for adding sealant or replacing a faulty core.
- CO2 Head: Attach a CO2 cartridge (sold separately) to quickly inflate tires after repair. Follow CO2 cartridge instructions for safe use.
Chain Tool and Spoke Wrenches:
- Chain Tool: For breaking and rejoining bicycle chains. Ensure proper alignment and careful operation to avoid damaging the chain.
- Spoke Wrenches (0, 1, 2): For truing wheels by adjusting spoke tension. Use the correct size for your spokes.
Maintenance
Proper maintenance will extend the life of your TS18 Tube Stash Tool Kit and ensure its reliability.
- Cleaning: After use, especially in wet or dirty conditions, wipe down all tools with a clean, dry cloth. Remove any dirt or debris from the multitool pivots.
- Lubrication: Periodically apply a small amount of light lubricant to the pivots of the multitool to ensure smooth operation and prevent rust.
- Storage: Store the kit in a dry environment when not mounted on the bike. Ensure all tools are properly folded and secured within the bracket.
- Inspection: Regularly inspect the tools for any signs of wear, damage, or corrosion. Replace any damaged components immediately. Check the hook-and-loop strap for wear and ensure it still provides a secure hold.
Troubleshooting
Here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tools are stiff or difficult to unfold. | Dirt, rust, or lack of lubrication. | Clean the tool pivots and apply a light lubricant. |
| Items secured by strap are loose. | Strap not tightened sufficiently or strap wear. | Re-tighten the hook-and-loop strap. If worn, consider replacing the strap. |
| Tire plugs not sealing puncture. | Puncture too large, improper plug insertion, or old plugs. | Ensure plug is fully inserted and centered in puncture. For large punctures, a new inner tube may be required. Replace old plugs. |
