- Position the Lever: Slide the shift/brake lever onto the handlebar. Position it ergonomically for comfortable reach of both the shift and brake levers.
- Secure the Lever: Use an appropriate hex key to tighten the clamp bolt. Do not overtighten; refer to torque specifications if available for your handlebar.
- Install Cables: The product includes an OT-SIS40 derailleur cable and housing set. Route the shift and brake cables through the appropriate guides on your bicycle frame.
- Connect to Derailleurs and Brakes: Connect the shift cables to the front and rear derailleurs and the brake cables to the front and rear brake calipers/mechanisms.

Operating Instructions
The EZ Fire Plus system allows for intuitive gear changes and reliable braking.
Shifting Gears:
- Upshifting (Higher Gear): Use the larger lever (typically operated by the thumb) to shift to a higher gear.
- Downshifting (Lower Gear): Use the smaller lever (typically operated by the index finger) to shift to a lower gear.
- Optical Gear Display: Observe the Optical Gear Display window to confirm your current gear position at a glance.
Braking:
- The integrated brake lever provides smooth and light action for effective stopping power.
- Apply pressure to the brake lever to engage the brakes. Apply both front and rear brakes simultaneously for controlled stopping.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your shift/brake levers.
- Cleaning: Keep the levers and surrounding areas clean from dirt and grime. Use a damp cloth and mild soap if necessary.
- Lubrication: Periodically lubricate the shift and brake cables to maintain smooth operation. Use a bicycle-specific lubricant.
- Cable Inspection: Regularly inspect shift and brake cables for fraying, kinks, or corrosion. Replace damaged cables promptly.
- Lever Function Check: Ensure both shift and brake levers move freely and return to their original positions without sticking.
- Bolt Tightness: Periodically check the tightness of the handlebar clamp bolts.
Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty shifting gears | Incorrect cable tension, dirty/frayed cables, misaligned derailleur | Adjust cable tension, clean/replace cables, adjust derailleur limits |
| Brakes feel spongy or weak | Loose brake cable, worn brake pads, contaminated braking surface | Tighten brake cable, replace brake pads, clean braking surface |
| Lever does not return smoothly | Lack of lubrication, internal dirt/debris, damaged spring | Lubricate pivot points, clean lever mechanism, consult a mechanic for repair |
