2. Setup
Your Roco mechanical pencils come pre-loaded with HB lead. To load or replace lead:
- Locate the eraser at the top of the pencil.
- Gently pull the eraser and the attached mechanism straight out from the pencil body. This will reveal the lead reservoir.
- Insert new 0.5 mm lead sticks into the reservoir. Do not overfill; typically, 2-3 lead sticks are sufficient.
- Carefully push the eraser and mechanism back into the pencil body until it is securely seated.

3. Operating Instructions
Using your Roco mechanical pencil is straightforward:
- To extend the lead, press the top button (where the eraser is located) repeatedly until the desired lead length is exposed.
- To retract the lead, press and hold the top button, then gently push the lead back into the tip.
- The eraser can be used by removing the cap or by simply using the exposed part.
4. Maintenance
Proper maintenance ensures the longevity and smooth operation of your mechanical pencils:
- Cleaning the Tip: If lead dust accumulates in the tip, gently remove it using a soft brush or a piece of cloth. Avoid using sharp objects that could damage the mechanism.
- Lead Storage: Store extra lead in a secure container to prevent breakage.
- Avoid Drops: Dropping the pencil, especially on its tip, can damage the internal mechanism or bend the lead sleeve, leading to lead breakage or jamming.
- Eraser Replacement: When the eraser wears down, it can be replaced by pulling out the old one and inserting a new compatible eraser.
5. Troubleshooting
Here are solutions to common issues you might encounter:
- Lead Not Advancing:
- Check if the lead reservoir is empty. Load new lead if necessary.
- Ensure the lead is the correct 0.5 mm diameter. Incorrect lead size can cause jamming.
- Inspect the tip for broken lead pieces or debris. Clear any obstructions carefully.
- Lead Breaking Frequently:
- Avoid extending too much lead at once. A short extension provides better support.
- Apply less pressure when writing.
- Ensure you are using good quality 0.5 mm HB lead.
- Eraser Not Staying In:
- Ensure the eraser is fully pushed into the mechanism.
- If the eraser is old or worn, it might have shrunk. Replace it with a new one.
