If installed incorrectly:

* The disc may wobble during use.
* It may not sit flat against the flange.
* You risk uneven wear or even disc breakage.

#### 2. **Proper Tool Engagement**

Some grinders use a locking nut with a shaped or raised edge that matches the outer (flat) surface of the disc. The printed side often serves as the **contact point** for that lock nut. If you flip it, you may:

* Damage the disc.
* Risk it slipping while in use.
* Compromise cutting/grinding efficiency.

#### 3. **Safety and Performance**

Incorrect disc installation can cause:

* **Reduced control**
* **Excessive vibration**
* **Cracking or shattering** of the disc under stress

With the picture side facing out, you’re using the disc the way it was intended — maximizing safety and ensuring it performs at peak efficiency.

### ⚠️ **What Happens If You Install It Backwards?**

If you mistakenly mount the disc with the label facing inward:

* The disc might not lock securely.
* You may experience inconsistent grinding or cutting.
* The disc may wear unevenly or shatter due to improper load distribution.
* You void any safety ratings or warranties.

### 🛠️ **Tips for Safe Grinder Disc Use**

* Always **check the label** for RPM rating — and ensure it matches or exceeds your grinder’s speed.
* Use the **correct disc type** for the job (cutting, grinding, sanding, etc.).
* Never use a **cracked or damaged disc** — it can explode at high speeds.
* Wear **full PPE**: gloves, goggles, face shield, and ear protection.
* Let the tool do the work — don’t force the grinder.

### ✅ **The Bottom Line**

Always install your grinder discs **with the picture side (label side) facing up/out**. It’s not just a matter of preference — it’s a matter of safety, proper tool operation, and getting the job done right. Taking a few seconds to install the disc correctly can save you from poor performance, tool damage, or serious injury.

So next time you’re gearing up for a cut or grind, remember: **Label up. Safety first.**
