Here are a few more tips and reminders for when using your Dremel 8200 rotary tool. Knowing these should make your efforts easier, safer, and more productive.
1. Always use the collet size that matches the shank size of the accessory you are using. There are 4 different collet sizes (1/32″, 1/16″, 3/32″ and 1/8″) available for the Dremel 8200. The 1/8″ size collet is normally included on most tool sets.
2. The 8200 comes with a built-in “hanger” that you can use to hang your rotary tool when not in use. When you need to use your Dremel 8200, simply snap the hanger back into place on the body of the rotary tool.
3. Make sure your attached accessory is balanced on your rotary tool before using it. After connecting your accessory, simply turn on the rotary tool and you should be able to tell by feel and sound if the connected accessory is balanced. To correct an imbalance, simply loosen the collar nut, rotate the accessory a bit, and retighten the collar nut. Then recheck the balance by restarting the rotary tool. You may need to go through these steps a couple of times until you are satisfied with the balance. The Dremel 8200 comes with a collet wrench.
4. When using wire brushes, never set the operating speed of the rotary tool above 15,000 RPM. Pieces of the wire brush can become loose during the operation and become embedded in your skin. Also, when you first connect a wire brush to your Dremel, turn the Dremel on and let it run for about a minute before using it. This 60 second heating period should shake out any loose pieces of wire in the brush.
5. When using your depth grinding tool or when using a cut-off wheel, hold the body of the Dremel like a fishing rod: with your thumb on top near the ON/OFF switch, the body of the Dremel the tool resting in the palm of the hand and the other four fingers securing the left side of the tool.
6. Setting your rotary tool to a speed greater than 15,000 RPM when using a bristle brush can damage the brush.
7. When working with plastic, turn your tool on a low speed and gradually increase the speed until you see the plastic begin to melt. Then slow down your tool a bit. This will give you the optimum working speed for that piece of plastic.
8. If all 3 lights on the fuel gauge begin to flash “off and on”, this indicates that your rotary tool battery has become too hot for use. Just turn off your tool, take a break, and let your tool cool down. (Note: If all 3 lights are flashing “side to side” or only 1 light is flashing “off and on”, that means the battery needs to be recharged.)
9. As with most cutting tools, never turn your Dremel on when touching the material you are going to work on. Instead, turn your Dremel on and let it reach the maximum speed you set before you start cutting/polishing/sanding/grinding/etc. the material.
10. If the bit on your tool binds in the material you’re working on, don’t worry. Your Dremel’s motor will stop automatically (a nice feature). Once you can disengage the bit from the material tool, the rotary tool will start again automatically.
I hope these tips and reminders help you!
