4. Disconnect Power
Always remember to disconnect the power source itself before changing blades or bits on your power tools. In addition to ensuring the switch is off, make sure there is no electricity being powered to the tool, since the switch can malfunction and/or accidentally get turned on.
5. Use A Single Extension Cord
Using one heavy duty extension cord for all your power tools will ensure that you switch off the power for each tool. Too many cords can get confusing and be a tripping hazard.
6. Never Use Blunt Blades & Bits
While this might seem obvious seeing as how dangerous a dull cutting tool can be. Dull tools will need to be made to work harder to cut and as a result can bind or kick back. Sharp bits and blades will ensure cleaner cuts as well.
7. Check Stock for Existing Metal
Before sawing through or making a cut, ensure that the piece of stock doesn’t have existing nails, screws or other pieces of metal lodged into it already. Spinning blades and nails (and other pieces of metal) don’t mix well together causing damage to both the stock and the cutting head. It can also cause stock to kick back and cause injury, so always ensure (or use a metal detector to ensure for you) that the stock is clean.
