Router Saftey Tips:

• Always wear eye and ear protection.
• Always use properly sharpened bits.
• Never use bits that are dull or damaged.
• Shank must be completely inserted into collet and then backed-off approximately 1/16".
• Don't "bottom-out" bit in collet.
• Never partially insert bit into collet. Tighten securely and recheck periodically for possible slippage or "run-out" due to wear.
• Keep collet clean and replace if worn.
• Never start the router with the bit in contact with wood.
• Always feed your work in the proper direction against the bit rotation.
• Don't force feed the bit or overload your router, Feed at a constant moving speed to avoid burning the wood.
• Do not face tool's discharge when operating.
• Always unplug router when changing bits or making adjustments.
• Use a router table and fence whenever possible.
• Make sure your work piece is properly secured and use push blocks, sticks and featherboards whenever possible.
• Keep all your bits, bearings and assemblies clean, lubricated, and securely fastened. To avoid damage, store them properly in a pouch, box or tray.
• The bigger the bit, the lower RPM recommended (see chart).
