2. Safety Information
Please read and understand all safety warnings and instructions before operating the device. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
- Keep Work Area Clean and Well Lit: Cluttered or dark areas invite accidents.
- Avoid Dangerous Environments: Do not use power tools in damp or wet locations, or where flammable liquids or gases are present.
- Stay Alert: Watch what you are doing and use common sense when operating a power tool. Do not use the tool while tired or under the influence of drugs, alcohol, or medication.
- Use Personal Protective Equipment: Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
- Secure Workpiece: Always clamp or otherwise secure the workpiece to a stable platform. Holding the workpiece by hand or against your body is unstable and may lead to loss of control.
- Do Not Overreach: Keep proper footing and balance at all times.
- Disconnect Power: Always disconnect the tool from the power source before making any adjustments, changing accessories, or storing the tool.
- Store Idle Tools: When not in use, tools should be stored in a dry, high, or locked-up place, out of reach of children.
- Maintain Tools with Care: Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.
- Check for Damaged Parts: Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function.
