Safety Information

Read all safety warnings and all instructions. Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
Risk of electric shock. Do not expose power tool to rain or wet conditions.
Keep work area clean and well-lit. Cluttered or dark areas invite accidents.
Do not operate power tool in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

Do not operate power tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tool may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Dust mask, non-skid footwear, hard hat, hearing protection, and gloves are recommended.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.
Remove adjusting keys or wrenches before turning the power tool on. A wrench or key left attached to a rotating part of the tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts.
