STANLEY FATMAX SBH900M2K-B1 20V Cordless Brushless Rotary Hammer Instruction Manual

1. Important Safety Instructions

Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

General Power Tool Safety Warnings

• Work Area Safety: Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not operate power tools 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.
• Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
• Personal Safety: Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

Rotary Hammer Specific Safety Warnings

• Wear ear protectors. Exposure to noise can cause hearing loss.
• Use auxiliary handles supplied with the tool. Loss of control can result in personal injury.
• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and could give the operator an electric shock.
• Always wear safety glasses or eye protection.

The rotary hammer features three operating modes:

• Rotary Drilling (Drill Mode): For drilling in wood, metal, plastics, and other materials that do not require hammer action.
• Hammer Drilling (Hammer Drill Mode): For drilling in concrete, masonry, and stone. This mode combines rotation with hammer action.
• Chiseling (Chisel Mode): For light chiseling, chipping, and demolition work in concrete and masonry. The rotation is disengaged, allowing only hammer action.

To select a mode, rotate the mode selector dial to the desired icon. Ensure the tool is switched off before changing modes.
