  • Always wear eye protection. Use appropriate personal protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection.
  • Stay alert, watch what you are doing, and use common sense when operating a power tool.
  • Prevent unintentional starting. Ensure the switch is in the off-position before connecting to battery pack, picking up or carrying the tool.

Power Tool Use and Care:

  • Do not force the power tool. Use the correct power tool for your application.
  • Do not use the power tool if the switch does not turn it on and off.
  • Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
  • Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.

3. Setup Instructions

3.1. Battery Charging

  1. Connect the STANLEY FatMax V20 Rapid Charger to a standard power outlet.
  2. Slide the V20 Lithium-Ion Battery into the charger until it clicks into place.
  3. Observe the indicator lights on the charger. A solid green light typically indicates a full charge.
  4. Once fully charged, remove the battery from the charger.

Note: Always charge batteries in a well-ventilated area and avoid extreme temperatures.

3.2. Battery Installation and Removal

  1. To install: Align the battery with the tool's battery port and slide it in until it locks securely.
  2. To remove: Press the battery release button (usually located on the battery itself or the tool) and slide the battery out.

3.3. Attaching Accessories (General Guidelines)

Always ensure the battery is removed from the tool before attaching or changing accessories.

  • Rotary Hammer (SFMCH900): Insert SDS Plus drill bits directly into the chuck until they click. Rotate to ensure it's locked. To remove, pull back the chuck collar and pull out the bit. Attach the side handle by rotating it onto the tool's collar and tightening.
  • Angle Grinder (SFMCG400): Press the spindle lock button. Use the provided wrench to loosen the flange nut. Place the grinding or cutting disc onto the spindle, ensuring it's correctly seated. Tighten the flange nut securely. Adjust the guard for optimal protection. Attach the side handle into one of the threaded holes.
  • Percussion Drill (SFMCD711): Open the keyless chuck jaws by rotating the front collar. Insert the drill bit into the chuck. Tighten the chuck by hand until the bit is secure. For stubborn bits, use the chuck key if provided, or grip firmly and twist.
  • Impact Driver (SFMCF800): Pull back the collar of the hexagonal chuck. Insert the 1/4" hex shank bit. Release the collar to lock the bit in place. Pull on the bit to ensure it is securely fastened.

4. Operating Instructions

Before operating any tool, ensure you have read the safety information and the battery is fully charged and correctly installed.

4.1. STANLEY FatMax SFMCH900 Rotary Hammer

  • Mode Selection: Use the mode selector switch to choose between drilling (rotation only), hammer drilling (rotation with percussion), or chiseling (percussion only, for light breaking work).
  • Starting the Tool: Press the trigger switch. The speed is variable depending on trigger pressure.
  • Operation: Apply firm, steady pressure. Allow the tool to do the work. Do not force it. For hammer drilling, ensure the bit is sharp and suitable for the material.

4.2. STANLEY FatMax SFMCG400 Angle Grinder

  • Starting the Tool: Press the trigger switch. Some models may have a lock-on button for continuous operation.
  • Operation: Hold the grinder firmly with both hands. Position the disc at a slight angle to the workpiece for grinding. For cutting, use the edge of the disc and maintain a straight line. Always direct sparks away from yourself and others.
  • Safety: Ensure the guard is correctly positioned. Never use a damaged or incorrect disc.

4.3. STANLEY FatMax SFMCD711 Percussion Drill

  • Mode Selection: Use the selector switch to choose between drilling (for wood, metal, plastic) and hammer drilling (for masonry).
  • Torque Settings: Adjust the torque collar to the desired setting. Lower settings are for driving screws, higher settings for drilling. The drill setting bypasses the clutch for maximum power.
  • Speed Selection: Use the gear selector switch (usually 1 or 2) for low speed/high torque or high speed/low torque.
  • Starting the Tool: Press the trigger switch. Speed is variable.
  • Operation: Apply steady pressure. For hammer drilling, allow the percussion action to work.

4.4. STANLEY FatMax SFMCF800 Impact Driver

  • Starting the Tool: Press the trigger switch. The speed is variable based on trigger pressure.
  • Operation: Position the bit firmly into the screw head. Apply forward pressure and press the trigger. The impact mechanism will engage automatically when resistance is met, driving the fastener efficiently.
  • Reverse: Use the forward/reverse selector switch to change rotation direction for removing screws.
