Need help?Do you have a question about the Stanley FATMAX SFMCM300 and is the answer not in the manual?
This document describes the STANLEY FATMAX 18V Cordless Cutoff Tool SFMCM300, a professional-grade tool designed for cutting various materials.
The SFMCM300 is a cordless cutoff tool intended for professional cutting applications. It is designed to cut different materials, with specific cutting blades recommended for various applications. The tool features a variable speed trigger for controlled operation, a forward/reverse/lock-off button to select the direction of rotation and lock the tool in an off position, and an LED worklight to illuminate the immediate work surface. It is equipped with a rotatable guard for safety and a shoe that can be adjusted for depth of cut, providing stability when cutting on flat surfaces. The tool also includes a dust port adaptor for connecting to an external dust extractor, which helps manage dust and debris during operation.
Battery and Charging: The tool operates on 18V Li-Ion battery packs. To install, align the battery pack with the rails in the tool's handle and slide it in until it locks. To remove, press the battery release button and pull the pack out. Fuel gauge battery packs (if equipped) show the charge level via three green LED lights when the fuel gauge button is pressed. The battery pack should be fully charged before first use for maximum performance and life. Charging should only be done with STANLEY FATMAX specified chargers, within a temperature range of 4 °C to 40 °C.
Wheel Installation and Adjustment: The tool uses wheels no greater than 3" (76 mm) in diameter, with an inner diameter of 3/8" or 7/16" (if using an adaptor ring), and a maximum thickness of 0.09" (2.2 mm). Wheels must not have cutting teeth. To install a wheel, remove the battery pack, lay the unit with the spindle facing upward, hold the spindle lock button, and use the supplied hex wrench to remove the spindle screw and outer flange. Ensure the inner flange is in place, slip the wheel over the spindle (matching rotation direction for diamond wheels), then slip on the outer flange with the flat side towards the wheel. Thread the spindle screw counterclockwise, depress the spindle lock button, and tighten the screw with the hex wrench. Always ensure the wheel is properly centered and does not hit the shoe, guard, or spindle screw.
Guard Adjustment: The rotatable guard angle can be adjusted to provide maximum control and protection. Remove the battery pack, grasp the guard firmly, and rotate it until it snaps into one of three secure positions. The guard must always be used with all cutting wheels.
Depth of Cut Adjustment: The shoe, which comes pre-assembled, can be removed or mounted. To adjust the depth of cut, loosen the depth adjustment knob and slide the shoe up or down until less than 1/4" of the wheel is visible below the workpiece. Tighten the knob after adjustment. The shoe is recommended for stability when cutting on flat surfaces.
Operation: The tool is turned on by depressing the variable speed trigger, with speed increasing as the trigger is depressed further. The forward/reverse/lock-off button allows selection of cutting direction (counterclockwise for forward, clockwise for reverse) or locking the tool in the off position. For best control, the user's cutting direction should be opposite to the wheel's rotation. Always ensure the wheel is at full speed before continuing a cut. Feed the wheel into the workpiece slowly with firm, even pressure. Do not force the tool, as this can cause kickback. When cutting, keep the shoe against the workpiece and maintain a firm grip. Release the trigger to stop the tool.
Cutting Tips:
Safety Precautions: Always wear personal protective equipment, including eye protection, dust mask, hearing protectors, gloves, and a shop apron. Maintain a firm grip on the tool and use the auxiliary handle (if provided) to resist kickback forces. Never place hands near the rotating accessory or position the body in line with the rotating wheel. Avoid bouncing and snagging the accessory, especially in corners or sharp edges. Do not "jam" the wheel or apply excessive pressure. If the wheel binds, switch off the tool and hold it motionless until it stops completely before attempting to remove it. Do not restart cutting in the workpiece; let the wheel reach full speed first.
General Maintenance: The power tool is designed for long-term operation with minimal maintenance. Regular cleaning and proper tool care are essential for satisfactory performance.
Cleaning: Before cleaning, disconnect the electrical appliance from the power source. Always keep the electrical appliance and ventilation slots clean. Do not use solvents or harsh chemicals on non-metallic parts. Use a cloth dampened with water and mild soap. Never immerse the tool in liquid or allow liquid inside. Ventilation slots can be cleaned with a dry, soft non-metallic brush or a vacuum cleaner. Wear approved eye protection and a dust mask during cleaning.
Lubrication: The power tool requires no additional lubrication.
Charger and Battery Pack Maintenance: Chargers and battery packs are not serviceable. If the supply cord of the charger is damaged, it must be replaced by STANLEY FATMAX or an authorized service organization. Do not attempt to charge faulty battery packs.
Storage: During transportation and storage, lock the variable speed trigger with the lock-off button and remove the battery pack. Store the battery pack in a cool, dry place away from direct sunlight, excessive heat, or cold for optimum performance and life. For long storage, it is recommended to store a fully charged battery pack in a cool, dry place out of the charger. Do not store battery packs completely depleted of charge.
Belt Hook (Optional Accessory): An optional belt hook (sold separately) can be attached to the accessory attachment location at the base of the tool using the provided screw. This allows the tool to be hung from a work belt. Ensure the screw is securely tightened.
Environmental Protection: Products and batteries marked with the crossed-out wheeled bin symbol must not be disposed of with normal household waste. They contain materials that can be recovered or recycled. Recycle electrical products and batteries according to local provisions. Li-Ion cells are recyclable and should be taken to a dealer or local recycling station.
