Jump to the sectionProduct Overview
The HiKOKI G 10SS2, G 12SS2, and G 13SS2 are professional-grade disc grinders designed for removing casting fins, finishing various steel, bronze, and aluminum materials, and grinding welded sections. These tools are powered by a 600W motor and are intended for grinding operations only.
Safety Precautions
Warning: Failure to follow safety instructions can lead to electric shock, fire, or serious injury. Always wear eye protection and use appropriate personal protective equipment (dust mask, gloves, hearing protection). Ensure the work area is clean, well-lit, and free of flammable materials. Do not use the tool in explosive atmospheres.
Operation
Before starting, ensure the power source matches the tool's nameplate specifications. Always verify the switch is in the OFF position before plugging in. The wheel guard must be securely fitted and adjusted to protect the operator from wheel fragments. When grinding, maintain an angle of 15°–30° between the wheel and the workpiece. Do not apply excessive pressure; the weight of the machine is generally sufficient for effective grinding. After switching off, wait for the wheel to come to a complete stop before setting the tool down.
Maintenance
Regularly inspect the grinding wheel for cracks or defects. Check that all mounting screws are tight. Carbon brush inspection and replacement, as well as power cord repairs, must only be performed by a HiKOKI Authorized Service Center to ensure safety. Keep air vents clear of dust to prevent motor overheating.
