Stop using a tool that will not start, makes abnormal noise, overheats, vibrates excessively, runs at an unstable speed or has a damaged switch, cable or battery.

Safe checks

• Disconnect the power source before inspection.
• Check the disc, guard and mounting hardware for visible damage and correct installation.
• Use only the disc type and speed rating specified for the tool.
• Do not attempt live electrical repair or bypass protection devices.

When to seek professional repair

Internal electrical faults, repeated tripping, unusual heat, damaged cables or battery concerns require qualified service. This guide is general safety information, not a substitute for the model manual or trained repair personnel.
