Safety Warnings
General Power Tool Safety: Always keep the work area clean and well-lit. Do not operate in explosive atmospheres. Keep children and bystanders away. Ensure the power tool plug matches the outlet and do not modify it. Use personal protective equipment, including eye protection, dust masks, and hearing protection.
Grinding and Cutting-off Safety: This tool is intended for grinding or cut-off operations. Do not use accessories not specifically designed by the manufacturer. Ensure the rated speed of the accessory is at least equal to the maximum speed of the tool. Always use the provided guard and ensure it is securely attached. Do not use damaged accessories. Hold the tool by insulated gripping surfaces when performing operations where the cutting accessory may contact hidden wiring.
Kickback Warnings: Kickback is a sudden reaction to a pinched or snagged rotating wheel. Maintain a firm grip and position your body to resist kickback forces. Always use the auxiliary handle for maximum control.
Assembly and Operation
Fitting the Wheel Guard: Ensure the guard is securely attached and positioned for maximum safety. When using an abrasive cutting wheel, remove the standard wheel guard and attach the wheel guard with side guard (sold separately).
Mounting Wheels: Ensure the wheel is the correct type, free of cracks, and properly mounted with the correct flanges. Tighten the wheel nut securely.
Operation: Ensure the power switch is in the OFF position before connecting to the power source. The tool features a soft-start and 0-voltage re-start protection. If the 0-voltage re-start protection is activated, return the switch to OFF and wait at least 1 second before restarting.
Maintenance and Inspection
Carbon Brushes: The motor uses carbon brushes, which are consumable parts. Replace them when they reach or are near the wear limit. Keep brushes clean and ensure they slide freely in the holders.
Motor Maintenance: The motor winding is the heart of the tool. Ensure it does not become damaged or wet with oil or water.
Supply Cord: If the supply cord needs replacement, it must be done by a HiKOKI Authorized Service Center.
Technical Specifications
The tool is designed for a 230V power supply. It features a soft-start and 0-voltage re-start protection. Measured A-weighted sound power level is 101 dB (A), and sound pressure level is 90 dB (A). Vibration emission value for surface grinding is 5.3 m/s2.
