Applies to: All Cutting Machines

It is not recommended. The machine should use TOAUTO-approved cutting blades. Damage or hazards caused by non-original blades are the user’s responsibility. The blade center bore must also match the extended rotor, and if the mismatch exceeds 0.5 mm / 0.02 in, the blade must not be used.

Applies to: All Cutting Machines

The machine supports 0–5000 RPM speed adjustment through the smart terminal controller and 360° precision rotary adjustment.

Applies to: All Cutting Machines

For general safety and cutting quality, the manual recommends operating within 1500–3000 RPM. Speeds above 3500 RPM are not recommended unless necessary, and 4500–5000 RPM is considered a hazardous cutting range.

Applies to: All Cutting Machines

Standard Mode / S Mode adjusts speed by ±200 RPM per knob rotation.

Fine Mode / F Mode adjusts speed by ±50 RPM per knob rotation, which is better for valuable, delicate, or speed-sensitive materials.

Applies to: All Cutting Machines

Before operation, check that the blade is firmly fastened, the coolant level is sufficient, any assisted cutting mechanism is properly adjusted and locked, and the operator is wearing safety goggles, protective clothing, and a dust mask.

Applies to: All Cutting Machines

The startup process is: add coolant, connect power, turn on the hydraulic circuit breaker, press the machine’s one-touch start/stop switch, connect the smart terminal controller with the Type-C cable, power on the controller, select Standard Mode or Fine Mode, then adjust speed using the 360° precision dial.

Applies to: All Cutting Machines

Reduce speed to 0 RPM, power off the smart terminal controller, power off the main cutting machine, and switch off the hydraulic circuit breaker to fully disconnect the power.

Applies to: All Cutting Machines
