Troubleshooting If the following troubles have occurred, check each check point. Power is not turned on. Trou- The power lamp on the operation panel does not light if the power switch is on. Check Point Solution Connect it to the machine and to the receptacle 1.
Troubleshooting The machine does not engrave finely. Trou- Engraved line width is unequal. Check Point Solution Fix the work firmly on the clamp table. 1. Is the work fixed on the clamp table firmly? P.3-3 Mount the chip removal attachment firmly. 2.
How to Install the Cutter Handle the cutter blade with care. The tip of the cutter blade is so sharp that could cut fingers. If the cutter blade is dropped down, the tip of the blade will be chipped and worsen the engraving quality.
How to Replace the Motor Brush How to Replace the Motor Brush Unplug the power cable before replacing the motor brush. If the cover of the motor brush is removed with the power on, the moving head could cause injury including cut of fingers or hands, or avulsion of nails. If the spindle rotates during replacing the motor brush, it could cause burn.
