(2)After installing a new wheel, "test" the condition of the wheel by allowing the grinder to operate for 180 seconds while the wheel is pointed away from you. Keep your hands and body away from the wheel at all times.

2. Precautions on operation

(1)Lightly press the wheel to the material to be ground when grinding materials, high-speed revolution is necessary. Use a hand grinder with high-speed revolution, minimizing the pressing force.

(2)Dressing the wheel

After attaching a wheel, adjust deflection of the wheel center by using a dresser. If the wheel center is eccentric, not only precise finishing cannot be achieved but also grinder vibration increases, lowering grinder accuracy and durability. A clogged or worn wheel will soil the finishing surface or lower grinding efficiency. Occasionally dress the wheel by applying the dresser.
