Grinder Operation - Hitachi GP 2 Manual De Instrucciones

GRINDER OPERATION

1. Switching operation (Fig. 5)
(1) When throwing the switch lever to the ON side, power is applied; when throwing
it to the OFF side, power is switched off.
(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.
