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.

NOTE:
Do not tighten the collet chuck by inserting a shaft thinner than the regular shaft diameter (1/4’’ (6.35mm)) in the chuck or in an empty condition. This practice will damage the collet chuck.
When installing a wheel with shaft, tighten the collet chuck after applying a small quantity of spindle oil (or sewing machine oil) to the tapered portion indicated in Fig. 2.
7.Using the side handle (Fig. 4)
Be sure to use the side handle to avoid the risk of severe electrical shock.
Attach the side handle to the machine as follows.
(1)Loosen the side handle grip and insert the side handle to the nose bracket part of the machine from the flange part of the side handle sleeve.
(2)Set the side handle to a position that is suited to the operation and then securely tighten the side handle grip.

(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,
(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.
