Standard Accessories; Specifications; Mounting And Operation - Hitachi GP 2S2 Handling Instructions Manual

Wheels can be simply attached and detached by using
the two wrenches. (Fig. 2)
○ Do not tighten the collet chuck by inserting a shaft thinner
than the regular shaft diameter (6 mm) 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.
5. Be sure to use the side handle to avoid the risk of severe
electrical shock.
6. 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.
7. Dressing the wheel
After attaching a wheel, correct defl ection of the wheel
center by using a dresser. If the wheel center is eccentric,
not only precise fi nishing cannot be achieved but also
grinder vibration increases, lowering grinder accuracy
and durability.
A clogged or worn wheel will spoil the fi nishing surface or
lower grinding effi ciency. Occasionally dress the wheel
by applying the dresser.
