English
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 de fl 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 e ffi ciency. Occasionally dress the wheel
by applying the dresser.
