CAUTION

Wedging forces in the bushing saw slot, such as that exerted by a narrow edged
regular screw driver, may damage or break the bushing. This damage would not
be covered under the GSI warranty.

Do not lubricate the bushing taper, bushing bore, hub taper or the shaft. Doing so
could result in breakage of the product.

Do not use worn hex key wrenches. Doing so may result in a loose assembly or
may damage the screws.
