5) Always be sure the tool holder or accessory is locat ed correctly on the spindl e
taper and it is securely pulled to the face of the spindle.
6) Be sure any i tem bolted or clamped to a vise or fixture is securely fastened
before starting the spindle.
7) Proper lifting equipmen t should be used for heavy vise s, fixtures, and work
pieces.
8) Always be aware of that closing vise’s jaws may trap fingers or hands.
9) The same safety instructions that apply to power vise s also apply to manu al
operated vise s. The following additional precautions should be taken when using
a manual vise :
A. Always use spring -loaded, self -ejecting type safety wrenches.
B. Never put an extension bar on a vise wrench or hit with hammer.
C. Always slightly tap the workp iece after clamping with the jaws. This is
done to make sure workpiece is securely tightened to the vise. Without
confirming the tightness, the workpiece may fly out of the vise if the
cutting force is too greater!
10) If a work piece is extended from the vise a distance of 3 to 4 times of its
capacity, without being supported by other means , poor cutting finish will normally
occur. Under no circumsta nces extend an unsupported work piece more than this
amount witho ut supporting with other devices . Doing so c an cause the part to bend
or break or flying out!
