Caution
Mount the chuck firmly according to "How to mount" in this manual. Otherwise, the chuck might be loosened, which may eventually result in serious bodily injuries or accidents.
Check and confirm that the tool is clamped firmly by the three jaws before starting operation. Improper clamping of the tool will cause its abnormal run out, breakage and/or detaching, which may result in serious bodily injuries or accidents.
Tighten the chuck strongly by hands In case of chucking a tool of smaller diameter with a chuck of large capacity, the automatic tightening mechanism may fail to function properly, which may cause slipping of the tool and eventually its falling down.
The chuck can not be used to the CCW rotation. If the chuck is rotated in CCW direction, the tool will be loosened and spin off from the chuck which may cause serious bodily injuries or accidents.
The chuck can not be used to the machine having an emergency stop mechanism. If the machine spindle stops rotating by such emergency stopping, the tool will be loosened and spin off from the chuck, which may cause serious bodily injuries and accidents. (Use our CNC keyless chuck or dream chuck for the machines having such emergency stop mechanism.)
Do not touch the chuck or the tool while being rotated. Otherwise, there will be dangers to be caught by the rotating parts of the machine, which can result in serious bodily injuries or accidents.
Do not manipulate the chuck before complete stop of the spindle. Otherwise, there will be dangers to be caught by the rotating parts of the machine, which can result in serious bodily injuries or accidents.
Do not use the chuck if some abnormal conditions, like cracks, breakage or transformation are detected thereon. Use of such defective chuck may cause serious bodily injuries or accidents.
Do not make any repairing, re-assembling nor remodeling on the chuck. Use of such re-worked chuck may cause serious bodily injuries or accidents.
How to mount
1.The tapered part of the chuck must well be cleaned off of oily material, dust and foreign material.
2.The three jaws must be retracted below the level of the chuck nose.
3.The tapered part of the spindle or the arbor must also well be cleaned.
4.Insert the tapered part of the spindle or the arbor into the tapered part of the chuck, taking care not to make any flaws or damages on any of the tapered parts. And drive the chuck by hammering the edge of the soft steel bar with a wooden hammer, taking care not to let the chuck slip off or fall down from the spindle or the arbor.
5.Do not hammer the jaws nor sleeve.
