N ot e
: new lathes have very tight fitting jaws. This is neces-
sary to ensure accurate clamping and long service life. With
repeated opening and closing, the jaw adjusts automatically
and their operation becomes progressively smoother.
N ot e:
For the original 3-jaw chuck that mounted on the lathe, the
factory has mounted the chuck in the best way to Guarantee
the holding accuracy with two “0” mark (A, Fig.16) showed
on the chuck and chuck flange.
Three are two types of jaws: internal and external jaws.
Please note that the number of jaws fit with the number in-
side the chuck’s groove. Do not mix them together. When
you are going to mount them, please mount them in ascend-
ing order 1-2-3, when you are going to take them out, be
sure to take them out in descending order 3-2-1,one by one.
After you finished this procedure, rotate the jaws to the
smallest diameter and check that the three jaws are well
fitted.
