Installing/Removing Procedures
1. With a screwdriver, remove the screw on the flange (#9 in Fig. 1, Accessories), and then,
unscrew the flange as shown in Fig. 28. With an inner-hexagon L-key, fasten the flange on to
the spindle chuck (#2 in Accessories Fig. 1) tightly, as shown in Fig. 29, using the three set
screws provided (also #2 in Fig. 1).
2. Install the spindle chuck along with the flange on to the spindle (as shown in Fig. 30), then
refasten the pushing screw with a screwdriver.
3. Install the clamping jaws of the spindle chuck (Fig. 26 above and #2 in Fig. 1, Accessories):
a. Loosen the set screws of the clamping slots with the chuck key (Fig. 31 below and #12 in
Accessories Fig. 1) until the lead thread appears.
b. Put jaw No. 1 into jaw guide rails (Fig.32).
c. Turn the chuck key clockwise until the lead thread comes into view again (while watching the
counter-clockwise direction of the chuck).
d. Install jaws No.2 and No. 3 into the jaw guide rails in the same way.
4. Remove the clamping jaws by reversing the process in step 3 above.
5. When removing the spindle chuck by reversing steps 2 then 1, place a wooden cradle on the
rail below the chuck as a support (Fig. 34). DO NOT to catch the chuck with yours hands (Fig.
33), which can result in injury.
5. If using a taper shank with a flat end (Fig. 23), the shank can be directly inserted into the
taper hole of the spindle taking care that its flat end is aligned with the long slot in the
spindle.
When removing, move the quick-moving handle to lower the sliding sleeve until the long slot
comes out, then lock the sliding sleeve as shown in Fig. 24.
Put the tool-withdrawing wedge, included in the accessories (#5 in Fig. 1, Accessories), into
the long slot of the sliding sleeve, and lightly knock it with a hammer as shown in Fig. 25.
Take care to catch the taper shank so it does fall and get damaged.
Installing/Removing the Spindle Chuck
Put the power switches in the off positions before making any adjustments or changing
accessories. Such preventive safety measures reduce the risk of starting the machine
accidentally.
The spindle chuck is supplied with two sets of positive and negative clamping jaws on which 1,
2, and 3 are indicated (Fig. 26 below and #2 in Fig. 1, Accessories).
Each of the positive and negative clamping jaws of the spindle chuck has four ways to clamp a
workpiece, as shown in Fig. 27.
Note:
Before installing a chuck, center, connecting rod, or draw bar onto the spindles, or to the
mandrel of the tailstock, first wipe them with clean oilcloth. At the same time, clean the inside
surfaces of spindles with a long rod wrapped with oilcloth. Cutting chips and dust on the center
or on the top end of the spindle can scrape their surfaces and affect the linearity of their mating
pats.
