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 speed of turning spindle can be changed
through the belt pulley on the left end of the
machine.
The speed is 3 steps of 500, 900 and 1600 RPM.
Please refer to the speed plate on bedstock
cover on the left end of the machine
(shown in Fig.16).
Open the cover of turning spindle (Fig. 17). Loosen the motor fixing nut (Fig.18) to loosen the

Installing/Removing a Drilling/Milling Tool
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 taper hole of the drilling/milling spindle is Morse No.2 so, a drill, drill chuck, milling cutter,
and cutter chuck with Morse No.2 shank can be used, but tools with R8 shank cannot be used.
This machine is supplied with a Morse Taper No.2 shank (#8 in Fig. 1, Accessories) and a drill
chuck with key (#6), which can be directly installed on the taper hole of the drilling/milling
spindle.
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.
Installing/Removing Procedures
1. Insert the taper shank into the drill chuck as shown in Fig.19 and tighten with the chuck key.
2. Put the taper shank of chuck into the taper hole of spindle as in Fig. 20.
3. Pass the draw bar in the accessories (#7 in Fig. 1, Accessories) through the drilling/milling
spindle from the top (Fig. 20), and tighten it into the taper shank. Then, fasten the nut of the
draw bar with a wrench, as shown in Fig. 21.
4. When removing a tool from the drilling/milling spindle, lightly tap the draw bar downward with
a hammer (Fig. 22) to remove the chuck, or milling cutter. CAUTION: Wear gloves and be
ready to safely catch the chuck or milling cutter so it isn’t damaged.
