PUTTING INTO OPERATION

After performing the previous instruction, the machine is ready for operation,
the connection to the el. supply source is effected by the help of the main
interrupter. Turning on of the control lamp shows that the machine is
connected to the el. supply circuit.
All the speed within the range 75—1400 rpm (65—1810 rpm) at different
position of the levers are shown on Nameplate.
When starting the machine, check carefully whether all the gears are well
engaged
This is obtained by placing the handles at their fixed positions.
THE CHANGE-OVER OF THE GEARS SHALL BE EFFECTED ONLY
UNDER IDLING CONDITIONS.
The machine operating mode selection shall be realized from the speed
indication nameplate.
When trying the machine, put the speed change lever in low speed stage and
keep the machine running for at least 20 minutes, then gradually change the
speed of the spindle up to fastest, every stage running over 5 minutes.
CUTTING OF THREADS AND FEEDS
The feed box receives its motion from shaft V of the gearbox through a set of
change gears. If the handle 3 (Fig. 4. 5. 6) is placed in its r.h. position, the lathe
is set for cutting of r.h. thread. If the same handle is placed in its l.h. position,
the lathe is set for cutting of l.h. threading.
It is not required to place on the quadrant respective change gear set in order
to prepare the lathe for necessary feed.
The different values for feeds and threads are obtained by the different setting
of the quadrant and changing the position of drums / handle 4, 5, 6, 21 and
handle 3.
