(also see the chart on the front bottom side of the apron).
3. Oil brand and oil replace time: Use Shell Tellus T-68 and replace the oil once every six months.
4. To adjust the half nut engagement lever: After using the lathe a long time, the lever may be
loosened and needed to be adjusted. First, take off the thread chasing dial and find the four gib
adjustment screws. Second, while pressing the lever, also adjust the four gib adjustment screws
until they are properly tightened. Afterwards, replace the thread chasing dial to original
position.
5. To clean up and repair the manual pump being blocked or when it has small oil flow: If no oil
oozes out after pushing the manual pump several times, the pump is blocked. Take off the four set
screws of the pump body and loosen the plug lever to dismantle the cover nut. Use air gun to
clean up the inside of the blocked pump. If the oil flow is too small, the O-ring must have been
worn out, please replace with a new O-ring and assemble back the dismantled parts accordingly.
6. Adjustment for the longitudinal & cross auto feeding overload: The cone clutch on the center
of the apron is an overload device. The safety overload weight limitation is 12 Kg. Overload weight
can be adjusted by means of the Hexagon screw on the center of the apron; tighten clockwise,
the overload will increase; unscrew counter-clockwise, the overload will loosen. When auto-
feeding, hold the handwheel tightly by hand, it should automatically disengage if the overload is
set at 12Kg. If not, adjust the tension again.
