side of the spindle box. Balance force shall be adjusted to the point that the spindle together
with its tool shall not go down itself when spindle stops. (go up a little bit shall be much
better).

8.2 Adjustment for the feed safety clutch:
Feed safety clutch is mounted on upper side of the warm shaft. If too much feed resisting force
is occurred, the feed safety clutch will be automatically slipped (sound “Ka” will be heard) in
order to protect machine driving system not to be damaged.
Clutch appearance could be seen when opening the cover below the feed change label.
Using a tool to turn a slotted nut in clockwise, this will increase the feed resisting force,
meanwhile, the counter clockwise will reduce the feed resisting force. The max. feed resisting
force of this machine is 7000N, Over feed resisting force will cause un-safety, be sure to lock it
by screw bolt or nut after adjustment.
