is packed, all the patis of the machine
are coated with preventive grease, meanwhile the hard-
ened grease and converged dust on the machine surface
during long storage and shipment must be removed by
clean cloth with gasoline.
(2) Examination
The parts of the machine may by loose and deformed
after long distance transportation with jolt though every
machine
is confirmed by strict inspection and test before
delive1y. A thorough examination must be performed
after cleaning the machine. Turn the balance wheel
to
check if there are running obstruction, patis collision,
uneven resistance
