1.Clearing the machine
Before the head is packed, all of the parts of the machine are coated with anti-rust grease, meanwhile
the grease can harden and the dust can cover the machine surface during long time storage and shipment, so,
the dust and grease must be cleared by clean cloth with gasoline.
2.Examination
Although every machine is conformed by strict inspection and test before delivery, the parts of the machine
may be loose and deformed after long distance transportation with jolt. A thorough examination must be performed.
Turn the balance wheel slightly by hand to check if there is running obstruction, parts collision, uneven resistance
and abnormal noise. If any of these exist, adjustment must be made accordingly before running.
