3Machine installation 31Clearing the machine
Before the head is packed all ofthe parts of the machine are coated with anti-rust greasemeanwhile the grease can harden and the dust can cover the machine surface during long time storage and shipmentsothe dust and greasemust be cleared by clean cloth with gasoline
32Examination Although every machine is conformed by strict inspection and test before deliverythe parts ofthe
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 resis tance and abn-ormal noise If any of these existadjustment must be made accordingly before running
