7. Screw tightening torque
The screws used in this machine are largely classified into three
types.
These types are classified according to the shape of the screw
grooves and use positions.
The table below shows the types of the screws and the tightening
torques depending on the use position.
When tightening the screws for repair or maintenance, refer to the
table.
However, for the other conditions of tightening screws than speci-
fied on this table, or under special circumstances, the details are
described on the separate page. Refer to the descriptions on such
