Maintenance and inspection
Maintenance and inspection of the sewing machine should only be carried out by a qualified
technician.
Any problem in machine operation which result from unauthorized modifications to the machine
will not be covered by the warranty.
Turn off the power switch and disconnect the power cord from the wall outlet at following times,
otherwise the machine may operate if the treadle is depressed by mistake, which could result in
injury. 1. when carrying out inspection, adjustment and maintenance. 2. when replacing consumable
parts such as the rotary hook.
If the power switch needs to be left on when carrying out some adjustment, be extremely careful to
observe all safety precautions.
Use both hands to hold the machine head when tilting it back or returning it to its original position. If
only one hand is used, the weight of the machine head may cause your hand to slip, and your hand
may get caught.
Ask your GLOBAL dealer or a qualified electrician to carry out any maintenance and inspection of
the electrical system.
If any safety devices have been removed, be absolutely sure to reinstall them to their original
positions and check that they operate correctly before using the machine.
Use only the proper replacement parts as specified by GLOBAL
