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.
If the power switch needs to be left on when
carrying out some adjustment, be extremely
careful to observe all safety precautions.
If any safety devices have been removed,
be absolutely sure to re-install them to their
original positions and check that they
operate correctly before using the machine.
