SAFETY NOTES
PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID
POSSIBLE EXPOSURE TO EXCESSIVE DANGER AND ELECTRICAL SHOCK:
1. Disconnect electrical supply before servicing machine.
2. If electricity is required for a test:
(A) First, disconnect electrical supply;
(B) Second, make any connections
or adjustments required for the test;
(C) Third, connect electrical supply;
(D) Fourth,
perform the test. If service is required, disconnect electrical
supply before servicing machine.
3. Please use caution when servicing the machine with the front panel
removed because there is danger of injury due to potential contact
with spinning transmission.
4. Please use caution when servicing the machine with the front panel
removed because
there is danger of injury due to contact with a
potential"pinch point" between the turned up edge of the transmission
cover and the tub support flange.
