Warning and Caution Statements and General Safety Guidelines
Warning statements indicate a particularly dangerous activity. Warning statements you will find in
this manual include:
•
To remove power from the EFX, the power cord must be disconnected from the wall outlet.
Always ensure that the EFX is unplugged from the wall outlet when you inspect or adjust the
EFX, or when you isolate, remove, or replace an EFX component.
•
Removing the covers exposes high voltage components and potentially dangerous
machinery. Exercise extreme caution when you perform maintenance procedures with the
hood removed.
•
During service operations you will be very close to moving machinery and high voltage
components. When you perform maintenance procedures with the covers removed, remove
jewelry (especially from ears and neck), tie up long hair, remove neck ties, and do not wear
loose clothing.
•
Exercise caution when touching any wire or electrical component during EFX operation.
•
A pinching hazard exists when the unit is operated by turning the crankarms by hand. It is
possible to seriously pinch a finger between the crankarm and stairarm. The stairarms
should be removed before operating the crankarms by hand.
