Handle Operation
The handle on the Bird 4421 can be se
t to four different positions (see
Figure 6). To adjust the handle, press
the center buttons on both sides.
Releasing the buttons will lock the handle into position.
115/230V AC Input Power
The internal power supply
can operate at 115 VAC or 230 VAC. There is no
user setting to select the input volt
age because the power supply automati-
cally senses the input voltage. However,
you must make sure that you have
the correct power cord plug and fuses
installed for the line voltage you are
using (refer to Replacing Fuses, page 46).
AC Line Connectors
To make the ac line cord compatible wi
th non-U.S. voltages, users must install
the appropriate connector
on the power cord.
