User Manual

With an electronic engine, the fan may also
be activated by air intake temperature, oil
temperature and compression brake
usage.
WARNING
DO NOT work on or near the fan with
the
engine running. Anyone near the
engine fan when it turns on could be
injured. If it is set at MANUAL, the fan
will turn on any time the ignition key
switch is turned to the ON position. In
AUTO, it could engage suddenly with-
out warning. Before turning on the igni-
tion or switching from AUTO to MAN-
UAL, be sure no workers are near the
fan. Failure to comply may result in
death or personal injury.
CAUTION
The fan or equipment near it could be
damaged
if the fan turns on suddenly
when you do not expect it. Keep all
tools and equipment away from the
fan.
CAUTION
DO NOT operate the engine fan in the
MANUAL
position for extended peri-
ods of time. The fan hub was designed
for intermittent operation. Sustained
operation will shorten the fan hub’s
service life as well as reduce fuel
economy.
