Arctic Cat 400 - LCD Gauge (400)

43
Control engine RPM with the position of
the throttle lever. Operate this lever with
the thumb. Pushing it forward increases
engine RPM and allowing it to retract
decreases engine RPM.
Throttle Limiter Screw
ATV-0053
Throttle lever travel may be limited by
adjusting the throttle limiter screw. The
throttle limiter should be adjusted
according to the operator’s skill and
experience. To adjust the throttle limiter,
use the following procedure.
1. Loosen the jam nut.
2. Turn the throttle limiter screw clock-
wise to decrease engine RPM maxi-
mum or counterclockwise to
increase engine RPM maximum.
3. Tighten the jam nut securely.
 NOTE: The ATV is equipped with
an RPM limiter that retards ignition
timing when maximum RPM is
approached. When the RPM limiter
is activated, it could be misinter-
preted as a high-speed misfire.

1. Clock/Engine Hour Meter - The
clock function indicates time in the
12-hour mode; the hour meter indi-
cates the total time the ATV has run
and cannot be reset to zero. To set
the clock, use the following proce-
dure.
A. With the ignition switch ON,
press and release the Mode But-
ton (3) until the Clock/Engine
Hour Meter (1) is displayed; then
(if necessary) press and release
the Set/Reset Button (4) to select
the clock display.
B. Press and hold the Set/Reset But-
ton (4) until the minutes stop
scrolling and the hour display starts
to scroll. Momentarily release
when the correct hour is displayed;
then repeatedly press and release
the Set/Reset Button (4) until the
correct minutes are displayed.
 NOTE: Clock memory power is
supplied through the 15-amp acces-
sory fuse and verified during gauge
“power-up” and reset. In the event
of clock memory power failure
(blown fuse, etc.), the gauge will
“power-up,” reset, and shut down
repeatedly until clock memory
power is restored. Always check the
15-amp accessory fuse if this
gauge condition is noted.
 NOTE: The engine hour meter will
not activate until engine speed
exceeds 500 RPM.
2. Temperature Indicator - If the engine
coolant temperature exceeds the normal
operating range, the temperature icon
will begin flashing and the LCD will go
blank for 30 seconds; then the LCD will
return to normal. However, the temper-
ature icon will continue to flash.
CAUTION
Continued operation with high engine
temperature may result in engine
damage or premature wear.
