
NOTE: A disabled ECT system WILL NOT cause
engine damage; however, a failed ECT system will
have slower throttle response and may produce
slightly less top-end performance.
Testing Exhaust Temperature
Sensor
1. Disconnect the sensor harness; then remove the
sensor from the exhaust pipe.
2. Suspend the sensor (only up to the threads) in a
container filled with automatic transmission oil;
then slowly heat the oil on a hot plate.
3. Using a fluid thermometer, closely monitor the oil
temperature, and using a digital multimeter with
the leads connected to the sensor leads, observe
the resistance reading.
4. The resistance must be within the temperature
range (see chart).
5. If the resistance and temperature are not within
specifications, replace the sensor.

NOTE: Before replacing the sensor, repeat the
test to confirm results.
ACT Hot Start System
The Sno Pro 600 utilizes a hot start function to aid
start-line performance.
Hot Start Function
The ACT Hot Start feature utilizes the exhaust pipe
temperature sensor to measure the heat in the exhaust
system during the warm-up phase. When the hot start
button is depressed and the warm-up phase is acti-
vated, the internal exhaust pipe temperature will rise
until reaching a pre-set level. Once that temperature
level is reached, the exhaust pipe sensor then signals
the CDI to revert to a spark removing rev-limiting
function. This function will not allow internal exhaust
pipe temperatures to climb beyond the pre-set temper-
ature limit and engine RPM will be held below
engagement. If the internal exhaust pipe temperature
drops below the pre-set temperature limit, the system
automatically reverts to the warm-up phase. This way,
a consistent internal exhaust pipe temperature can be
maintained during the warm-up phase.
Using the Hot Start Function
To use the hot start function, start the engine and depress
the red hot start button located on the left side of the han-
dlebar. This will activate the warm-up function. For best
results, alternate throttle openings between 3/4 and wide-
open during this warm-up phase. When the temperature
in the exhaust pipe reaches the system limit, the system
will switch to the rev-limiting function and a tone change
in the engine’s run quality will occur. This tone change
may also include more frequent engine backfiring. This
backfiring condition will indicate the change from the
warm-up phase to the rev-limiting portion of the system.
Excessive backfiring should be avoided as much as pos-
sible as intake reed petal opening durability may suffer.
To reduce backfiring, a reduction in throttle opening
should help. As internal exhaust pipe temperatures begin
to drop during the rev-limiting function and drop below
the pre-set temperature limit, the system will automati-
cally revert to the warm-up phase. At this time, the initial
3/4 to wide-open throttle warm-up procedure can be
repeated.
Recommended Hot Start Procedure

NOTE: It is not necessary to make excessive use
of the hot start function. Average time to reach
correct exhaust system warm-up is 10-20 seconds.
Racers should test their setup to determine a hot start
procedure that gives the best results. Testing has
shown good results when using the following warm-up
procedure.
When in staging, warm up the engine cooling system
approximately 2-3 minutes.

NOTE: At this time, do not use the hot start function.

NOTE: It is not necessary, and sometimes detri-
mental, to spend excessive time warming up the
engine in staging. Overheating of the engine cool-
ant is possible, and performance can suffer.
Bring the snowmobile to the starting line and activate
the hot start button to begin the exhaust warm-up pro-
cedure. After approximately 10-20 seconds, the tone
or sound of the engine’s exhaust will change as indi-
cated earlier telling the racer that the system is warmed
up. After exhaust system warm-up, the best results
occur if the hot start button is released 10 seconds
before the flag drop, and starting line acceleration is
done in a conventional way using a lightly applied
brake at clutch engagement.
Handlebar Tilt
The handlebar can be adjusted to the operator’s prefer-
ence. To adjust the handlebar, use the following proce-
dure:
1. Loosen the eight cap screws securing the handlebar
caps to the riser and the riser to the steering post.
