OPERATION
RESTARTING THE ENGINE
If the engine has been stopped using the engine stop switch, restart the engine
using the normal starting procedure. If the engine fails to start, do the following:
1. Re-install the tether switch by securing the tether cap to the base on the
console. Ensure the end of the tether is secured to your clothing.
2. Push the engine stop switch down to the OFF position.
3. Turn the key to the OFF position.
4. Pull the recoil rope handle several times to clear the engine.
5. Restart the engine using the normal starting procedure.
BREAK-IN PERIOD
ENGINE BREAK-IN
IMPORTANT
Engines equipped with an electronic oil pump do not require initial fuel premix.
Excessive heat build-up during the first three hours of operation will damage
close-fitted engine parts. Do not operate at full throttle or high speeds for
extended periods during the first three hours of use. Vary the throttle openings
and vehicle speeds to reduce friction on all close-fitting machined parts, allowing
them to break in slowly without damage.
CAUTION
Never mix brands of oil. Serious chemical reactions can cause injection system
blockage, resulting in serious engine damage. Oils may also be incompatible
and the result could be sludge formation, filter blockage, and reduced cold
weather flow rates. All Polaris oils are compatible with each other.
Drive with extra caution during the break-in period. Perform regular checks on
fluid levels, lines, and all other important areas of the snowmobile.
AUTOMATIC ENGINE BREAK-IN TIMERS
NOTICE
The Patriot engine management system utilizes both a fuel injector break-in
period and oil pump enrichment program. The duration of these break-in
programs are independent of each other and are timed-out based on engine
run-time at and above a specified engine RPM.
