Break-In Period

Engine Break-In

The recommended break-in period is the time required to use the first full tank of fuel.

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.

The engine management system utilizes both a fuel injector break-in period and oil pump enrichment program. The duration of these break-in programs is independent of each other and is timed out based on engine run time. Regardless of these automatic engine break-in and enrichment features, the following engine break-in procedures must be performed when the engine is new or overhauled.

NOTE

During this period of increased oiling, sled performance will not be affected and you should ride normally.

Break-In Function	Engine Run Time	Description
Fuel Injectors	2 Hours	Additional fuel
600 Models Oil Pump Enrichment Period	5 Hours *	Enriched oil supply to engine
800 Models Oil Pump Enrichment Period	18 Hours *	Enriched oil supply to engine
* = Total engine run time above 5,500 RPM

Oil Recommendations
First Tank of Fuel:	POLARIS VES 2-Cycle Oil
After Break-in:	POLARIS VES 2-Cycle Oil
Extreme Arctic Conditions, sustained temperature is at or below -40° F (-40° C)	VES Extreme 2-Cycle Oil

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.

NOTICE

Use of any lubricants other than those recommended by POLARIS may cause serious engine damage. We recommend the use of POLARIS lubricants for your vehicle.

Drive with extra caution during the break-in period. Perform regular checks on fluid levels, lines, and all other important areas of the snowmobile.

Oil Injection System

Always check and fill the oil bottle when refueling.

NOTICE

Serious engine damage can occur without the proper lubrication. Check the oil bottle level often during the first tank of fuel. If the oil level doesn't go down, contact your dealer or equivalent person immediately.

Drive Belt Break-In

The break-in period for a new drive belt is 30 miles (48 km). During this time, vary the throttle position under 50% and limit full throttle use.
New drive belts should be washed with warm, soapy water and allowed to air dry prior to use.
Always take time to warm up the belt and driveline prior to operating the snowmobile. Free the track and skis from the ground before engaging throttle.
