OPERATION
Oil
Low Oil Indicator Light
The low oil indicator light (standard on most models) will indicate
when to add oil. However, always check the oil level when refueling.
When the low oil indicator light is on, oil should be added before
further operation of the snowmobile. Visually check the oil level
in the bottle. The engine may be operated as long as oil is
visible in the oil tank. If oil is not visible, continued operation
may cause serious engine damage.
Never mix brands of two cycle oil. Serious chemical reactions
may occur, causing injection system blockage This may result
in serious engine damage and the voiding of engine warranty.
Always maintain the oil level above the tank’s low level line. This
is especially important when the machine is operated in
mountainous terrain. Maintaining the proper oil level will prevent
system aeration and possible loss of pumping action, which
could result in engine damage.
