CAUTION:_ Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “ENERGY CONSERVING II”)
contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting
in reduced component life and poor engine
performance.

With the engine idling, shift the drive select lever to
the low position “L” or the high position “H”. Apply
the throttle slowly and smoothly. The centrifugal
clutch will engage and you will start to accelerate.
If the throttle is applied too abruptly, the front
wheels may lift off the ground resulting in a loss of
directional control. Avoid higher speeds until you
are thoroughly familiar with the operation of your
ATV.
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. Im-
proper use of the brakes can cause the tires to
lose traction, reducing control and increasing the
possibility of an accident.CAUTION:_ Do not shift from drive position low “L” to high
“H” or vice versa without coming to a com-
plete stop. Damage to the engine or drive train
may occur. _

9. Fill the engine with sufficient oil to reach the
specified level. Install the dipstick and tighten

tives could cause clutch slippage.


Be sure no foreign material enters the
crankcase.
