EL
With the engine idling, pull the clutch lever to
disengage the clutch and shift into 1st gear,
and then release the parking brake. Open the
throttle gradually, and at the same time, re-
lease the clutch lever slowly. Once the ATV has
attained adequate speed, release the throttle
lever and at same time, quickly pull in the
clutch lever and shift into 2nd gear. Open the
throttle part way and gradually release the
clutch. Use this same procedure as you move
into the higher gears. Be sure to coordinate the
use of the throttle and shift pedal properly. If
the throttle is applied too abruptly or if the
throttle is not released during shifting, or if the
shift pedal is not released before applying the
throttle, the front wheels may lift off the
ground resulting in a loss of directional con-
trol. Avoid higher speeds until you are thor-
oughly familiar with the operation of your ATV.
WARNING
Always open the throttle gradually and re-
lease the clutch lever slowly. Otherwise, the
machine could wheelie which would increasethe chance of an accident.

covering of control cables becomes damaged.
Cables can also become frayed or kinked. Op-
eration of controls could be restricted, whichcould cause an accident or injury.
Lubricate the inner cables and the cable ends.
If the cables do not operate smoothly, ask a

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