go slowly.

2. Apply the parking brake.
3. Shift from neutral to reverse and vice versa by
moving the drive select lever along the shift

When in reverse, the reverse indicator light should
come on. If the indicator light does not come on,
have a Yamaha dealer check the electrical circuit.
4. Check behind for people or obstacles, and
then release the parking brake.
5. Open the throttle lever gradually and continue
to watch to the rear while backing.
TIP

If the drive select lever is shifted into reverse while
the engine is running, the engine will stop unless
the rear brake lever or parking brake is applied.

TIP


For ATVs equipped with an odometer or an hourmeter, follow the figures given in km (mi) or the
figures given in hours.

For ATVs not equipped with an odometer or
hour meter, follow the figures given in hours.
There is never a more important period in the life of
your engine than the first 320 km (200 mi) or 20
hours of riding. For this reason, you should read
the following material carefully.
Since the engine is brand new, do not put an ex-
cessive load on it for the first 320 km (200 mi) or 20
hours. The various parts in the engine wear and
polish themselves to the correct operating clear-
ances. During this period, prolonged full-throttle
operation or any condition that might result in en-
gine overheating must be avoided.
0–160 km (0–100 mi) or 0–10 hours
Avoid prolonged operation above 1/2 throttle. Vary
the speed of the ATV regularly. Do not operate it at
one set throttle position.
160–320 km (100–200 mi) or 10–20 hours
Avoid prolonged operation above 3/4 throttle. Rev
the engine freely, but do not use full throttle at any
time.
