ATV break-in
A new ATV needs the first 25 hours of
operation to break in the moving parts and
the engine. You can complete your ATV
break-in period by the time you have
used four tanks of fuel.
Within the break-in period, be cautious
when riding your ATV. Do not overload it.
Do not speed up quickly. Always keep your
speed below 25mph (40 km/h).
After the break-in period, your ATV will
perform better.
CAUTION:
For the first three hours, if you run your
engine at full throttle, the engine may
overheat, which could ruin the oil seals and
some operational components. Never run
your engine at full throttle for the first three
hours.
Only use the types of oil recommended in
this manual. Other types of oil may harm
the engine.
