RIDING YOUR ATV
WARNING
Checking maintenance items when the engine is running could be hazardous.
You could be severely injured if your hands or clothing get caught in moving
ATV parts.
Shut the engine off when performing maintenance checks, except checking the
engine stop switch and throttle.
BREAK-IN
The first month is the most important in the life of your vehicle. Proper operation
during this break-in period will be helpful for assuring maximum life and performance
of your new vehicle. The following guidelines explain proper break-in procedures.
Maximum Throttle Opening Recommendation
During the first 10 hours of operation, You should always use less than ½ throttle
opening.
Vary the Engine Rotating Speed
Vary the engine rotating speed during the break-in period. This allows the parts to
“load” and then “unload” (allowing the parts to cool). Although it is essential to place
some stress on the engine components during break-in, you must be careful not to
load the engine too much.
Avoid Constant Low Rotating Speed
Operating the engine at constant low rotating speed (light load) can cause parts to
glaze and not seal properly. Allow the engine to accelerate freely without exceeding
the maximum throttle limit.
Allow the Engine Oil to Circulate Before Riding
Allow a few minutes of idling time after warm or cold engine starting. This allows the
lubricating oil to reach all critical engine components.
Observe Your Initial and Most Critical Service
The initial service (break-in maintenance) is the most important service that your
vehicle will receive. Observing a proper break-in operation, will help engine
components seal properly. Maintenance required as part of the initial service includes
proper adjustments, tightening of all bolts & nuts, and replacement of dirty oil. Timely
performance of this service will help you get the best service life and performance of
the engine.
