Engine break-in
There is never a more important period in the life of
your machine than the period between zero and 20 hours.
For this reason, we ask that you carefully read the following
material. Because the engine is brand new, you must not
put an excessive load on it for the first several hours of
running.
During the first 20 hours, the various parts in the engine
wear and polish themselves to the correct operating
clearances.
During this period, prolonged full throttle operation or
any condition which might result in excessive engine
heating must be avoided.
However, momentary (2-3 seconds maximum)full throttle
operation under load does not harm the engine.
0-10 hours:
Avoid continuous operation above half throttle. Allow
a cooling off period of five to ten minutes after every
hour of operation. Vary the speed of the machine from
time to time. Do not operate it at one set throttle position.
Each ful l th rottl e acceler ation sequen ce sh ould be
followed with a substantial rest period for theengine by
cruising at lower r/min so the engine can riditself of the
temporary build up of heat If any abnormality is noticed
during this period, consult a ATV dealer.
