Engine break-in
There is never a more important period in the
life of your vehicle 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 oper-
ation or any condition which might result in ex-
cessive engine heating must be avoided.
However, momentary (2–3 seconds maxi-
mum) full throttle operation under load does
not harm the engine.
WARNING
POTENTIAL HAZARD
Improperly operating in reverse.
WHAT CAN HAPPEN
You could hit an obstacle or person be-
hind you, resulting in serious injury.
HOW TO AVOID THE HAZARD
When you shift into reverse, make sure
there are no obstacles or people behind
you. When it is safe to proceed, go slow-
ly.
