EBU00207
To decelerate:
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. As you slow down, shift to a lower
gear. Be sure that the engine has sufficiently
slowed before engaging a lower gear. Improp-
er use of the brakes or shifting can cause the
tires to lose traction, reducing control and in-
creasing the possibility of an accident.
EBU00209
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 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. Each full throttle acceler-
ation sequence should be followed with a sub-
stantial rest period for the engine by cruising
at lower r/min so the engine can rid itself of the
temporary build up of heat.
WARNING
POTENTIAL HAZARD
Engaging a lower gear when the engine
speed is too high.
WHAT CAN HAPPEN
The wheels could stop rotating. This
could cause loss of control, an accident
and injury. It could also cause engine or
drive train damage.
HOW TO AVOID THE HAZARD
Make sure the engine has sufficiently
slowed before shifting to a lower gear.
