OPERATION
6. Before getting underway, allow the
engine to warm-up sufficiently to
ensure good performance.
Above 41°F (5°C), warm-up the
engine for at least 3 minutes.
Below 41°F (5°C), warm-up the
engine for at least 5 minutes at
2,000 rpm.
• If the engine is not properly
warmed up before raising the
engine speed, the buzzer and
overheat indicator may activate
and the engine speed will be
automatically reduced.
• The cooling system may freeze in
areas where the temperature
reaches 32°F (0°C) or below.
Cruising at high speed without
warming the engine up may cause
engine damage.
During the warm-up period, check
the oil pressure indicator (p. 36),
overheat indicator (p. 37), and
cooling system indicator (p. 37).
If the indicators show any
abnormal condition, immediately
stop the engine and determine the
cause of the problem. Refer to
TAKING CARE OF
UNEXPECTED PROBLEMS
on
p. 107 – 111.
