136 OPERATION
MOVING THE VEHICLE — GENERAL INFORMATION
Braking
Avoid sudden stops. Constant sudden stops may negatively affect braking performance and
driving parts. When slowing, leave the clutch (if equipped) engaged as long as possible to
use the braking effect of the engine.
CAUTION
When using the braking effect of the
engine, final gear selection is critical. If
gear selection is too high, the vehicle will
buck which could cause loss of control.
Shifting
Operate in a gear low enough to allow the engine to accelerate to (or maintain) governed
engine speed when applying full throttle. Allowing the engine to lug causes excessive strain
on the engine, which could damage pistons, rings, cylinder walls, or bearings. However, be
sure not to overspeed the engine.
DANGER
Always select the proper gear ratio
BEFORE descending a grade (to avoid a
runaway vehicle and to stay within safe
and legal speed limits). Do NOT coast
down hills. Gear ratios should be selected
to allow the engine to operate between
peak torque and rated speed.
CAUTION
Do not permit a load to drive the engine
above governed speed. When descending
steep grades, use lower gears and watch
the tachometer. Overspeeding will cause
severe drivetrain damage and eventually
destroy the engine.
CAUTION
Running the engine at a speed that is too
low for the load (or grade of the road) can
cause damage to the drivetrain.
