3.10 Engine Speed and Machine Performance
Even a small rise or fall in engine speed will affect the centrifugal force
produced by the exciter. If the engine runs overspeed even slightly, the
centrifugal force will increase significantly and overload the exciter
bearings. If the engine runs underspeed, the centrifugal force will drop
significantly, causing poor compaction and slow travel speeds.
When checking engine speed, use a tachometer for accuracy. Operate
the unit at the appropriate rpm. Refer to the
Technical Data
. Service
engine at recommended intervals and adjust drive belts regularly to
maintain maximum machine performance.
3.11 Operating on Slopes
See graphic: wc_gr000228
When compacting on a slope, only approach the slope from the top.
The operator must never stand between the machine and direction of
descent.
Do not operate on a slope of more than 20°. If this degree of slope is
exceeded, a failure of the engine’s splash-type lubrication system may
result.
