4.6 Operation
See Graphic: wpmgr006016
Run engine at full throttle and allow plate to pull itself along at its
normal speed. When operating on an incline it may be necessary to
assist plate by pushing it forward slightly. Depending on the material
being compacted, three or four passes are recommended to achieve
the best compaction.
While a certain amount of moisture in the soil is necessary, excessive
moisture may cause soil particles to stick together and prevent good
compaction. If soil is extremely wet, allow it to dry somewhat before
compacting.
If soil is so dry as to create dust clouds while operating plate, some
moisture should be added to the ground material to improve
compaction. This will also reduce service to the air filter.
For compacting asphalt, open water tank valve
(a1) to wet asphalt and
underside of plate. This will prevent asphalt material from sticking. Two
or three passes are usually sufficent to ensure good compaction.
When using plate on paving stones, attach a pad to the bottom of the
plate to prevent chipping or grinding surface of the stones. A special
urethane pad designed for this purpose is available as an optional
accessory.
NOTICE:
DO NOT operate plate on concrete or on extremely hard,
dry, compacted surfaces. The plate will jump rather than vibrate and
could damage both plate and engine.
