2.7 Operation
Run the engine at full throttle and allow plate to pull itself along at its normal speed. When operating 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.
The machine is best suited for the compaction of bituminous and granular materials e.g. granular soils such
as silt and clay are best compacted using the impact force produced by a vibrating plate. Where possible the
site should be graded and leveled before compaction.
Correct moisture content in soil also is vital to proper compaction. Water acts as a lubricant to help slide soil
particles together. Too little moisture means inadequate compaction; too much moisture leaves water-lled
voids that weaken the soil’s load-bearing ability. Compaction of dry materials will be facilitated by moisten-
ing with a water hose tted with a sprinkler or simply by using the water tank provided. Excessive watering or
water content will cause the machine to stall.
The optional water tank kit is recommended when the machine is used on bituminous surfaces as the water
lm prevents a build up of material on the underside of the plate.
