OPERATION
2.8 Operation
Run engine at full throttle and allow plate to pull itself along at its normal speed.
Depending on the material being compacted, three or four passes are recommended to
achieve the best compaction.
The machine is best suited to 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 rammer. Where possible the site should be graded and leveled before
commencing compaction.
Correct moisture content in soil 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-filled voids that weaken the soil
’
s load-bearing ability.
Compaction of dry materials will be facilitated by moistening with a water hose fitted
with a sprinkler. 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 film prevents a build up of material on the underside of the plate.
