OPERATION

IMPORTANT! Before digging or compacting, contact
your local utilities to determine the location of buried
pipes or cables.
The plate compactor can compact loose soil, sand, gravel,
asphalt and broken concrete. Soils with a high clay content are
not recommended for compacting with this tool, but it can be
done with the proper technique (see Compacting High Clay
Content Soil).
The tool vibrates the surface through the base plate,
forcing the soil/gravel into a smaller physical space. The
surface material must be loose enough to allow movement
during compaction. Some surfaces may require preparation
before compacting.
A surface that is too hard can cause the tool to bounce instead
of compact. This may damage the tool or cause a vibration
injury over time due to repeated exposure. A bouncing plate
compactor indicates the material is compact. Add another
layer of material if building up a compacted area.

PREPARING THE SURFACE

1. Dry Surface – A dry surface will produce dust during
compaction. Sprinkle water over soil and allow it to soak in,
before resuming compaction. Only sprinkle enough water
on gravel to keep the dust down. This will extend the life of
the engine's air filter.
2. Wet Surface – Soil that is too wet may stick to the base plate.
The sticking soil will then compact onto the tool and cause
excess weight that can put more stress on the engine. It will
also prevent the proper compaction of the soil surface. Dry
the surface or wait until it is suitable for compaction.
3. Asphalt - Wet the asphalt surface and base plate of the tool
to prevent the asphalt from sticking during compaction.
Dampen the surface and base plate as needed.
