OPERATION
NOTICE! This tool ships without oil. Consult the engine manual on how to refill
the engine oil. See Lubrication section in this manual on how to fill the vibrator
with oil. Failure to fill engine or vibrator with oil before starting the engine will
result in permanent damage to the tool.
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 the 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.

V4.4 208cc Reversible Plate Compactor 8622953
Visit www.princessauto.com for more information 11
4. Stones/Broken Concrete – Remove large stones or chunks of concrete as the
compactor does not break these apart. Larger stones and broken concrete
may not compact as much as expected. Compaction is more effective with
smaller objects.
5. Obstacles – A work site may have natural obstacles (stump, buried stones) or
manmade obstacles (construction waste, power cords or hoses) that
will interfere with the compacting process. Check the work area and remove all
obstacles before beginning compacting.
OPERATING THE PLATE COMPACTOR
The plate compactor is started with the throttle lever in low gear. The power
bypasses the centrifugal clutch and the base plate does not vibrate.
Once the throttle lever is opened, the base plate begins to vibrate. As the throttle
lever is opened further, the vibrating force increases in strength and frequency. This
results in deeper compaction.
WARNING! Maintain a grip on the tool at all times when under power, as it will
move by itself when the throttle is open and may pose an injury risk to
bystanders and the operator.
1. Check the plate compactor before use (see Maintenance Chart - Daily
before operating)
1.1 Check the gasoline engine before use per the separate engine
instruction manual.
1.2 Attach the paving pad to the bottom of the plate when compacting paving
stones to prevent chipping or grinding the surface.
2. Position the throttle lever in low gear.
3. Position the stick shift in the neutral middle position so the compactor will
not move.
4. Start the gasoline engine per instructions in the engine instruction manual.
5. Hold the compactor handle and move the throttle lever towards high gear. The
vibrator assembly will engage and begin compacting.
6. Push the stick shift forward and the compactor will begin moving forward. Pull
the stick shift into reverse and the compactor will move backwards. The higher
the throttle setting the faster it will move forward or backward.

8622953 208cc Reversible Plate Compactor V4.4
12 For technical questions call 1-800-665-8685
7. Retain a hold of the handle and guide the tool as it compacts. Inclines may
require a gentle pressure to maintain forward momentum (see Compacting on
an Incline).
8. Watch for obstacles in the tool’s work path that can create a dangerous hazard
or may damage the tool. Move the stick shift into neutral and the throttle lever
to low gear and wait for the compactor to stop moving before removing the
obstacle. Turn the tool off and move to a safe location if the object will require
more than a few seconds to remove.
9. The surface may require 3 or 4 passes to achieve full compaction. The type of
surface material will determine how many passes are needed. The tool will
begin to bounce when the material is compact.
10. Move the stick shift to neutral and the throttle lever to low gear once the job is
complete. Wait until the tool stops vibrating. Shut the engine off per the engine
instruction manual instructions and allow it to cool.
10.1 Let the engine idle for several minutes before shutting it off if the
compactor was used for a length of time or the job was hard on the
equipment. This will allow a gradual cooling of the engine components
without damage.
FORWARD AND REVERSE MOTION
The direction of travel is determined with the operating
stick shift. Depending on the position of the stick shift,
the plate compacts in forward direction, on the spot or
in reverse direction.
1. Push the stick shift forward to move the
compactor forward (F).
2. Place the stick shift in the neutral position and the
compactor will vibrate on the spot (N).
3. Pull the stick shift back and the compactor will
move in reverse (R).
COMPACTING HIGH CLAY CONTENT SOIL
A dry intermediary material may be used to cover the soil surface to prevent the soil
from sticking to the compactor’s base plate.
Fig. 5

V4.4 208cc Reversible Plate Compactor 8622953
Visit www.princessauto.com for more information 13
1. To compact soil with a high clay content, reduce speed so the compactor’s
base plate is still vibrating, but not leaving the surface. This will require the
operator to push the compactor more to account for the loss of
natural momentum.
2. Check underneath the base plate and remove all material that is stuck after
each pass or more often if required.
3. Double the number of passes to compact the soil as the plate compactor is not
at full power.
COMPACTING ON AN INCLINE
WARNING! Never stand below the plate compactor when using on an incline as
it may topple and cause a serious injury. When changing direction, always
remain uphill.
WARNING! Stop compacting immediately if the tool is difficult to control on an
incline. The tool may topple and cause a serious injury to the operator or
bystanders.
The incline cannot exceed a 20° angle. There may be a risk that the tool will topple
during compaction. The angle will also prevent the oil lubrication system from
operating correctly and damage the engine.
1. The best method of compacting on an incline is starting at the top and moving
down the incline.
2. Adjust the speed that the compactor moves with the throttle, until it
is comfortable.
3. At the slope’s bottom, move the throttle to idle speed to stop the base plate
from vibrating.
4. Pull the plate compactor to the top of the incline and fully open the throttle to
start the base plate vibrating. Resume the soil compacting.
4.1 The wheel assembly will make it easier to pull the plate compactor up the
incline.
5. A shallow incline may allow compacting from side-to-side, moving down the
incline as each section is complete. In this case, compacting on an incline may
require the operator to lightly push the tool to maintain forward momentum.
