1.4 Electric Motors
All portable electric appliances are dangerous if abused. This machine will only operate on
one voltage. Check the power supply to ensure it corresponds to the voltage as stamped on
the motor. Make sure that the motor is switched OFF before you plug it into the power supply.
When using a portable transformer it must have a minimum output of 3.3kw and be
continuously rated. The symbols on the ON/OFF switch are 0=OFF and I=ON in accordance
with international standards.
1.5 Plugs
The eJXPC50 Plate Compactor is intended for DIY or site usage, the following plug types are
supplied/fitted to the product: 15 amp rated 120 volt plug type.
GREEN / YELLOW = GROUND, BLUE = NEUTRAL, BROWN = LIVE
The wire which is colored Green and Yellow must be connected to the terminal in the plug
marked E or colored Green and Yellow. The wire which is colored Brown must be connected
to the terminal in the plug marked L or colored Red. The wire which is colored Blue must be
connected to the terminal in the plug marked N or colored Black. Always ensure before
connecting to the supply that the supply voltage is the same as the rated voltage marked on
the motor
1.6 Extension Cables
If you need to use an extension cable it must be no longer than 25 metres (82 feet) in length.
The wire section must be 2.5mm2 on 240v and 2.5mm2 on 120v. Ensure that the extension
cable is carefully laid out avoiding liquids, sharp edges and places where vehicles might run
over it. Avoid allowing the extension cable to be trapped underneath the plate compactor.
Unroll it fully or it will overheat and could catch fire. Make sure that any extension cable
connections are dry and safe.
1.7 NVR - No Volt Release
The motors which are fitted to the machine are fitted with a NVR (No Volt Release) Switch.
This mean that if the power fails, the motor will not automatically restart when the power is
restored. The machine will need to be manually restarted.
DO NOT use an extension cable between the transformer and the power
supply. Always ensure that the cable between the 120v machine and
transformer is a minimum length of 10. Ensure cable is fitted with cable clip
to the operating handle at all times.
WARNING
THIS PRODUCT MUST BE GROUNDED
IMPORTANT: The wires in the mains lead are colored in accordance with the
following code:
WARNING

1.8 Health and Safety
1.8.1 Vibration
Some vibration from the compacting operation is transmitted through the handle to the
operator's hands. Refer to specifications & technical data for vibration levels and usage
times (recommended maximum daily exposure time). DO NOT exceed the maximum usage
times.
1.8.2 PPE (Personal Protective Equipment)
Suitable PPE must be worn when using this equipment i.e. Safety Goggles, Gloves, Ear
Protection, Dust Mask, and Steel Toe capped footwear (with anti-slip soles for added
protection). Wear clothing suitable for the work you are doing. Always protect skin from
contact with concrete.
1.8.3 Dust
The compaction process can produce dust, which may be hazardous to your health. Always
wear a mask that is suited to the type of dust being produced.

3. COMPACTION
3.1 Reasons for Compaction
Soil, which has been disturbed or new infill, subbase and blacktop, will have small voids or
air pockets which, if not compacted, will lead to one or more problems occurring.
3.1.1 As traffic crosses the surface of an uncompacted area, the material is compressed. This
leads to subsidence of the top surface as the material fills the voids.
3.1.2 A similar situation occurs with static loads on uncompacted ground. The load (e.g. a
building) will sink.
3.1.3 Materials with voids are more susceptible to water seepage, leading to erosion. Water
ingress may also cause the soil to expand during freezing temperatures and contract during
dry spells. Expansion and contraction is a major cause of damage to building foundations
and normally leads to the structure requiring underpinning.
Compaction increases the density of the material and therefore increases its load bearing
capacity. Reduces air voids and therefore reduces the risk of subsidence, expansion and
contraction, due to ingress of water.
3.2 Compaction Specification
Various methods have been employed in the past to specify the compaction required for
various applications. The factors to consider are, material properties, layer thickness,
pressure applied, vibration and number of passess. Greater understanding of how
compaction works has lead to new compaction specifications being introduced.
3.3 Applications
Applications/materials fall into three categories:
3.3.1 Cohesive materials (less than 20% granular) e.g clay, silt & heavy soils.
3.3.2 Granular materials (more than 20% granular) e.g hard core, sand & light soils.
3.3.3 Bituminous materials e.g asphalt (tarmac), cold lay (bitumin emulsion products).
4. OPERATION
4.1 Pre Start Checks
The following pre start-up inspection must be performed before the start of each work
session or aer every four hours of use, whichever is first. Please refer to the service section
for detailed guidance. If any fault is discovered, the eJXPC50 plate compactor must not be
used until the fault is rectified.
