General Safety Instructions for the Operation of
Power Equipment
Our factory's goal is to produce power equipment that helps the
operator work safely and efficiently. The most important safety
device for this or any tool is the operator．Care and good
judgement are the best protection against injury．All possible
hazards cannot be covered here, but we have tried to highlight
some of the important items individuals should look for and obey
Caution, Warning and Danger signs placed on equipment, and
displayed in the workplace. Operators should read and follow
safety instructions packed witheach product.
Learn how each machine works. Even if you have previously
usedsimilarmachines．carefullycheck outeach machinebefore
youuse it,Get the"feel"of itand knowits capabilities, limitations,
potential hazards, how it operates, and how it stops.We has no

APPLICAIONS
Plate compactor is the machine that compactsthe groundand
it intends to make the surface smooth，by transmitting vibration
through vibrating plate，which power generated from single
motor in vibrator case This machine is suitable for making the
ground surface smooth, such as leveling the soil and beaching,
finishingtheasphalt paving.Applications asfollowings：
Trenchcompaction Earthworks
Road maintenance Landscaping
Brickpaving Drivewaytoppings
!Warningforincorrectapplicationandabuse
This machine is hard to move forward on a soil with much water
(especially clay soil). It is not suitable for such application. This
machine is difficult to level a ground include big stones due to
insufficient compacting force. Plate compactor is mainly applied
for compacting surface smooth and it is nor effective for jobs that
requires heavy compaction. In case of compacting ground
deeply into lower layer, it is recommended to use Tamping
Rammer ，Vibrator Compactor and Vibration Roller which
compacting force is rather effective. Please use this compactor
for compacting surface on soil, sediment, sand, beaching and
asphalt. It is not recommended for use this machine for any
other applications.
STRUCTURE
The upper part is made up of Power source, Handle, Belt Cover
and Guard hook which are fixedby
Engine base. The Engine base is fixed on Vibrating Plate by
ShockabsorbingRubber．Thelowerpertis madeup ofVibrating
plate and Vibrator until that has an Eccentric rotary shaft built in.
The power source is transmitted from the centrifugal clutch on
engine output shaft to the Eccentric rotaryshaft via V-belt.

FUNCTIONS AND CONTROLS
Motor
The motor is controlled by an ON/OFF switch or push button
which is mountedon the motorbelowthe fuel tank．
The motor speed is controlled by a remote throttle lever which is
mountedonthemachine handle．
Honda and Kama motors are fitted with an oil alert device which
will stop the motor or prevent starting when the crankcase oil
level falls below a safe level.
Drive belt
Tension of the drive belt is adjustable．Loosen the four nuts on
the bolts which secure the motor to the base plate,Adjust the set
screws which bear against the motor crankcase to achieve the
requiredbelttension．Ensurethat thefour nuts andthe setscrew
locknutsaretightenedafteradjustment．
ACCESSORIES
Transport Trolley-facilitates handling．Hooks into the base-
plate．Fitted with 200mm rubber tyres.

HAZARDS AND RISKS
NEVER allow any person to operate the machine without
adequate instruction．
ENSURE all operators read ，understand and follow the
operating instructions．
SERIOUS INJURYcould result from improper orcareless use of
thismachine
Plate compactors are heavy units and should be positioned by
two people of appropriate strength．Using the lifting handles
provided on the machine, along withcorrect lifting techniques．
! MECHANICALHAZARDS
DO NOToperatethemachine unlessallprotectiveguardsare
in place．
KEEPhands and feet clear of rotating and moving parts as they
willcauseinjuryif contacted．
ENSURE that the motor operation switch is in the OFF position
and the spark plug ignition lead isdisconnected before removing
the guardsormakingadjustments．
ENSURE both the machine and the operator are stable by
setting up on level terrain and the machine will not tip over, slide
or fall while in operation or unattended．
DO NOTleavethemachine inoperation whileit isunattended
ENSURE that the walls of a trench are stable and will not col-
lapse due to the action ofthe vibration,priortocommencing
compaction．
ENSURE that the area to be compacted does not contain any
"live" electrical cables,gas,water or communication services
which may be damaged bythe action ofthe vibration．
EXERCISECAREwhen operatingunit．Exposuretovibrationor
repetitive work actions may be harmful to handsand arms．
NEVER stand on the unit while it is operating.
DO NOT increase the governed no-load motor speed above
3,500 r/min. Any increase may result in personal injury and
damageto themachine．
BE CAREFUL not to come in contact with the muffler when the
engineis hot,sinceit cancausesevereburns．
ENSURE that repairs to the motor and machine are carried out
personnel．
! FIRE & EXPLOSION HAZARDS
PETROL is extremely flammable and explosive under certain
conditions．
ENSURE that petrol is only stored in an approved storage
container．
DO NOTrefuel the motor whileit is in operation or hot.
DO NOTrefuel the motor in the vicinityof sparks, a naked flame
or a person smoking．
DO NOT over fill the fuel tank and avoid spilling petrol when
refueling．Spilled petrol or petrol vapour may ignite．If spillage
occurs,ensure that the area is drybeforestartingthe motor．
ENSURE thatthe fuel tank capis securely fitted after refueling．
! CHEMICALHAZARDS
DO NOT operate or refuel a petrol or diesel motor in a confined
area withoutadequate ventilation．
CARBON MONOXIDE exhaust gases from internal combustion

OPERATION
GENERAL OPERATION
The machine is best suited to the compaction of bituminous and
granular materials e.g. granular soils, gravels and sands or
mixtures of both．Cohesive 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
commencingcompaction．
Correct moisture content in soil is vital to proper compaction.
Water acts as a lubricant to help slide soilparticles together. Too
littlemoisturemeansinadequatecompaction；too muchmoisture
leaves water-filled voids that weaken the soil's load bearing
ability．
Use unleaded grade petrol and ensure that the fuel is free from
contamination．
The vibratory motion provides a self propelling action.Position
the handle at the opposite end of the machine to the vibrator．

5
Start the motor using the recoil starter．(If the motor is fitted with
an on/offswitch this mustfirst be turned to ONbefore starting.)
For more information on starting and correct operating
procedures of the motor,refer to the motor operation manual
sup-plied with the unit．
Increase the motor speed to the maximum setting using the
handthrottle lever,before commencingcompacting．
The machine should be controlled by grasping the handle with
both hands and applying restraint to control the forward
motion.Forward or backward motion has problem,adjust the red
handle or nuts(item 21,22in components list)
Steer the machine by moving the handle sideways to the right or
left．
ALWAYS maintain good footing so that you do not slip and loose
control whenstartingor operating the machine
