APPLICATIONS

Plate compactor is the machine that compacts the ground and 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, finishing the asphalt paving. Applications as followings:

Trench compaction	Earth works
Road maintenance	Land scaping
Brick paving	Driveway toppings

Warning for incorrect application and abuse
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 not effective for jobs that require heavy compaction. In case of compacting ground deeply into lower layer, it is recommended to use Tamping Rammer 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 the other applications.

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 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.
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.
Start the motor using the recoil starter. (If the motor is fitted with an on/off switch this must first be turned to ON before starting.)
For more information of starting and correct operating procedures of the motor, refer to the motor operation manual supplied with the unit.
Increase the motor speed to the maximum setting using the throttle lever, before commencing compacting.
The machine should be controlled by grasping the handle with both hands and applying restraint to control the forward notion. Steer the machine by moving the handle sideways to the right or left.
ALWAYS maintain good footing so that you do not slip and lose control when starting or operating the machine.
