APPLICATIONS

A plate compactor is a machine that compacts the ground, and it intends to make the surface smooth, by transmitting vibration through a vibrating plate, which power powered by a single motor in a 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 follows:

• Trenchcompaction
• Roadmaintenance
• Brickpaving
• Earthworks
• Landscaping
• Drivewaytoppings

Warning for incorrect application and abuse

This machine is hard to move forward on soil with much water (especially clay soil).It is not suitable for such an application. This machine is difficulty leveling the ground, including big stones, due to insufficient compacting force. Plate compactor is mainly applied for compacting the surface, and it is not effective for jobs that require heavy compaction. In case of compacting ground deeply into the lower layer, it is recommended to use. Tamping Rammer, Vibrato Compactor, and Vibration Roller, whose compacting force is rather effective. Please use this compactor for compacting the surface on soil, sediment, sand, beaching, and asphalt. It is not recommended to use this machine for other applications.

STRUCTURE

• The upper part is made up of Power Source, Handle, Belt Cover, and Guard Hook, which are fixed by the Engine base.
• The Engine base is fixed on a Vibrating Plate by Shock shock-absorbing rubber. The lower part is made up of Vibrating Plate and a Vibrator unit that has an Eccentric rotary shaft built in.
• The power source is transmitted from the centrifugal clutch on the engine output shaft to the eccentric rotary shaft via a V-belt.

Power Transfer

• An air-cooled single-cylinder engine is mounted as a power source, and a Centrifugal Clutch is fixed on the engine output shaft. Petrol Engine(2-cycle, 4-cycle) and Diesel Gasoline Engine can be mounted as an option. The Centrifugal Clutch engages by running up the engine, and the engine is reduced a suitable number for compacting. The rotation of the engine is transmitted from the V-pulley integrated with the Clutch drum to the Vibrator pulley through the V-belt. The Vibrator Pulley rotates the Eccentric rotor shaft that is contained in the Vibrator case. The generated vibration created from the eccentric rotor is transmitted to the Compaction with the weight of the machine, making the compaction of the ground possible.

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 hand throttle lever, before commencing\ compacting.
• 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 a problem; adjust the red handle or nuts (item 21, 22 in components list). Steer the machine by moving the handle sideways to the right or left.
• ALWAYS maintain a good footing so that you do not slip and lose control when starting or operating the machine.

PRIOR TO OPERATION

1. Make sure that all dirt, nuts, etc., are thoroughly removed from the unit prior to operation. Special effort should be given to the button face of the vibrating plate and those areas adjacent to the cooling air inlet of the engine, carburetor, and air cleaner.
2. Check all bolts and screws for tightness and make sure all bolts and screws are securely tightened. Loose bolts and screws may cause damage to the unit.
3. Check the V-belt for tightness. The normal slack should be approximately 10-15 mm (1/2″) when the belts are forcibly depressed in the middle position between the two sheaves. If there is excess belt play. There could be a decrease
   in the impact force or erratic vibration, causing machine damage.
4. Check the engine oil level and if the engine oil level is low, it should be refilled. Use the proper motor oil as suggested in the table below. (Fig-1)
5. Remove the oil plug in the vibrator assembly and check the oil level. Make sure the compactor is level when checking. The oil level should be up to the oil plug. Every month or every 200 hours of operation,\ replace the oil.

IMPORTION

• Use the motor oil SAE. When changing the oil, the old oil can be drained by tipping the unit. The oil will drain easily while it is hot.

Regular grade gasoline should be used in the engine. When filling the fuel tank, make sure the fuel filter is used.

CAUTION

• Be careful with the operating place and ventilation. Avoid operating the machine in a closed room, tunnel, or other badly ventilated places, since its exhaust contains deadly poisonous carbon monoxide.’/
• If the machine is unavoidably operated in such a place, discharge the exhaust out of the room by a suitable means.
• Be careful with the hot members. Mufflers and other hot members are dangerous. Do not touch them with unprepared hands.
• Observe the following cautions when transporting. Clamp the fuel tank cap securely, and turn the fuel off at the source during Drain gasoline from the fuel tank before transporting over a long distance or on rough roads.
• Stopenginewithoutfailbeforereplenishingfueltank. Never replenish gasoline while the engine is running or remains hot; otherwis, spilled or evaporated fuel is liable to catch fire from engine sparks or muffler heat. Wipe off spilled fuel, if any, before starting the engine. Be careful not to spill fuel.
• Keep inflammables away from the vicinity of the exhaust port. Be careful with gasoline matches, straw, and other inflammable materials, since the exhaust port is subjected to a high temperature.

STARTING

Gasoline Engine

•  Turn the STOP SWITCH counterclockwise to the position “I”(ON) (Fig. 3)
• Open the fuel cock. (Fig-4)
• Set the speed control lever 1/3 to 1/2 of the way towards the high speed position. (Fig-5)
• Close the choke lever.
• If the engine is warm or the ambient temperature is high, open the choke lever halfway, or keep it fully open.
• If the engine is cold or the ambient temperature is low, close the choke lever fully. (Fig-6)
• Pull the starter handle slowly until resistance is felt. This is the “compression” point. Return the handle to its original position and pull swiftly.
• Do not pull out the rope all the way.
• After starting the engine, allow the starter handle to return to its original position while still holding the handle.(Fig-7)
• Diesel Engine 3-6. Turn the throttle lever to the START position (open by about 30 degrees) (Fig-5-D) 3-7. Operate Starter. In case of a recoil starter By pulling the starter knob slowly, you will reach such point where the resistance becomes strong (compression point). By pulling it further, you will find a point where resistance is reduced. Return the knob, but slowly return it original. (Fig-7 -D )

CAUTION

• Do not pull the rope all the way and do not take your hand off the pulled knob but slowly return it original position.
