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 sped 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 for ward notion. Forward or backward motion has problem, adjust the red handle or nut s (item21, 22 in 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 when starting or operating the machine.

PRIOR TO OPERATION

Make sure that all dirt, nut, 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 engine, carburetor, and air cleaner.

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.

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.

Check the engine oil level and if the engine oil lever is low, it should be refilled. Use the proper motor oil as suggested in the table below. (Fig- 1)
Prior to Operation

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 2 0 0 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

A 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 employed unavoidable operated in such a place, discharge the exhaust out the roomy a suitable means.

Be careful with the hot members. Mufflers and other hot members are dangerous. Do not touch them with unprepared hand.

Observe with the following cautions when transporting. Clamp fuel tank cap securely, and turn the fuel have OFF at the source during Drain gasoline from fuel tank before transporting over a long distance or on rough roads.

Stop engine without fail before replenishing fuel tank. Never replenish gasoline while the engine is running or remains hot otherwise spilled or evaporated fuel is liable to catch fire from engine sparks or muffler heat. Wipe off spilled fuel, if any, before starting engine. Be careful not to spill fuel.

Keep inflammable way from the vicinity of the exhaust port. Be careful with gasoline match, straw and other inflammable, since the exhaust port is subjected to a hightem perature.
