OPERATION
GENERAL OPERATION
The machine is best suited to the compacon of bituminous and granular materials e.g. granular soils, gravels and sands or mixtures of both. Cohesive soils
such as silt and clay could be beer compacted by the use of the impact force produced by a vibrang rammer.
Where possible, the site should be graded and leveled before commencing compacon.
Correct moisture content in soil is vital to proper compacon. Water acts as a lubricant to help soil slide parcles together. Too lile moisture means inadequate
compacon; too much moisture leaves water-lled voids that weaken the soil’s load bearing ability.
Use unleaded grade petrol and ensure that the fuel is free from contaminaon.
The vibratory moon provides a self propelling acon. Posion the handle at the opposite end of the machine to the vibrator.
Start the motor using the recoil starter. (If the motor is ed with an on/o switch this must rst be turned to ON before starng.)
Increase the motor speed to the maximum seng, using the hand throle lever, before commencing compacng.
The machine should be controlled by grasping the handle with both hands and applying restraint to control the forward moon. If forward or backward moon
is problemac, adjust the red handle or nuts (item 21, 22 in components list), steer the machine by moving the handle sideways to the right or le.
Always maintain good foong so that you do not slip and loose control when starng or operang the machine.
PRIOR TO OPERATION
• Make sure that all dirt, etc., are thoroughly removed from the unit prior to operaon. Special eort should be given to the buon face to the vibrang plate
and those areas adjacent to the cooling air inlet of engine, carburetor, and air cleaner.
• Check all bolts and screws for ghtness and make sure all bolts and screws are securely ghtened. Loose bolts and screws may cause damage to the unit.
• Check the V-belt for ghtness. The normal slack should be approximately 10-15 mm (1/2’’) when the belts are forcibly depressed in the middle posion
between the two sheaves.
• If there is excess belt play. There could be a decrease in the impact force or errac vibraon, causing machine damage.
• Check the engine oil level and if it is low, it should be relled. Use the proper motor oil as suggested in the table below. (Fig.1)
• Remove the oil plug in the vibrator assembly and check the oil level. Make sure the compactor's level when checking. The oil level should be up to the oil
plug. Every month or every 200 hours of operaon, replace the oil.

IMPORTION
Use the motor oil SAE
• When changing the oil, the old oil can be drained by pping the unit. The oil will drain easily while is hot.
• A regular grade gasoline should be used in the engine.
• When lling the fuel tank, make sure the fuel lter is used.
CAUTION
• Be careful with the operang place and venlaon. Avoid operang the machine in a closed room, tunnel, or other badly venlated places, since its exhaust
contains deadly poisonous carbon monoxide. If the machine is employed unavoidable operated in such a place, discharge the exhaust out of the room by
suitable means.
• Be careful with hot members. Muers and other hot members are dangerous. Do not touch them with unprepared hand.
• Observe the following cauons when transporng. Tighten the fuel tank cap securely and turn o the fuel supply during the draining of petrol from the fuel
tank before transporng over long distances or uneven 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 re from engine sparks or muer heat. Wipe o spilled fuel, if any, before starng engine. Be careful not to spill fuel.
• Keep inammable way from the vicinity of the exhaust port. Be careful with the use of inammables, since the exhaust port is subjected to a high temperature.
