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 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
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.
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
