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 levelled 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 and 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 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 tted with an on/off switch this must rst be turned to
ON before starting.)
For more information on 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 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.
