BEF320-2A
Operating Manual
GENERAL OPERATION
It is essential that the cutters are not lowered too far and too hard onto the surface as serious
damage could be caused to the machine and cutter drum assembly.
THE cutters must be allowed to "float" on the cutter shafts without excessive downward pressure.
This floating action allows the cutters to perform as the designer intended i.e. as cutters rather
than as grinders or picks. Do not pull the control levers into reverse when cutting as this could
result in the machine reversing quickly in an uncontrolled manner.
The machine should operate smoothly with a minimum of vibration. When the depth of cut
is correctly set very little effort should be required to operate the machine.
EXCESSIVE downward pressure on the cutters may marginally improve the work rate/finish but
the definite increase in wear rates on the cutter drum assembly and machine components is the
negative result. Remember two light passes are quicker and more cost effective than one slow
heavy pass. Tests have proven conclusively that heavy downward pressure reduces cutter and
drum life by over 50%.
The BEF320 should always be operated in a forward direction. The operator varies the speed of
travel to determine the final finish having already pre-set the depth control. It is recommended that
the machine is not operated in reverse whilst the cutters are in contact with the surface. When
lifting the cutter drum from the work surface it is not necessary to turn the hand wheel - lift
upwards by simply operating the hydraulic lift lever.
The BEF320 machine should always be moved by its own hydraulic power driven system as
pushing the machine continually around by hand could result in internal damage to the hydraulic
motor and pump system.
This manual should be read in conjunction with the owners manual of the petrol engine. The
engine is designed to give safe and dependable service if operated according to the instructions.
Read and understand the owners manual before operating the engine. Failure to do so could
result in personal injury or equipment damage.
DUST CONTROL
To control any dust created by the operation connect an industrial dust collector or vacuum to the
50mm port at the side of the machine. We recommend the SPE 316 for almost 100% dust
control. In the absence of a dust control unit it is acceptable to spray water onto the surface or to
feed water down the vacuum port. Cutter drum assembly life is increased by around 10% when
operating the machine in this way.
