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 diesel
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.
