2BFOREWORD
It is important that the following information be read
carefully in order that the operational characteristics and
performance of the Bartell Surface Preparation System be
fully understood. Proper adherence to operation and
maintenance procedures will ensure long life and top
performance of your equipment.
SAFETY PRECAUTIONS
Always keep unauthorized, inexperienced, untrained
people away from this machine.
Rotating and moving parts will cause injury if
contacted. Make sure guards are in place. Keep
hands and feet away from moving parts.
Fuel the machine only when the engine is stopped,
using all necessary safety precautions.
The engine must always be stopped before
attempting any repair or adjustments. Ignition switch
should be off. Danger: Never operate the machine
in an explosive atmosphere, near combustible
materials or where ventilation does not clear
exhaust fumes. Repair fuel leaks immediately.
Refer to your engine owner’s manual for more
safety instructions.
Be careful not to come in contact with the muffler
when the engine is hot, serious burns may result!
Do not run the air motor without sufficient oil in the
lubrication system. The lubricant levels should be
checked regularly on gas and air powered units. Refer
to manufacturer’s manual for amounts.
Before starting you SPS machine, always raise the
cutter cage assembly using the hand knob
adjustment, so that cutters do not contact the surface.
OPERATING PRINCIPLE
The SPS employs a belt-pulley drive, for the cages which
contact the surfaces to be prepared. The hand knob
adjustment allows the cages to be raised or lowered as
necessary to perform efficient work. The vibration
isolators on the bridge make it easier on the operator and
the machine, while the hexagonal drive bearing produces
more positive cutter engagement. A dust control vacuum
should be used to provide a clean work area.
The SPS Machine is designed to run at an engine speed
(engine take off shaft) of 3600 rpm. (normally considered
full throttle).
Never force the cutter head into the surface to a point
where the machine starts to bounce. This will minimize
results and do more damage to the machine than the
work surface. Let the cutters do the work, but make sure
you have the best cutter/cage assembly for the job.
WORKING WITH THE SPS
We have found that working the machine in a figure “8”
pattern, when milling misaligned concrete slabs or joints
will produce more aggressive removal of material. The
cutters will work against the cut and tend to produce
more consistent and faster removal of material. Moving
the machine in a straight line tends to create grooves
that the cutters will follow. The Tungsten Carbide Tipped
cutters produce the longest life in milling applications
and should be considered as the best choice, in spite of
the higher initial costs. Your time is valuable and when
you have to change cutters or even cutter assemblies
you are not using the machine to make money.
When using the SPS to mill concrete, work the left
side or belt guard side, riding on the high side of the cut,
if possible. This will avoid the possibility of the drive
pulley engaging the work surface. Regularly check that
the drive pulley is aligned properly and secured to the
drive shaft.
When using any Cutter Cage Assemblies, there will be
variations in the floor. The depth of cut should be
adjusted with the hand knob to maintain an equal
penetration of the work surface.
Grooving set ups are possible with the SPS in as
many configurations as you need. The normal set up of
the R123 uses cutters spaced with 1” centers, braced by
tension springs. They could also be set up with other
centers, but bear in mind that they must always be
tensioned to maintain the path you require.
Checkerboard effects are possible by working the
machine at 90° to the path first established.
When using the Edger attachment for crack chasing,
try the following method. Mark the front of the edger with
a chalk guide line to correspond to the starting point of
the crack. Lower the head into the crack and push the
machine forward along the fault line using the chalk
mark as the steering guide. Using carbides gives the
longest life, but B-2 and B-3 cutters may also be used in
the set up. Always tension the cutters in the cage with
spring load to maintain a consistent path.
CUTTER LIFE
How long cutters and cages last on a particular job is a
difficult thing to predict. There are a number of variables
involved which must always be considered. How
old/hard is the material you are working with? Are there
any hardeners on additives that will slow you down? Are
you forcing the cage into the surface? Is the equipment
properly maintained? Is the operator familiar with the
machine and its capabilities? Do you have the proper
cutter/cage set up for the application?
There are additional cutters and cages to those below,
but this is a fair representation of estimated rates for
production and cutter life. We preset them as a guide
only, due to variables such as above.
