OPERATING INSTRUCTIONS
INTENDED USE: This unitisdesigned toplane / mill horizontal surfaces consisting of rock,
concrete and asphalt. Use in any other way is considered contrary to the intended use.
GENERAL INFORMATION
The DIGGA Profiler attaches to the toolbar/quick-attach mechanism ofyour skid steer loader. Due to
this arrangement, thorough knowledge of the skid steercontrols isnecessary for machine operation.
Read and understand your skid steer operator's manual for information regarding skid steer
operation before attempting to use the profiler.Check the surface to be planed. The standard all
purpose picks can be used to mill bothasphalt and concrete. There are optional concrete picks that
are recommended ifthe profiler isto be used extensively for concrete. These picks do not perform as
well when milling asphalt, especially in warmer weather. Review the job at hand and determine the
required depth and tilt ofthe cut, and also the side shift position of the profiler.Best performance is
obtained when the road profiler isin the center position. Side shift should be used when visibility is a
determining factor, such as milling around manholes or when milling next to an obstacle such as a
building.
NOTE: Although the wheel assemblies are standard, they may be removed when distance is a factor
such as milling nexttoan obstacle or building.
WARNING! EXPOSURE TO RESPIRABLE CRYSTALLINE SILICADUST ALONG WITH OTHER
HAZARDOUS DUSTS MAY CAUSE SERIOUS OR FATAL RESPIRATORY
DISEASE. IT IS RECOMMENDED TO USE DUST SUPPRESSION, DUST
COLLECTION AND IF NECESSARY PERSONAL PROTECTIVE EQUIPMENT
DURING THE OPERATION OF THE PROFILER OR OF ANY ATTACHMENT
THAT MAY CAUSE HIGH LEVELS OF DUST.
OPERATING INSTRUCTIONS
1. Clear area ofallbystanders.
2. Lift the profiler until the drum is off the ground and start drum rotation. (Teeth at the bottom of
the drum must be moving in the same forward direction that the profiler travels).
DIRECTION OF
TRAVEL
NOTE: Mill only when the skid steer is traveling forward. Do not operate when traveling in reverse.

OPERATING INSTRUCTIONS
NOTE: Hydraulic cylinders tilt the profiler,adjust the depth ofboththe left and right side of the
planer individually, and also shift the profiler tothe left orright.
3. Increase engine RPM and with the drum turning you can make any necessary
adjustments to the side shift. Do not side shift the road profiler during milling operation.
Once the desired side shift position has been achieved you are ready to begin. The
drum will not cut in a side to side motion. Tilt and Depth control can both be activated
during milling.
IMPORTANT: The drum MUST be turning to make any hydraulic adjustment to the profiler.
4. Position the profiler at the desired starting point. Set the left and right depth gauge tothe
desired depth mark on the profiler.Maximum depth of each cut isdetermined by the type of
material, the horsepower ofthe skid steer being used and the size of the profiler.It is
recommended for maximum performance that you start at approximately 19-25mm in concrete
and 38-50 mm in asphalt.
5. With the engine at full RPM and the profiler rolled back, lower the loader arms completely down
and slowly roll out the profiler until the weight ofthe profiler isresting on the rear wheel
assemblies. Continue to exert down pressure by rolling the loader forward until the front wheels
of the profiler areon the ground and the front wheels ofthe skid steer areraised approximately
50-75mm off the planing surface to assure sufficient pressure for stable operation.
NOTE: It is recommended to try a sample cut until the desired depth isachieved.
6. Slowly advance forward.
NOTE: If drum stalls you have been traveling too fast or cutting too deep. Back out ofthe cut until the
drum restarts (make necessary adjustments) and then continue operation.
NOTE: If the drum tends toride up out ofthe cut, decrease travel speed, be sure the profiler islevel
(front toback) and exert down pressure until the profiler isriding on the wheel assemblies. For
optimal cutting and reduced vibration, maintain down pressure on the profiler with all four profiler
wheels on the ground when cutting.
NOTE: Avoid side to side movement while planing as this may cause excessive drum wear or
planetary failure.
7. When you have reached the end ofthe pass, stop the skid steer and raise the profiler out ofthe
cut. Reposition skid steer for the nextcutand repeat steps 4, 5 & 6. Ifyouare not starting a
new cut, raise the profiler and retract the drum into the profiler housing using the depthcontrol
cylinders. Do not transport the profiler with drumturning.

OPERATING INSTRUCTIONS
SPECIAL APPLICATIONS
LARGE AREA
DIGGA’S independent depth control design allows for continuous milling. Instead of planing pass
1,3, 5 and then going back and resetting the profiler for passes 2 and 4, the DIGGA profiler allows
for individual depth control from the operator's seat to enhance performance and continually mill
large areas.
MILLING AROUND MANHOLES
For bestvisibility when milling around
manholes itisrecommended that the
planer be shifted tothe right. The profiler
is not designed tomill around tight
corners, therefore itisrecommended that
four tosix passes be made on each side
of the manhole.
NOTE: The more passesthe less amount
of manual clean-up required.
