OPERATING INSTRUCTIONS
INTENDED USE:
This unit is designed to plane / 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
P
rofiler
attaches to the toolbar/quick-attach mechanism of your skid steer loader. Due to
this arrangement, thorough knowledge of the skid steer controls is necessary for machine operation.
Read and understand your skid steer operator's manual for information regarding skid steer
operation before attempting to use the p
rofiler
. Check the surface to be planed. The standard all
purpose picks can be used to mill both asphalt and concrete. There are optional concrete picks that
are recommended if the p
rofiler
is to 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 of the cut, and also the side shift position of the p
rofiler
. Best performance is
obtained when the
road profiler
is in 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 next to an 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 P ROFILER OR OF ANY ATTACHMENT
THAT MAY CAUSE HIGH LEVELS OF DUST.
