Profila Operator’s Manual Safety 6
WARNING! Escaping fluid under pressure can have sufficient force to
penetrate the skin causing serious personal injury. Fluid escaping
from a very small hole can be almost invisible. Use a piece of
cardboard or wood, rather than hands to search for suspected
leaks.

Keep unprotected body parts, such as face, eyes, and arms as far away as possible
from a suspected leak. Flesh injected with hydraulic fluid may develop gangrene or
other permanent disabilities.
If injured by injected fluid, see a doctor at once. If your doctor is not familiar with this
type of injury, ask him to research it immediately to determine proper treatment.

disconnect the planer from your skid-steer allowing the mounting
bracket to lower toward the ground as the skid-steer is disengaged.
8. Connect the hydraulic couplers on the attachment together to prevent
contaminants from entering the hydraulic system.
GENERAL INFORMATION
The DIGGA planer 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 planer.
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 planer 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 planer. Best performance is obtained
when the Profila 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: The optional wheel assemblies may be removed when distance is
a factor such as milling next to an obstacle or building.
OPERATING INSTRUCTIONS
1. Clear area of all bystanders.
2. Lift the planer until the drum is off the ground and start planer rotation.
(Teeth at the bottom of the drum must be moving in the same forward
direction that the planer travels.)
NOTE: Mill only when the skid-steer is traveling forward. Do not operate
when traveling in reverse.
NOTE: Hydraulic cylinders tilt the planer, adjust the depth of both the
left and right side of the planer individually, and also shift the planer to
the left or right.
3. Increase engine RPM and with the drum turning you can make any
necessary adjustments to the side shift. Do not side shift the Profila 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 planer.
Profila Operator’s Manual Installation Instructions 13

4. Position the planer at the desired starting point. Set the left and right depth
gauge to the desired depth mark on the planer. Maximum depth of each cut is
determined by the type of material, the horsepower of the skid-steer being
used and the size of the planer. It is recommended for maximum performance
that you start at approximately .75" to 50mm in concrete and 1.50" to 100mm
in asphalt.
5. With the engine at full RPM and the planer rolled back, lower the loader
arms completely down and slowly roll out the planer until the weight of the
planer is resting on the rear wheel assemblies. Continue to exert down
pressure by rolling the loader forward until the front wheels of the planer are
on the ground and the front wheels of the skid-steer are raised approximately
2-3 inches off the planing surface to assure sufficient pressure for stable
operation.
NOTE: It is recommended to try a sample cut until the desired depth is
achieved.
6. Slowly advance forward.
NOTE: If drum stalls you have been traveling too fast or cutting too
deep. Back out of the cut until the drum restarts (make necessary
adjustments) and then continue operation.
NOTE: If the drum tends to ride up out of the cut, decrease travel speed,
be sure the planer is level (front to back) and exert down pressure until
the planer is riding on the skids/wheel assemblies. For optimal cutting
and reduced vibration, maintain down pressure on the planer with all
four planer 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 of the pass, stop the skid-steer and raise
the planer out of the cut. Reposition skid-steer for the next cut and repeat
steps 4, 5 & 6. If you are not starting a new cut, raise the planer and retract
the drum into the planer housing using the depth control cylinders. Do not
transport the planer with drum turning.
Periodic observation must be made of the
transmission oil temperature indicator when planing
with high flow hydraulic systems.
Profila Operator’s Manual Installation Instructions 14
Depending on the ambient temperature and the duty
cycle of the machine, hydraulic oil may overheat.
If indicator comes on, shut off the Profila and allow
the skid-steer to idle until the temperature falls below
160° Fahrenheit.
If the system continues running hot it may be
necessary to clean any debris from the oil cooler and
radiator. Check engine air filter and also the hydraulic
oil level.

Continuous or excessive overheating may cause machine damage.
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 planer
for passes 2 and 4, the DIGGA planer allows for individual depth control from
the operator's seat to enhance performance and continually mill large areas.
MILLING AROUND
MANHOLES
For best visibility when milling
around manholes it is
recommended that the planer
be shifted to the right. The
planer is not designed to mill
around tight corners, therefore
it is recommended that four to
six passes be made on each
side of the manhole. NOTE:
The more passes the less
amount of manual clean-up
required.
DEEP CUTS
To achieve a deep cut the width of the drum, make the first cut at the
recommended depth for the material being milled and then reposition the
planer at the beginning of the pass and reset for double the recommended
depth. Example: Make the first cut with the depth controls set at 100mm and
then set the depth control at 100mm for the second pass and so on and so
forth until the desired depth is obtained.
Profila Operator’s Manual Installation Instructions 15

To achieve a 150mm cut of a large area it is recommended to cut the entire
area at the recommended depth and then clear the spoil from the area before
making the second cut.
Removing the spoil between cuts will enhance the productivity of the planer
and maintain an even cut.
If trying to achieve a critical cutting depth it is recommended that the spoil
from one cut be cleared away before making another pass. This will eliminate
the possibility of the planer riding on and off the spoil and creating an uneven
surface.
MILLING TAPER CUTS
When adding to or joining new paved surfaces to existing paving, a taper cut
may be required at the interacting joints so the new paving would appear
seamless. See the chart below for the angle of cut per size of Profila.
Example: To achieve a taper cut from 0 to 100mm over a 1200mm distance with
a 600mm wide Profila it is recommended that you set one side of the planer at
100mm and the other at 100mm and the tilt set at 4° for the first pass. Then
make a second pass with both sides of the planer set at 0mm and the tilt still at
4°.

8MaintenanceandService
GENERAL INFORMATION
Economical and efficient operation of any machine is dependent upon regular
and proper lubrication of all moving parts with a quality lubricant. Neglect
leads to reduced efficiency, wear, breakdown and needless replacement of
parts.
All parts provided with grease fittings should be lubricated as indicated. If any
grease fittings are missing, replace them immediately. Clean all fittings
thoroughly before using the grease gun.
IMPORTANT: Avoid excessive greasing. Dirt collects on exposed grease
and greatly increases wear. After greasing, wipe off excessive grease
from fittings.
LUBRICATION SYMBOLS
Profila Operator’s Manual Maintenance and Service 17
The following symbols are used on the lubrication diagram below. It is
reproduced here with its meaning for your convenience.
Lubricate daily or every 8 hours of operation, whichever comes last,
with SAE Multi-Purpose Lubricant or equivalent SAE Multi-Purpose
type grease.
Lubricate weekly or every 40 house of operation, whichever comes
last, with SAE Multi-Purpose Lubricant or equivalent SAE Multi-
Purpose type grease.
CAUTION! SHUT OFF ENGINE BEFORE LUBRICATING
EQUIPMENT.
The planer planetary is a sealed unit. If there is any sign of oil leaks
please contact your nearest DIGGA dealer before carrying out any repairs, as
there can be other causes for seal leaks. The planetary uses the Gear Oil
(Castrol SP 320) for lubrication of gears and bearings. The unit holds
approximately 2 quarts of gear oil.
The planetary gear oil should be drained and replaced after the first 8 months
of use. Thereafter every 12 months or 2500 hours - whichever comes first.

GENERAL INFORMATION
Regular maintenance is the key to long equipment life and safe operation.
Maintenance requirements have been reduced to an absolute minimum. However it
is very important that these maintenance functions be performed as described below.
Never do any maintenance to the planer while it is running.
Exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE
BEFORE working on or around the planer.
DAILY
• Check to be sure case drain coupler is completely engaged.
• Check skid-steer hydraulic system to ensure an adequate level of hydraulic oil.
• Check all hardware and tighten if necessary. See Section "O" for Bolt Torque
Specifications.
• Check hydraulic system for hydraulic leaks.
• Check for missing or illegible Safety / Warning Decals.
• Check picks for freedom of rotation, flat spots and wear. Replace worn or missing
picks or any picks that are not rotating freely or have flat spots.
• Visually inspect the machine for worn parts or cracked welds and repair as
necessary.
• Lubricate grease fittings on Wheel pivot pins.
EVERY 40 HOURS
• Lubricate grease fittings on cylinder ends and front of planer.
