HYDRAULIC SYSTEM HOOK-UP INSTRUCTIONS
M-1653 2-15-18-2
GENERAL INFORMATION
Once the installation instructions are complete, you are now ready to make the hydrau-
lic connections necessary to operate your earth drill.
READ AND UNDERSTAND SAFETY INFORMATION PRIOR TO
MAKING HYDRAULIC CONNECTIONS.
Your equipment dealer is in the best position to advise you as to where the best place
on your machine is to make the hydraulic connections to power your earth drill drive unit. The
list below shows the most common places to “tap” into the hydraulic system on various types
of machines.
• SKID STEER LOADERS - Auxiliary hydraulic outlets.
• BACKHOES & EXCAVATORS - Auxiliary hydraulic outlets or bucket curl cylinder circuit.
• WHEEL LOADERS & TRACTOR LOADERS - Auxiliary hydraulic outlets or bucket tilt
(dump) cylinder circuit.
Determine the length of hydraulic hoses required to plumb drive unit into the place on
your machine where you will be “tapping” into the hydraulics. Be sure the two hydraulic hoses
are long enough to perform at the full range of the earth drill’s operating capacity. A case drain
line will also be required to operate your earth drill.
• Models X4075, X5075, X6075, X8075 & 8K2 - These models require two 3/4” (19mm) ID
hydraulic hoses, with #12 JIC Female ttings on one end of each hose, to connect hoses to
drive unit ttings. A case drain line is also required. The skid steer hydraulic kits for the high
torque auger drives include a case drain line. An excavator Drain Line Kit is available through
your local dealer.
NOTE: Fittings on the other end of each hydraulic hose should match the threads on the hy-
draulic quick couplers to be used.
WARNING! HOSES AND FITTINGS MUST HAVE A CONTINUOUS OPERATING PRES-
SURE RATING OF AT LEAST 25% HIGHER THAN THE HIGHEST PRES-
SURES OF THE SYSTEM YOU ARE “TAPPING” INTO.
Once all of the hydraulic connections have been made and checked for leaks, you are
now ready to operate your earth drill. READ AND UNDERSTAND OPERATING INSTRUC-
TIONS AND SAFETY INFORMATION PRIOR TO OPERATING YOUR EARTH DRILL.

75623

OPERATING INSTRUCTIONS
M-1735 11-15-13-2
All three auger drives dig the same except the 8K2 has an additional two speed “shift on de-
mand” feature.
8K2 TWO SPEED AUGER DRIVE:
An increased demand on the auger drive will cause the pressure of the operating vehicle to in-
crease. When the pressure of the prime mover exceeds 2500 PSI (preset) the 8K2 motor will automati-
cally shift to maximum displacement, which reduces the speed of the auger and increases the torque.
When the pressure decreases and goes below 1000 PSI the motor will shift back to minimum displace-
ment which will increase the speed of the auger and decrease the torque.
OPERATION
1. After all installation instructions have been completed, safety information read and understood,
and the rest of this operator’s manual has been reviewed, your McMillen Hydraulic Earth Drill is
now ready for use.
2. With the auger raised off the ground and the vehicle engine set at a low RPM, activate the earth
drill control valve to determine which position the control valve lever must be in to turn auger in
a forward (clockwise) rotation. This is the “digging” position.
3. Before beginning to dig, experiment with auger speed to determine a suitable auger RPM. Gen-
erally in light and sandy soil a high RPM is desirable. In hard, rocky, or frozen soils a slower
RPM is desirable. To increase auger RPM, increase vehicle engine RPM. To decrease auger
RPM, decrease vehicle engine RPM.
4. Return earth drill control valve to neutral position to stop the auger. Lower the auger to the
ground so that only the center point penetrates the ground about 2” (51mm).
5. Activate the earth drill control valve so auger is turning in a forward (clockwise) rotation. Use
only enough down pressure to assure positive penetration of auger into the ground. Ease up on
down pressure if auger rotation slows down drastically or stalls.
NOTE: Excessive down pressure will cause the auger to stall frequently.
6. When auger has penetrated the ground about 24” (610mm), raise the auger from the hole to
clean the dirt out. Repeat this procedure until the desired hole depth is obtained.
7. Once the required hole depth is reached, allow the auger to turn a few seconds at this depth to
clean the hole.
8. Return the earth drill control valve to the neutral position to stop the rotation of the auger. Raise
the auger out of the hole, move away from the hole, then activate the earth drill control valve to
spin the loose soil off of the augers.
NOTE: Do not reverse the auger rotation to remove from the hole as loose soil on the auger
ights will fall back into the hole.
75623
15

OPERATING INSTRUCTIONS
M-1736 11-15-13-2
9. If necessary, repeat steps 7 & 8 to obtain a cleaner hole.
10. In some soil conditions or when excessive down pressure is applied, auger may “screw” itself
into the ground and become stuck causing earth drill to stall. If this happens, reverse the auger
rotation (counter-clockwise) by moving the control valve lever to the reverse position and slowly
raise the auger. Once unstuck, return the control valve lever to the forward rotation position and
continue digging.
11. If the auger becomes lodged under rocks, roots, or other large obstructions, do not attempt to
raise the auger out of the ground. See step 10 for proper procedure to relieve the auger.
12. Avoid excessive side loading to earth drill which can cause drive unit or auger damage.
13. Keep auger teeth and points in good condition. Check frequently and always keep spares on
hand so they can be replaced as wear is detected to avoid damage to tooth holders and auger
ighting.
WARNING: To prevent possible injury or death, keep all bystanders 10 feet or more away from
rotating auger. Take extra precautions when digging in locations where any type
of landscape fabric may be present.
STORAGE
• Check that drive unit motor and hoses are full of clean oil and planetary is full.
• Coat liberally with grease the output shaft and collar, extension shaft and collar, and all connecting
pins to prevent rust and reduce wear.
• Clean the unit thoroughly, removing all mud, dirt, and grease.
• Inspect for visible signs of wear, breakage, or damage. Order any parts required and make the nec-
essary repairs to avoid delays upon removal from storage.
• Tighten loose nuts, capscrews and hydraulic connections.
• Seal hydraulic system from contaminants and secure all hydraulic hoses off the ground to help pre-
vent damage.
• Replace decals that are damaged or in unreadable condition.
• Store unit in a dry and protected place. Leaving the unit outside will materially shorten its life.
Additional Precautions for Long Term Storage:
• Touch up all unpainted surfaces with paint to prevent rust.
REMOVAL FROM STORAGE
• Remove cover.
• Wash unit and replace any damage and/or missing parts .
• Check hydraulic hoses for damage and replace as necessary.
