Safety Precautions
LETHAL EXHAUST GAS: An internal
combustion engine discharges carbon
monoxide, a poisonous, odorless, invisible
gas. Death or serious illness may result if
inhaled. Operate only in an area with proper
ventilation. NEVER OPERATE IN A
CONFINED AREA!
DANGEROUS FUELS: Use extreme caution
when storing, handling and using fuels, as
they are highly volatile and explosive in vapor
state. Do not add fuel while engine is running.
Stop and cool the engine before adding fuel.
DO NOT SMOKE!
SAFETY GUARDS: It is the owner's
responsibility to ensure that all guards and
shields are in place and in working order.
IGNITION SYSTEMS: Breakerless, magneto,
and battery ignition systems can cause severe
electrical shocks. Avoid contacting these
units or their wiring.
SAFE DRESS: Do not wear loose clothing,
rings, wristwatches, etc. near machinery.
HEAD PROTECTION: Wear OSHA specified
safety helmets.
DUST PROTECTION: Wear OSHA specified
dust mask or respirator.
OPERATOR: Keep children and bystanders
off and away from the equipment.
REFERENCES: For details on safety rules and regulations
in the United States, contact your local Occupational Safety
and Health Administration (OSHA) office. Equipment
operated in other countries must be operated and serviced
in accordance and compliance with any and all safety
requirements of that country. The publication of these
safety precautions is done for your information. MBW does
not by the publication of these precautions, imply or in any
way represent that these are the sum of all dangers present
near MBW equipment. If you are operating MBW
equipment, it is your responsibility to insure that such
operation is in full accordance with all applicable safety
requirements and codes. All requirements of the United
States Federal Occupational Safety and Health
Administration Act must be met when operated in areas that
are under the jurisdiction of that United States Department.
Safety Decals
Carefully read and follow all safety decals. Keep them in
good condition. If decals become damaged, replace as
required. If repainting the unit, replace all decals. Decals
are available from authorized MBW distributors. Order the

OPERATION
This parts manual contains only standard parts. Variations
of these parts as well as other special parts are not included.
Contact your local MBW distributor for assistance in
identifying parts not included in this manual.
Before Starting & Operating
• REMEMBER! It is the owner’s responsibility to
communicate information on the safe use and proper
operation of this unit to the operators.
• Review ALL of the Safety Precautions listed on page 1 of
this manual.
• Familiarize yourself with the operation of the machine
and confirm that all controls function properly.
• Know how to STOP the machine in case of an
emergency.
• Make sure hands, feet, and clothing are at a safe
distance from any moving parts.
Connecting to Air Compressor
For proper operation, the air supply must deliver the volume
and pressure required for the Soil Pick model being used.
Refer to Specifications, page 3 for minimum requirements.
1.Start compressor and check pressure gage to verify
proper operation of the compressor.
2.Connect air hose to compressor outlet and install
safety clips if required.
3.Connect air hose to Soil Pick coupler and install
safety clips if required.
4.Open compressor valve to pressurize Soil Pick.
Starting Soil Pick
Do not operate the Soil Pick at a pressure greater
than 125 psi.
4.Adjust the rubber deflector so the bottom of the cone
is about three inches (3”) above the nozzle tip.
Operating
Always wear safety goggles and hearing
protection when operating Soil Pick.
1.If the area to be excavated is covered with grass or
other plant material, it may be easier to remove it with
a shovel or rake before proceeding with the Soil Pick.
2.Hold the Soil Pick perpendicular to the soil surface to
be worked.
3.With the nozzle in contact with the soil, pull the trigger
momentarily to break up the soil in immediate contact
with the nozzle tip.
4.While keeping the nozzle submerged in the loosened
soil, hold the trigger down and work the nozzle in a
circular motion.
5.As the soil is loosened and the Soil Pick is worked
deeper into the ground, move the deflector up the
barrel to minimize scatter.
6.After loosening the soil, it can be easily removed
using an industrial vacuum system or using
conventional methods.
Stopping Soil Pick
1.Close compressor valve to release supply pressure
to Soil Pick.
Never aim the Soil Pick at exposed skin or people.
1.Aim Soil Pick away from people, and pull the trigger.
2.If the pressure reading is less than 100 psi (indicated
as a red section on some gages), the air pressure at
the source must be increased.
3.If the pressure reading is greater than 125 psi, the air
pressure at the source must be decreased to prevent
damage and possible injury.
2.Aim Soil Pick away from people, and pull the trigger
to relieve all residual air pressure in the hose.
3.Disconnect air hose on both ends.
4.Turn compressor OFF.
5.Slowly open compressor valve to relieve air pressure
in the tank.
Tips & Tricks
1.The Soil Pick can be used alone for safe excavation
on small jobs, or used as an underground locating
and exposing tool in conjunction with higher
production excavators, backhoes, and trenchers.
- 4 -
2.The Soil Pick is not an elaborate blow pipe.
Conventional blow pipes produce subsonic air
stream velocities between 500 and 600 mph, and
cannot provide the cutting edge required for soil
excavation. Blow pipes can be used for moving loose
debris, but even then are outperformed by the Soil
Pick.
3.The Soil Pick is a selective excavator. The violent
decompression of air is sufficient to loosen porous
soil, but will have virtually no effect on non-porous
objects such as buried utilities or plant roots.
4.The Soil Pick has a cutting edge of four to eight
inches, depending on the model. This means the
nozzle must be kept close to the soil for the
decompression to be effective. Beyond the cutting
edge, substantial decompression has occurred and
the Soil Pick becomes a highly effective blower for
loose debris.
5.The Soil Pick will not cut through frost, but it will work
well below the frost line.
6.The Soil Pick works extremely well in all types of
granular soils and cohesive soils with a good granular
gradation. The effectiveness will drop off as the
granular component in cohesive soils decreases.
Wet clay soils may be too plastic to loosen.
7.The Soil Pick does not require lubrication. The air
supply must be free of oil to achieve proper
performance.
8.The Soil Pick is not designed as an impact or prying
tool. The barrel is manufactured of a composite
material designed to withstand high internal
pressure. It is not designed to withstand prying or
impact forces.
9.The Soil Pick is an effective excavation tool even
when there is no concerns of buried utilities. In most
cases, productivity is enhanced dramatically
compared to pick and shovel work.
10. The Soil Pick is highly effective when used to clean
saw joints and cracks in concrete. It can grossly
outperform a blow pipe, and provide a very clean
surface for excellent sealant adhesion.
11. The Soil Pick is an effective tool for nursery
applications. Because it is a selective excavator, it
will not damage roots. Because it is an air tool, it is
also aerating the soil while digging.
12. The Soil Pick has an almost endless list of uses. It
can effectively clean barges, railroad cars,
construction equipment, and more. It can be used for
shallow trenching, post hole digging, stump removal,
pothole preparation prior to patching, and many more
unique applications.

SERVICE
Assembly and disassembly should be performed by a
service technician who has been factory trained on MBW
equipment. The unit should be clean and free of debris.
Pressure washing before disassembly is recommended.
• Prior to assembly, wash all parts in a suitable cleaner or
solvent.
• Check moving parts for wear and failure. Refer to the
Replacement section in this manual for tolerance and
replacement cycles.
• All shafts and housings should be oiled prior to pressing
bearings. Also, ensure that the bearings are pressed
square and are seated properly.
• All bearings should be replaced when rebuilding any
exciter or gearbox.
• All gaskets and seals should be replaced after any
disassembly.
