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
WARNING
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.
WARNING
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
WARNING
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.
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.
