GENERAL INFORMATION
GUARDA R CORPORAT ON’S A R-SPADE Series 2000 is a compressed air-powered tool
used for excavation of a wide variety of soils. A R-SPADE Series 2000 consists of an
ergonomic pistol grip style handle, an insulated fiberglass barrel, and a patented
supersonic nozzle. Typically powered by a portable tow-behind air compressor, the
A R-SPADE Series 2000 provides a safe, powerful and efficient method of uncovering
underground electric lines, pipes, and tree roots without harm. Capable of excavation
where a shovel or backhoe cannot be used, A R-SPADE can be equipped with multiple
nozzle sizes and a variety of extension lengths for optimum job performance.
The heart of the A R-SPADE is the patented supersonic nozzle which produces a focused
“laser-like” jet of air moving at approximately 1,200 mph (1,900 km/hr), or nearly twice
the speed of sound. This supersonic air-jet penetrates voids in the soil and expands
rapidly, therefore fracturing the soil. Unlike the hard cutting edges of shovels, picks,
blades, or buckets, the air-jet is harmless to non-porous items such as tree roots,
buried pipes, or cables. Excavating with A R-SPADE is much easier and many times
faster than hand excavation.
The A R-SPADE supersonic air-jet outperforms “homemade tools” featuring a pipe
nipple or a crimped orifice. Air flow from these tools expands to atmosphere in an
unfocused, complex manner while the supersonic air jet delivers significantly more
kinetic energy and more focused momentum. n practical terms the A R-SPADE does
more work by moving more material, and harder material, in a shorter period of time.

A R-SPADE’s patented supersonic nozzle turns compressed air into a high speed,
laser-like jet moving at twice the speed of sound – 1,200 mph. All of the energy
and momentum of air moving at approximately Mach 2 is focused into the soil,
dislodging it in a fraction of a second. (Fig.A) The result is faster, safer, and more
efficient soil excavation.
Air exiting from an improperly designed nozzle diffuses outward 3 to 4 times wider
than the air-jet from the patented A R-SPADE supersonic nozzle. (Fig.B)

SAFETY INSTR CTIONS
… Wear appropriate protective work clothing and equipment. Cut and puncture
resistant gloves, approved safety glasses with side shields and/or face protec-
tion, and approved hearing protective earplugs or earmuffs should be worn
while operating the A R-SPADE. Eye protection should comply with
ANS Z87.1-1989. Ear protection should provide a NRR of at least 20 dB.
… Wear approved respiratory protection when working in extremely dusty
conditions.
… Wear approved, electrically insulated footwear and gloves if working near
underground electrical lines.
… Ensure that all personnel near the area being excavated are aware that
A R-SPADE is being used and that they wear appropriate personal protection
as indicated.
… Protect surfaces that could be chipped, or damaged by dislodged soil or rock
particles adjacent to the excavation work area by using suitable drop cloths,
screens, or other means.
… Check the A R-SPADE for loose or damaged parts prior to use.
Tighten, repair, and/or replace as necessary.
… Inspect hoses for leakage, kinking, abrasion, corrosion, or any other signs
of wear or damage. Worn or damaged hose assemblies should be replaced
immediately.
… Check that the air compressor is delivering the specified pressure to operate
the A R-SPADE.
… Anticipate that the A R-SPADE tool will push upwards when using the 45
degree adapter. Brace against the upwards force by holding the tool in
accordance with the operating instructions.

SAFETY INSTR CTIONS
… Operate the A R-SPADE until the operating and safety instructions
are read and fully understood.
… Make any modifications to the A R-SPADE.
… Tie, tape, or otherwise lock or fasten the trigger in the “ON” position.
… Point, or aim the A R-SPADE at any person during operation.
… Allow hands, feet, or any body parts near the A R-SPADE nozzle tip
during operation.
…Use the A R-SPADE as a pry bar.

User assumes full responsibility to read and understand these
instructions prior to operation. Failure to adhere to these instruc-
tions can result in personal injury. User should also have operat-
ing knowledge of the air-compressor to which the tool is attached.

HANDLE
•Read and follow the directions below to properly assembly the A R-SPADE.
•Apply a small amount of commercial grade anti-seize compound on the barrel
threads (A & B) to prevent galling. Screw the nozzle into the barrel by turning
clockwise. Hand-tighten only.
•Screw the barrel into the handle by turning clockwise. Hand-tighten only.

TARTING
•Start the air compressor according to the manufacturer’s instructions.
•The air compressor should build pressure until 100 – 120 psig is shown on the air
compressor pressure gauge.
•Make sure that A R-SPADE is turned off. Point the nozzle away from all personnel
or loose objects that could become airborne. Open the air supply valve on the
air compressor.
•Securely hold the A R-SPADE. Point the nozzle up and away from all personnel and
any loose objects, and depress the trigger. Read the air compressor pressure gauge
and the pressure gauge on the tool. During operation the air pressure gauge on the
tool should read between 80 and 100 psig (5.5 and 6.9 bar). f not, adjust the output
pressure of the air compressor.
•Match the air compressor size to the A R-SPADE nozzle on the tool. To properly size
the air compressor, make sure the air compressor flow rate is equal to, or greater
than, the nozzle flow rate.
•Check the air compressor for sufficient fuel and oil levels.
•Make sure the air compressor is secure from accidental motion.
•Close the air supply valve on the air compressor.
•Make sure all air supply hose
connections are securely
made and safety clips
are installed.
•Use air supply hose with a
pressure rating equal to, or
greater than, 150 psig.
•Use air supply hose of an
appropriate diameter and
length. (See Table)

EXCAVATION PROCEDURE
•For most excavations the best performance is achieved by holding the A R-SPADE
nozzle at approximately a 45 degree angle from horizontal and about 1 inch away
from the surface to be excavated.
•Depending on the soil type, the A R-SPADE should be directed above the surface
to be excavated at a rate of approximately 1 to 2 feet per second
(0.3 to 0.6 meters per second).
•Except in very hard and compacted clays, dwelling on the same spot tends to reduce
the rate at which material is excavated and can increase the amount of material
blown away from the excavation site.
•Watering the work area ahead of time can often be helpful. Watering reduces
airborne dust if the soil is extremely dry. t also reduces the soil strength making
digging easier.
•For small diameter holes, position the A R-SPADE barrel perpendicular to the ground
with the nozzle close to the surface. Depress the trigger, and slowly thrust the tool into
the soil. When resistance is met, slowly withdraw the A R-SPADE and then reinsert.
This procedure allows loose soil at the bottom of the hole to exit upwards. Reinsert
the nozzle and repeat the above procedure until the desired depth of hole is reached.
•When boring a small diameter hole, or when plunging the A R-SPADE into loose soil,
the tendency to expose the operator to blown back material is increased. The ad-
justable dirt shield should be positioned close to the ground to deflect airborne
material away from the operator.
•For large diameter holes, position the A R-SPADE at an angle between 30° and 45°
from the horizontal. Depress the trigger and move the A R-SPADE back and forth
across the footprint of the excavation to loosen the soil to a depth of several inches.
Each layer of loose soil should then be removed with a shovel, backhoe, or vacuum.
Repeat the procedure until the desired depth is reached.
•For shallow, wide excavations, position the A R-SPADE at an angle between 30° and
45° from the horizontal. Depress the trigger, move the nozzle from side to side the
desired width, and blow the loosened soil ahead of the nozzle. Continue until the
excavation is completed to the required length.
