cles at high velocity and striking the operator and/or onlookers. This can result in property damage and/
or personal injury.
• Do not utilize any objects to remove loose soil in or around the hole area while the EDCO 2PH is in
use. Said object could become entrapped in rotating auger, leading to property damage and/or personal
damage.
• Always hold the operators handles firmly. Always determine handle bars and grips are in good working
condition and free of dirt/oil/grease/moisture. Never leave EDCO 2PH running unattended.
• Starting the EDCO 2PH should occur in the following process: Team leader regulates the engine speed
with the throttle control, while the team member starts the engine with the recoil starter. The team lead-
er is responsible for the verbal commands. Never operate the EDCO 2PH if it requires one person to be
responsible for all functions of the engine. This will result in loss of machine control leading to property
damage and/or personal injury.
• The EDCO 2PH is designed for two operators; (1) team member, to operate the recoil starter and the
choke control. (1) Team leader is responsible for throttle control regulation. (See figure 3)
• The EDCO 2PH operates by engaging the throttle control lever which in turn allows for the engine to
increase RPM that engages the featured centrifugal clutch, which only rotates at a designed speed.
The engine at idle will not engage the centrifugal clutch, meaning the auger will not rotate. If the throttle
control lever is not engaged the machine will not rotate.
• Stop engine with on board ON/OFF switch between each hole. Allowing the engine to operate between
each hole increases potential for property damage and/or personal injury.
• The EDCO 2PH is limited in the number of practical and/or suitable job applications. Site, surface con-
ditions, specifications and operator skill may dictate the need for a different type of machine/method to
achieve success while remaining safe.

Starting the Machine Once the Auger
has Been Attached
Be sure the auger teeth and screw tip are not clogged. Removal of any obstructions before starting
the engine and digging operation will increase the effectivity of the auger and auger attachments
during use.
Place the EDCO 2PH in a vertical position over the desired hole location. Ensure both operators
have firm stances before starting the machine.
During all starting operations and processes ensure that at least three positions of the machine
are being supported by team member and team leader. At times during the starting process it is
required that the team member, has one hand completing an operation (choke, on/off, fuel valve)
and one hand on a handle bar. The team leader is required to maintain a majority of the stability of
the machine during these processes. Once the team member completes said operation, they are
responsible for replacing their hand on to the handle bars.
To Start:
1. Team member: open the gasoline breather to its most open position to ensure a continuous
steady flow of fuel. (See figure 4)
2. Team member: turn ON the engine kill switch. (See figure 5)
3. Team member: engages the choke control if required during cold starts. (See figure 6)
4. Team member: utilizes recoil starter to start the engine. If completing cold start, allow engine to
warm up before disengaging choke.
5. Team leader: operates the throttle control lever and provides stability during the starting opera-
tion.
DANGER! At NO time should the team leader begin engaging the throttle control lever until both
team leader and team member have all four handle bar positions supported. Before engaging the
throttle, ensure both team member and team leader have acknowledged to each other they have
full control and are ready to begin digging. Failure to comply, can result is personal injury and/or
property damage.

Digging
EDCO does not warranty or guarantee that this machine is suitable for specific job applications and
that it will have the required power to dig a specific diameter hole to a certain depth in a specific soil
type.
Before attempting to dig with the hole digger, determine any potential subsurface hazards which
may exist in the proposed digging location(s) including but not limited to: Rocks, roots, buried mate-
rials, pressurized pipes, electrical cables.
DANGER! Always contact your appropriate local agencies to determine exact locations of all buried
utilities and subsurface hazards. If the EDCO 2PH comes in contact with any subsurface hazard,
property damage and/or personal injury will occur.
The EDCO 2PH is designed to be operated and transported on/around the jobsite by two people.
Connect the auger to EDCO 2PH with the factory supplied clevis pin. When installing the clevis pin,
ensure the EDCO 2PH is tilted with the spark plug facing away from the surface, preventing oil and/
or gasoline to enter the combustion chamber causing a hydraulic lockup.
Do not connect the auger to the EDCO 2PH while the engine is running.
The factory supplied clevis pin is designed to withstand high stresses encountered under normal
digging operations. Use of any other connecting device including screws, bolts, pins, etc. can cause
property damage and/or personal injury.
Normal operation of the EDCO 2PH involves a large value of torque being transmitted and multiplied
within the gearcase/transmission. This energy is required to dig holes this machine is said to accom-
plish. In physics, there is always an opposite force to every force. Thus, if the auger encounters an
unknown or known obstruction this force will be transmitted to its stationary position (the operators).
The operators will feel a thrust of force, relative to the speed the auger is rotating, once the auger
has encountered said obstruction. This thrust of force is unavoidable while utilizing an EDCO 2PH.
To offset the velocity of forces felt during the immediate thrust of energy to the handle bar when en-
countering an obstruction, the operators should position themselves as close as possible to their left
handle bar. Keep upper arms as close to the upper body as possible to maximize mechanical body
leverage. Keep operators body and back in a most vertical posture as possible and always bend
at the legs to accomplish the digging operation. Avoid placing serious strains to the back and other
body members. Always lift in a straight line with your legs. Maintain vertical back posture. Avoid
bending wrist during the digging process.

Digging Continued
Positioning the left foot ahead of the right foot will increase the body leverage during the digging opera-
tion.
Maintain a steady and firm grip on the operator handle bars at all times.
CAUTION! Maintaining all of the above proper operating positions and operating controls is the most
important aspect to effective EDCO 2PH operation. Operator fatigue will occur while operating the
EDCO 2PH, following the above guidelines will increase the timeframe of when operator fatigue will
begin to occur.
The physical makeup of the composite handle bars allow for the handle bars to dampen and absorb
some of the energy exerted from the thrust when the auger encounters obstructions.
CAUTION! Do not operate if the handle grips are worn/damaged. Replace any grips that show wear or
have holes in the end caps.
EDCO Augers are designed for digging a wide variety of soil types and conditions. In soft soil (moist
or sandy) it might be necessary to hold up on the handle bars to resist the machine from screwing the
auger in to the ground. In soils with higher proctor densities it may be required of the operators to apply
some downward force on the handles to establish and maintain productive digging rates.
Digging with small diameter augers sometimes causes the auger to bury/bind itself or screw in to the
surface. This causes the EDCO 2PH to exceed past the designed operating power and overload the
clutch. Do not continue to overload or slip the clutch as this causes excessive heat transfer in the
gearcase and clutch assembly. Failure to stop operation when the auger becomes stuck can result in
property damage and/or personal injury.
If an auger becomes stuck, power OFF the unit, disconnect and remove the EDCO 2PH from the au-
ger, then remove the auger manually by several different industry accepted methods.
Do not attempt to create a pilot drilled hole with the auger, then come back and ream the hole with a
larger diameter auger. This will cause for unstable digging operation. Failure to comply will result in
property damage and/or personal injury.

When digging holes where known obstruction are present, allow the auger teeth to chip away the ob-
struction until the auger can pass by working the obstruction loose. This is usually accomplished by
applying upward pressure to the operator handles. At times the obstruction is too large to remove with
the EDCO 2PH, continued use or attempts to remove the obstruction will result in machine damage and
increase operator fatigue. Instead, remove the auger and EDCO 2PH, then remove obstruction with a
shovel or other digging tool.
When retracting or removing the auger and EDCO 2PH after the desired hole depth has been achieved,
allowing the auger to slowly rotate will ease the removal of the auger. However, this will also leave some
soil to be manually removed from the bottom of the hole.
Stop the EDCO 2PH engine in between each hole. Failing to do so can cause property damage and/or
personal injury.
To stop/turn offthe EDCO 2PH:
1 - Team leader: Release the throttle control lever and allow the engine to idle. If the throttle is function-
ing properly the engine will go to idle speed and the clutch will disengage causing the auger to stop
rotation. If this does not occur, check the throttle control, throttle linkage and idle speed adjustment on
engine. There may be some auger rotation at idle speed due to drag in the clutch assembly. This does
not mean the clutch is engaged.
2- Team member: turn the ON/OFF engine switch to the OFF position. (See figure 8)
When you are done operating the machine, turn the fuel valve to the offposition (See figure 9) to mini-
mize the possibility of fuel seepage in to the combustion chamber. Property damage can occur if the fuel
valve is left open and the engine is tilted to allow fuel in to the crankcase.

Digging With an Auger Extension
Some applications require additional hole depth beyond the capabilities of a standard EDCO Auger.
This is accomplished by utilizing an EDCO auger extension. The addition of auger extensions re-
quire additional operator skill and common sense. Each operator must determine they are competent
enough to operate the EDCO 2PH with an auger extension attached.
1. Dig to the acceptable full depth of the standard auger. Remove as much of the soil from the hole
as possible.
2. Stop the EDCO 2PH, turn the fuel valve to the offposition. Disconnect the engine spark plug.
3. Place the unit back in to the dug hole.
4. Disconnect the EDCO 2PH from the standard auger and set aside on a level/horizontal surface,
leaving the auger in the hole.
5. Attach the auger extension to the auger that is located in the hole. Secure the auger extension with
the supplied clevis pin.
6. Install the EDCO 2PH to the auger extension.
7. Follow the instruction for starting and operating the EDCO 2PH. Extra caution and skill is required
to start an begin the continued digging with an EDCO 2PH starting in the existing hole.
There is a maximum allowable limit of one (1) auger extension when utilizing an EDCO 2PH. Failure
to comply will result in property damage and/or personal injury.
After the desired depth is achieved while using the auger extension, stop the engine, turn fuel valve
offand disconnect the spark plug.
1. Lift the EDCO 2PH and auger/extensions up far enough out of the hole so that the auger exten-
sion is above ground level. Utilizing blocking or auger fork supporting the standard length auger in the
hole.
2. Disconnect the EDCO 2PH from the auger extension and set the unit aside on a level, horizontal
surface. (This may require an additional team member to support EDCO 2PH and auger/extension)
3. Disconnect the auger extension from the standard length auger.
4. Then remove the standard length auger from the hole.
DANGER! Do not attempt to start the EDCO 2PH with an auger and auger extension attached out of
an existing hole. Always dig with the standard length auger first, then attach extension as prescribed
in the above text. If these instruction are not followed, property damage and personal injury will occur.

Maintenance
Always wear proper personal protective equipment while servicing or maintaining equipment. If
you are not competent in doing the work, please reach out to EDCO for advice or where you might
be able to have your machine serviced.
Changing the EDCO 2PH transmission oil (Interval: 25 hours)
The process requires a level working platform and appropriate working height surface. The EDCO
2PH can also be supported in a vise clamped on to the driveshaft.
1. The transmission oil should be changed as needed or at least every 25 hours of use.
2. Wipe any dust/dirt from the oil filler plug and area around the oil fill plug. Oil Fill is located on the
side of the gear case, while the oil drain is located on the lower portion of the gearcase near the
driveshaft. (See Figure 10)
3. Remove the fill plug using a 12 point, 1/2” socket to avoid stripping. Doing this while draining
the oil through the drain plug will allow for steady flow during the oil draining process.
4. Remove the drain plug with an 12 point, 1/2” socket and allow for oil to drain in to a suitable
container. Dispose of the oil based on local ordinances. Once oil has drained completely, replace
the oil drain plug securely.
5. Using a funnel, pour in 1 quart of oil (High Grade SAE 30 Motor Oil, EDCO #: 87042) in to the
EDCO 2PH transmission gear case oil fill hole. The oil fill hole is in a location designed to drain
any oil over the allowed 1 quart limit before replacing the oil fill hole. It is important to allow for any
excess oil to drain before reinstalling the oil fill plug.
6. Replace the oil fill plug securely.
Replacing Auger Screw Bit
Replace as required.
While replacing the screw bit, inspect the entire auger for cracks, bent axle or any other possible
damage before replacing parts.
1. Using two 1/2” wrenches, remove the screw and nut holding the screw bit to the drive lug. Re-
move the bit and dispose.
2. Inspect the drive lug, if drive lug needs replaced this can be cut offusing suitable cut offtools or
torch.
3. Replace Auger screw bit with new screw bit and hardware. Tightly fasten with wrenches.
Replacing Auger Teeth
Replace as required.
While replacing auger teeth, inspect the entire auger for cracks, bent axle or any other possible
damage before replacing parts.

Maintenance Continued
There are a multitude of auger teeth available on the market. All of them have different capabilities
and different lifespans. Most all of the teeth available are interchangeable across all manufacturers
of augers.
1. Using a hammer and punch, strike the rear of the tooth accessed through the shank plate teeth
access hole until the tooth has come dislodged from the shank plate.
2. Remove any residual rubber from the core of the tooth that may have stuck to the shank plate
over time.
3. Inspect the shank plate and the tooth cavity for any fatigue and wear. If required the shank plate
can be replaced.
4. Install new tooth in to the tooth pocket utilizing a soft tip mallet. Ensure tooth is completely seat-
ed in the pocket. Do not use metal hammer to accomplish this task.
Engine Maintenance and Troubleshooting
Consult the engine operators and owner’s manual for proper engine service and maintenance
manuals.
The engine ON/OFF switch (PN: 54004) located on the tan sheet bracket (PN: 101139) is are
EDCO parts and can only be purchased from EDCO.
The choke bracket (Honda: 16598-Z1V-G00, EDCO: 87011) and choke engage rod (Honda:
16611-Z1V-G00, EDCO: 87012) are Genuine Honda parts, however these parts can be purchased
through EDCO.
Ensure Engine ON/OFF switch and fuel valve are in proper positions based on the starting and
stopping instruction listed in this manual.
Troubleshooting EDCO 2PH
• Engine bogs down and will not rotate driveshaft upon engaging throttle: clutch is locked up or
seized
• Clutch engages at idle speed, or auger rotates at idle speed: Centrifugal clutch is worn out
• Clutch engages at idle speed, or auger rotates at idle speed: Throttle linkage is adjusted improp-
erly
• Clutch engages at idle speed, or auger rotates at idle speed: Engine idle speed is not set correctly
• Hole Digger is not digging or “lacking power” to accomplish task: Centrifugal clutch is worn out
• Hole Digger is not digging or “lacking power” to accomplish task: Auger diameter is too large for
soil

Maintenance/Repair/Storage/Transportation
Use only genuine, approved, replacement parts and accessories for replacement and repair.
Always properly maintain the EDCO 2PH. Check all fasteners and individual parts prior to every
operation. Designed safety features are only effective if they are maintained and in good working
order. All maintenance should be completed by a competent and trained technician or service facil-
ity. If proper maintenance is not performed, personal injury and/or property damage will occur.
Review the engine throttle control and throttle cable linkages and ensure they are not damaged and
allow for complete range of motion as designed.
Do not operate the EDCO 2PH with a faulty or damaged throttle control and throttle cable linkage.
If any decal becomes damaged and/or illegible, replace with genuine, factory replacement decals
only.
Replace the auger teeth and screw tip when signs of excessive wear become apparent. When
these components are not replaced, the boring head and auger flighting will begin to wear, causing
an inverted cone auger reducing productivity and potential property damage and/or personal injury.
The EDCO 2PH utilizes handle bars specially designed to reduce weight and help absorb the shock
loads transmitted to the operator during the digging process. This material is not as abrasion re-
sistant as steel and cannot handle the same amount of surface damage as steel. Do not allow the
handle bar material to come in to contact with sharp objects. Keep handles clean and free of dirt
and moisture.
Do not utilize chains or slings strapped around the handle bar material to help remove a stuck
EDCO 2PH. This will cause damage to the handle bar material and to the transmission.
EDCO 2PH handle bars have a maximum service life of 6 years.
DANGER! The composite handle bar material does not eliminate the potential for property damage
or personal injury if the machine is to contact an electrical cable.

Storage on the Jobsite (temporary)
There are three acceptable methods to storing the EDCO 2PH on the jobsite. If other methods
are used, property damage and/or personal damage will occur. Always store the machine with
the engine ON/OFF switch in the offposition and the fuel valve in the offposition.
1. Leave the EDCO 2PH and auger connected, then dig a shallow hole or place the unit in a pre-
existing dug hole that will support the EDCO 2PH and auger in a vertical position.
2. Leave the EDCO 2PH and auger connected (no extension), tilt the machine and rest on the
two handle bars opposite of the spark plug (spark plug facing up).
3. Disconnect the EDCO 2PH from the auger and/or auger extension. Set the EDCO 2PH on to a
level/horizontal surface

Transporting:
When transporting an EDCO 2PH the gasoline breather vent must be completely closed to elimi-
nate potential fuel seepage and fire hazards.
Always transport the machine to the job site without the auger attached.
Failure to transport the machine in a vertical manner, disconnected from the auger, can cause
gearcase oil to become trapped in the centrifugal clutch causing excessive slippage in the clutch
assembly diminishing the service life of the clutch assembly.
