SAFETY RULES
Basic Safety Precautions
• Read this manual carefully until you completely understand and
can follow all safety rules, precautions, and operating instructions
before attempting to use the unit.
• Restrict the use of your earth auger to adult users who understand
and can follow safety rules, precautions, and operating instructions
found in this manual. Minors should never be allowed to use a
earth auger.
• Do not handle or operate a earth auger when you are fatigued,
ill, or upset, or if you have taken alcohol, drugs, or medication.
You must be in good physical condition and mentally alert. Earth
auger work is strenuous. If you have any condition that might be
aggravated by strenuous work, check with your doctor before
operating a earth auger (Fig. 1). Be more cautious before rest
periods and towards the end of your shift.
• Keep children, bystanders, and animals a minimum of 50 feet (15
meters) away from the work area. Do not allow other people or
animals to be near the earth auger when starting or operating the
earth auger (Fig. 2).
• While working with the earth auger, always use safety protective
approved clothing. The use of protective clothing does
not eliminate injury risks, but reduces the injury effects in
case of accident. Consult your trusted supplier to choose
equipment in compliance with legislation. The clothing must be
proper and not an obstacle. Wear adherent anti-cut clothing.
Protective jackets (Fig.3) and dungarees (Fig.3) are ideal.
Do not wear clothes, scarves, ties or bracelets that can stuck in
to twigs. Tie up and protect long hair (example with foulards, cap,
helmets, etc.). Safety shoes or boots having skid-proof sole
and anti-piercing insert (Fig.4). Wear protective helmet (Fig.5)
in places where there can be falling objects. Wear protective
goggles or face screens. Use protections against noises:
for example noise reduction ear guards (Fig.5) or earplugs.
The use of protections for the ear requests much more attention
and caution, because the perception of danger audio signals
(screaming, alarms, etc.) is limited. Wear gloves (Fig.6, page 8).
• Only loan your earth auger to expert users who are completely
familiar with earth auger operation and correct use. Give other
users the manual with operating instructions, which they have to
read before using the earth auger.
• Check the earth auger each day to ensure that each device,
whether for safety or otherwise, is functional.
• Never use a damaged, modified, or improperly repaired or
assembled earth auger. Do not remove, damage or deactivate any
of the safety devices. Always replace bit immediately if it becomes
damaged, broken or is otherwise removed.
• Carefully plan your working operation in advance. Do not start
cutting until you have a clear work area, secure footing.
• All earth auger service, other than the operations shown in the
present manual, have to be performed by competent personnel.
• The earth auger must only be used for making bores in soil. It
is forbidden to cut other types of material. Do not use the earth
auger as a lever to lift, move or break objects, nor lock it on fixed
supports. It is forbidden to apply tools or applications that are not
the ones indicated by the manufacturer onto the earth auger’s
power take-off.

Fueling (Do Not Smoke!) (Fig.20)
This product is powered by a 2-cycle engine and requires pre-
mixing gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-
cycle engine oil in a clean container approved for gasoline (Fig.18).
RECOMMENDED FUEL: THIS ENGINE IS CERTIFIED TO
OPERATE ON UNLEADED GASOLINE INTENDED FOR
AUTOMOTIVE USE WITH AN OCTANE RATING OF 89 ([R+M]/2)
OR HIGHER (Fig.19).
Mix 2-Cycle Engine Oil with gasoline according to the instructions
on the package.
We strongly recommend the use of 2% (1:50) Efco Two Cycle
Engine Oil, which is specifically formulated for all Efco air-cooled
two-stroke engines.
The correct oil / fuel proportions shown in the table below
are suitable when using the Efco Two Cycle Engine Oil or an
equivalent high-quality engine oil (JASO specification FD or ISO
specification L-EGD).
When oil specifications are NOT equivalent or unknown use 4%
(1:25) oil / fuel mixing ratio.
CAUTION: DO NOT USE AUTOMOTIVE OIL OR
2-CYCLE OUTBOARD OIL.
CAUTION: Never use a fuel with an alcohol percentage
higher than 10%; gasohol up to 10% alcohol or E10
fuel are acceptable.
When using an Oxygenated Gasoline a good practice of Fuel
Management is necessary.
Gasoline Oxygenated with alcohol readily takes/up water when it
is present; the water may be condensed out of humid air or be a
contaminant in the fuel system, including tank.
CAUTION:
- Match your fuel purchases to your consumption;
don’t buy more than you will use in one or two
months;
- Store gasoline in a tightly-closed container in a
cool, dry place.
The use of Oxygenated Gasoline may cause the occurrence of
vapor-lock easier.
NOTE: 2-Cycle Engine Oil contains a fuel stabilizer and will stay
fresh up to 30 days. DO NOT mix quantities larger than usable
in a 30 day period. A 2-cycle oil containing a fuel stabilizer is
recommended.

Preparation for Working
Proper Grip on Handles.
1. Wear non-slip gloves for maximum grip and protection.
WARNING: Hold the earth auger firmly with both hands.
Always keep your LEFT HAND on the left handlebar
and your RIGHT HAND on the throttle handle as shown
in Fig.23. Never use a cross-handed grip. Left-handers
should follow these instructions too.
2. Maintain a proper grip (B, Fig.24) on the earth auger whenever
the engine is running. The fingers should encircle the bar and
the thumb is wrapped under the bar.
Working Conditions
Striking something hard in the earth, such as a rock or gravel,
may cause the drilling tool to slow down suddenly or stop. In
such a situation, some or all of the rotational force (reactive force)
is transferred to the powerhead and handle frame of the earth
auger which can cause the auger powerhead and handles to
rotate suddenly in a counterclockwise direction.
WARNING – Work carefully in rock ground or where
other solid objects may be present. Keep throttle
feed pressure to a minimum. If you feel or hear the
drilling tool strike a solid object, release the throttle
trigger immediately and remove the object before
drilling is continued. When drilling in heavy clay soil,
bore about 1/3 way and remove the auger from the
hole. Clean off auger then continue in slow steps
frequently clearing drill.

en
14
OPERATION
WARNING – You should hold your earth auger firmly to
control sudden jolts and reactive forces. Be prepared
to release the throttle completely if the forces become
too great. If reactive forces are not controlled, rotation
of the handles may result in severe jerking and loss of
control and may cause the handle frame to strike you
or throw you to the ground.
WARNING – To reduce the risk of electrocution and
damage to property, always be alert for underground
pipes and cables and for overhead wires. Before drilling,
obtain the necessary plans and permits. Contact your
local utility company or your locator service, such as
“Miss Utility” or “One Call”, for information as to cable
and pipes locations. Where necessary, confirm actual
locations by use of devices such as cable detectors
and/or by carefully dug trenches. Stay clear of overhead
electrical wires when backing the drilling tool out of the
hole. If any portion of the machine strikes a wire, it will
cause electrical shock or death.

engine begins to turn, bring the choke lever (F, Fig.30) back to
the original position «OPEN». Repeat the procedure until the
engine starts. Once the engine is running, press the throttle (D,
Fig.29) to release it from the half-throttle position and let the
engine idle.
• When pulling the starter rope, do not use the full extent of the
rope as this can cause the rope to break. Do not let starter rope
snap back. Hold the handle and let the rope rewind slowly.
• When the engine starts at starting-throttle, engine speed will
be fast enough for the clutch to engage and move the cutting
tool.
WARNING: Do not cut material with the choke/fast
idle lever at the FULL CHOKE position. Do not
operate your earth auger with the starting throttle
lock engaged. Cutting with the starting throttle lock
engaged does not permit the operator proper control
of the earth auger speed.
NOTE - STARTING WARM ENGINE:
Follow above starting instructions, but do not use the OPEN
(Fig.30) Choke position for start up again. To set fast idle for
warm engine starting, pull choke out completely and push
back in to the original CLOSE (Fig.30) Position.
WARNING: Weather conditions and altitude may
affect carburetion. Do not allow bystanders close to
the earth auger while adjusting the carburetor.
WARNING: Never attempt to start the earth auger
when the bit is in a cut or kerf.
Breaking-in the Engine
The engine reaches the maximum power after 5-8 hours of activity.
During this period of breaking-in do not make the machine function
idly at full throttle, to avoid excessive functioning stress.
CAUTION! – During the breaking-in period do not
vary the carburetion to obtain a presumed power
increment; the engine can be damaged.

Difficult Starting (or starting a flooded engine)
The engine may be flooded with too much fuel if it has not started
after 10 pulls. Flooded engines can be cleared of excess fuel
by following the warm engine starting procedure listed below.
Ensure the ON/STOP switch is in the ON position. Starting could
require pulling the starter rope handle many times depending on
how badly the unit is flooded. If engine fails to start refer to the
TROUBLESHOOTING TABLE (page 23).
Engine is Flooded
If you did not move the choke lever to warm start, quickly
enough after the engine began to fire, the combustion chamber
is flooded.
• Set the on/off swich to STOP.
• Engage a suitable tool in the spark plug boot (Fig.32).
• Pry off the spark plug boot.
• Unscrew and dry off the spark plug.
• Open the throttle wide.
• Pull the starter rope several times to clear the combustion
chamber.
• Refit the spark plug and connect the spark plug boot, press it
down firmly.
• Set the on/off swich to I, the starting position.
• Set the choke lever to warm start – even if engine is cold.
• Now start the engine.
Stopping The Engine
Release the throttle trigger (D, Fig.33) and let the engine return
to idle.
To stop the engine, move the on/off switch (B) to the “ STOP ”
position. Do not put the earth auger on the ground when the bit
is still moving.
In the event that the “ STOP ” position of the switch will not
function, pull the choke lever in CLOSE position (refer to Fig.30)
to stop the engine.
Pre-operation checking
WARNING: THE EARTH AUGER SHOULD NEVER
MOVE AT IDLE. Turn the idle speed screw “T”
counterclockwise to reduce the idle RPM and stop
the bit, or contact a Servicing Dealer for adjustment
and discontinue use until the repair is made.
Serious personal injury may result from the bit
moving at idle.

Working Techniques
General Working Instructions
WARNING: Do not work during periods of high wind
or heavy precipitation.
WARNING: Never work, when visibility is poor or in
very high temperatures.
WARNING: Long-term exposure to noise can result
in permanent hearing impairment. So always use
approved hearing protection.
WARNING: Faulty bits can increase the risk of
accidents.
WARNING - If correctly used, the earth auger is
a quick, easy to handle and efficient tool; if used
improperly or without the due precautions it could
become a dangerous tool. THE MACHINE CAN
CAUSE SERIOUS INJURY. For pleasant and safe
work, always strictly comply with the safety rules
that follow and throughout this manual.
• The gear housing gets hot when the machine has been in
use (Fig.34). To avoid burning yourself do not touch the gear
housing.
• Check the working attachment. Never use bits that are dull,
cracked or damaged.
• Check that the machine is in perfect working order. Check that
all nuts and screws are tight.
WARNING: The complete clutch cover and gear
housing must be fitted before the machine is started,
otherwise the clutch may come loose and cause
personal injury.
WARNING: If you encounter a situation where you are
uncertain how to proceed you should ask an expert.
Contact your dealer or your service workshop.
Avoid all usage which you consider to be beyond
your capability.
• When the engine is switched off, keep your hands and
feet away from the cutting attachment until it has stopped
completely.
• Check the working area for foreign objects such as electricity
cables, insects and animals, etc, or other objects that could
damage the bit, such as metal items.

OPERATION
• If any foreign object is hit or if high vibrations occur stop the
machine immediately. Disconnect the HT lead from the spark
plug. Check that the machine is not damaged. Repair any
damage.
• If anything jams in the bits while you are working, switch off the
engine and wait until it has stopped completely before cleaning
the bits. Disconnect the HT lead from the spark plug.
• Always wear heavy-duty gloves when repairing the cutting
attachment. This is extremely sharp and can easily cause cuts.
• Release the throttle trigger as soon as the cut is completed,
allowing the engine to idle. If you run the earth auger at
full throttle without a cutting load, unnecessary wear or
damage can occur to the bit and engine.
Local rugulations
Observe all country-specific and local regulations and ordinances
regarding soil working.
Preparations
Before starting work, scare away small animals so that they
cannot be injured.
Working techniques
WARNING! - Do not use damaged or excessively
worn bits. If the bit gets jammed, turn off engine
before removing the obstruction.
The auger becomes trapped in the drill hole, turn off the engine
immediately and remove as described in the chapter entitled
“Removing a trapped auger”.
WARNING – To reduce the risk of injury, never touch
a rotating drilling tool or drilling spindle with your
hand or any part of your body. It continues to rotate
for a short period after the throttle lever is released.
Always shut off the engine before putting the machine
down or transporting it over a long distance.
When taking the drilling tool out of the hole, lift the
machine vertically so that the tool comes out straight
without canting. Cover and clearly mark boreholes,
to prevent anyone from stepping in a hole.
Working with shaft extension (optional special accessory, Fig.35)
Do not fit the shaft extension until the full length of the auger is in
the hole.
WARNING – Starting hole with the shaft extension
fitted increases the risk of personal injury because
the unit is then at chest height and cannot be kept
properly under control.
For the same reason the shaft extension must be
removed before the auger is pulled out of the hole.
Removing a trapped auger
If the auger jams in the drill hole, shut off the engine immediately.
Move on/off switch in direction of STOP (B, Fig.36).
Transportation
When you walk with your earth auger, turn off the engine. Grip the
front handle and keep the bits behind you.

MAINTENANCE
Carburetor Adjustment
Before adjusting the carburetor, clean the starter cover vents as
shown in Illustration Fig.37, and air filter as shown in Illustration
Fig.38, refer to Operation-Starting Unit and Maintenance-Air
Filter Sections for details. Allow the engine to warm up prior to
carburetor adjustment.
This engine is designed and manufactured in order to comply with
EPA (Environmental Protection Agency) Phase 1 regulations.
The carburetor is factory set and should not require adjusting.
The carburetor will permit only limited adjustment of the “L” (Low
Jet) and “H” (High Jet) needles (Fig. 39). Any adjustment should
be done by a Servicing Dealer.
Under no circumstances should the “L” (Low Jet) and “H” (High
Jet) needles be forced outside the range of adjustment.
WARNING: Serious damage can occur to the engine
if improper adjustments are made to the “L” and “H”
needles. Do not force the “L” and “H” needles outside
the adjustment range in such case the engine will not
run in compliance with emissions regulations.
Idle Speed Adjustment
• If the engine starts, runs, and accelerates but will not idle; turn
the idle speed screw “T” clockwise to increase idle speed
(Fig.39).
• If the earth auger turns at idle, turn the idle speed screw
“T” counterclockwise to reduce the idle RPM and stop the
bit movement. If the bit still moves at idle speed, contact a
Servicing Dealer for adjustment and discontinue use until the
repair is made.
WARNING: Don’t tamper with the carburetor.
WARNING: With the engine idling (2600 rpm), the
bit should not move. We recommend that you have
the dealer or an authorised mechanic carry out any
carburetor adjustments.
WARNING: Weather conditions and altitude may
affect carburation.
WARNING: Do not allow anyone to stay close to the
earth auger while working or while adjusting the
carburetor.
Fuel Filter
Check the fuel filter (B, Fig.40) periodically. Replace it if
contaminated or damaged.
