■SAFETY RULES
1、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. Be more cautious before rest periods and towards the end
of your shift.

(15meters) 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.
• While working with the earth auger, always use safety protective

6
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 and dungarees are ideal. Do not wear
clothes, scarves, ties or bracelets that can stuck into 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. Wear protective helmet in
places where there can be falling objects. Wear protective goggles or face screens. Use protections against noises:for
example noise reduction ear guards 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.
• 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

7
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.
• It is unadvisable to hitch tools or applications to the P.t.o. that are not specified by the manufacturer.
2、Fuel Handling
WARNING: Gasoline is an extremely flammable fuel.Use extreme
caution when handling gasoline or fuel mix. Do not smoke or bring
any fire or flame near the fuel or the earth auger.
• To reduce the risk of fire and burn injury, handle fuel with care.
It is highly flammable.
• Mix and store fuel in a container approved for gasoline.
• Mix fuel outdoors where there are no sparks or flames.
• Select bare ground,stop engine,and allow to cool before refueling.
• Loosen fuel cap slowly to release pressure and to keep fuel from escaping around the cap.

8
• Tighten fuel cap securely after refueling. Unit vibration can cause an improperly tightened fuel cap to loosen or come
off and spill quantities of fuel.
• Wipe spilled fuel from the unit. Move 10 feet (3 m) away from refueling
site before starting engine.
• Never attempt to burn off spilled fuel under any circumstances.
• Do not smoke while handling fuel or while operating the earth auger.
• Store fuel in a cool, dry, well ventilated place.
• Never place the earth auger in a combustible area such as dry leaves, straw, paper, etc.
• Store the unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.
• Never take the cap off the tank when the engine is running.
• Never use fuel for cleaning operations.

3、Operation and Safety
WARNING: Always hold the earth auger with both hands when the
engine is running. Use a firm grip with thumbs and fingers
encircling the earth auger handles.
• Keep all parts of your body away from the earth auger when the engine
is running.
• Always carry the earth auger with the engine stopped the bit to the rear, and the muffler away from your body. When
transporting in a vehicle, properly secure your earth auger to prevent turnover, fuel spillage and damage to the earth
auger.
•Do not operate a earth auger with one hand! Serious injury to the operator helpers, bystanders, or any combination of
these persons may result from one-handed operation. An earth auger is intended for two-handed use.
• Before you start the engine, make sure the earth auger is not contacting any object.
• Shut off the engine before setting down the earth auger.Do not leave the engine running unattended.
• Only use the earth auger in well-ventilated places, do not operate the earth
auger in explosive or flammable atmospheres or in closed environments,
Beware of carbon monoxide poisoning.
• Do not operate earth auger from a ladder. Always cut from a firm-footed
and safe position.

10
• Do not work near electric cables.
WARNING – Contact with electrical cables or wires can cause serious
injury or death as a result of electrical shock. This unit is not insulated.
• Keep the handles dry, clean, and free of oil
or fuel mixture.
• When the earth auger is running, grip the left handle firmly with your left
hand and the right handle with your right hand.
• Never raise the earth auger above shoulder height.
WARNING – Striking a hard object in the earth with the turning auger and the resulting slowing or stopping of
