INTRODUCTION

Power auger Ground Drill-16 HERCULES is used for work with two opera­tors. During operation seizure of the auger may occur and the equip ment
may rotate in reverse - that’s why both operators must be very careful
during operation and know and follow all precautions and possible risks.
Return stroke is partly reduced by the power auger structure. You should
know how to use the instrument to avoid damages.
Options can be changed by the manufacturer without notice.

PRECAUTIONS

Wear a long-sleeved shirt and long pants closed at the cu.

Do not wear neck-tie or other loosely danging garments. Such articles may
become entangled in the drill when working.
Wear protective goggles.
Wear helmet when working.
Wear work shoes equipped with no-slip tread.
Wear ear plugs to protect the ear drum from noise.
Do not work for long periods of time in summer and winter. Take breaks
frequently.
Do not use the auger in the rain. The possibility of your slipping is in­creased when the ground is wet.
Do not use the auger indoors or in poorly ventilated places.
Do not smoke in the vicinity of the auger. This equipment runs on gasoline.

Keep the equipment from ames and sparks.

Do not remove the gas cap or refuel while the engine is running or hot.
Wipe the auger body of any spilled gasoline after refueling.
Store fuel in approved containers and keep in a cool place.

CHECK BEFORE START-UP

Check all bolts and nuts are securely tight. Tighten where necessary.
Check the cutting blades to avoid chipping, cracking or bending. NEVER use
a drill when the blade or the ground drill is damaged.

CAUTIONS DURING USAGE

Do not allow other persons within 5 meters of the worksite. IT IS DANGER­OUS for pets and children to be near the equipment when operating.
Be careful when drilling through rocky ground. This equipment may rotate
in reverse and damage.
Work only in a stable position.

Be sure to stop the engine before allowing persons to approach within 5

11

m of the equipment.
Do not allow children or anyone who is unskilled in equipment usage to
operate the equipment.
Never touch the drill bit when the engine is running. Be sure the engine is

o and the drill has stopped rotating before handling.

Beware of the rotating drill bit.
Be sure the drill bit has stopped moving before placing on the ground.
When deep drilling, do not attempt to complete work in one stretch. Ex­tract soil in 2 or 3 steps.
Before servicing the auger or making repairs, always stop the engine, re­move the plug cap from the spark plug and allow the engine to cool down.
Before storing the auger drain all remaining fuel and wipe the equipment
clean of dirt and debris.

NEVER store the auger near live ames.

PREPARATION BEFORE OPERATION

Handles must be placed on the frame in the following way: loosen the screw
and turn the handle by 90 degrees to place it in the horizontal position.
Tighten the screw.

CONNECTION OF THE AUGER TO THE REDUCTION GEAR

Combine drive shaft and shank end. Insert the shaft into the shank end. Fix
the connection with the help of pin. Use the adapter if you want to set the
auger bit with another type or diameter of the attachement.

AUGER CHECKUP

1. Check availability of all parts. This goes especially for the spark plug.

2. Check the air intake and outlet for clogging.

3. The auger uses an air-cooled engine. If the air passage is blocked, the
engine may overheat.

4. Check the air lter for dirt. A dirty air cleaner will cause the auger to burn

excess fuel.

THE LEVEL OF OIL IN THE ENGINE

Caution: Oil is a major factor aecting performance and service life. Use
detergent oil. It’s not recommended to use vegetable-based uid. Check

the engine oil level with the engine stopped and in a level position.

Note: SAE 10W-30 is recommended for general use. Use oil SAE Synthetic
5W-30 when the average temperature in your area is within the recom­mended range.
Check the engine with the engine stopped and in a level position.

1.Remove the oil ller cap/dipstick and wipe it clean.

2. Insert the oil ller cap/dipstick into the oil ller neck as shown, but do

not screw it in, then remove it to check the oil level.

3. Add the oil. If the oil level is near or below the lower limit mark on the
dipstick.

NOTE: SHIP AND STORE THE GROUND DRILL ONLY IN THE UPPER PO­SITION OF THE STARTER. OTHERWISE THE OIL FROM THE CRANK CASE
CAN GET INTO THE AIR FILTER, CARBURETOR AND CYLINDER. THE
TRANSPORTATION IN THE PACKAGE WITH OPERATING FLUIDS (OIL,
PETROL) IS FORBIDDEN!

FUEL

1. Remove the fuel tank cap and check fuel lever. If necessary add some
fuel.

2. Use only motor gasoline (with a minimum of 92 octane or unleaded or

low leaded gasoline).

Never use mixture of oil-fuel or sour gasoline. Avoid getting dirt or water
in the fuel tank.

STARTING ENGINE

1. Close the air shutter. Turn the choke valve switch to the START position.
Attention: If the engine is very hot or the temperature is high, do not close
the choke valve.

2. Start the engine: turn the engine switch to the I position, slowly pull the
handle until there is sensation of resistance, and then pull quickly and
strongly.
Attention: Don’t loosen the handle suddenly in order to avoid rebounding
and hitting the engine. You should replace it along the direction of resil­ience force of starting. Place the air shutter into the WORK position after
the engine warm-up.

OPERATION

Caution: Ground drill is designed for the operation with 1 (density

600...1600 kg/m3) and 2 ( density 1600... 1900 kg/m3) classes of soil. Con­tinuous working time of the ground drill with 1 class of soil (sand, clay sand,

vegetable soil, peat) doesn’t exceed 5 min. Continuous working time of the
ground drill with 2 class of soil (light loam, sand with crushed stone) is no

more than 3 min. Recommended interval between continuous usage is no
less than 15 min with full stoppage of the engine. It’s forbidden to decline
the ground drill from the axis of drilling more than 3°. Excessive deviation
can lead to the breakage of the gear case parts.
Never try to drill the hole on full depth of the auger bit. Drill step-by-step.

Excessive pressure on the ground drill can lead to the breakage of the gear
case, overheating of the engine and its breakdown. Deep the auger drill
on 20-30 cm and raise it slightly in the hole. Remove earth from the auger
bit. Don’t take out the whole rotating auger bit from the hole. It can lead to
the injury. Don’t speed up if the auger bit is jammed in the ground. It can
lead to the breakage of the gear-wheel of the gear case and the parts of
the engine. Slow down the engine and disconnect it from the auger bit. Set
the pivot of appropriate diameter into the hole of pin – release the auger
bit turning it back.

1. Let engine warm for at least 1 min.

2. Press or release throttle lever to get desired rpms. If the engine reduce
rpms on load, adjust the position of throttle lever.

Important! Do not work without workmate. Otherwise it can lead to the
damages. Avoid running at high rpms for long periods. The unit needs time
for lubricant to get to all internal parts. Do not run the motor at high rpms
without load.

STOPPING

1. Release throttle to idle speed.

2. Move main switch on/o to 0.

Note: When storing for long periods, remove all fuel from the gas tank. Do
not leave the gas tank at an angle. The pressure inside the tank can cause
the gas to spill out. The gas can spill out on the hot parts of the engine. it

can lead to the ame development.

MAINTENANCE

Make sure the engine is o before you begin any maintenance or repairs.

To prevent accidental engine start disconnect spark plug cap.

Note: Check and adjust regularly the engine if you want to achieve high
performance of it. Regularly maintenance extends engine life. In the table
below there is a maintenance schedule with regular service periods.

Note:

(1) Clean more often under dusty conditions or when airborne debris is

present.

(2) Change engine oil every 25 hours when used under heavy load or in

high ambient temperatures.

CHANGE ENGINE OIL

1. Drain the used oil while the engine is warm.

2. Remove the ller cap/dipstick, the drain bolt and sealing washer. Drain

oil.

3. Reinstall the drain bolt and sealing washer, and tighten it securely.

4. With the engine in a level position, ll to the upper limit mark on the

dipstick with the recommended oil. Check the oil level.

5. Reinstall the oil ller cap/dipstick securely.

MAINTENANCE OF AIR FILTER

A dirty air lter will restrict air ow to the carburetor, reducing engine per­formance. If you operate the engine in very dusty areas, change the air

lter more often than specied in the maintenance schedule.
a) Remove the air lter cap. Detach the element;
b) Check the condition of the paper ltering element. Damaged or durty

element must be changed.

c) Put the detail on its place.
Caution: Never use gasoline or other dissolvents to clean air lter. Ignition
could result. Operating the engine without an air lter, or with a damaged
air lter, will allow dirt to enter the engine, causing rapid engine wear.
