SAFETY PRECAUTIONS

WARNING

As with all machinery, there are certain hazards involved with their operation

and use. Exercising respect and caution will considerably lessen the risk of

personal injury. However, if normal safety precautions are overlooked, or

ignored, personal injury to the operator, or damage to property may result.

✗ NEVER allow children, or those physically incapable, of handling this machine,

as it may vibrate considerably, and its handling will requires a degree of
physical exertion.

✗ NEVER use this machine for boring in landfill or soil known to contain rocks or

debris.

✗ NEVER operate this machine whilst under the influence of alcohol or drugs, or

anymedication.

✗ NEVER start the engine in confined spaces.

✗ NEVER make any adjustment or perform a service operation with the engine

running.

✗ NEVER operate an engine driven unit in an explosive atmosphere, near

combustible materials, or where there is insufficient ventilation.

✗ NEVER refuel the engine whilst it is running, and allow the engine to cool

sufficiently before refuelling. Use ONLY recommended 2-stroke mixture. (See
‘Specifications’, p11)

✔ ALWAYS observe all safety precautions for the handling of fuel.

✔ ALWAYS use replacement parts supplied by the manufacturer. The use of non

standard parts could be hazardous.

OVERVIEW

The Earth Borer comprises two major components.....the drive mechanism, or

engine and gearbox, and an Auger. Three sizes of Auger are available from Clarke
International, as follows:

Model EDA100 which has a length of 800mm and a diameter of 100mm

“ EDA150 “ 800mm “ 150mm

“ EDA200 “ 800mm “ 200mm

Additionally an Extension Piece is available, with a length of 400mm

See Accessories on page 10, or your Clarke dealer for details.

The machine is designed for one man operation, but some exertion may be
necessary, due to the forces involved, the quality or type of soil being worked and
the uncertainty of what lies below the surface.

Extreme care must therefore be exercised when using the machine, as it may
lurch suddenly if, for example it comes into contact with strong tree roots or grabs
on dense clay etc. All of these possibilities should be taken into account.

ASSEMBLY

Remove the components from the packing, and inspect for signs of damage
which may have occurred during transit. Should any damage be apparent, please
inform your Clarke dealer immediately.

One carton contains the Auger attachment, the other contains the following
components:

A. The Motor assembly complete

B. The Handle complete with the throttle controls

C. A Wallet containing the items shown in fig. 1. These are:

1. 1 x double ended screwdriver
set. (1 x crosshead, 1 x flat)

2. 2 x Hex. wrenches

3. 1 x Double end Hex. socket

4. 3 x Hex. head socket screws
with spring washers

5. 2 x Hex. Screws with nuts and
spring washers.

Fig.1

It is necessary to attach the handle, throttle controls and the Auger attachment,
as follows:

1. Rest the engine assembly on a workbench

Fig.2

or table, with the handle lying alongside,
ensuring it is the right way up.

2. Take the throttle cable and thread it
through the opening in the underside of
the motor housing, as shown in Fig. 2.

3. Locate the Nipple, on the end of the
cable, in the depression in the end of the
swivel block on the throttle lever, arrowed
in Fig.2, then, ensuring the cable is
positioned so that it lies in the curved guide
provided, grasp the outer sheath, using the
knurled ring adjacent to the threaded end,
and pull, against spring pressure, so that
the threaded end of the outer sheath butts
up against the end of the guide.

You will note that the end of the guide is
threaded internally. Proceed to screw the

Fig.3

threaded end of the sheath into the guide
until all tension is removed from the inner
cable. i.e. the throttle is fully closed.

Screw out again until the position is found
where tension is just beginning to be taken.
At this point, screw up the lock nut (A, Fig. 3)
and tighten, but not before sliding the earth
terminal (C, Fig. 3), between the housing and
the nut, as shown in FIG. 3a .

NOTE: Fig.2 shows the throttle components with

Fig.3a

the engine cover removed. It is not necessary
for the cover to be removed to perform the
above operation.

4. Connect the spade connector shown at
‘B’, Fig. 3, ensuring the protective cover is
firmly in place.

5. Attach the handle using the three Hex. socket
head screws and washers provided, noting
that the handle will fit in one position only.

6. Bolt the selected auger on to the output
shaft using the nuts, bolts and spring washers
supplied (see Fig. 4), ensuring the nuts are
tight. ALWAYS make this check before
each use.

OPERATION

Filling with Fuel

These engines run on a 2-stroke mix as follows:

a. 20 Parts Petrol to 1 Part 2-Stroke MINERAL oil.......or

b. 50 Parts Petrol to 1 Part 2-Stroke SYNTHETIC 2-Stroke oil.

Petrol may be either Unleaded or 4 Star.

Mix the fuel in a separate container in a well ventilated area, away from naked
flame. Observe all precautions for handling fuel. NO SMOKING etc.

Unscrew the fuel tank filler cap, and fill the tank to one inch below the filler neck
using a funnel. Wipe away any spillage thoroughly, replace the cap on the fuel
container and move the container a safe distance away.

WARNING!

NEVER refill the fuel tank when the engine is hot....ALWAYS wait until

it has cooled down sufficiently.

Controls

The control handle, shown opposite,
comprises three major components.

1. The Safety Lever

2. The Throttle Lever, and

3. The Stop/Start Switch.

The Stop/Start Switch has three

positions.....STOP.......MID......START.

1. Lay the Borer, with Auger attached, on its side with pull rope facing upwards.

2. Place the Stop/Start Switch in its MID position.

3. Press the Safety Lever down whilst pulling the Throttle Lever UP with the fingers

- fully.

4. Place the STOP/START Switch in its START position, and release the Throttle and
Safety Levers. The Throttle is now set so that the engine will run at a fast idle.

5. Grasp the pull rope and pull sharply. The engine should start within 2 or 3 pulls.

Fig.5

WARNING!

Be aware that when the engine starts, the Auger will rotate. Ensure
that nothing can snag or become caught up in the spinning helix.

NOTE:

1. For Cold Starting, see notes below.

2. Model ED160 is provided with a decompression device for easy starting - see notes below.

7

Once started, allow to run for short period in order for the engine to warm up,
then blip the throttle briefly using the throttle lever. The STOP/START Switch will
automatically revert to its MID position and the engine will idle. The Auger should
stop rotating at Idle speed, allowing the machine to be raised and moved over
the desired boring point.

In order to operate the throttle once more.....it will be necessary to depress the

SAFETY LEVER FIRST. NEVER force the throttle as it will be in a locked state.

Depress the safety lever with the palm of the hand whilst pulling up the throttle

lever with the fingers. Increasing engine speed will cause the auger to rotate....the

faster the speed, the faster the rotation.

To STOP the engine, place the STOP/START Lever in the STOP position.

Cold Starting

In cold conditions, the choke may be

Choke Control

Lever

Fig.6

used to aid starting.

Before attempting to start, move the
Choke Control Lever towards the
CLOSED position as shown in the
illustration opposite. You may set the
lever to fully or partially closed,
depending upon conditions.

Set the controls as previously
described, and pull the Pull Rope
sharply.

Once the engine has started move the Choke Control Lever towards the OPEN
position so that the engine runs as smoothly as possible. Allow to run for a short
period so that the engine warms, gradually moving the Choke to the OPEN position.

Decompressor

Maintenance

Before each Use

Check the security of the Auger. Ensure the securing nuts are tight.

Check for fuel leaks and rectify before use.

Check for any apparent damage and rectify before use or consult your Clarke
dealer.

Every 25 Hours of Use

A. SPARK PLUG

Remove spark plug, clean and set gap
to 0.5mm.

To gain access to the spark plug,
remove the cover, shown in the
illustration opposite by pressing down on
tab ‘A’. The cover may then be pulled
off

B. AIR FILTER

The Air Filter cover is secured by two
plastic locking tabs - one each side and
shown in the illustration opposite. Press
one of these tabs inwards, using a
suitable tool, whilst pulling the cover
upwards.

Remove the sponge filter and wash in
warm soapy water. Rinse thoroughly
and ensure it is thoroughly dry before
replacing.

Clean the cover and the housing, which
is still attached to the carburettor.

Take great care NOT to allow foreign
bodies to enter the carburettor intake.
Moving the choke control lever to the
CLOSED position, to close off the air
intake, will assist in this matter.

Every 50 Hours of USE

The machine should be serviced by a qualified technician. Please contact your
Clarke dealer for advice.

Storage

If you do not expect to use the machine for some time, then the following tasks
should be undertaken before storing.

1. Empty the fuel tank completely, then start the engine and allow to run until it
stops for lack of fuel. Ensure the fuel cap is replaced and is secure.

2. Remove the spark plug (see page 8) and pour into the cylinder chamber
several drops of 2-stroke oil.

3. Crank the engine slowly, using the pull rope, in order to distribute oil around
the cylinder and piston, then replace the spark plug.

4. Carefully clean all parts, ensuring a film of oil covers bare metal parts...Use a
brush to clean the cooling fins. Oil the throttle linkage at the carburettor.

5. Store in a dry environment, in a shed or garage etc., preferably covered.

Fault Finding

In the event that you find difficulty in starting, or there is lack of power, it is likely
that the problem lies with either carburation or ignition. The following checks will
help to diagnose the problem.

1. Check to ensure the fuel tank has sufficient fuel mixed at the correct ratio.

2. Check to ensure there is no water contamination of the fuel. If necessary,
drain the fuel tank and refill.

3. Check fuel line from tank to carburettor...it may be clogged.

4. Check Fuel Cap....Remove cap then replace loosely...if the engine starts, it is

likely that the fuel cap breather is clogged or damaged. Replace if necessary.

5. Air Filter may be clogged.

6. Spark plug may be dirty or gap is excessive....clean and have it tested.

7. Possible ignition fault...check for spark by removing spark plug, and with lead
attached, crank the engine with metal part of the plug held against bare
metal. DO NOT UNDER ANY CIRCUMSTANCES TOUCH THE METAL PART OF THE
PLUG. The spark plug must be known to be in good condition.

8. The ‘STOP’ button wire may be broken or become disconnected, creating a
permanent STOP condition.

Should these checks not solve the problem...consult your Clarke dealer.
