DANGER
?
Avoid Work Site Hazards Avoid contact with
gas lines, buried cables and water lines. Call
utility line location services to identify all
underground utilities before you dig. Prepare
work site properly. Avoid operating near
structures or objects that could fall onto the
machine. Clear away debris that could move
unexpectedly if run over. Avoid boom or arm
contact with overhead obstacles or overhead
electrical lines. Never move any part of
machine or load closer than 3 m (10 ft) plus
twice the line insulator length to overhead
wires.
Keep bystanders clear at all times. Keep bystanders away from raised booms, attachments,
and unsupported loads. Avoid swinging or raising booms, attachments, or loads over or near
personnel. Use barricades or a signal person to keep vehicles and pedestrians away. Use a
signal person if moving machine in congested areas or where visibility is restricted. Always
keep signal person in view. Coordinate hand signals before starting machine. Operate only
on solid footing with strength sufficient to support machine. When working close to an
excavation, position travel motors away from the hole. Reduce machine speed when operating
tool on or near ground when obstacles may be hidden (e.g., during snow removal or clearing
mud, dirt, etc.).

Avoid Machine Tip Over
- Do not jump if the machine tips. You will be
unlikely to jump clear and the machine may
crush you.
- Load and unload from trucks or trailers carefully. Be sure truck is wide enough and on a firm level
surface. Use loading ramps and attach them properly to truck bed. Avoid trucks with steel beds
because tracks slip more easily on steel.
- Be careful on slopes. Use extra care on soft, rocky or frozen ground. Machine may slip sideways in
these conditions. When traveling up or down slopes, keep the bucket on uphill side and just above
ground level.
- Be careful with heavy loads. Using oversize buckets or lifting heavy objects reduces machine
stability. Extending a heavy load or swinging it over side of undercarriage may cause machine to
tip.
- Ensure solid footing. Use extra care when operating near banks or excavations that may cave-in
and cause machine to tip or fall.

SAFE OPERATION
The best insurance against accidents is to
abide by the safety regulations.
Read and understand this section carefully,
before operating the excavator.
Every user, however experienced, should
carefully read and understand this section
and those of the attachments and accessories
before taking the excavator into operation.
The owner is obliged to inform the operators
of these instructions in detail.
Keep this manual in the toolbox.
1. BEFORE OPERATION
1. Make yourself acquainted with the excavator
and be aware of its limits. Read this operator's
manual carefully before starting the excavator.
2. Obey the danger, warning and caution labels
on the machine.
3. Track width 690mm. Operate in the correct
track.
4. Do not use the excavator under the influence
of alcohol, medication or other substances.
Fatigue is also dangerous.
5. Check the surroundings carefully before using
the excavator or when attachments are being
attached.
The excavator is not intended to be used in
a contaminated environment.
Neither the excavator as a whole nor its
internal components are intended for use in
potential explosive atmospheres.
Pay attention to the overhead clearance with
electric wires.
Check for pipes and buried cables.
Check for hidden holes, hindrances, soft
ground and overhangs.
During excavator use do not allow any
persons within the working range.
6. Do not allow other persons to use the
machine before having informed him on the
exact operation and work instructions, and be
assured that the operator's manual has been
read and understood.
7. Do not wear baggy, torn or too large clothing
when working with the excavator. Clothing
can get caught in rotating parts or control
elements which can cause accidents or
injuries. Wear adequate safety clothing, e.g.
safety helmet, safety shoes, eye protection, ear
protection, working gloves, etc., as necessary
and as prescribed by laws or statutes.
8. Do not allow passengers to get on any part of
the excavator seat during operation.
9. Check mechanical parts for correct
adjustments and wear. Exchange worn or
damaged parts immediately. Check nuts and
bolts regularly for tight fitment. (for details
see "Care and Maintenance").
10. Keep your excavator clean. Heavy soiling,
grease, dust and grass can inflame and cause
accidents or injuries.
11. Use only authorized attachments.
12. Before starting the excavator, be absolutely
sure that the excavator has been filled with
11
Front Rear
fuel, lubricated, greased and undergone other
maintenance work.
13. Do not modify the excavator, otherwise it
could lead to unforeseen safety problems.
2. STARTING OF THE EXCAVATOR
1. Get into and out of the machine safely. Always
face the machine. Always use handrails
and available steps and keep yourself well
balanced. Do not hold any of the control
Ievers and switches. Do not jump on or off the
machine, whether stationary or in motion.
2. Start and control the excavator only from the
operator's seat. The driver should not lean out
of his seat when the engine is running.
3. Before starting the engine, make sure that all
control levers are in their neutral positions.
4. Do not start the engine by jumping the starter
connections. Do not try to circumvent using
the starter switch, otherwise the engine could
start suddenly and the excavator could move.
5. Make sure that the dozer is on the front side.
(The dozer must be raised.) If the swing frame
has been turned 180 , i.e. the dozer is, seen
from the operator, "behind", then the travel
direction is opposite to the drive direction
of the levers (when activating the drive
lever forwards, the excavator, seen from the
operator, will move backwards).
6. Do not run the engine in closed or badly
ventilated rooms. Carbon monoxide is
colourless, odourless and deadly.
7. Keep all safety equipment and covers in place.
Replace damaged or missing safety devices.
8. Precautions against tipping over. In order to
secure safe operation, keep away from steep
slopes and embankments. Do not swing the
bucket downwards. Lower the dozer during
digging. Keep the bucket as low as possible
while driving upwards. Turn slowly on slopes.
Do not keep the excavator near the edges of
trenches and banks, as the earth can give way
due to the weight of the excavator.
9. Watch out at all times where the excavator
is being moved to. Keep an eye out for
hindrances.
10. Keep enough distance from trench and bank
edges.
Safety for children
Tragedy can occur if the operator is not alert
to the presence of children. Children generally
are attached to machines and the work they
do.
11. Never assume that children will remain where
you last saw them.
12. Keep children out of the work area and under
the watchful eye of another responsible adult.
13. Be alert and shut your machine down if
children enter the work area.
14. Never carry children on your machine. There
is no safe place for them to ride. They may
fall off and be run over or interfere with your
control of the machine.
15. Never allow children to operate the machine
even under adult supervision.
16. Never allow children to play on the machine
or on the implement.
17. Use extra caution when backing up, look
behind and down-make sure area is clear
before moving.
18. When parking your machine if at all possible
park on a firm, flat and level surface. Lower
the implements to the ground, remove the
key from the ignition and chock the crawlers.
3. AFTER OPERATION
Before leaving the machine,
Bring the excavator to hard even ground.
Lower the attachments and the dozer blade
on the ground.
Stop the engine.
Lock all control levers.
Remove the key.

4. SAFE LOADING AND TRANSPORT OF THE
EXCAVATOR
1. Observe all regulations concerning the
transport of excavators on public roads.
2. Use adequately long and robust ramps
when loading on a truck. (for details see
"TRANSPORTING THE EXCAVATOR ON A
TRUCK"); You can also lift the machine onto
the truck. (for details see "LIFTING OF THE
EXCAVATOR").
3. Do not change the running direction and to
avoid a tipping over, do not try to swing the
attachment crosswise to the loading ramps.
4. After loading of the excavator on a truck,
swivel the upper body around to the back of
the truck and engage the swing lock pin.
Lower the attachment on the loading plane,
release the pressure from the hydraulic
system and lock the boom with the lever.
Block the crawlers with blocks and wire down
the excavator. After loading the excavator
on a truck, tie down the undercarriage of the
excavator with a strong steel wire on the truck.
5. Do not brake abruptly with the excavator
loaded. Fatal accidents could happen.
5.
MAINTENANCE
Before doing maintenance work on the excavator,
place the machine on even solid ground, Iower
the attachments on the ground, stop the engine
and release the cylinder pressure by actuating
the levers. When dismantling hydraulic parts,
make sure that the hydraulic oil has cooled down
sufficiently to avoid burns.
Start maintenance work carefully, e.g. loosen
screws slowly so that oil will not squirt out.
1. Before doing work on the engine, the exhaust
system, the heat protection shield and the
hydraulics, let the excavator cool down
sufficiently.
2. Turn off the engine at all times when filling
with fuel. Avoid spilling and over-filling of
fuel.
Lock lever

Unlock
13
3. Smoking is prohibited while fuelling and
handling the battery! Keep sparks and
fire away from the fuel tank and battery.
Flammable gases escape from the battery.
4. When the battery is dead, it can be started by
pull the recoil starter.
5. To avoid short-circuiting the battery, always
remove the earth cable first and attach the
plus cable first.
6. Keep a first-aid box and a fire extinguisher at
hand at all times.
7. Leaking hydraulic fluid has enough pressure to
penetrate the skin and cause serious injuries.
Leakages from pin holes can be totally invisible.
Do not use the bare hand for checking on
possible leakages. Always use a piece of wood
or cardboard. It is strongly recommended you
use a face mask or eye protection.
Should injuries occur with leaking hydraulic
fluid, contact a doctor immediately. This
fluid can cause gangrene or serious allergic
reactions.
8. To avoid leakage of battery acid which
contains heavy metals, do not throw the
battery away.
9. Observe all laws and regulations concerning
the disposal of used oil, coolants, solvents,
hydraulic fluids, battery acids and batteries.
10. To avoid fire, do not heat the hydraulic
components (tanks, pipes, hoses, cylinders)
before they have been drained and washed.
11. Use a face mask or eye protection to protect
the eyes and respiratory system against
dust and other foreign particles.
12. Do not crawl under the excavator if the
excavator is only supported by the boom
and arm or the dozer. The excavator can
tip over or lower itself due to hydraulic
pressure loss. Always use safety struts or
other appropriate supports.
13. Use no parts which are lined with asbestos.
Do not use these kind of parts even if they
can be installed.
14. Fire prevention
Excavator and some attachments have
components that are at high temperatures
under normal operating conditions. The
primary source of high temperatures is the
engine and exhaust system. The electrical
system, if damaged or incorrectly maintained,
can be a source of arcing or sparks.
The following fire prevention guidelines
will help to keep your equipment up and
running efficiently and keep the risk of fire
to a minimum.
Blow off all accumulated debris near hot
engine exhaust components such as cylinder
head of gasoline engine and exhaust manifold
as well as exhaust pipes and muffler more
frequently when working in severe conditions.
Clean out all accumulated flammable
debris such as leaves, straw, pine needles,
branches, bark, small wood chips and any
other combustible materials from inside the
machine belly pans or lower unit structures as
well as from area in proximity to the engine.
Inspect all fuel lines and hydraulic hoses
for wear or for deterioration. Replace them
immediately if they begin to leak.
Examine electrical wiring and connectors
frequently for damage. Repair any wires
that are loose or frayed before operating the
machine. Clean all electrical connections and
tighten all electrical connections as necessary.
Inspect the exhaust system daily for any
signs of leakage. Check for broken pipes
and muffler and also for loose or missing
bolts, nuts and clamps. If any exhaust leaks
or fractured parts are found, repairs must
be completed prior to operation.
Always keep a multipurpose fire extinguisher
on or near the machine. Be familiar with the
operation of the fire extinguisher.

Checkpoints after Starting the Engine
After starting the engine, but before starting
operation, check following points:
1. Put the throttle lever in the "LOW" position
and let the engine idle for approx. 5 minutes.
This allows the engine lubricant to warm up
and penetrate every part of the engine.
2. Once the engine has warmed up, check:
the alarm lamp "Battery charge" goes out
when accelerating the engine.
the colour of the exhaust gas is normal and no
abnormal noises or vibrations are heard or felt.
no fluid is leaking from pipes or hoses.
Should any following conditions arise, stop the

EXCAVATOR OPERATION
CONTROL OBSERVATIONS
DURING OPERATION
RUNNING-IN OF THE NEW
EXCAVATOR
Stop the Engine immediately if:
After starting the engine, but before starting
operation, check following points:
Sudden increase or decrease in engine
revolution occurs.
Sudden abnormal noises occur.
Exhaust gases turn suddenly very dark.
Make following control observations during
operation to be sure that everything functions
normally.
The operation and care of the new excavator
influences its life span. Your new excavator
has been carefully checked and tested before
leaving the factory. In spite of this, all movable
components must run-in during the first 50 work
hours. Do not work with full revolution and full
loads during this period. It is most important
to run-in your excavator properly in order to
achieve its full performance and longevity. During
the running-in, the following points should be
adhered to in all cases.
Do not Work with Full Revolutions or Full Loads
during the First 50 Working Hours.
Let the engine warm up sufficiently in the cold
season.
Do not let the engine rev-up more than
necessary.
Oil Change in the Run-in Stage.
The lubrication oil plays a specially important role
during the run-in phase of the excavator. The
numerous movable parts are not yet run-in, so
that many fine metal particles can develop and
cause damage or shorten the lifetime of many
components. Pay attention to the oilchange
intervals and execute them sooner rather than
later as necessary. See the subject "Care and
Maintenance" for more details on the oil-change
intervals.
When the engine
stops suddenly, push forward the right
handrail to let the bucket fall down, so
as not to cause misoperation, resulting in
injury due to the bucket fall.

NOTE
OPERATION OF THE BOOM
To raise the boom, pull the attachment control
lever back.
The boom is equipped with a cushion cylinder
which prevents excavated material in the bucket
from fall-in out. By low hydraulic oil temperature,
(e.g. right after starting the engine) the cushioning
function will only be effected after a certain delay
(approx. 3 to 5 seconds). This condition results
from the viscosity of the hydraulic oil and is no
sign of a malfunction.
When lowering the
boom, make sure that it does not hit the
dozer and that the bucket teeth do not
touch the dozer.

OPERATION OF THE ARM
Pull back the left attachment control lever and
the arm will be pulled in. To move the arm out,
push the control lever towards the front.
When pulling in the
arm, the movement may stop for a short
moment when the arm is in its vertical
position. This is caused by the fact that at
this position the maximum load for the arm
and bucket is reached, and the hydraulic
pressure in the cylinder is not high enough.
This is a characteristic of the hydraulic
system and is not a sign of a malfunction.

side sweeps of the bucket to move earth
piles.
Under all circumstances avoid the following
operations:
Excavation using the gravitational
impact of the machine.
Compacting of gravel or soil using the
dropping action of the bucket.
Excavation using the travelling power
of the machine.
Do not try to drop or shake of soil adhering
to the bucket in the manner shown in the
explanation below. This can cause damage
to the machine.
Adhering soil can be shaken off when the
bucket is being emptied by moving the
bucket out to the maximum stroke of the
cylinder. Should this not suffice, swing out
the arm as far as possible and operate the
bucket back and forth.
Do not hit the dozer with the boom
cylinder! Make sure that the boom cylinder
does not hit the dozer when carrying out
deep excavation. If necessary swivel the
upper structure so that the dozer is at the
back of the machine.
Pay attention when pulling in the bucket!
When pulling in the bucket (for driving or
transportation) avoid hitting the dozer.
