SAFETY
USE AND CARE OF THE MACHINE
SAFE HANDLING OF PETROL
• Petrol is very flammable and its gases can explode if they ignite.
• Take safety measures when handling petrol to reduce the risk of serious injury.
• Use a suitable petrol can when filling or draining the tank.
• Carry out this work in clean, well-ventilated outdoor areas.
• Do not smoke. Do not allow sparks, naked flames or other sources of fire to get near when filling up with petrol or work-
ing with the machine.
• Never fill the tank indoors. Keep earthed, electrically conductive objects, such as tools, away from exposed electrical
parts and wires to avoid sparking or arcing. This could ignite petrol gases.
• Always switch off the engine and let it cool down before refilling the fuel tank. Never remove the fuel filler cap or fill
fuel into the tank while the engine is running or while the engine is hot.
• Do not use the machine if you know there is a leak in the fuel system. Slowly loosen the fuel filler cap to release any
pressure in the tank. Never overfill the tank (petrol should never be above the marked maximum fill level). Close the
fuel tank securely again with the fuel filler cap and wipe up any spilled petrol.
• Do not use the machine if the fuel filler cap is not screwed tightly shut. Avoid ignition sources near spilled petrol. If
petrol has been spilled, do not attempt to start the machine. Move the machine away from the area of the spillage and
prevent the formation of ignition sources until the petrol gases have dissipated.
• Store petrol only in containers specially manufactured for this purpose.
• Store petrol in a cool, well-ventilated area away from sparks and naked flames or other sources of ignition. Never store
petrol or the machine with a filled tank in a building where petrol gases could reach sparks, naked flames or other
ignition sources such as water heaters, ovens, clothes dryers or similar.
• Allow the engine to cool before storing the machine in an enclosed area.
• Never pick up or carry the machine while the engine is running.
• Do not handle the machine violently.
• Use the right machine for your area of application. The right machine will do the job it was designed for better and more
safely.
• Do not change the speed governor setting of the engine or over-rev it. The speed control system controls the maximum
speed of the engine with maximum safety.
• Do not hold your hands or feet near rotating parts.
• Avoid contact with hot petrol, oil, exhaust gases and hot surfaces. Do not touch the engine or exhaust silencer. These
parts become particularly hot during use. They are still hot a short time after the machine is switched off.
• Allow the engine to cool down before carrying out maintenance or adjustment work.
• If the machine starts to make unusual noises or vibrations, switch the engine off immediately, disconnect the spark
plug cable and determine the cause. Unusual noises or vibrations are usually a safety sign of faults.
• Only use assembly and accessory parts approved by the manufacturer. Failure to do so may result in injury.
• Service the machine. Check for misalignment or jamming of moving parts, damaged parts and other conditions that
could impair function of the machine. Have the machine repaired before any further use if you find any damage. Many
accidents are the result of poorly maintained equipment.
• Keep the engine and silencer free of grass, leaves, excess grease or soot encrustation to reduce the risk of fire.
• Never pour or splash water or any other liquid onto the machine.
• Keep the handles dry, clean and free of small parts.
• Clean the machine after every use.
• Follow the applicable waste disposal guidelines for petrol, oil etc. to protect the environment.

SAFETY
COMMISSIONING
Always make sure the product is fully assembled before commissioning!
ATTENTION
1. Get on and off the machine in a safe manner. Always look in the direction of the machine. Always use the handrails and
existing steps and keep your balance. Do not hold on to the control levers and switches. Do not jump from the stationary
or moving machine.
2. Only start and control the excavator from the operator's seat. The driver must not lean out of their seat when the
engine is running.
3. Before starting the machine, make sure that all operating levers are in the neutral position.
4. Do not start the engine by bridging the connections of the starter motor. Do not attempt to bypass the ignition lock,
otherwise the engine could start suddenly and the excavator could start moving.
5. Ensure that the bulldozer blade is at the front. (The bulldozer blade must be raised.) If the swivel frame has been rotat-
ed by 180°, i.e. the bulldozer blade is at the rear from the operator's point of view, the direction of travel is opposite to
the direction of travel of the levers. (If the drive lever is moved forwards, the excavator moves backwards as seen by the
operator.)
6. Do not run the engine in closed or poorly ventilated spaces. Carbon monoxide is colorless, odorless and deadly.
7. Leave all safety elements and cladding in place. Replace damaged or missing safety devices.
8. Precautionary measures against overturning. Keep away from steep slopes and embankments to ensure safe opera-
tion. Do not swivel the bucket downwards. Lower the bulldozer blade when digging. Keep the bucket as low as possible
when travelling uphill. Turn carefully on slopes. Do not keep the excavator close to the edges of trenches and embank-
ments, as the earth could give way due to the weight of the excavator.
9. Always pay attention to where the excavator is moving. Keep an eye out for obstacles.
10. Keep sufficient distance from ditches and bank edges. Protection of children! If the operator does not pay attention
to the presence of children, tragic accidents can occur. Children are generally attracted to machines and their activities.

instructions.
ATTENTION
Check the following points after starting the engine, but before starting work:
1. Move the throttle lever to the "LOW" position and allow the engine to idle for approx. 5 minutes. This warms up the
engine oil and allows it to penetrate all parts of the engine.
Note: This operation in idle mode is usually called "warming up".
2. After the engine has warmed up, check as follows:
• The color of the exhaust gases is normal and no abnormal noises or vibrations can be heard.
• No liquid escapes from the pipes or hoses.
Stop the engine immediately if any of the following circumstances occur:
• The speed of the engine suddenly increases or decreases.
• Sudden abnormal noises.
• The exhaust fumes are black.

SAFETY
STARTING THE ENGINE WHEN COLD
SWITCHING OFF THE ENGINE
Ensure that the safety lever is locked during warm-up.
ATTENTION
1. Pull the throttle lever out by 1/3.
2. Pull the air regulator handle back down and the start key to "ON" for five seconds to start. When the petrol engine
starts, the left-hand air regulator handle resets. (Note that the petrol engine can be started when the vehicle is warm
without pulling the air regulator handle).
3. Release the key when the engine has started. It automatically returns to the "ON” position.
Allow the engine to idle for about 5 minutes to cool down.
1. Move the throttle lever to the idle position.
2. Carefully lower the attachments to the ground using the levers.
3. To stop the engine, turn the key to the "OFF" position and remove the key.
Note: After starting the engine, allow it to warm up for about 10 minutes without load. If the temperature of the
hydraulic fluid is too low, the function will be impaired. Do not use the excavator under full load until the engine
has warmed up sufficiently.
Do not leave the bucket or bulldozer blade raised, as someone could accidentally touch the levers
and cause serious accidents. Lower all attachments to the ground, otherwise accidents may occur.
WARNING
23
CONTROLS
CHECKING THE CONTROLS DURING OPERATION
RUNNING IN THE NEW EXCAVATOR
OPERATION
Switch off the engine immediately in the following cases:
Pay attention to the following points after starting the engine, but before starting work:
• The speed of the engine suddenly increases or decreases.
• Sudden abnormal noise development.
• The exhaust gases suddenly become very dark.
Observe the following controls during operation to ensure normal function.
The service life of the new excavator is influenced by operation and maintenance. Your new excavator was carefully
inspected and tested before it left the factory. Nevertheless, all moving components must be run in during the first 50
hours. Do not work at full speed and load during this time. It is extremely important to run in the excavator correctly in
order to achieve its full performance and service life. The following points should always be observed during the running-in
phase. Do not work at full speed or full load for the first 50 working hours.
• Allow the engine to warm up sufficiently in the cold.
• Do not increase the engine speed more than necessary.
OIL CHANGE DURING THE RUNNING-IN PHASE
STARTING UP
Adjusting the operator's seat
Lubricating oil plays a particularly important role during the running-in phase of the excavator.
The various moving parts have not yet been run in, so that many fine metal particles develop which can cause damage or
shorten the service life of many components. Pay attention to the intervals between oil changes and carry them out
sooner rather than later. See "Care and maintenance" for more details on lhgn.
After adjusting the seat, make sure that the seat adjustment is engaged.
1. Move forwards and backwards: Move the seat forwards and backwards while holding the adjustment lever.
2. Move the locking lever to the "unlock” position.
3. Move the locking lever to the "unlock” position and lift the lower side of the bucket 20 cm to 40 cm off the ground.
Push the right-hand handle bar forwards if the engine stops suddenly so that the bucket falls down
and there are no malfunctions that could lead to accidents due to the bucket falling down.
WARNING

OPERATING THE BOOM
To raise the boom, pull the operating lever of the boom backwards. The boom is equipped with a damping cylinder that
prevents the excavated material from falling out of the bucket. If the hydraulic oil temperature is low (e.g. immediately
after starting the engine), the damper function only starts with a slight delay (approx. 3 to 5 seconds). This is due to the
viscosity of the hydraulic oil and is not a sign of a malfunction.
27
CONTROLS
When lowering the boom, make sure that it does not hit the dozer blade and that the excavator teeth
do not touch it.
ATTENTION
OPERATING THE ARM
Pull the left operating lever for the attachment backwards and the arm is retracted. Push the operating lever forwards to
extend the arm.
OPERATING THE BUCKET
To dig with the bucket, move the operating lever for the right attachment from the "Neutral" position to the left. Move the
operating lever to the right and the bucket is pushed outwards and the contents are poured out.
1. Tilt the operating lever to the left and the upper superstructure will rotate to the left.
2. Tilt the operating lever to the right and the upper superstructure will rotate to the right.
Keep the work area clear!
SWIVELLING OPERATION
28
CONTROLS
When moving the arm, the movement may pause for a brief moment if the arm is in a vertical posi-
tion. This is because the maximum load on the arm and bucket is reached in this position and the
hydraulic pressure in the cylinder is not high enough. This is a characteristic of the hydraulic
system and not a sign of a malfunction.
ATTENTION
Hen working in groups, always let the others know in advance what you intend to do.
ATTENTION
Never move the left attachment operating lever abruptly from right to left (or vice versa). Accord-
ing to the law of inertia, this causes a shock load on the swivel motor gearbox and the part-turn
motor. In addition, the service life of the excavator is shortened. Remove the swiveling locking pin
before carrying out swiveling operations.
IMPORTANT!
SWIVELLING THE OUTRIGGER
1. Press the pedal at the front to swivel the boom to the left.
2. Press the pedal at the rear to swivel the boom to the right.

31
OPERATIONS
If the crawlers become clogged with sand or stones when working on soft ground, lift a crawler
using the boom, arm and bucket and allow the crawler to turn to shake off sand and stones.
IMPORTANT!
32
OPERATIONS
If the excavator gets stuck in the mud while travelling on muddy ground and cannot move, it should
be lifted to a safe area using the sling as shown in the illustration below.
IMPORTANT!
The excavator must not be driven on muddy roads if the swiveling platform is perpendicular to the
crawlers. Otherwise the crawlers can get stuck in the mud.
IMPORTANT!
CHANGE OF DIRECTION
TURNING ON THE SPOT
Do not change direction on steep slopes. The excavator could topple over. Watch out for people in
the work area before changing direction.
CAUTION
If the dozer blade is facing backwards, the direction of rotation is reversed. (For example, press the left (right) lever
forwards and the crawler on the right (left) from the operator's point of view moves backwards towards the operator.)
Note:
The illustrated movement shows the turning movement with the dozer blade pointing for wards.

2. When reversing, set the left drive lever to the neutral position and the excavator will turn to the right.
35
MAINTENANCE
TURNING ON THE SPOT
If both drive levers are activated in opposite directions, both crawlers rotate at the same speed in opposite directions.
The axis of rotation is the center of the excavator.
36
MAINTENANCE
If the excavator is parked on a slope or left unattended, place the bucket on the ground and all
operating levers in the neutral position. Block the crawlers with wedges.
WARNING
DRIVING UPHILL AND DOWNHILL
PARKING ON SLOPES
When driving uphill, keep the lower edge of the bucket approx. 8 in to 16 in above the ground. Even if the excavator does
not slip easily because of the crawlers, it is safer to let the bucket glide over the ground when travelling downhill. Always
select a low speed when travelling uphill and downhill.
37
MAINTENANCE
[DRIVING UPHILL] [DRIVING DOWNHILL]
8-16 in
Clean the machine after work and lubricate all moving parts. Check the oil level.
CAUTION
Do not attempt to shake off soil adhering to the bucket as explained below. This can damage the machine.
Adhering soil can be shaken off when the bucket is emptied by moving the bucket to the maximum stroke of the cylinder.
If this is not enough, extend the arm as far as possible and move the bucket backwards and forwards.
Do not shoot at the dozer blade with the boom cylinder! Ensure that the boom cylinder does not hit the dozer blade when
carrying out deep excavation work. If necessary, swivel the upper carriage so that the dozer blade is at the rear of the
machine.
Be careful when retracting the bucket! Avoid hitting the dozer blade when retracting the bucket (for driving or transport).
Avoid collisions! When moving the excavator, take care that the dozer blade does not collide with obstacles such as rocks
etc.
Such collisions can significantly shorten the service life of the leveling blade and the cylinder.
Support the machine correctly! Lower the dozer blade completely to the base when stabilizing the machine with the level-
ing blade.
If water or mud reaches over the top of the crawlers, the swivel bearing, the gearbox of the swivel motor and the sprocket
can come into contact with mud, water and other foreign bodies.
The excavator must be thoroughly washed with high pressure after each use.
• Thoroughly clean the area around the swivel bearing, the swivel motor gearbox and the gear rim to remove foreign
objects.
• Carefully refer to the operator's manual for the correct lubrication procedures for the swivel bearing, swivel motor
gearbox and gear rim.
• Reattach the protective cover if it has been removed beforehand.
Preparation for operation in cold weather
1. Replace the engine and hydraulic oil with grades with viscosities suitable for cold weather.
2. If the battery is not sufficiently charged, battery performance will drop in cold weather and the battery may freeze.
Make sure that the battery is at least 75% charged after use so that the battery fluid does not freeze. To simplify the next
start, we recommend storing the battery in closed or heated rooms.
38
MAINTENANCE
Do not attempt to break concrete or rock by swiveling the buckets sideways. Also avoid moving
piles of earth by swiveling the bucket sideways. Avoid the following activities at all costs:
• Lifting by utilizing the machine's gravity.
• Compacting gravel or soil by dropping the bucket.
• Lifting with the aid of the machine's driving energy.
IMPORTANT!
IMPORTANT NOTES ON OPERATING THE EXCAVATOR
•Place the excavator on hard, level ground.
•Lower the attachments and the dozer blade onto the base.
•Switch off the engine.
•Secure all operating levers.
•Remove the key.
Clean the excavator thoroughly after work and wipe it dry. Otherwise, mud and soil can freeze on the crawlers when the
temperature drops below 0°C. Then the excavator cannot be put into operation. Store the excavator in a dry place or on
wooden planks or mats if this is not possible. If the excavator is stored on damp or muddy ground, the crawlers may freeze
overnight. Then the excavator cannot be put into operation. In addition, the piston rods of the hydraulic cylinders must be
rubbed dry. Otherwise, serious damage may occur if dirty water penetrates the seals.
39
MAINTENANCE
AFTER COMMISSIONING
TRANSPORTING THE EXCAVATOR ON A LORRY
1. Observe all regulations regarding the transport of excavators on public roads.
2. Use sufficiently long and stable ramps when loading onto a lorry. (For details, see "TRANSPORTING THE EXCAVATOR ON
A LORRY".) The machine can also be lifted onto the lorry. (For details, see “IF TING THE EXCAVATOR”.)
3. Do not change the direction of travel and prevent yourself from overturning. Therefore, do not attempt to swivel the
attachment across the loading ramps.
4. Swivel the upper carriage to the rear of the lorry Lower the attachment onto the loading surface, release the pressure
from the hydraulic system and secure the boom with the lever. Block the crawlers with blocks and tie down the excavator.

out wooden planks on a level surface, place the excavator on them and cover it completely.
2. Change the oil and lubricate the excavator.
3. Lubricate the visible sections of the piston rods particularly well.
4. Remove the battery and store it indoors.
Follow the procedures below if the machine is to be put into operation after a long period of storage.
1. Wipe the grease off the hydraulic cylinder rods.
2. Switch on the engine and activate the attachments and the drive mechanism without load to allow the hydraulic oil to
circulate. (If the machine is stored for longer than one month, carry out steps (1) and (2) every month.)
Do not clean the excavator with the engine running.
CAUTION
To avoid the risk of exhaust poisoning, do not run the engine in a closed building without good
ventilation.
CAUTION
Remove the key from the ignition lock during storage to prevent unauthorized persons from oper-
ating the excavator and injuring themselves.
CAUTION
45
ACCESSORIES
Wash the excavator with the engine switched off. If you wash the excavator while the engine is
running, water can enter the air filter through the inlet and cause engine problems. Wash the exca-
vator carefully to avoid splashing water over the air filter.
IMPORTANT!
STORAGE
Place the machine on a level, firm surface before starting maintenance work. Lower the attachments to the ground, stop
the engine and release the cylinder pressure by operating the levers. When dismantling hydraulic parts, ensure that the
hydraulic oil has cooled down sufficiently to prevent burns. Start the maintenance work carefully, i.e. loosen the screws
slowly so that no oil splashes out.
1. Allow the excavator to cool down sufficiently before working on the engine, the exhaust system, the heat protection
system and the hydraulics.
2. Always switch off the engine when filling it with petrol. Avoid spilling and overfilling with petrol.
3. Smoking is prohibited when refueling and handling the battery! Keep sparks and fire away from the fuel tank and
battery. Flammable gases escape from the battery.
4. If the battery is empty, the machine can be started by pulling the cable.
5. Avoid short-circuiting the battery. Always remove the earth cable first and connect the positive cable first.
6. Have a first aid kit and a fire extinguisher ready at all times.
7. Leaking hydraulic fluid has sufficient pressure to penetrate the skin and cause serious injury. Leaks from tiny holes can
be completely invisible. Never check for possible leaks with your bare hands. Always use a piece of wood or cardboard.
We recommend the use of a face mask or eye protection. If injuries occur due to leaking hydraulic fluid, contact a doctor
immediately. This liquid can cause gangrene or severe allergic reactions.
8. Do not throw the battery away to prevent battery fluid containing heavy metals from leaking out.
9. Observe all laws and regulations regarding the disposal of used oil, coolants, solvents, hydraulic fluids, battery acid
and batteries.
10. To prevent fires, do not heat up the hydraulic components (tanks, pipes, hoses, cylinders) until they have been rinsed
and washed.
11. Use a face mask or eye protection to protect the eyes and respiratory tract from dust and other foreign bodies.
12. Do not crawl under the excavator if it is only supported by the boom and arm or the dozer blade. The excavator can
tip over or sink due to loss of pressure in the hydraulics. Always use safety struts or other suitable supports.
13. Do not use any parts that are lined with asbestos. Do not use these types of parts even if they can be installed.
46
EXPLODED VIEW&PARTS LIST
MAINTENANCE
14. Fire protection. The excavator and some attachments contain components that are very hot under normal working
conditions. The main source of high temperatures is the engine and the exhaust system. The electrical system can be a
source of sparks and flashover if damaged or improperly maintained. The following fire safety guidelines will help you to
keep your devices running efficiently and minimize the risk of fire.
15. Blow off any accumulations of foreign matter near the hot engine exhaust components such as the petrol engine
cylinder head and exhaust manifold as well as the exhaust pipe and silencer more frequently if you are working in difficult
conditions.
16. Remove all flammable debris such as leaves, straw, pine needles, twigs, bark, small wood chips and other flammable
materials from inside the machine's protrusions and lower structures and areas near the engine.
17. Inspect all petrol and hydraulic lines for wear or poor condition. Replace them immediately if they start to leak.
18. Check the electrical cables and connections regularly for damage. Repair any loose or frayed cables before commis-
sioning the machine. Clean all electrical connections and tighten them if necessary.
19. Check the exhaust system daily for signs of leaks. Check for broken pipes and silencers as well as loose or missing
screws, nuts and clamps. If leaks or broken parts of the exhaust system are found, the repairs must be carried out before
commissioning.
20. Always keep a multi-purpose fire extinguisher on or near the machine. Familiarise yourself with the operation of the
fire extinguisher.

Ensure that no foreign objects such as stones get caught in the crawlers. Remove such foreign
objects before adjusting the crawler tension.
IMPORTANT!
Crawler connecting piece
The ends of the rubber crawlers are joined together with a connecting piece. When setting the
crawlers, the connecting piece must be positioned at the top center between the idle roller and the
pinion. If the connecting piece is positioned incorrectly, the crawler will be tensioned too loosely
and further readjustment will be necessary.
IMPORTANT!
After adjusting, turn the crawler once or twice to check the tension.
IMPORTANT!
In addition, the following points must be observed when adjusting the crawlers.
(1) If a crawl er sags more than 0.98 inches (25 mm), it must be readjusted.
(2) Check the tension of the crawlers 30 hours after first use and readjust if necessary. Check and
then adjust every 50 operating hours.
IMPORTANT!

Special instructions for the use of rubber crawlers
1. Change direction as slowly as possible. Avoid turning on the spot to prevent wear and the ingress of dirt.
2. Move the machine a short distance straight backwards if too much dirt and sand is blocking the crawlers. The soil and
sand will then fall out and you can change direction.
3. Avoid using the rubber crawlers on riverbeds, stony surfaces, reinforced concrete and iron plates. The rubber can be
damaged and wear increased.

Regular replacement f important components
Also check the petrol and hydraulic lines during the following regular inspections.
To ensure safe operation, we strongly advise you to inspect and maintain the machine at regular intervals. For additional
safety, ask your dealer to replace the following important components.
These parts are subject to material deterioration or wear out over time. During regular inspections, it is difficult to assess
how badly they are damaged. They must therefore be replaced with new parts, even if the wear and tear is not visible after
a certain period of use.
If a component is worn out before the end of its service life, it must be repaired or replaced in the same way as other parts.
If a hose clamp is deformed or torn, it must be repaired.
Check the following points for hydraulic lines that are not replaced regularly. Tighten or replace them if you notice any
abnormalities.
When replacing the hydraulic lines, also replace their O-rings and seals. Contact your dealer to replace important parts.

It is not permitted to lift loads greater than those listed in the lifting capacity tables.
WARNING
The values specified in the tables only apply on a level, hard surface. When lifting on soft ground,
the machine can tip over because the load is only concentrated on one part of the machine. The
table values are calculated at the end of the arm without the bucket. To find the permitted loads for
machines with a bucket, the weight of the bucket must be taken off the values in the table.
WARNING
CHECKING THE PETROL LINE
1. The lifting capacity is based on ISO 10567 and does not exceed 75% of the static tipping load of the machine or 87%
of the hydraulic lifting capacity of the machine.
2. The strokes are as follows:
The load point corresponds to the front bolt part of the arm.
The machine positions are (i) over front (top plate), (ii) over front (bottom plate), and (iii) over side.
The working cylinder is the boom cylinder.
3. The excavator bucket, hook, loop and other lifting accessories are considered in the loads.
