Starting battery
Safety instructions
• Never jump-start the engine if the battery of the machine is frozen – danger of explosion!
☞ Dispose of a frozen battery!
• The excavator must not touch the jump-starting vehicle when connected with jump leads – sparking hazard!
• The external power source must deliver 12 V; higher supply voltages will damage the electrical system of the vehicles!
• Use only authorized battery jumper cables which conform to the safety requirements and which are in perfect condition!
• The jump lead connected to the positive + terminal of the starting battery must never be brought into connection with electrically conductive vehicle parts – risk of short circuit!
• Route the jump leads so that no one can catch on rotating components in the engine compartment!
Procedure
☞ Drive the jump-starting vehicle close enough to the machine so that the jump leads can reach to connect the two batteries
☞ Let the engine of the jump-starting vehicle run
☞ First connect one end of the red jump lead ( + ) to the + terminal of the empty battery, then connect the other end to the + terminal of the starting battery
☞ Connect one end of the black jump lead (
–
) to the
–
terminal of the starting battery
☞ Connect the other end of the black cable (
–
) to a solid metal component fimly screwed on the engine block or onto the engine block itself. Do not connect it to the negative terminal of the empty battery, as otherwise explosive gas emerging from the battery can ignite if sparks are formed!
☞ Start the engine of the machine with the empty battery
Once the engine has started:
☞ With the engine running, disconnect both jump leads in exactly the reverse order (first remove the
–
terminal, then the
+
terminal) – this prevents sparking in the vicinity of the battery!

3.7 Machine travel on slopes
Accident hazard due to tipping over or slipping of machine!
Can cause serious injury or death.
• Travel on slopes only on firm and level ground.
• Travel on slopes only with the telescopic travel gear extended (normal operation).
• Never exceed the stability limits of the machine (maximum gradient angle
15°, maximum lateral angle of inclination 10°).
• Raise the boom about 20 – 30 cm (8 – 12 in) off the ground and position it straight ahead at the center of the machine. In an emergency, lower the boom immediately to increase stability.
• Do not reverse down slopes.
• Do not turn or swivel the upper carriage and the boom when driving downhill or uphill with a full attachment.
• Traveling diagonally on slopes is prohibited.
• Traveling on slopes is prohibited if a zero-emission power unit (HPU8, for example) is raised with the stabilizer blade.
Stones and the humidity in the upper layer of the ground can drastically affect machine traction and stability.
The machine can slip sideways on gravel or loose, rocky soil. The stability of the machine can be reduced on rough terrain.
Newly filled or muddy ground can give away under the weight of the machine, or the tracks can dig into the ground and increase the angle of the machine (maximum gradient angle and maximum lateral angle of inclination).
If the engine dies as you travel on a slope, immediately put the control levers to neutral position and start the engine again.
Bear in mind the following under all circumstances when driving uphill or downhill:
• Keep the travel levers near the neutral position.
• Perform slow and smooth travel movements.
• Avoid sudden travel movements.
• Reduce the engine speed.
The machine can slip even on gentle slopes if it travels across grass, leaves, humid metal surfaces, frozen ground or ice.
Preparations for traveling on slopes
Always travel straight ahead when driving uphill or downhill.
When changing position, do not exceed a maximum gradient angle of 15° and a maximum lateral angle of inclination of 10°.

3.13 Working with the machine
General safety instructions
• Machine operation is only allowed when seated on the seat
– see chapter 2.6
Safety instructions regarding operation on page 2-6.
• Do not use the machine in areas with danger of falling objects!
• Never drive up to the edge of a pit from outside – danger of cave-in!
• Never undermine the foundations of walls – danger of collapse!
• Do not dig under projecting ground. Stones or the projecting earth can fall onto the machine.
• Do not excavate deeply under the front side of the machine. The ground under the machine could collapse and cause it to tip over.
• In order to leave the control stand more easily under especially difficult circumstances, position the tracks parallel to the roadside or to the uphill slope with the drive pinion behind the operator.
• Do not perform demolition work below the machine, this could cause the machine to tip over.
• When working on roofs or similar structures, check the resistance and the structure before starting work. The building can collapse, causing serious/fatal injury and serious damage.
• Do not place the machine directly underneath the workplace during demolition, otherwise demolished parts can fall onto the machine or the building can collapse, causing serious/fatal injury and serious damage.
• Do not use the impact force of the attachment to perform demolition work. Falling demolished parts (parts of buildings, for example) can cause injury and/or damage to property and/or the machine.
• In general the machine is more liable to tip over if the boom is positioned laterally than if it is positioned parallel to the longitudinal axis of the machine.
• The machine can lose its balance and tip over if a demolition hammer or other heavy attachment is used. Proceed as follows to perform work both on level ground and on slopes:
☞ Never lower, turn or set down the attachment abruptly.
☞ Do not extend or retract the boom abruptly, otherwise the machine can tip over.
• Do not raise the bucket over the heads of persons, the seat or the cabs of trucks or other means of transport. Material can fall out, or the bucket can knock against the truck and cause serious/fatal injury and serious damage.

3.19 Pressure release on the auxiliary hydraulics
NOTICE
Before connecting or removing hydraulic lines from an attachment with hydraulic functions, ensure that the hydraulics are not under pressure!
Ensure that no one is in the danger zone of the machine
Information!
The hydraulic system of the machine is still pressurized even when the engine is not running! The hydraulic quick couplers can be released, however they cannot be re-attached due to the residual pressure in the lines.
• Release the pressure.
• Release the pressure in the sections of the system and hydraulic lines that are to be opened before starting setup or repair work, for example fitting/removing an attachment!
Releasing pressure
Release the pressure as follows:
☞ Park the machine on level and horizontal ground.
☞ Lower the boom and the attachment completely to the ground.
☞ Stop the engine.
☞ Lower (unlock) the lock lever.
☞ Move the control levers in all directions repeatedly.
➥ The pressure in the system sections that have been actuated is released. This can be seen by the brief movement the hoses make as the pressure is actually released.
➥ Uncouple the attachment immediately after the pressure has been released, otherwise pressure can be created again!
3.20 Re-equipping attachments
Re-equipping the attachments is described below for a bucket. If you are fitting or removing attachments with their own hydraulic functions – grab or offset bucket, for example – you must follow the special information given in the Operator’s Manual of the attachment.

Maintenance
• Dirt on the radiator fins reduces the radiator’s heat dissipation capacity!
To avoid this:
☞ Clean the outside of the radiator at regular intervals. Use oil-free compressed air (2 bar max.) to clean. Maintain a certain distance from the radiator to avoid damage to the radiator fins. Refer to the maintenance plans in the appendix for the cleaning intervals.
☞ In dusty or dirty work conditions, clean more frequently than indicated in the maintenance plans.
• An insufficient coolant level reduces the heat dissipation capacity as well and can cause engine damage! Therefore:
☞ Check the coolant level at regular intervals. Refer to the maintenance plans in the appendix for the intervals
☞ If coolant must be added frequently, check the cooling system for leaks and/or contact a Wacker Neuson service center!
☞ Never add cold water/coolant if the engine is warm!
• The use of the wrong coolant can destroy the engine and the radiator. Therefore:
☞ Add enough antifreeze compound to the coolant – but never more than 50 %. If possible use brand-name antifreeze compounds with anticorrosion additives!
☞ Observe the coolant compound table
Coolant compound table on page 6-9.
☞ Do not use radiator cleaning compounds if an antifreeze compound has been added to the coolant – otherwise this causes sludge to form that can damage the engine.
• Once you have filled the coolant reservoir:
☞ Test run the engine.
☞ Stop the engine.
☞ Raise the lock lever.
☞ Remove the starting key.
☞ Let the engine cool down.
☞ Check the coolant level again.

Maintenance
Important information on the use of biodegradable oil
• Use only the biodegradable hydraulic fluids that have been tested and released by
Wacker Neuson. Always contact a Wacker Neuson dealer before using other products that have not been recommended. In addition, ask the oil supplier for a written declaration of guarantee. This guarantee is applicable to damage occurring on the hydraulic components that can be proved to be due to the hydraulic fluid.
• Use only biodegradable oil of the same type for adding oil. In order to avoid misunderstandings, a label providing clear information is located on the hydraulic oil reservoir
(next to the filler inlet) regarding the type of oil currently used!
The joint use of two different biodegradable oils can severely affect the quality of one of the oil types. Therefore when using a different kind of biodegradable oil, ensure that the remaining amount of initial biodegradable oil does not exceed the indications of the manufacturer of biodegradable oil.
• Do not add mineral oil – the content of mineral oil should not exceed 2 % in order to avoid foaming problems and to ensure biological degradability.
• When running the machine with biodegradable oil, the same oil and filter replacement
intervals are valid as for mineral oil – see chapter 5.16
Maintenance plan (overview) on page 5-38.
• Always have the condensation water in the hydraulic oil reservoir drained by a Wacker
Neuson service center before the cold season. The water content may not exceed
0.1 % by weight.
• The instructions in this Operator’s Manual concerning environmental protection are also valid for the use of biodegradable oil.
• If additional hydraulic attachments are installed or operated, use the same type of biodegradable oil for these attachments to avoid mixtures in the hydraulic system.
Subsequent change from mineral oil to biodegradable oil must be performed by a Wacker
Neuson service center or your Wacker Neuson dealer.

Checking hydraulic pressure lines
Specific safety instructions
Injury hazard when checking hydraulic pressure lines!
Can cause serious injury or death.
• Wear protective gloves and safety glasses.
• Search for hydraulic leaks with a piece of paper, for example.
• Always consult a doctor immediately, even if the wound seems insignificant. Hydraulic oil causes blood poisoning.
• Observe the following instructions:
• Retighten leaking screwed fittings and hose connections only when the system is not under pressure; in other words, release the pressure before working on pressurized lines!
• Never weld or solder damaged or leaking pressure lines and threaded fittings. Replace damaged parts (or have them replaced) with new ones
• Never use an unprotected light or open flame to check for minor leaks!
• Have damaged flexible lines replaced by a Wacker Neuson service center only!
• Do not remove protective hoses from hydraulic hoses.
• Leaks and damaged pressure lines must be immediately repaired or replaced by a
Wacker Neuson service center or after-sales personnel. This not only increases the operating safety of the machine but also helps to protect the environment.
• Replace hydraulic hoses every 6 years from the date of manufacture, even if they do not seem to be damaged.
In this respect, we recommend that you observe all the relevant safety regulations for hydraulic lines, as well as the safety regulations regarding accident prevention and occupational health and safety in your country. Also observe DIN 20066, part 5.
The article number is marked on the clamping section, and the date of manufacture is indicated on the hose of each hose connection.

• Wear suitable protective clothing
• Do not use flammable liquids, such as gasoline or diesel
Cleaning with compressed air
• Work carefully
• Wear safety glasses and protective clothing
• Do not aim the compressed air at the skin or at other people
• Do not use compressed air for cleaning your clothing
Cleaning with a high-pressure cleaner or steam jet
• Electrical components and damping material must be covered and not directly exposed to the jet
• Cover the hydraulic oil reservoir and the covers of the fuel tank, the hydraulic oil reservoir, etc.
• Protect the following components from moisture:
• Engine
• Electrical components such as the alternator, etc.
• Control devices and seals
• Air intake filters, etc.
Cleaning with volatile and easily flammable anticorrosion agents and sprays:
• Ensure adequate room ventilation
• Do not use unprotected lights or open flames
• Do not smoke

Maintenance
Control stand
Exterior of the machine
Engine compartment
NOTICE
Never use high-pressure cleaners, steam jets or high-pressure water to clean the control stand. Water under high pressure can
• penetrate into the electrical system and cause short circuits and
• damage seals and disable the controls!
We recommend using the following aids to clean the control stand:
• Damp cloth
• Brush
• Water with mild soap solution
Cleaning the seat belt:
• Clean the seat belt (which remains fitted in the machine) with a mild soap solution only.
Do not use chemical agents as they can destroy the fabric!
The following articles are generally suitable:
• High-pressure cleaner
• Steam jet
Burn hazard due to hot engine parts!
Can cause serious injury or death!
• Stop the engine and let it cool down.
• Wear protective equipment.
Injury hazard due to rotating parts!
Can cause serious injury or death!
• Stop the engine before cleaning
NOTICE
When cleaning the engine with a water or steam jet
• The engine must be cold
• and do not point the jet directly at electric sensors such as the oil pressure switch.
The humidity penetrating any such sensors causes them to fail and possibly leads to engine damage!

Technical data
• Reduce vibration to a minimum during long work cycles or when traveling over long distances:
• Use a machine with a suspension system (operator seat, for example).
• Enable the hydraulic oscillation damping if the machine is equipped with tracks.
• If the machine is not equipped with hydraulic oscillation damping, reduce your speed to avoid bumps and jolts.
• Load the machine on a truck or trailer to move between work sites.
• Other risk factors can affect drive comfort negatively. The following measures can improve drive comfort:
• Adjust the operator seat and the control elements to a relaxed body posture.
• Adjust the rearview mirrors to ensure optimal visibility so you can adopt an upright seating position.
• Provide breaks to avoid sitting for long periods.
• Do not jump off the control stand.
• Picking up and raising loads repeatedly must be limited to a minimum.

DANGER
Crushing hazard due to tipping over of machine.
Causes serious crushing or injury resulting in death.
• The authorized lift capacity specified in the table must never be exceeded.
The lowest value applies.
• Get informed on the lift capacity of the attachment before using it.
• If a bucket or attachment (hammer, etc.) is installed, the dead weight and the contents of the bucket must be subtracted from the lift capacity specified in the table. Load density must also be taken into account.
• All lifting gear applications are prohibited with this machine.
NOTICE
If the specified lift capacity is exceeded, danger of damage to property due to tipping over of machine.
• The authorized lift capacity specified in the table must never be exceeded.
The lowest value applies.
Information!
The indications are only approximate values. Attachments, uneven ground and soft or bad ground conditions affect lift capacity. The operator must take these influences into account.
