3.9Cooling system
Specific safety instructions
The radiator is located in the engine compartment, on the right of the engine.
The coolant reservoir is also located in the engine compartment, behind the engine
• 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 mainte-
nance 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 con-
tact your dealer!
☞ Never add cold water/coolant if the engine is warm!
☞ After filling the coolant reservoir, make a test run with the engine and check the cool-
ant level again after stopping the engine
• 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 %.
According to specified standard
– see chapter 3.1 Fluids and lubricants on page 3-2
☞ Observe the coolant compound table
– see chapter 2.9 Coolant compound table on page2-8
☞ Do not use cooler cleaning compounds if an antifreeze compound has been added to
the coolant – otherwise this causes sludge to form, which can damage the engine
• Once you have filled the coolant reservoir:
☞ Test run the engine
☞ Stop the engine
☞ Let the engine cool down
☞ Check the coolant level again
Use a suitable container to collect the coolant as it drains and dispose of it in
an environmentally friendly manner!

Specific safety instructions
• Release the pressure in all lines carrying hydraulic oil prior to any maintenance and
repair work. To do this:
• Lower the boom or the attachment to the ground
• Move all control levers of the hydraulic control valves several times
• Raise the lock lever
• Hydraulic oil escaping under high pressure can penetrate the skin and cause serious
injury. Always consult a doctor immediately even if the wound seems insignificant –
otherwise serious infections could set in!
• If the hydraulic oil in the sight glass is cloudy, this indicates that water or air has
penetrated the hydraulic system. This can cause damage to the hydraulic pump!
• Oil or fuel flowing out of high pressure lines can cause fire or malfunctions, and serious
injury or damage to property. Interrupt work immediately if loose nuts or damaged
hoses and lines are detected

Checking hydraulic pressure lines
Specific safety instructions
Caution when checking hydraulic lines, especially when searching for leaks.
Hydraulic oil escaping under high pressure can penetrate the skin and cause
serious injury.
Injury hazard!
☞ Always consult a doctor immediately, even if the wound seems insignificant
– otherwise serious infections could set in!
☞ Always observe the following instructions:
• Retighten leaking threaded 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 with new ones!
• Never search for leaks with your bare hands, but wear protective gloves!
• Use paper or wood to check for minor leaks. Never use an unprotected
light or open flame!
• Have damaged flexible lines replaced by a Wacker Neuson service
center only!
• 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 your 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 date of manufacture (month or quarter and year) is indicated on the flexible line.
Example:
The indication “1 Q/04” means manufactured in the 1st quarter of 2004.

Excessive tension of the tracks causes serious damage to the cylinder and the
track.
☞ Tighten the tracks only up to the prescribed measuring distance
Tightening the tracks
☞ Inject grease with the pump through lubricating valve A
☞ Check the tension is correct by starting the engine, letting it run at idling speed and
slowly moving the machine forward and reverse and switching it off again
☞ Check the tension of the tracks again
➥ If it is not correct:
☞ Adjust again
☞ Should the track still be slack after injecting more grease, replace the track or the seal
in the cylinder. Contact a Wacker Neuson dealer in this case
Reducing tension
• Draining grease in a way different from the one described below is very dangerous.
Also bear in mind the safety instructions on this page
☞ Slowly open the lubricating valve A by 1 turn to allow the grease to flow out.
☞ Place a suitable container underneath to collect the grease
➥ The grease flows out of the groove of the lubricating valve
☞ Retighten lubricating valve A

Caution!
3.20 General maintenance
Cleaning
Cleaning the machine is divided into 2 separate areas:
• Exterior of the machine
• Engine compartment
The wrong choice of cleaning equipment and agents can impair the operating safety of the
machine on the one hand, and on the other undermine the health of the persons in charge
of cleaning the machine. It is therefore essential to observe the following instructions.
General instructions for all areas of the machine
Cleaning with washing solvents
• Ensure appropriate room ventilation
• 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
Control stand
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 appropriate room ventilation
• Do not use unprotected lights or open flames
• Do not smoke
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

Exterior of the machine
Danger!
Caution!
Engine compartment
Maintenance
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
Clean the engine only when it is at a standstill –
Injury hazard!
☞ Stop the engine before cleaning
Threaded fittings and attachments
Pivots and hinges
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 leads to
engine damage!
All threaded fittings must be checked regularly for tightness, even if they are not listed in
the maintenance schedules. This applies in particular to:
☞ Engine fastening screws
☞ Fastening screws on the hydraulic system
☞ Bucket teeth and pin fastenings on the attachment
☞ Rollbar fastening screws
Retighten loose connections immediately. Contact a Wacker Neuson service center if necessary.
All mechanical pivot points on the machine (door hinges, joints, for example) and fittings
(door arresters, for example) must be lubricated regularly, even if they are not listed in the
lubrication plan.
