3.5 Introduction

3.6 Safety-relevant parts

Please refer to the 803 spare parts catalogue for the article numbers of the 2 available service packages (for 50 and 500 operating hours).

Operational readiness and the service life of ma chines are h eavily depen dent on maintenan ce. It is therefore in the interest of the machine owner to perform the mandatory maintenance. Bear in mind the following points before performing servicing and maintenance:

• Chapter 2 “SAFETY INSTRUCTIONS” in the Operator’s Manual

• The Operator’s Manuals of the attachments. Perform the prescribed inspections and rectify any disorders before putting the machine

into operation. Secure the open engine cover and other open covers appropriately. Do not open the

engine cover and other covers on slopes or in strong wind. When using compressed air, dirt and debris can be blown into your face. Therefore, wear

safety glasses, protective masks and clothing when using compressed air.

Daily servicing and maintenance, and maintenance according to maintenance plan “A” must be performed by a specifically trained person. All other maintenance must be performed by trained and qualified personnel only.

The following maintenance plans indicate the maintenance to be performed. This is necessary to ensure optimal functioning.

– see Maintenance plan (overview) on page 3-8.

Immediately repair or replace parts that are already damaged or not working properly before they are due for replacement.

Safety-relevant parts may only be repaired or replaced by a Wacker Neuson dealer or a Wacker Neuson service center.

Parts Interval

Hydraulic hoses Replace hydraulic hoses every 6 years from the date of manufac-

ture, even if they do not seem to be damaged.

Seat belt No replacement necessary. Replace the seat belt after an accident.

Specific safety instructions

Refueling

Maintenance

• Extreme caution is essential when handling fuel – increased fire hazard!

• Never perform work on the fuel system near open flames or sparks!

• Do not smoke when working on the fuel system or when refueling!

• Before refueling, stop the engine and remove the starting key!

• Do not refuel in closed rooms!

• Wipe away fuel spills immediately!

• Keep the machine clean to reduce the fire hazard!

Filler inlet A for the fuel tank is located under the engine cover, on the left in travel direction.

All work involving fuel carries an increased

Fire and poisoning hazard!

☞Do not refuel in closed rooms ☞Never perform work on the fuel system near open flames or sparks

Use a suitable container to collect the fuel as it drains and dispose of it in an environmentally friendly manner!

Do not run the fuel tank completely dry. Otherwise, air is drawn into the fuel system. This requires bleeding the fuel system – see Bleeding the fuel system on page 3-15.

Fill up the tank with the correct fuel type at the end of each working day. This prevents condensation water from forming in the fuel tank over night. Do not fill the tank completely but leave some space for the fuel to expand.

Stationary fuel pumps

General

Only refuel from stationary fuel pumps. Fuel from barrels or cans is usually dirty. Even the smallest particles of dirt can cause

• Increased engine wear

• Malfunctions in the fuel system and

• Reduced effectiveness of the fuel filters

Refueling from barrels

If refueling from barrels cannot be avoided, note the following points (see fig. 2):

• Barrels must neither be rolled nor tilted before refueling

• Protect the suction pipe opening of the barrel pump with a fine-mesh screen

• Immerse it down to a max. 150 mm (5.9 in) above the bottom of the barrel

• Only fill the tank using refueling aids (funnels or filler pipes) with integral microfilter

• Keep all refueling containers clean at all times

• Turn the starting key to the first position

• Wait about 5 minutes while the feed pump bleeds the fuel system automatically

• Start the engine

• Check for leaks after starting the engine

• Let the fuel system run by performing a test run of 5 minutes at idling speed

If the engine runs smoothly for a while and then stops, or if it does not run smoothly:

• Stop the engine

• Raise the lock lever

• Remove the starting key

• Bleed the fuel system again as described above

• Have this checked by authorized personnel if necessary

Fuel prefilter with water separator

Check the fuel prefilter as follows:

☞Remove the right-hand chassis cover in order to be able to see the water separator. ☞If the red indicator ring rises to position C ☞Unscrew thread A

➥Empty the receptacle ➥Fit the receptacle back on again

☞Screw thread A back on again ☞Bleed the fuel system – see chapter Bleeding the fuel system on page 3-15

3.9 Cooling 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

☞Contact a Wacker Neuson dealer immediately. Have a line replaced if one of the fol-

lowing problems is detected:

☞Damaged or leaky hydraulic seals ☞Worn or torn shells or uncovered reinforcement branches ☞Expanded shells in several positions ☞Entangled or crushed movable parts ☞Foreign bodies jammed or stuck in protective layers

Dirty hydraulic oil, lack of oil or wrong hydraulic oil –

Risk of serious damage to the hydraulic system!

☞Take care to avoid dirt when working! ☞Always add hydraulic oil by means of a screen or the return filter! ☞Only use authorized oils of the same type

– see “Fluids and lubricants” on page 3-2

☞Always add hydraulic oil before the level gets too low

– see “Adding hydraulic oil” on page 3-38

☞If the hydraulic system is filled with biodegradable oil, then only use biode-

gradable oil of the same type for adding oil – observe the sticker on the hydraulic oil reservoir!

☞Contact your dealer immediately if the hydraulic system filter is contami-

nated with metal chippings. Otherwise, follow-on damage can result!

Collect drained hydraulic oil and biodegradable oil in a suitable container! Dispose of drained oil and used filters by an ecologically safe method. Always contact the relevant authorities or commercial establishments in charge of oil disposal before disposing of biodegradable oil.

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
