FUEL HANDLING

General

WARNING! Running an engine in a conﬁned or badly ventilated area can result in death

due to asphyxiation or carbon monoxide poisoning. Do not use the machine in enclosed spaces.

Fuel and fuel fumes are ﬂammable and can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

The exhaust fumes from the engine are hot and may contain sparks which can start a ﬁre. Never start the machine indoors or near combustible material!

Do not smoke and do not place any hot objects in the vicinity of fuel.

Fuel

• Top up with diesel fuel. Gasoline may not be used under any circumstances.

• Use fuel with a cetane rating over 45. Max RME mixing 5% in mineral oil-based fuels.

Winter fuel

When driving in very cold weather operating problems due to parafﬁn precipitation can occur if you run on standard fuel. To counteract this, winter fuel is sold in the climate areas affected. In some regions, different fuel is sold in summer and winter. Ask your fuel supplier and use only winter fuel below 0

°C (+32°F).

Fueling

WARNING! Diesel is highly ﬂammable. Exercise care and refuel outdoors.

Clean the area around the fuel cap.

Tighten the fuel cap carefully after refuelling. If the cap is not properly tightened the cap might vibrate lose and fuel may escape from the fuel tank creating a ﬁre hazard.

Move the machine at least 3 m from the refuelling point before starting it.

The fuel level in the tank is shown by the gauge on top of the tank.

The diesel engine injection system is very sensitive and can be damaged by the slightest contamination. Observe the greatest possible fuel cleanliness. Use only clean containers.

• Clean the area around the fuel cap. Contamination in the tank can cause operating problems.

• When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

• Wipe up any spillage. Materials contaminated by fuel must be moved to a safe location.

• Handle oil, oil ﬁlters, fuel and the battery carefully, of environmental considerations. Follow the local recycling requirements.

Never start the machine:

• If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

• If you have spilled fuel or engine oil on the machine. Wipe off the spill and allow the remaining fuel to evaporate.

• If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.

• Unless the fuel cap is securely tightened after refueling.

Transport and storage

• Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or open ﬂames, for example, from electrical machinery, electric motors, electrical relays/switches or boilers.

• When storing and transporting fuel always use approved containers intended for this purpose.

• Store the machine and fuel in such a way that there is no risk that leaking fuel or fumes can cause any damage.

Fuel which is left to stand for long periods (30 days or more) can leave sticky deposits and interfere with the engine function. Fuel stabiliser is an acceptable alternative to avoid tacky deposits during storage.

• Add stabiliser to the fuel in the tank or the storage container.

• Always use the mixing ratios indicated by the manufacturer.

• Run the engine for at least 10 minutes after adding the stabiliser.

• Allow the engine to cool before refuelling.

• Check the fuel level before each use and leave space for the fuel to expand, because the heat from the engine and the sun may otherwise cause the fuel to expand and overﬂow.

WARNING! Never store a machine with fuel in the tank indoors or in poorly ventilated

spaces where fuel vapour can come in contact with open ﬂames, sparks, or a pilot light such as in a boiler, hot water tank, clothes drier, etc.

Exercise caution when handling fuel. It is highly inﬂammable, and careless use can cause serious injury and damage to property.

Driving on slopes

Driving on slopes is one of the operations where the risk of the driver losing control of the machine or of it overturning is the greatest; this can result in serious injury or death. All slopes demand extra care. If you cannot reverse up a slope or if you feel unsure, do not mow it.

IMPORTANT! Do not drive down slopes with the cutting deck raised.

22 – English

This is what you do

• Remove obstacles such as stones, branches, etc.

OPERATING

• Mow upwards and downwards, not sideways.

• Do not use the machine on ground that slopes more than 10

°.

• Take extra care if any attachments are ﬁtted that can change the stability of the machine.

STARTING AND STOPPING

Before starting

• Read the safety instructions and information concerning the placement of controls and functions before starting.

• Perform daily maintenance before starting as set out in the Maintenance schedule.

IMPORTANT!

The air intake grille in the engine cover must not be blocked by, for example, clothing, leaves, grass or dirt. Impaired cooling of the engine. Risk of major engine damage.

WARNING! Do not modify the machine’s safety devices and check regularly that they

are working properly.

• Localise and mark stones and other ﬁxed objects to avoid collision.

• Avoid mowing a wet lawn. The mowing results will then be poorer.

• Start with a high cutting height and reduce down until the required mowing results are obtained.

• The mowing result will be best with the highest permitted engine speed, see technical data, (the blades rotate rapidly) and low speed (the Mower moves slowly). If the grass is not too high and thick, the driving speed can be increased without noticeably depreciating the mowing result.

• The best lawns are achieved if the grass is cut often. Mowing becomes more uniform and the grass cuttings become more evenly distributed over the surface. The total time consumption is not greater since it is possible to select a higher driving speed without inferior mowing results.

• When the BioClip function is used, it is very important that the mowing interval is not too long.

• Hose down the cutting unit with water underneath each time it is used, avoid using a high pressure washer. The cutting unit should then be put in the service position.

Start the engine

1 Ensure that the bypass valves are closed.

2 Apply the parking brake.

MAINTENANCE AND SERVICE

General

Service

Low season is the most suitable time to perform a service or overhaul of the machine in order to ensure high function safety during high season.

When ordering spare parts state your machine’s purchase year, model, type, and serial number.

Always use genuine parts.

An annual check-up by an authorised servicing dealer is a good way to ensure that your ride-on mower performs at its best the following season.

Cleaning

Clean the machine directly after use. It is much easier to wash off grass cuttings before they dry.

Cleaning the radiator cell package

Clean the radiator with compressed air. Use compressed air blown from the engine compartment through the cell package and back.

• Open the engine cover.

• If necessary, remove the engine cover. For more information, see 'Removing the ride-on mower covers'.

Cleaning the air ﬁlter

If the engine seems to lack power or does not run smoothly this may be because the air ﬁlter is clogged. When driving with a dirty air ﬁlter the engine can suffer from lack of air, so that it does not meet environmental requirements and the engine does not provide full power.

Emptying the particle collector

• Squeeze so that the rubber tabs open and the particles can escape.

Oily dirt can be removed using a cold degreasing agent. Spray on a thin layer.

Rinse at normal water pressure.

Do not direct the jet towards electrical components or bearings.

Do not rinse hot surfaces such as the engine and exhaust system.

It is recommended that you start the engine and run the mower for a short period after cleaning, so that any remaining water is blown off.

Lubricate the machine if necessary after cleaning. Carry out extra lubrication when the bearings have been exposed to a degreaser or a water jet.

IMPORTANT! Avoid using a high pressure washer or a steam cleaner.

There is a major risk of water penetrating into bearings and electrical connections. Corrosion attack can result, which will lead to running problems. Cleaning additives generally aggravate the damage.

Checking the engine’s cooling air intake

• Make sure the radiator grille is free of leaves, grass and dirt.

Cleaning the ﬁlter cover

• Loosen the two fasteners holding the ﬁlter cover and remove it.

• Clean the inside of the lid. It can be washed with soapy water and blown with compressed air when the lid is removed.

• Replace the air ﬁlter cover, ensure that the particle collector is facing downwards.

MAINTENANCE AND SERVICE

Change coolant

Correct coolant level is important for the cooling system to function properly. Therefore the coolant level must be checked regularly.

The coolant should be visible when the ﬁller cap is removed.

Repeated coolant loss normally indicates leakage. The cooling system should be checked by a professional. It is not sufﬁcient just to top up with coolant.

If the engine boils, coolant will be lost. Open the radiator cap and allow the coolant to cool down. Allow the engine cool before ﬁlling.

The cooling system must not be ﬁlled with salt water, as this will cause corrosion damage to the engine.

Replace coolant if it is discoloured or cloudy

The cooling system must then be thoroughly ﬂushed.

Use only glycol-based antifreeze approved to BS 6580:1992 or ASTM D 3306-89 or AS 2108-1977 (indicated on the packaging).

The antifreeze must be intended for alloy engines.

Your Husqvarna supplier can provide the right type of antifreeze.

Use antifreeze all year round and even in climates where there is no risk of frost.

Antifreeze contains additives that protect the engine cooling system against corrosion

The coolant and antifreeze should be changed at least every two years.

• Remove the ﬁller cap.

Fill only with antifreeze and water mixed according to the following table.

Propylene glycol (MPG) Water Freezing point

60 % 40 % -47 °C / -53 °F

50 % 50 % -37 °C / -35 °F

40 % 60 % -25 °C / -13 °F

IMPORTANT! Never add cold coolant to a hot engine. Risk of comprehensive engine damage.

• Check the coolant when the engine has run for a few minutes after ﬁlling. There may have been air in the system that has been released.

Inspecting the mufﬂer

WARNING! The mufﬂer gets very hot in use and remains so for a short time afterwards.

Do not touch the mufﬂer if it is hot!

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

• Check regularly that the mufﬂer is complete and secured correctly.

WARNING! Do not open the cap quickly when the engine is hot without ﬁrst

releasing the pressure by partially opening the cap. Risk of burns. Wear protective gloves and goggles.

WARNING! Antifreeze and coolant are dangerous to health. Keep them in storage

in labelled containers and away from children and animals.

• When emptying loosen the lower hose to the radiator.

40 – English

Checking the tyre pressure

The tyre pressure should be 1.5 bar/150 kPa/22 PSI for all wheels for best bearing capacity.

IMPORTANT! Different tyre pressures on the front tyres will result in the blades cutting the grass at different heights.

MAINTENANCE AND SERVICE

Check the battery

WARNING! Lead-acid batteries produce explosive gases. Avoid sparks, open ﬂames

and smoking close to batteries.

Always wear protective glasses in the vicinity of batteries.

The machine is equipped with a maintenance-free battery. The battery has a service window showing different colours.

• White = Charge battery

• Green = OK.

• Red = Change battery.

Clean the battery and holder with soap/water solution.

A discarded or replacement battery should be handled as hazardous waste.

Replacement of fuel ﬁlter

P520 D, P525 D has two fuel ﬁlters. A pre-ﬁlter and main ﬁlter.

Replace the fuel ﬁlter every 100 hours (at least once per season) or more often if it is clogged.

The pre-ﬁlter is located under the battery box and is replaced as follows.

Replacing the air ﬁlter

WARNING! The exhaust system is hot. Let it cool before starting to replace the air ﬁlter.

If the engine seems to lack power or does not run smoothly this may be because the air ﬁlter is clogged. It is therefore important to replace the air ﬁlter at regular intervals (see Maintenance/Maintenance Schedule for the correct service interval).

Replace the air ﬁlter as follows:

1 Open the engine cover.

2 Loosen the two fasteners holding the ﬁlter cover and

remove it.

IMPORTANT!

Never run the engine without the air ﬁlter ﬁtted.

Poorly ﬁltered inlet air is a main factor contributing to engine wear. Replace the air ﬁlter according to the service schedule or more often in dusty conditions

The ﬁlters must not be oiled. They must be ﬁtted dry.

3 Remove the ﬁlter cartridge from the ﬁlter housing.

1 Open the engine cover.

2 Loosen the hose clips

3 Move the hose clips away from the ﬁlter. Use a pair of ﬂat

pliers.

4 Pull off the ﬁlter from the hose ends.

5 Press the new ﬁlter into the ends of the hoses.

6 Push the hose clips back on the ﬁlter and tighten.

The main ﬁlter has a paper insert that is changed as follows.

1 Open the engine cover.

2 Unscrew the ﬁlter cover and remove the paper ﬁlter.

4 Wipe clean the interior of the air ﬁlter housing. If

necessary, the cleaning cloth should be moistened with white spirit or fuel. Water or compressed air should not be used.

5 Clean the ﬁlter by knocking it with care against a hard

surface. Do not use compressed air to clean the ﬁlter. Replace the air ﬁlter if it is still dirty.

6 Fit a new air ﬁlter cartridge with the hole inward and press

it into place.

7 Replace the air ﬁlter cover, ensure that the particle

collector is facing downwards.
