INSTRUCTION

Dear customer

Thank you for choosing a Husqvarna Rider. Husqvarna Riders are built to a unique design with a frontmounted cutting unit and a patented rear-wheel steering system. Riders are designed for maximum efficiency even in small or confined areas. The closely grouped controls and pedal-operated hydrostatic transmission also contribute to the performance of this machine.

We hope you will find this operator’s manual very useful. By following its instructions (on operation, service, maintenance, etc.) you will significantly extend the life of the machine and even its second-hand value.

When you sell your Rider, make sure you pass on the operator’s manual to the new owner. The last chapter in the operator’s manual consists of a Service Journal. Make sure that all service work and repairs are recorded. A well-documented service history reduces the costs of seasonal maintenance and influences the second-hand value of the machine. Collected controls and a hydrostatic transmission controlled by pedals also contribute to the machine’s performance.

Driving and transport on public roads

Check the relevant road traffic regulations before driving the machine on a public road. If transporting the machine on another vehicle always use approved securing devices and make sure that the machine is securely held.

Towing

Your machine is equipped with a hydrostatic transmission and, if necessary, you should only tow the machine over short distances and at a low speed, otherwise there is a risk of damaging the transmission.

Intended use

This machine is designed solely for cutting grass on conventional lawns and other cleared and leveled ground without obstacles, as rocks, stumps etc., and, in conjunction with accessories supplied by the manufacturer even for other special tasks for which instructions are delivered with the accessory. Use in any other way is considered as contrary to the intended use. Compliance with and strict adherence to the conditions of operation, service and repair as specified by the manufacturer also constitute essential elements of the intended use.

This machine should be operated, serviced and repaired only by persons who are familiar with its particular characteristics and who are acquainted with the relevant safety procedures.

Accident prevention regulations, all other generally recognised regulations on safety and occupational medicine, and all road traffic regulations must be observed at all times.

Any arbitrary modifications carried out to this machine may relieve the manufacturer of liability for any resulting damage or injury.

SAFETY INSTRUCTIONS

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.

Proceed as follows:

• Remove obstacles such as stones, branches, etc.

• Mow upwards and downwards, not sideways.

• Do not use the machine on ground that slopes

more than 15°.

• Avoid starting or stopping on a slope. If the tyres start to slip, stop the blades and drive slowly down the slope.

• Always drive smoothly and slowly on slopes.

• Do not make any sudden changes in speed or

direction.

Mow upwards and downwards on slopes, not sideways.

• Avoid unnecessary turns on slopes, if necessary, turn slowly and gradually downwards if possible.

• Watch out for and avoid driving over furrows, holes and bumps. It is easier for the machine to overturn on uneven ground. Tall grass can hide obstacles.

• Drive slowly. Do not turn the wheel sharply. The machine engine-brakes even better in low gear.

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

• Do not mow too close to edges, ditches or banks. The machine can suddenly overturn if one wheel comes over the edge of a steep slope or a ditch, or if an edge gives way.

• Do not mow wet grass. It is slippery, and tyres can lose their grip so that the machine skids.

• Do not try to stabilize the machine by putting your foot on the ground.

• When cleaning the chassis the machine must never be driven close to an edge or ditch.

Be especially careful when driving on slopes.

• Follow the manufacturer’s recommendations regarding wheel weights or counterbalance weights to increase stability.

SAFETY INSTRUCTIONS

Children

• Serious accidents may occur if you fail to be on

your guard for children in the vicinity of the machine. Children are often attracted to the machine and mowing. Never assume that children will remain where you last saw them.

• Keep children away from the area to be mowed and under close supervision by another adult.

• Keep an eye out and shut off the machine if children enter the work area.

• Before and during reversing procedures, look behind you and down for small children.

• Never allow children to ride along. They can fall off and seriously injure themselves or be in the way for safe manoeuvring of the machine.

• Never allow children to operate the machine.

• Be particularly careful near corners, bushes,

trees or other objects that block your view.

Maintenance

• Stop the engine. Prevent starting by removing

the ignition cable from the spark plug or remove the ignition key before making any adjustments or carrying out maintenance.

• Never fill the fuel tank indoors.

• Petrol and petrol fumes are poisonous and

extremely flammable. Be especially careful when handling petrol, as carelessness can result in personal injury or fire.

• Only store fuel in containers approved for the purpose.

• Never remove the fuel cap and fill the petrol tank while the engine is running.

• Allow the engine to cool before refuelling. Do not smoke. Do not fill petrol in the vicinity of sparks or naked flames.

Never allow children to operate the machine.

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

• Electrical shocks can cause injuries. Do not touch cables when the engine is running. Do not test the ignition system with your fingers.

8 – English

Never fill the fuel tank indoors.

SAFETY INSTRUCTIONS

• If leaks arise in the fuel system, the engine must

not be started until the problem has been resolved.

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

• 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.

• Avoid overfilling. If you spill petrol on the machine, wipe up the spill and wait until it has evaporated before starting the engine. If you spill petrol on your clothing, change your clothing.

• Allow the machine to cool before performing any actions in the engine compartment.

• Be especially careful when handling battery acid. Acid on the skin can cause serious corrosive injuries. In the event of spillage on the skin wash immediately with water.

• Acid in the eyes can cause blindness, contact a doctor immediately.

• Take care with battery maintenance. Explosive gases form in the battery. Never perform maintenance on the battery while smoking or in the vicinity of open flames or sparks. This can cause the battery to explode and cause serious injuries.

WARNING! The engine and the exhaust system become very hot during operation. Risk of burn injuries if touched.

WARNING! The battery contains lead and lead pollutants, chemicals that are considered to cause cancer, birth defects or other reproductive impairment. Wash your hands after touching the battery.

• Make sure all nuts and bolts are tightened

correctly and that the equipment is in good condition.

• Do not modify safety equipment. Check regularly to be sure it works properly. The machine must not be driven if protective plates, protective covers, safety switches or other protective devices are not fitted or are defective.

• Do not change the setting of governors and avoid running the engine at excessively high revs. If you run too fast, you risk damaging the machine components.

• Observe the risk of injury caused by moving or hot parts if the engine is started with the engine cover open or protective cowlings removed.

Do not smoke when carrying out maintenance.

DRIVING

MAX 15

WARNING! Never drive the machine on ground at an angle of more than 15°. Mow slopes upwards and downwards, never across. Avoid sudden changes in direction.

Cutting tips

• Localise and mark stones and other fixed

objects to avoid collision.

• Start with a high cutting height and reduce

down until the required mowing results are obtained.

• The mowing results are best with a high engine

speed (fast rotating blades) and low driving speed (slow moving machine). If the grass is not too high and thick, the driving speed can be increased without noticeably depreciating the mowing result.

WARNING! Clear the lawn from stones and other objects which can be thrown out by the blades.

• 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.

• Avoid mowing a wet lawn. The mowing results

are inferior since the wheels sink down into the soft lawn.

• Hose down the cutting unit with water

underneath each time it is used. Put the cutting unit in the service position first.

• If you use the BioClip unit it is important to

mow the grass regularly.

• It is important to mow frequently when mowing

with the mulching function.

LUBRICATION

General

Remove the ignition key to prevent accidental movement during lubrication.

If lubricating with an oil can, fill the can with engine oil.

If lubricating with grease, use grease 503 98 96-01 or a similar chassis grease or bearing grease with good corrosion resistance, unless otherwise specified.

If the Rider is used daily it should be lubricated twice a week.

Wipe off excess lubricant after lubrication.

It is important that lubricant does not get onto the drive surfaces of the belts or pulleys. If this happens, try to clean it off with white spirit. If the belt continues to slip it must be replaced. Do not use petrol or other petroleum products to clean V-belts.

Lubricating wires

Lubricate both ends of the wires, moving the controls through their full travel range while doing so. Refit the rubber protectors over the wires after lubrication. Wires with a casing will seize up unless lubricated regularly. If this happens it can lead to operating problems such as uncontrolled braking.

If a wire does seize up, remove it and hang it up vertically. Lubricate with light engine oil until the oil starts to drip from the lower end. Useful hint: Fill a small plastic bag with oil, tape it tightly around the wire casing and hang the wire vertically from the bag overnight. If this does not free up the wire then it must be replaced.

Winter storage

STORAGE

At the end of the season the machine should immediately be put in order for storage, also if it is going to stand idle for more than 30 days. Fuel which is left to stand for long periods (30 days or more) can leave tacky deposits which can block the carburettor and interfere with the engine.

Fuel stabiliser is an acceptable alternative to avoid tacky deposits during storage. If alkylate petrol (Aspen) is used stabiliser is not necessary since this fuel is stable. However, one should avoid changing from standard to alkylate petrol since sensitive rubber parts can harden. 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 so that it will reach the carburettor. Do not empty the fuel tank and carburettor if stabiliser has been added.

WARNING! Never place an engine with fuel in the tank indoors or in poorly ventilated areas where petrol fumes can come into contact with naked flames, sparks or pilot flames in boilers, hot water heaters, or drying cabinets, etc. It is highly inflammable and negligent usage can cause severe person injury and material damage. Drain off the fuel in an approved container outdoors and well clear of naked flames. Never use petrol for cleaning purposes. Use degreasing agents and hot water instead.

To put the machine in order for storage follow these instructions:

1. Carefully clean the machine, especially under the cutting unit. Touch-up paint damage to avoid rust.

2. Inspect the machine for worn or damaged parts and tighten loose screws and nuts.

3. Change the oil, and take care of the waste oil.

4. Empty the fuel tank. Start the engine and run it until the carburettor is emptied of fuel.

5. Remove the plugs and pour in a tablespoon of engine oil in each cylinder. Pull round the engine to distribute the oil and screw the plugs back on.

6. Grease all grease nipples, joints and axles.

7. Remove the battery. Clean it, charge it, and store it in a cool place.

8. Store the machine in a clean and dry place and cover it over for extra protection.

Cover

There is a cover to protect your machine during storage or transport. Contact your dealer for a demonstration.

Service

When ordering spare parts state the purchase year, model, type, and serial number.

Always use genuine parts.

Annual inspection or trimming by an authorised service workshop is a good way of getting the best out of your machine the next season.
