Congratulations

Thank you for purchasing a Husqvarna Rider. Husqvarna Riders have been designed according to a unique

concept with a front mounted cutting unit and patented rear wheel steering. The Rider is built to give

maximum efficiency even in small and confined areas. Collected controls and a hydrostatic transmission

controlled by pedals also contribute to the machine’s performance.

This Operator’s Manual is a valuable document. Following the instructions (use, service, maintenance, etc.)

can considerably increase the life span of your machine and even increase its resale value.

When you sell your Rider, make sure to give the operator’s manual to the new owner.

The final chapter of this operator’s manual comprises a Service Journal. Ensure that service and repair

work is documented. A well-kept service journal reduces service costs for the season-based maintenance

and affects the machine’s resale value. Take the operator’s manual along when the Rider is left to the

workshop for service.

Driving and Transport on Public Roads

Check applicable road traffic regulations before driving and transport on public roads. You should always use

approved fasteners during transport and ensure that the machine is well secured.

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.

The power transmission must be disengaged when towing, see Clutch Control.

Use

This machine has been designed to mow grass on lawns and other open and level ground surfaces without

obstacles such as stones, tree stubs, etc., even when the machine is equipped with special accessories

provided by the manufacturer, for which the operating instructions are enclosed with the delivery. All other

types of use are incorrect. The manufacturer’s instructions with regard to driving, maintenance, and repair

must be followed precisely.

The machine may only be operated, maintained, and repaired by persons that are fully conversant with the

machine’s special characteristics and safety regulations.

Accident prevention regulations, other general safety regulations, occupational safety rules, and traffic

regulations must be observed.

Unauthorised modifications to the design of the machine may absolve the manufacturer from liability for any

resulting personal injury or property damage.

English – 7

8010-054

6003-004

Be extra cautious when driving on slopes

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.

•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 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 under the machine, it may never

be driven near verges or ditches.

•Follow the manufacturer’s recommendations

regarding wheel weights or counterbalance

weights to increase stability.

SAFETY INSTRUCTIONS

Mow upwards and downwards on slopes, not sideways.

Risk of sparking

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 stay put 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.

SAFETY INSTRUCTIONS

Never fill the fuel tank indoors

Maintenance

•Stopping the engine. Prevent the engine from

starting by removing the spark plug cables from

the spark plugs or by removing the ignition key

before making any adjustments or performing

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.

• 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.

• Sparking can occur when working with the

battery and the thick cables in the starter motor

circuit.

This can cause the battery to explode, fire or

eye injuries.

Sparking in the circuit can not occur once the

battery’s power connection cable (usually the

black negative cable) has been disconnected.

8010-057

Never allow children to operate the machine

English – 9

6003-009

- Wearing protective glasses.

- Make sure that the fuel cap is fitted and that no

flammable liquids are stored in an open container.

- Do not work on the starter motor circuit in the

vicinity of spilt fuel.

- Disconnect the battery’s power connection cable

(usually the black negative cable) first and

connect it last.

- Exercise care with tools so that short circuiting

does not occur.

- Do not short circuit across the starter relay’s

connections to run the starter motor.

•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 and

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.

•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.

SAFETY INSTRUCTIONS

Do not smoke when carrying out maintenance

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 you hands after

touching the battery.

upwards and downwards on

slopes, never sideways. Avoid

sudden directional changes.

6007-212

Mowing patterns

WARNING!

Clear the lawn of stones and other

objects that can be thrown out by

the blades.

Mowing Tips

•Find and mark out any stones and other fixed

objects to avoid colliding with them.

•Start with a high cutting height and reduce it

until the desired mowing result is obtained.

•The best mowing result is achieved with high

engine revs (the blades rotate quickly) and low

speed (the Rider moves slowly).

If the grass is not too long and thick the driving

speed can be increased without significantly

impairing the mowing result.

•The finest lawns are obtained if they are mown

frequently. Mowing will be more even and the

clippings will be more evenly distributed across

the area.

The overall mowing time will not be longer as

higher driving speeds can be selected without

impairing the mowing result.

•Avoid mowing wet lawns. The mowing result will

be poorer as the wheels will sink into the soft

lawn.

•Rinse off the underside of the cutting unit after

use with water, do not use a high pressure

washer. When cleaning, the cutting unit shall be

moved into the service position.

•It is important to mow frequently when mowing

with the mulching function.

General

Remove the ignition key to prevent unintentional movements during lubrication.

When lubricating with an oilcan, it ought to be filled with engine oil.

When lubricating with grease, unless otherwise stated, grease 503 98 96-01 or another chassis or ball

bearing grease offering good corrosion protection shall be used.

With daily use, the Rider should be lubricated twice weekly.

Wipe away excess grease after lubrication.

It is important to avoid getting lubricant on the belts or the drive surfaces on the belt pulleys. Should this

happen, attempt to clean them with spirits. If the belt continues to slip after cleaning with spirits, it must be

replaced. Petrol or other petroleum products must not be used to clean belts.

Lubricating the Cables

Grease both ends of the cables and move the controls to end stop positions when lubricating. Re-attach the

rubber covers on the cables after lubrication. Cables with sheaths will jam if they are not lubricated regularly.

Binding in a cable may cause malfunction such as partial braking.

If a cable binds, remove the cable and hang it vertically. Lubricate it with thin engine oil until the oil begins to

escape from the bottom. Tip: Fill a small plastic bag with oil and tape it so that it seals against the casing and

allow the cable to hang vertically from the bag overnight. If you do not succeed in lubricating the cable, it

must be replaced.

STORAGE

To ready the Rider for storage, follow these steps:

1. Clean the Rider carefully, especially under the

cutting unit. Touch up damaged paint to prevent

rust.

2. Inspect the Rider for worn or damaged parts

and tighten any nuts or bolts that may have

become loose.

3. Change the engine oil; dispose of properly.

4. Empty the fuel tank. Start the engine and let it

run so that even the petrol in the carburettor is

emptied.

5. Remove the spark plugs and pour about a

tablespoon of engine oil into each cylinder. Turn

over the engine so that the oil is evenly

distributed and then refit the spark plugs.

6. Lubricate all grease nipples, joints, and shafts.

7. Remove the battery. Clean, charge, and store

in a cool place.

8. Store the Rider in a clean, dry place and cover

it for extra protection.

Cover

There is a cover to protect your machine during

storage or transport. Contact your dealer for a

demonstration.

Service

Low season is the most suitable time to perform a

service or overhaul of the machine in order to ensure

high functional safety during the high season.

When ordering spare parts, please specify the

Rider’s year of purchase, model, type, and serial

number.

Always use genuine Husqvarna spare parts.

An annual check-up or trimming at an authorised

service representative is a good way to ensure that

your Rider performs at its best the following season.

WARNING!

Never store an engine 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.

Handle the fuel with caution. It is

very flammable and careless use

can cause serious damage to

person and property. Drain the

fuel into an approved container

outdoors and far away from open

flames.

Never use petrol for cleaning. Use

a degreasing agent and warm

water instead.

Winter Storage

At the end of the mowing season, the Rider should

be readied for storage, likewise if it will not be in

use for more than 30 days. Fuel allowed to stand

for long periods of time (30 days or more) can leave

sticky residues that can clog the carburettor and

disrupt engine function.

Fuel stabilizers are an acceptable option as regards

sticky residues during storage. If alkylate petrol is

used, stabilisers are unnecessary because this fuel

is stable. However, you should avoid switching

between standard and alkylate petrol as sensitive

rubber components can harden. Add stabiliser to

the fuel in the tank or in the storage container.

Always use the mixing ratios specified by the

manufacturer of the stabiliser. Run the engine for at

least 10 minutes after adding the stabiliser so that it

reaches the carburettor. Do not empty the fuel tank

and the carburettor if you have added stabiliser.
