INTRODUCTION

Introduction

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.

Personal protective equipment

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.

IMPORTANT INFORMATION

Do not drive down slopes with the unit raised.

Do as follows

• Remove obstacles such as stones, tree branches,

etc.

• Mow up and down, not side-to-side.

• Never drive the machine on terrain 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 evenly and slowly on slopes.

• Make no sudden changes in speed or direction.

• Avoid unnecessary turns on slopes, and if it proves

necessary, turn slowly and gradually downward, 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.

• Be extra cautious with any additional equipment,

which can alter the machine’s stability.

• Do not mow near verges, 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.

• Try not to stabilise the machine by putting a foot

on the ground.

• When cleaning the chassis, the machine may never

be driven near verges or ditches.

• Follow the manufacturer’s recommendations

regarding wheel weights or counterbalance weights to increase machine stability.

6003-004

Mow upwards and downwards on slopes, not sideways

8010-054

DRIVING

Mowing tips

WARNING!

Clear the lawn of stones and other objects that can be thrown out by the blades.

• Localise and mark rocks and other ﬁxed objects in

order to avoid collisions.

• Begin with a high cutting height and reduce it until

the desired mowing result is attained.

• The best mowing result will be obtained at a high

engine speed (the blades rotate rapidly) 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.

6007-212

Mowing patterns

WARNING!

Never drive the Rider on terrain that slopes more than 15°. Mow upwards and downwards on slopes, never sideways. Avoid sudden changes in direction.

• The ﬁnest lawns are obtained by mowing often.

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.

• Hose beneath the cutting unit with water after each

use. When cleaning, the cutting unit should be moved into the service position.

• It is important to mow frequently when mowing

with the mulching function.

Clutch control

The clutch control must be pulled out in order for the Rider to be moved when the engine is shut off.

6008-208

English-34

MAINTENANCE

Checking and adjusting the steering cables

The steering is governed by means of cables.

After a period of use these can become stretched, which means the steering setting may have changed.

Steering is checked and adjusted as follows:

1. Remove the frame plate by loosening the two

screws.

2. Ensure that the cables are properly situated under

the steering cable pulleys in the frame tunnel. Check the tension of the steering cables by squeezing the cables together (at the arrows). It should be possible to squeeze the cables so that the distance between them is half the size, without using too much force.

Change the cable if it has a damaged strand causing loose threads to protrude.

8009-340

3. If necessary, the cables can be stretched by ﬁrst

loosening the lock nut and then tightening the adjustment nut (one cable on each side of the machine).

Hold the cable with, for example, an adjustable wrench so that it does not twist. If the adjustment is only made on one side, the middle position of the steering will be affected.

Do not over tighten the cables; they should only be drawn in towards the steering collar.

Check the cable tension after you have made the adjustment as described in point 2.

6008-212

8009-341

English-35

MAINTENANCE

LUBRICATION

General

Remove the ignition key to prevent unintentional movements during lubrication.

When lubricating with an oil can, 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 spirit. If the belt continues to slip after cleaning with spirit, 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 bind if they are not lubricated regularly. If a cable binds, the unit may become difﬁcult to operate - it may be hard to get the differential lock out, for example.

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.

Accessories

Lubrication or other maintenance of optional equipment or accessories, see “Accessories” on page 16, is not described in this manual. This equipment too, naturally, requires maintenance. See the manuals for the respective accessories for instructions.

It’s good practice to make a note of maintenance or necessary actions preformed on this page.

STORAGE

Storage

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 stabilisers 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.

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 care. It is very ﬂammable and careless use can cause serious personal injury and property damage. 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.

To ready the Rider for storage, follow these steps:

1. Clean the Rider thoroughly, 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 screws 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.

English-73

STORAGE

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.

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 purchase year, model, type, and serial number of the Rider.

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.

3. Hydraulic oil ﬁlter

Keep the hydraulic system clean. Remember to:

• Thoroughly clean before the ﬁlling cap is opened or any connector is loosened.

• Use clean containers when ﬁlling the oil.

• Only use clean oil that has been stored in a sealed

container.

• Do not reuse drained oil.

• Change the oil and ﬁlter according to the intervals

speciﬁed in “Maintenance schedule” on page 29.

In order for a hydraulic system to function without problem, it must be free from foreign objects. When used, the system produces particles, which can cause both wear and abnormal function. In order to remove these particles, the system contains ﬁlters. The ﬁlters are sized so as to capture the produced particles, but if contaminants are introduced from outside the system, the ﬁlters can quickly become clogged and fail to function as intended. If there are contaminants in the system, further contamination will be produced in a self-propagating cycle. The result will be function disruptions and much work to clean the system.
