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. Remember to take along the operator’s manual when you take the Rider
to the workshop for servicing.
Travel 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
If your machine has a hydrostatic transmission you should only tow it very short distances at low speed if
absolutely necessary, otherwise the transmission may be damaged.
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

•Be careful when rounding a fixed object so that the
blades do not hit it. Never drive intentionally over a
foreign object.
•The machine is heavy and can cause very severe
crush injuries. Be extra careful when loading it on a
trailer or truck.
•Be careful when pulling a load or using heavy
equipment.
a. Only use approved tow hooks.
b. Limit the load to what you can manage safely .
c. Do not make sharp turns. Be careful when revers-
ing.
d. Use counterweights or wheel weights when
indicated in the instructions.
Driving on slopes
Driving on slopes is one of the situations where there is
the most serious risk that the driver can loose control or
that the machine tips over, which can cause severe
injuries or be fatal. All slopes require extra care. If you
cannot reverse up the slope or if you feel uncertain avoid
cutting it.
Do as follows:
•Remove obstacles such as stones and branches etc.
•Cut upwards and downwards, not sideways.
•Look out for and avoid driving over furrows, holes or
mounds. On uneven surfaces it is easier for the
machine to tip over. High grass can conceal obstacles.
•Drive slowly . Use small movement on the hydrostat
pedals.
•Follow the manufacturer’s recommendations on
wheel weights or counterweights to increase stability .
•Be extra careful with the grass collector or other
equipment which can alter the stability of the machine.
•Always drive smoothly and slowly on slopes. A void
sudden changes of speed or direction.
•Avoid starting or stopping on a slope. If the tyres
begin to skid switch off the blades and drive slowly
down the slope.
•Avoid unnecessary turns on slopes, and if turning is
necessary turn slowly and gradually , downwards if
possible.

The seat has a jointed attachment on the front edge
and can be tipped forward.
The seat can also be adjusted lengthways.
To adjust move the lever under the front edge of the
seat to the left, so that the seat can be moved
forward or backwards to the required position.
Fuelling
The engine runs on unleaded petrol with a
minimum octane rating of 87 (not mixed with oil).
We recommend the use of Aspen biodegradable
alkylate petrol. Refer to the “Technical data” for
information on methanol and ethanol fuels.
WARNING!
Petrol is highly inflammable.
Exercise care and refuel outdoors
(see safety instructions).

English – 15
DRIVING
Cutting tips
WARNING!
Clear the lawn from stones and
other objects which can be
thrown out by the blades.
•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 or the engine speed reduced without
noticeably affecting the mowing results.
•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. The cutting unit
should be raised into the service position when
cleaning.
•If you use the BioClip unit it is important to mow
the grass regularly.
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.
