Work safety
WARNING: Read the warning instructions that follow before you use the product.
· Use this product to cut grass lawns only. It is not permitted to use it for
other tasks.
· Use personal protective equipment. Refer to Personal protective equipment on
page 10.
· Make sure that you know how to stop the engine quickly in an emergency.
· Never start the engine in a closed space or near flammable material. The
exhaust fumes from the engine are hot and can contain sparks which can start a
fire.
· Do not operate the product unless the blade and all covers are attached
correctly. An incorrectly attached blade can come loose and cause personal
injury.
· Make sure that the blade does not hit objects such as stones and roots. This
can do damage to the blade and bend the engine shaft. A bent axle causes heavy
vibration and a very high risk that the blade becomes loose.
· If the blade hits an object or if vibrations occur, stop the product
immediately. Disconnect the ignition cable from the spark plug. Examine the
product for damages. Repair damages or let an authorised service agent do the
repair.
· Never attach the engine brake handle permanently to the handle when the
engine is started.
· Put the product on a stable, flat surface and start it. Make sure that the
blade does not hit the ground or other objects.
· Always stay behind the product when you operate it.
· Let all the wheels stay on the ground and keep 2 hands on the handle when
you operate the product. Keep your hands and feet away from the rotating
blades.
· Do not tilt the product when the engine is started.
· Be careful when you pull the product rearward.
· Never lift up the product when the engine is started. If you must lift the
product, first stop the engine and disconnect the ignition cable from the
spark plug.
· Do not walk rearward when you operate the product.
· Stop the engine when you move across areas without grass, for example paths
made of gravel, stone and asphalt.
· Do not run with the product when the engine is started. Always walk when you
operate the product.
· Stop the engine before you change the cutting height. Never make adjustments
with the engine started.
· Never let the product stay out of view with the engine started. Stop the
engine and make sure that the cutting equipment does not rotate.
· Before you do an adjustment, inspection, replacement or removal of blockage,
stop the product and let the blades stop fully. Blades that rotate can cause
injury. Do not touch blades while they rotate.
Safety instructions for operation
Personal protective equipment
WARNING: Read the warning instructions that follow before you use the product.
· Personal protective equipment cannot fully prevent injury but it decreases
the degree of injury if an accident does occur. Let your dealer help you
select the right equipment.
· Use hearing protection if the noise level is higher than 85 dB.
· Use heavy-duty slip-resistant boots or shoes. Do not use open shoes or go
with bare feet.
· Use heavy, long pants. · Use protective gloves when necessary, for example
when you attach, examine or clean the cutting equipment.
Safety devices on the product
WARNING: Read the warning instructions that follow before you use the product.
· Do not use a product with defective safety devices. · Do a check of the
safety devices regularly. If the
safety devices are defective, speak to your Husqvarna service agent.
To do a check of the cutting cover
The cutting cover decreases vibrations in the product and decreases the risk
of injury from the blade.
· Examine the cutting cover to make sure that there are no damages such as
cracks.
To do a check of the engine brake handle
The engine brake handle stops the engine. When the engine brake handle is
released, the engine stops.
· Start the engine and then release the engine brake handle. If the engine
does not stop in 3 seconds, let an approved Husqvarna service agent adjust the
engine brake. (Fig. 19)
To do a check of the rear deflector
The rear deflector decreases the risk that objects eject in the direction of
the operator.
· Make sure that the rear deflector is not damaged. (Fig. 20)
10
1242 – 003 – 01.11.2019
· Make sure that the springs that close the rear deflector are not broken.
· Replace broken springs and damaged parts. · Make sure that the rear
deflector can move smoothly
on the hinges.
Muffler
The muffler keeps the noise levels to a minimum and sends the exhaust fumes
away from the operator.
Do not use the product if the muffler is missing or defective. A defective
muffler increases the noise level and the risk of fire.
WARNING: The muffler becomes very hot during and after use and when the engine
operates at idle speed. Be careful near flammable materials and/or fumes to
prevent fire.
To do a check of the muffler
· Examine the muffler regularly to make sure that it is attached correctly and
not damaged.
To do a check of the oil level
CAUTION: A too low oil level can do damage to the engine. Do a check of the
oil level before you start the product.
1. Put the product on level ground. 2. Remove the oil tank cap with the
attached dipstick. 3. Clean the oil from the dipstick. 4. Put the dipstick
fully into the oil tank to give a correct
picture of the oil level. 5. Remove the dipstick. 6. Examine the oil level on
the dipstick. 7. If the oil level is low, fill with engine oil and do a
check of the oil level again.
Vibration safety
This product is for occasional operation only. Continuous or regular operation
of the product can cause “white finger” or equivalent medical problems from
vibrations. Examine the condition of your hands and fingers if you operate the
product continuously or regularly. If your hands or fingers have
discoloration, have pain, tingle, or are numb, stop work and speak to a
physician immediately.

To get a good result
· Always use a sharp blade. A blunt blade gives an irregular result and the
cut surface of the grass becomes yellow. A sharp blade also uses less energy
than a blunt blade.
· Do not cut more than of the length of the grass. Cut first with the cutting
height set high. Examine the result and lower the cutting height to an
applicable level. If the grass is very long, drive slowly and cut 2 times if
necessary.
· Cut in different directions each time to prevent stripes in the lawn.

and put the wire where it cannot touch the spark plug.
6. Pull the blade around by hand and make sure it rotates freely.
To replace the blade
1. Lock the blade with a block of wood. (Fig. 45) 2. Remove the blade bolt.
3. Remove the blade. 4. Examine the blade support and blade bolt to see if
there are damages. 5. Examine the engine shaft to make sure that it is not
bent. 6. When you attach the new blade, point the angled

1 The power rating of the engine indicated is the average net output (at
specified rpm) of a typical production engine for the engine model measured to
SAE standard J1349/ISO1585. Mass production engines may differ from this
value. Actual power output for the engine installed on the final product will
depend on the operating speed, environmental conditions and other values.
2 Use engine oil of quality SJ or higher. See the viscosity chart in the
engine manufacturer’s manual and select the best viscosity based on the
expected outside temperature.
3 Noise emissions in the environment measured as sound power (LWA) in
conformity with EC directive 2000/14/EC. Reported data for noise emissions in
the enviroment has a typical statistical dispersion (standard deviation) of
0.54 dB (A).
4 Noise pressure level according to ISO 5395. Reported data for noise pressure
level has a typical statistical dispersion (standard deviation) of 3.0 dB (A).
