Cutting Unit
Depth Lever
Use the depth lever to raise and lower the blades
between working and transport position. The depth
lever has a lock-out bolt that should be left in until the
blades wear down. Then move the bolt to a lower hole
to allow the blades to penetrate the soil.
•
Flail Blades or Spring Tines Set blade or tine
depth so that the blades or tines just touch on a
flat surface such as a sidewalk or driveway.
•
Delta Blades Set blades to penetrate the soil to
a depth of 1/8" to ¼" with a maximum penetration
of ½". Check seed bag for the manufacture’s
recommended depth of application
•
Lawns with deep thatch exceeding ¾" may be
best dethatched in two treatments (spring and
fall) to avoid major shock to an older lawn.
Clutch
The clutch tightens the drive belt and engages the
drive for the blades. When the clutch lever is pressed
against the handle, the blades begin to rotate. Hold
the clutch tightly when working so the belt does not
slip.

CoNTRoLS
Blade versatility
Flail Blades
Thatch is the dense layer of clippings, roots and
stems that forms between the soil and the base of
the grass. As thatch builds up, it prevents water,
air and fertilizer from being absorbed into the soil.
This causes shallow root development leading to
vulnerability to drought and frost. Excessive thatch
also creates an ideal environment for insects and lawn
diseases. Power-raking with flail blades removes this
thatch layer and restores your lawn to good health.
Flail blades offer the most aggressive dethatching of
all the blades offered.
Delta Blades
Delta blades were created primarily for overseeding
existing lawn. They effectively incorporate grass
seed into the soil. This is an easy, reliable method for
rejuvenating poor lawns. The delta blade is also useful
as a vertical mower for cutting running stem grasses
and opening up the soil to oxygen, water, nutrients
and other chemicals. Delta blades are also beneficial
on slopes, terraces and in high clay content soils
where water runoff is a problem. The blades should
be set to penetrate the soil to a depth of 1/8" to ¼" with
a maximum penetration of ½".
Check your seed bag for the manufacture’s
recommended depth of application.
Spring Tines
Ideal for the established lawn that is not in need of a
complete renovation but requires dethatching (dry-
spots, fungus, etc.). Spring tines are designed to
pluck dead grass and thatch out of the lawn without
tearing or damaging existing root structure. With the
flexible tines, the lawn is combed only 0.5 cm into the
soil, so it cannot penetrate the root structure. Spring
tines provide less aggressive dethatching than flail
blades. NOTE: Do not use spring tines with bagger
attachment.

Flail Blades
Wear/Rotation/Replacing
After you have used your dethatcher for some time,
the blades will begin to wear on the striking edge.
When this happens, their dethatching performance will
diminish. A new combing edge may be obtained by
rotating the entire rotor shaft assembly laterally (end to
end). This procedure can be repeated until the blades
reach their wear limit; see illustration.

MAINTENANCE
Two Minute Rule
The machine may be tipped forward to facilitate
access for cleaning or service, but no longer than 2
minutes.
If the machine is held in this position for too long, the
engine can be damaged by gasoline draining into the
crankcase. Should this happen, perform an extra oil
change on the engine. Remove the spark plug and
turn the engine over a few revolutions with the starter
handle before starting the engine again.
Cleaning
8060-017
Regular cleaning and washing will increase the
machine’s lifespan. Make it a habit to clean the
machine directly after use, before the dirt sticks.
Check before rinsing that the fuel tank lid is properly
in place to avoid getting water in the tank.
Use caution when using high-pressure spray because
warning decals, instruction signs and the engine can
be damaged. Do not exceed 70 bar/1000 PSI water
pressure when cleaning.
Lubricate the machine after cleaning. This is
particularly important if the machine is to be stored.

LUBRICATIoN
Stop the engine and remove the ignition cable before
attempting to lubricate the machine.
Lubrication Schedule
1. Check engine oil daily, change every six months
or 100 hours.
2. Check and lubricate wheel bearings once a
month.
3. Lubricate folding handle points once a week.
4. Lubricate main shaft bearings once a week or
every 40 hours.
Wipe away excessive grease after lubrication. It is
important to avoid getting lubricant on the belt 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, it must be replaced.

SToRAGE
Winter Storage
At the end of the season, the machine should be
readied for storage (or if it will not be in use for longer
than 30 days). Fuel allowed to stand for long periods
of time (30 days or more) can leave sticky residues
that can plug the carburetor and disrupt engine
function.
Fuel stabilizers are an acceptable option to reducing
sticky residues during storage. If alkylate gasoline
(Aspen) is used, stabilizers are unnecessary because
this fuel is stable. However, you should avoid
switching between regular and alkylate gasoline
as sensitive rubber components can harden. Add
stabilizer to the fuel in the tank or in the storage
container. Always use the mixing ratios specified by
the manufacturer of the stabilizer. Run the engine for
at least 10 minutes after adding the stabilizer so that
it reaches the carburetor. Do not empty the fuel tank
and the carburetor if you have added stabilizer.
8011-130
Fuel tank plug and filter
5. Close the fuel valve.
6. Remove the spark plug and pour about a
tablespoon of engine oil in the cylinder. Turn over
the engine so that the oil is evenly distributed and
then refit the spark plug.
WARNING!
Never store an engine with fuel in the
tank indoors or in poorly ventilated
spaces where fuel vapor can come in
contact with open flame, sparks or a
pilot light such as in a boiler, hot water
tank, clothing 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 flame.
Never use gasoline for cleaning. Use a
degreaser and warm water instead.
7. Lubricate all grease nipples, joints and shafts as
described in the chapter “Lubrication/Lubrication
Schedule”.
8. Store the machine in a clean, dry place and cover
for extra protection.
Service
When ordering spare parts, please specify the
purchase year, model, type, and serial number.
Always use genuine Husqvarna spare parts.
An annual check-up at an authorized service
workshop is a good way to ensure that your machine
performs its best the following season.
To ready the machine for storage, follow these steps:
1. Clean the machine carefully, particularly the
chassis and working equipment. Mend damage to
the paint to prevent rust.
2. Inspect the machine 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. open the fuel valve. Empty the fuel tank and the
carburetor.
