1• YOUR SAFETY AND THAT OF OTHERS
USER RESPONSIBILITY
BEFORE USING YOUR BRUSH-CUTTER
• Before using your brush-cutter, make sure that you are completely
familiar with the controls and operating instructions so that you are
able to stop the machine quickly.
•
Always clear the lawn of toys, stones, pieces of wood or metal, wire,
bones, plastic, branches and other debris liable to be thrown out by
the
brush-cutter . Low branches liable to cause injury to the user
should also be removed.
• Before using the machine, ensure that the cutting blade is in good
condition and tight and that the handlebar is locked.
• Loose clothing and short trousers should not be worn when using
the brush-cutter.
• Always wear stout and closed shoes. Never use the brush-cutter
barefoot or wearing sandals.
• Wear ear defenders.
YOUR SAFETY AND THAT OF OTHERS
• Always follow these instructions when using your brush-cutter.
• Children under the age of 16 years, and people not familiar with the
brush-cutter must not be allowed to use the machine.
• Never let a person who has not read the instruction booklet take
charge of the brush-cutter.
• WARNING : Prolonged exposure to noise can be dangerous to
health. The symptoms are progressive: tinnitus, temporary hearing
loss, then progressive deafness. Use personal protection against
noise. Limit the intensity and duration of exposure. Avoid mowing
close to other sources of sound. Allow for rest periods.
• WARNING : Excessive exposure to vibration can affect the cir-
culation or the nervous system. The symptoms appear mainly in the
ngers, the hands or the wrists. These symptoms may include loss
of sensation, pain, muscle weakness, change in colour of the skin,
disagreeable tingling... Consult a doctor in case of appearance of
symptoms that may be triggered by vibrations.
• Never drive your brush-cutter too close to embankments or ditches,
on soft ground, or where there is a risk of overturning.
• Never operate the machine when feeling tired or unwell.
• Never operate the machine after consuming alcohol or taking medi-
cine.
• The user is responsible for ensuring the safety of others within the
area where the brush-cutter is being used.
• Keep third parties out of the way whilst mowing to avoid injury to
others caused by flying stones and other objects.
• The user is responsible for ensuring the safety of others within
the area where the brush-cutter is being used. Do not start the
machine if there are any around you.
• Never remove warning labels or safety instructions.
• The machine must be equipped with its safety flaps.
• Before changing the cutting height adjustment, stop the engine or
the blade rotation.
• Never place hands or feet under the cutter housing.
• Keep your hands and your legs clear of rotating or moving parts.
Always keep clear of the ejection opening.
• The hydraulic transmission of your brush-cutter uses pressurized
oil. Never start the brush-cutter without the hydraulic transmission
cowling: pressurized hydraulic uid that could escape could have
sufcient force to penetrate the skin and cause serious injuries in
which case medical help would be needed right away.
• Protect the face and the eyes when mowing under trees.
• Avoid obstacles such as mole hills, concrete pedestals, tree stumps
and edging, which cannot be cut by the blade and which could
damage the cutting mechanism specially the blade.
• After striking a foreign object or if the machine starts to vibrate
abnormally stop the motor, disconnect the spark plug cover and ins-
pect the brush-cutter for any damage. Have any repairs made before
restarting and using the brush-cutter.
• The blade must be changed after any shock.
• Operate the brush-cutter only in broad daylight or with good arti-
cial lighting.
• Do not mow during thunderstorms.
• Whenever possible, do not mow wet grass.
• Respect the minimum safety distance given by the handlebars.
• When using the brush-cutter on slopes, it is necessary to be particu-
larly careful and to exercise a great deal of caution when changing
direction.
Never mow up or down the slope, always mow across.
•It should not be used on slopes that are too steep (max. 20°).

• Be very careful if you reverse the brush-cutter or pull it back to-
wards yourself.
• Do not change the motor speed regulation settings or use the motor
at too high a speed.
WARNING : never allow the engine to run in conned areas.
Exhaust gases contain carbon monoxide, which is odourless and can
kill.
• Never close the choke flap when the engine is running or when it is
hot.
• Never leave the engine running unsupervised (even if the ma-
chine model allows).
• Stop the engine for any maintenance on the brush-cutter.
• The drive and blade clutch levers never have to be locked in wor-
king position.
• If the brush-cutter
has to be lifted or transported, stop the engine
and remove the spark plug cap.
•
If you drive the brush-cutter out of the lawn, stop the engine or
the blade.
• By loading and unloading the machine it is recommended to use
ramps or to ask help for the loading operation.
• Be sure also to comply with any legal requirements relating to the
use of machines with thermal engines.
• These precautions are essential for your safety.
• The recommendations given are not exhaustive however. Use your
brush-cutter judiciously at all times.
MAINTENANCE AND STORAGE
• Always maintain the machine and accessories in perfect working
condition.
• Replace worn or damaged parts for greater safety.
• Cleaning or servicing the brush-cutter should not be started before
having stopped the engine and disconnected the spark plug.
• Always use petrol that you have bought recently.

6• PREPARATION AND GETTING STARTED
HANDLEBAR
POSITION OF USE (PICTURE 2)
• Operate the offset control on the right of the handlebar.
• Swivel the handlebar 180 ° to the rear.
• Release the offset command.
LATERAL RELEASE OF THE HANDLEBAR (PICTURE 3)
• Operate the offset control on the right of the handlebar.
• Swivel the handlebar to the left or right.
• Release the offset command.
HEIGHT ADJUSTMENT OF THE HANDLEBAR (PIC-
TURE 4)
• Unscrew the nut using 2 x 13 mm wrenches and remove the two
washers and the threaded rod-washer-nut assembly.
• Hold the handlebar at the top and position it at the desired height.
• Replace the threaded rod-washer-nut assembly, the two washers and
tighten the nut.
ENGINE PREPARATION
Your brush-cutter is delivered with oil in the crankcase.
However, check the level before use and top up if necessary.
Never run an engine without oil even for short periods of
time.
Use an excellent quality detergent oil in class “SJ” or higher and with
a viscosity of SAE 30, 10W30 or the oil recommended by Etesia (ref.
38383).
• Place the brush-cutter on a horizontal and unencumbered area.
• Unscrew the cap and take out the dipstick (a pictures 5 and 6).
• Slowly pour oil. The oil capacity is 0,65 l for the AK60 model and
1,1 l for the AH75 model.
• Insert the dipstick in the filler tube and bring the cap to bear without
screwing it down.
• Take off the gauge and check the oil level. The mark left on the
gauge must reach the FULL mark for the AK60 model and the
upper limit for the AH75 model (a pictures 5 and 6). Top up if
necessary.
• In case of excess, recover the overflow with a syringe.
• When the level is correct, firmly screw in the cap of the filling tube.
• Then fill the fuel tank with unleaded fuel (b pictures 5 and 6). Use
recently purchased fuel stored in a jerrycan specially reserved for
this purpose. Only buy the quantity of fuel you can use within 1
month. The tank capacity is 4 l for the AK60 model and 2,1 l for
the AH75 model. Avoid spilling petrol and overfilling the tank to
prevent overflowing: leave approximately 1,5 cm space under the
filler collar to allow the fuel to expand.
CAUTION! Petrol is highly inammable. Do not smoke
while lling with petrol. The tank should always be lled
with the engine switched off.
• Never remove the fuel tank cap while the engine is running.
• If petrol has been spread, do not try to start the motor. Take the
machine away from the spoiled area and make sure there is no form
of ignition as long as the petrol vapour is not dispersed.
• Put the fuel tank cap and the fuel can properly.
• Avoid fuel overow while lling the fuel tank. In spite of these pre-
cautions should it happen, please :
a) Clean, as good as you can, all the contaminated parts.
b) Don’t start the machine as long as you’re not sure that all the
spread fuel has been eliminated.
Never add oil to the petrol! Adding a fuel saver marketed
under number 09800 will keep your fuel good for up to 6
months.
STARTING AND STOPPING THE
ENGINE
Before use, always make a visual check to ensure that
the blade, attaching screws and coupling are not worn or
damaged. Also check that the handlebar is locked.
STARTING THE ENGINE
• Open the fuel tap (pictures 7 and 8).
• lace the throttle lever on position [
] (picture 9) (the choke valve
will shut automatically).
• Make sure that the blade brake clutch and drive control levers are
not operated.
• Stand on the right of the handlebar, behind the brush-cutter.
• Slowly pull the starter unit handle until you feel the compression.
• Return to rst position before pulling vigorously to start the engine.
Hold on and follow the starter handle back to rst position.
• When the engine has started, put the throttle lever on [MAX] position
(2 picture 9).
STARTING AN ENGINE WHICH HAS BEEN RUNNING
ALREADY
• Place the throttle in position [MAX] (picture 9) and start the motor.
Never leave the engine running in closed areas where carbon
monoxide, a dangerous substance, could build up.
The oil gauge has to be fully srewed when the engine is run-
ning.
Do not change the original settings of the engine
and do not let the engine race. In the event of
maladjustment, contact your ETESIA dealership.
STOPPING THE ENGINE
• Pull the throttle lever gently to [STOP] position (picture 9).
• Close the petrol tap (pictures 7 and 8).

15
CUTTING HEIGHT ADJUSTMENT
Proceed only after engine has been switched off.
• Push the handlebar downwards to reduce the control effort.
• Operate the cutting height adjustment control (a picture 10).
• Lower or mount the handlebar to the desired height (3 positions) (b
picture 10).
• Release the cutting height adjustment control.
STARTING AND STOPPING THE BLADE
BLADE BRAKE CLUTCH
• This safety device controls the blade rotation of your self-pro-
pelled brush-cutter. The machine drive can also be used apart
from blade rotation, specially when taking the machine outside
the cutting area.
USE
Before you engage the blade, make sure that the engine
is warm enough and that it’s running at the maximum run
(throttle control lever on [MAX] position).
• Stand behind the handlebar in working position and keep your feet
away from the cutting blade.
• Push the red safety button to the right and hold it (1 picture 11).
• Apply the blade clutch control lever to the handlebar (2 picture 11),
then release the safety button. The blade will remain engaged after
releasing the safety button as long as the clutch lever is held against
the handlebar.
Don’t engage the blade when it’s in contact with long uncut
grass as it could cause difculties to start.
BLADE STOP
• Release the blade clutch lever to stop blade rotation. The blade will
be automatically braked and stopped within 7 seconds.
PARKING BRAKE (A PICTURE 12)
This security feature locks the wheels so as to immobilise your brush-
cutter.
• To engage the parking brake, pull the brake lever towards the back of
the machine and release it from its lock.
• To release the parking brake, pull the brake lever back and engage it.
DRIVE SPEED ADJUSTMENT
The hydraulic transmission enables the drive to be adapted to all
cutting conditions through progressive speed variation controlled by
the control lever.
Opt for a slow speed (position 1) when the conditions of use are diffi-
cult (wet grass, high or too dense, uneven ground).
Select a superior position (position 2 or 3) for a high speed if
the conditions of use allow it: dry grass, neither too high nor too
dense, at ground or displacement of the brush-cutter with the blade
stopped.
It is the observation of your terrain that will guide you in choosing
the optimal speed of advancement.
SPEED ADJUSTMENT
• Move the selector lever located on the left of the dashboard (a picture
13) in the notched position corresponding to the selected speed range
(1, 2 or 3).
DRIVE CONTROL
To move
• Act on the control lever (b picture 13). The speed is at maximum
when the control lever is closed to the handlebar.
• To stop position, release the lever.
Go reverse
• To go into reverse, release the control lever. Pull the reverse lever
(c picture 13) backwards. The speed of recoil is maximum when the
speed selector is maintained in rear stop, it will be even more reduced
that the reverse command will be accompanied to the initial position.
• To stop the machine, release the reverse control lever.
Be particularly careful when you use the reverse gear: disen-
gage the blade, and do not let yourself be surprised by the
machine’s movement.
Disengagement of transmission
• Pull the by-pass control to [0] position (b picture 12).
• Do not forget to switch the control to position [1], to be able to use
the transmission drive again.
DIFFERENTIAL LOCK CONTROL
The differential can be locked to prevent the driving wheels from
spinning and gain driving force on sloping ground or wet grass.
•
Actuate the differential lock control lever (picture 14).
• Release the differential lock control lever to return to the active diffe-
rential conguration and gain in handling capability.
Pay special attention when changing direction when using
the differential lock.
BLOCKING THE IDLING WHEELS (AH75)
In order to guarantee a good trajectory in reverse, the rotation of the
idling wheels must be locked with the latch (picture 15).
CUTTING - PRECAUTIONS FOR USE
ON SLOPES
• Place the throttle control lever on [MAX] position.
• Engage the blade (double safety control).
• Engage the drive control lever.
Never touch the blade when it is rotating.

8• MAINTENANCE
• Before any maintenance and in particular if tilting the machine is
necessary, close the fuel cock, run the engine until all the fuel still
contained in the lines and the carburettor is exhausted and then dis-
connect the spark plug cap.
The best maintenance is above all the regular cleaning of your brush-
cutter after each use (frame, wheels, transmission system...).
CHECKING THE SAFETY DEVICES
• Regularly check that the safety flaps are in place and in good condi-
tion. Have it replaced if it shows any signs of wear or damage.
• Ensure you about the good functioning of the safety control, release
the blade clutch lever to check the stop of the blade in less than 7
seconds.
If you notice something not working properly, contact your
ETESIA dealer as soon a possible.
CLEANING OF THE CUTTING UNIT
(A PICTURE 16)
• In order to access the brush-cutter deck more easily, it is advisable
to put the machine on a lifting table. It is also possible to tilt the
front of the machine so that it is inclined by 20 ° by placing two
jack on either side of the deck.
• Clean the brush-cutter particularly the inside of the cutting deck.
Wear protective gloves and remove debris and remaining grass
using a scraper and a brush.
• Never use a high pressure washer on the transmission parts or
engine. Never use a hot water washer.
MAINTENANCE OF THE CUTTING UNIT
All shocks against obstacles, or abnormal wear, may cause unbalance
and deterioration of the bearings or indeed of the engine as a whole.
In such cases the warranty becomes invalid. Use a new blade rather
than risk damage to the motor due to excessive unbalance of a poor
blade.
Whenever you need to work on the cutting system, first stop the
engine and remove the key from the ignition. Wear working gloves to
protect your hands.
Shear bolts provide a connection between the body of the blade and
the blade coupling. In the event of violent impact, the instant shearing
of these screws protects the entire transmission system.
Every time before you use the ride-on brush-cutter, check the condi-
tion of the blade (for any damage and wear).
If a blade has become blunt or is twisted, this will affect the standard
of cutting.
A damaged blade could be particularly dangerous if a piece comes
away and is ejected by the cutting system.
Replace immediately any worn or damaged blades.
The flails are reversible: after the cutting edge becomes worn, they
can be turned around.
Also check that the blade coupling is in perfect condition and that the
blade ends turn in the same plane.
If any damage is observed on a blade a more thorough examination
of the other components will be necessary, for instance the cutting
housing, blade coupling, shear bolts, blade bearing and belt.
If you do not know how to do it or you do not have the right tools,
contact your ETESIA dealer.
REPLACING THE SHEAR BOLTS
• You can purchase a set of 8 shear screws and nuts ref. 37762.
• Tighten the shear screws to a torque load of 10 Nm.
If you do not know how to do it or you do not have the right tools,
contact your ETESIA dealer.
REPLACEMENT OF BLADE BODY (PICTURES 16
AND 17)
• In order to access the brush-cutter deck more easily, it is advisable
to put the machine on a lifting table. It is also possible to tilt the
front of the machine so that it is inclined by 20 ° by placing two
jack on either side of the deck (a picture 16).
• Lock the blade by placing a wooden wedge between it and the cut-
ting housing (b picture 16) then detach the central screw with a 17
mm wrench.
• Before reassembling the blade coupling, grease the shaft and check
the condition of the lock washer (ref. 37665), on coupling (ref.
37669), and key (ref. 20602).
• Tighten the blade screw to 50 Nm.
REPLACING THE FLAILS
• Use spare part MC85 and assemble according to the exploded view
of picture 18.
REGULAR ENGINE MAINTENANCE
OILING (PICTURES 5 AND 6)
•Check the engine oil level regularly : every day before starting the
machine.
• Place the brush-cutter on a horizontal and unencumbered area.
• Clean carefully around the filler neck and take out the dipstick.
• Wipe the dipstick on a clean cloth, put it back into the filler neck
without screwing the plug back in.
• Remove the dipstick once more to check the oil level : the mark left
on the gauge must reach the FULL mark for the AK60 model and
the upper limit for the AH75 model.
• Top up if necessary.
7• OPERATING INSTRUCTIONS
Take special care when changing direction on slopes. Never
mow up or down the slope, always mow across (picture 1).
Always keep a safe distance away from the brush-cutter cutting
deck.
Stop the engine and disconnect the spark plug before
removing any jams, or clear the cutting deck volute .
The various safety flaps are there to protect you against pro-
jectiles. Do not use the machine if these protectors are da-
maged or missing. Do not under any circumstances remove
them.
• If you can not stop the engine with the main control, turn off the
petrol cock (this will stop the engine within 3 minutes).

17
• Do not fill the oil sump past the [FULL] (AK60) or the upper
(AH75) mark on the dipstick.
• Screw the plug of the filler neck up tightly before starting the
engine.
OIL CHANGE
• Before any maintenance operation and to avoid any risk of the
brush-cutter starting accidentally, disconnect the spark plug.
• The rst emptying has to be done after the rst 15 working hours.
These hours have to be considered like a burn in period during
which you have to run the engine carefully.
• Changing the oil has to be done every 50 hours or once a year for
the model AK60 or every 100 hours (6 months) for the model AH75.
Draining the engine outside.
Drain the oil out when the engine is still warm : the oil will
run out more easily than it would if it were cold.
OIL CHANGE METHOD
Be careful with used hot oil. Remove the used oil and dispose
of at authorised disposal centre.
AK60 (PICTURE 19)
• Remove the drain plug (A) on the side of the engine.
• Drain the oil into a suitable container (B).
• Replace the drain plug.
AH75 (PICTURE 20)
• Place a container under the engine to collect used oil. Remove the
dipstick (a), the oil drain plug and the washer (b).
• Drain the oil completely.
• Replace the drain plug with a new washer. Tighten thoroughly.
AK60 - AH75
• Clean carefully around the filler neck and the dipstick.
• Pour the new oil carefully into the filler hole.
• Check the oil level.
• Top up if necessary.
COOLING SYSTEM, CARBURETTOR
• Regularly remove grass cuttings around the starter unit.
• Clear the cooling ns and around the engine of any accumulations
of grass. This way you will ensure that your engine is constantly
and efficiently kept cool.
• The carburettor linkage must be kept perfectly clean.
SPARK PLUG
To ensure proper engine operation, the spark plug should not show
any deposit, and it must have a proper electrode gap. A dirty spark
plug can lead to difficulty with starting and a constant loss of engine
power.
Do not hesitate to change a worn spark plug when necessary.
Use only ETESIA original spark plugs (03861).
AK60 (PICTURE 21) / AH75 (PICTURE 22)
• Remove the spark plug with a 13/16 inch spark plug wrench.
• Check the spark plug. Replace it if it is damaged or dirty, if its sea-
ling washer is in poor condition or if its electrode is worn out.
• Clean the electrodes every 50 hours or at least once a year for the
model AK60 or every 100 hours or 6 months for the model AH75.
• Measure the electrode gap with a feeler gauge. If necessary, correct
it by bending the side electrode (a picture 23). The distance must be
0.7 - 0.8 mm.
• Screw the spark plug by hand
• After putting the spark plug in place, tighten it with a spark plug
wrench 13/16 to compress the washer (23 Nm).
• When installing a new spark plug, tighten 1/2 turns after it touches
the washer to compress it. To install a used spark plug, tighten 1/8 -
1/4 turns after it touches the washer to compress it.
• Replace the spark plug every 100 hours of operation for the model
AK60 or every 300 hours for the model AH75.
AIR FILTER
If the air filter is dirty, the flow to the carburettor will be restricted.
To prevent any carburettor malfunction, regularly maintain the air
filter.
Running the engine with loose or damaged air filter components may
cause premature wear or engine failure.
• It is inevitable that impurities will get into the air lter. That is why
it is essential that you regularly remove the cartridge of the air lter
for cleaning (every 25 hours for the AK60 model or every 50 hours
(3 months) for the AH75 model or more often in dusty conditions).
AK60 (PICTURE 24)
• Unscrew the cover (A) of the air lter and remove it.
• Carefully remove all the paper cartridge with the prelter (B).
• Clean the inside of the lid (A) and the base (C) of the air lter.
• Remove the foam prelter (B1) from the paper cartridge (B2).
• Clean the paper cartridge (B2) by gently tapping it on a at surface.
Do not use solvent and do not use compressed air, as they could
damage the cartridge.
• Do not oil the cartridge. Replace it if worn or dirty, every 300 hours
or at least once a year.
• Wash the foam pre-filter (B1) in soapy water and dry thoroughly.
Oil the pre-filter element and squeeze it in the hand to distribute the
oil well and remove any excess. Reinstall it on the paper cartridge.
• Reinstall the new or cleaned cartridge (B) on its base (C).
• Replace the cover (A) of the air lter and screw it in.
AH75 (PICTURE 25)
• Detach the wing nuts (a) and remove cover (b).
• Clean the cover carefully.
• Removed carefully the paper cartridge (c) and the pre-filter element
(d). Replace them as soon as they become damaged or too dirty.
8• MAINTENANCE

18
• Wash the pre-filter in soapy water and dry thoroughly.
• Oil the prefilter element and press it in your hands to spread out the
oil evenly and remove any excess.
• Clean the paper cartridge by tapping it gently on a flat surface in
order to drop the excess dirt or carefully send compressed air from
the inside to the outside of the filter. Never attempt to remove the
dirt with a brush; brushing will force dirt into the fibres. Replace
the element if excessively dirty or every 300 hours.
• Assemble the filter elements (d and c), reinstall cover (b) and screw
on the nuts (a).
HYDRAULIC TRANSMISSION
• To access the hydrostatic bridge, remove the rear cover (picture 26).
• Clean the hydrostatic gearbox cooling ns regularly and also check
that the fan is in good condition.
Check the hydraulic oil level when cold.
Before unscrewing the hydraulic oil cylinder (a picture 27), clean it
carefully and make sure that no impurities get into it.
Make sure that the oil level of the transmission is still correct. Top up
if necessary (picture 27). We recommend 10W40 oil cans ref. 38383
(2 liters).
An oil change (b picture 27) must be carried out by your ETESIA
dealer after 50 hours of operation, then every 200 hours.
CHANGING TYRES
• Where it is necessary to remove a wheel, this should be done on firm,
even ground.
• Do not attempt to carry out work on or under the mower if it has
been raised on temporary supports or without taking proper safety
precautions.
• If you do not possess appropriate tools or the knowledge needed to
carry out the work, contact your dealer.
• Remove the wheels in the following manner:
- Stop the engine.
- Apply the parking brake.
- Secure the vehicle using chocks.
- Remove the wheel hub.
- Unscrew the 3 screws with a at wrench of 10. Remove sidewards
the two securing rings.
- Place a jack under the rear part of the chassis on the side where the
wheel needs to be replaced and lift until this wheel does not touch
the ground anymore.
- Secure the machine by lying it on stable props. You can now remove
the wheel from the shaft.
• For remounting, follow the same instructions in the opposite way. Do
grease the wheel shaft.
WARNING ! Do not lose the O shape key which fits in the
wheel shaft.
• Check the screw tightness.
• Check the tyre pressure : 1 bar
DISPOSAL OF USED TYRES
It is forbidden to leave standing, to lay down or to burn tyres in nature.
Our dealer network has been informed about its obligation to take back,
free of charge, all used tyres from ETESIA brush-cutters.
STORAGE (PICTURE 28)
To reduce the space taken up by the brush-cutter during transport or
for storage purposes, the handlebar can be rapidly folded towards the
front by carrying out the following operations in this order :
• Operate the offset control (1) on the right of the handlebar.
• While keeping this control active, press the button (2) at the base of
the handlebar for 180 ° rotation to the left (3).
TRANSPORT (PICTURE 29)
If the machine has to be raised or transported, turn off the
motor. Allow it to cool for at least 15 minutes before loa-
ding the brush-cutter into a vehicle.
It is advisable to use a loading ramp to load and unload the
brush-cutter.
For any delivery on a trailer or in a van:
- Position the machine in the vehicle.
- Stop the engine.
- Engage parking brake.
- Close the petrol tap.
- Block the idle wheels (picture 15).
- Transporting your mower using straps (picture 29).
The brush-cutter must be kept horizontal to avoid oil or petrol overow.

9• LONG STOP - WINTER STORAGE
PREPARATION
• Start by cleaning carefully the brush-cutter particularly under the
cutting deck.
• To avoid sediment, completely empty the fuel from the tank and,
open the fuel tap and empty the fuel in the carburettor tank by uns-
crewing the emptying screw or by leaving the engine running until
it becomes empty.
The tank emptying has to be done outdoors.
Don’t smoke.
• Disconnect the spark top.
• Engine hot, empty the oil frame. Fill with new oil until you reach
the FULL mark for the AK60 model and the upper limit of the
gauge for the AH75 model.
• Proceed to cleaning the air lter.
• Remove the spark and oil the cylinder with a spoonful of oil. Pull
the starter several times to distribute the oil and protect the cylinder
and valves from corrosion.
• Put the spark plug back.
• To prevent rust from forming, close the engine valves by pulling
gently on the starter handle until you feel some compression.
• Before you put the machine back into place, cool the machine then
drive it into a dry place on a shelf or a sheet of metal.
To reduce the risk of re, store the machine in place free of
grass, leaves and grease and far from any ignition spark.
• Of course you may leave this seasonal maintenance work to your
ETESIA dealer if you wish. He will check that your brush-cutter is
in good condition...so that it starts first go the following spring.
TO PUT IT BACK TO SERVICE
• Proceed as follows :
- Unscrew the spark and clean it with fuel. Allow to dry without
replacing it.
- Pull energetically several times on the starter cord to eliminate
oil excess from the cylinder.
- Ret the spark plug.
- Check the oil level and tank with unleaded fuel.
- Open the petrol tap before starting the engine.
• This seasonal maintenance can of course be done by your ETESIA
dealer.
