SAFETY INSTRUCTIONS

Personal protective equipment
IMPORTANT INFORMATION
If used incorrectly or carelessly this machine can become a dangerous tool that can cause serious or fatal injury to the operator or others. It is extremely important that you read and underst­and the content of this manual.
When using the machine, personal protective equipment approved by the appropriate authorities must be used. Personal protective equipment does not eliminate the risk of accidents. However, it can reduce the effects of an injury in the event of an accident. Ask your dealer for help when choosing protective equipment.
WARNING!
!
GLOVES Gloves must be worn whenever required, for example when fitting, inspecting or cleaning cutting equipment.
EAR PROTECTION Ear protection offering sufficient dampening effect should be used.
EYE PROTECTION Blows from branches or objects thrown out by the cutting equipment can damage the eyes.
Remove your hearing protection as soon as you stop the engine, so that you can hear any noises or warning signals.
The machines safety equipment
This section describes the machines safety equipment, its function and how checks and maintenance are carried out to ensure that it operates correctly. (See the chapter “What is what“ to locate where this equipment is positioned on your machine.)
WARNING!
!
1. Throttle trigger lock
The throttle trigger lock is designed to prevent the throttle from accidentally being engaged. When the trigger lock (A) is pressed into the handle (= when you hold the handle) the throttle (B) is released. When the grip on the handle is released the throttle and the throttle trigger lock return to their original positions. This takes place via two independent return spring systems. This means that the throttle is automatically locked in its “idling“ position.
Never use a machine with defective safety equipment. Follow the control, maintenance and service instructions described in this section.
A
B
BOOTS Use anti-slip and stable boots.
CLOTHING Wear clothes made of a strong fabric and avoid loose clothing that can catch on shrubs and branches. Always wear heavy, long pants. Do not wear jewelry, short pants, sandals or go barefoot. Secure hair so it is above shoulder level.
FIRST AID KIT The operator must carry a first aid kit.
4 – English
2. Stop switch
The stop switch should be used to stop the engine.
SAFETY INSTRUCTIONS
3. Vibration damping system
Your machine is equipped with a vibration damping system, which is designed to give as vibration-free and comfortable use as possible.
The machine’s vibration damping system reduces the transfer of vibrations between the engine unit/ cutting equipment and the machine’s handle unit.
WARNING!
!
Over exposure to vibrations can result in blood-vessel or nerve injury to persons suffering with blood circulation problems. Seek medical attention if you experience physical symptoms that can be related to over exposure to vibrations. Examples of such symptoms are “numbness“, lack of feeling, “tickling“, “pricking“, “pain“ lack of or a reduction in normal strength, changes in the colour of the skin or its surfaces. These symptoms normally appear in the fingers, hands or wrists.
4. Muffler
The muffler is designed to give the lowest possible noise level and to direct the engine‘s exhaust fumes away from the operator. Muffler fitted with catalytic converter is also designed to reduce harmful exhaust components. In countries that have a warm and dry climate the risk of fire is obvious. We have therefore fitted certain mufflers with a spark arrest screen. Make sure that your muffler is fitted with this kind of screen. It is extremely important that the instructions for checking, maintaining and servicing the muffler are followed. (see the section “Control, maintenance
and service of the machine‘s safety equipment“).
WARNING!
!
!
Mufflers fitted with catalytic converters become extremely hot during use and after stopping. This also applies at idling speeds. Contact can result in burns to the skin. Be observant to the risk of fire!
WARNING! Bear in mind that exhaust fumes:
contain carbon monoxide, which can cause carbon monoxide poisoning. Therefore never start or run the machine indoors.
are hot and can contain sparks that can cause fires. Never start the machine indoors or close to inflammable material.

SAFETY INSTRUCTIONS
Inspecting, maintaining and servicing machine safety equipment
IMPORTANT INFORMATION
All service and repairs to the machine require special training.
This applies especially to the machines safety equipment. If the machine does not meet any of the controls listed below you should contact your service workshop.
The purchase of one of our products guarantees that professional repair and servicing will be carried out on it. If the point of purchase is not one of our servicing dealers, please ask for details of the closest service workshop.
1. Throttle trigger lock
Check that the throttle is locked in the “idling position when the throttle trigger lock is in its original position.
Press in the throttle trigger lock and make sure it returns to its original position when released.
Ensure that the throttle and throttle trigger lock move easily and that their return spring systems function.
See section Start. Start the machine and apply full throttle. Release the throttle and check that the cutting equipment stops and remains at a standstill. If the cutting equipment moves with the throttle in the idling position, then the carburettors idling setting must be checked. See chapter Maintenance.
3. Vibration damping system
Check the vibration damping element regularly for material cracks and distortion.
Check that the vibration damping element is undamaged and securely attached.
4. Muffler
1.Never use a machine that has a defective muffler.
2.Check regularly that the muffler is secure.
3.If your muffler is fitted with a spark arrest screen then it should be cleaned regularly. A blocked screen leads to the engine overheating with serious damage as a result. Never use a muffler with a defective spark arrest screen.
2. Stop switch

5. Cutting equipment
This section describes how through correct maintenance and through using the right type of cutting equipment you can:
Obtain maximum cutting capacity.
Increase the service life of the cutting equipment.
1 Check the cutting
equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced.
2 Only use cutting
equipment recommended by us! See the ”Technical data section.
3 Keep the chain cutting
teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.

safety equipment. The safety equipment should be maintained as described in this section. If your machine does not meet any of these controls you should contact your service workshop.
WARNING! Always stop the engine before carrying out any work on the cutting equipment. This will continue to move even after the throttle has been released. Make sure the cutting equipment has stopped completely and disconnect the HT lead from the spark plug before you start work on it.
Specification of blade and chain
When the cutting equipment supplied with your machine becomes worn or damaged, you will need to replace it. Use only the manufacturer approved bar and chain.
Guide bar
Length (inches/cm)
4 Maintain the correct
raker clearance! Follow our instructions and use the recommended raker gauge. Too large a clearance increases the risk of kickback.
5 Keep the chain properly
tesioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.
6 Keep cutting equipment
well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket.
Number of teeth on bar tip sprocket (T). Small number = small tip radius = low-kickback
Chain pitch (inches) The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.
Number of drive links The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket.
Bar groove width (inches/ mm) The groove in the bar must match the width of the chain drive links.

The risk of kickback is increased with a badly sharpened chain!
A.General information on sharpening cutting teeth
Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all, just wood powder.
A sharp chain eats its way through the wood and produces long, thick cuttings.
The cutting part of the chain is called the CUTTING LINK and this consists of a CUTTING TOOTH (A) and the RAKER LIP (B). The cutting depth is determined by the difference in height between the two.
When you sharpen a cutting tooth there are five important factors to remember:
A
B
It is very difficult to sharpen a chain correctly without the right equipment. We recom­mend you to use a file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.
The following faults will increase the
!
risk of kickback considerably.
FILE ANGLE TOO LARGE
CUTTING ANGLE TOO SMALL
FILE DIAMETER TOO SMALL
FILING ANGLE
CUTTING ANGLE
8 – English
SAFETY INSTRUCTIONS
B. Sharpening
cutting tooth
To sharpen cutting teeth you will need a ROUND FILE and a FILE GAUGE.
1. Check that the chain is correctly tensioned. A slack chain is difficult to sharpen correctly.
2. Always file cutting teeth from the inside face, reducing the pressure on the return stroke. File all the teeth on one side first, then turn the saw over and file the teeth on the other side.
3. File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (.16") the chain is worn out and should be replaced.
min 4 mm (0,16")
C. General advice on setting raker
clearance
When you sharpen the cutting teeth you reduce the RAKER CLEARANCE (cutting depth). To maintain cutting performance you must file back the raker teeth to the recommended height.
On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you maintain this radius or bevel when you adjust the raker clearance.
We recommend the use of a raker gauge to achieve the correct clearance and bevel on the raker lip.
!
WARNING! The risk of kickback is increased if the raker clearance is too large!
English – 9
SAFETY INSTRUCTIONS
D. Adjusting raker clearance
When correction of the raker clearance is made the teeth must be newly sharpened. We recommend that you adjust the raker clearance every third time you sharpen the chain. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.
A FLAT FILE and an RAKER CLEARANCE GAUGE are required to correct the raker clearance.
Place the gauge over the raker lip.
Place the file over the part of the lip that protrudes through the gauge and file off the excess. The clearance is correct when you no longer feel any resistance as you draw the file over the gauge.
Tensioning the saw chain
WARNING!
!
The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.
Check the chain tension every time you refuel. NOTE! A new chain has a running-in period during which you should check and adjust the chain tension more frequently.
As a rule the chain should be tensioned as tightly as possible, but not so tight that you cannot pull it round freely by hand.
A slack chain may jump off and cause serious or even fatal injury.
1. Undo the bar nut.
2. Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. Tighten the chain until it no longer hangs slack beneath the bar.
3. Use the combination spanner to tighten the blade nut while lifting the tip of the bar at the same time. Check that you can pull the chain round freely by hand.
Lubricating cutting equipment
WARNING! Poor lubrication of cutting equipment may
!
A. Chain oil
Chainsaw chain oil must demonstrate good adhesion to the
chain and also maintain its flow caracteristics regardless of whether it is warm summer or cold winter weather.
As a chainsaw manufacturer we have developed an optimal
chain oil which, with its vegetable oil base, is also biodegradable. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage.
If our own chain oil is not available, standard chain oil is
recommended.
In areas where oil specifically for lubrication of saw chains is
unavailable, ordinary EP 90 transmission oil may be used.
Never use waste oil!
This is dangerous for yourself, the saw and the environment.
B. Filling with chain oil
The oil pump is preset at the factory to meet most lubrication requirements and a full oil tank will last about half as long as a tank of fuel. You should therefore check the level in the oil tank regularly to avoid damaging the chain and bar by running out of oil.
cause the chain to snap and lead to serious, even fatal injuries.
10 – English
SAFETY INSTRUCTIONS
C. Checking chain lubrication
Check the chain lubrication each time you refuel. Aim the tip of the saw at a light coloured surface about 20 cm away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.
D. Adjusting chain lubrication
When cutting dry or hard species of wood it may be necessary to increase lubrication. To increase the oil flow, first undo screw (A) then turn the adjuster screw (B) anticlockwise. Re-tighten screw (A). Remember that this will increase the oil consumption and you should therefore check the level in the oil tank more frequently.
A
Procedure if the lubrication does not function:
Check that the oil channel in the bar is not obstructed. Clean if necessary. Check also that the O­ring is in position and is undamaged.
Check that the oil channel in the gear housing is clean. Clean if necessary.
Check that the bar tip sprocket turns freely. If the chain lubrication system is still not working after carrying out the above measures you should contact your service agent.
Checking wear on cutting equipment
A. Saw chain
Check the saw chain daily for:
Visible cracks in rivets and links.
Whether the chain is stiff.
Whether rivets and links
are badly worn.
Compare the existing chain with a new chain to decide how badly it is worn.
When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced.
B. Chain drive wheel
Check regularly the degree of wear on the drive wheel. Change if it is irregularly
B
worn.
C.Vibration damping system
Check regularly that the vibration damper i free from cracks. Check regularly the degree of wear on the rubber elements. Change if worn
D. Guide bar
Check regularly:
Whether there are burrs on the edges of the bar. Remove these with a file if necessary.
Whether the groove in the bar has become badly worn. Replace the bar if necessary.
Whether the tip of the bar is uneven or badly worn. If a hollow forms on one side of the bar tip this is due to a slack chain.
To prolong the life of the bar you should turn it over daily.

Basic working techniques
Observe great care when working close to overhead power lines. Falling branches can result in short-circuiting.
WARNING! Observe the applicable safety regulations
!
!
for work in the vicinity of overhead power lines.
WARNING! This machine is not electrically insulated. If the machine touches or comes close to live electricity lines, it could cause death or serious injury. Electricity can jump from one point to another in the form of a high­voltage arc. The higher the voltage, the further the electricity can jump. Electricity can also be conducted by branches and other objects, especially if they are wet. Always keep a distance of at least 10 m (30 ft) between the machine and live electricity lines and/or objects that are touching them. If you have to work closer than this, always contact the relevant power company to make sure the power is switched off before you start your work.
The machine should be held as close to the body as possible to get the best balance.
Make sure that the tip does not touch the ground.
Do not rush the work, but work steadily until all the branches have been cut back cleanly.
Always drop to idling speed after each working operation. Longer periods running at full throttle without loading the engine can lead to serious engine damage.
Allways cut with the engine at full throttle.
Let the engine drop back to idle between each cut. Long periods at full throttle can cause serious damage to the centrifugal clutch.
WARNING! This machine has a long reach. Make sure
!
Whenever possible position yourself so that you can make the cut at right angles to the branch.
Do not work with the shaft held straight out in front of you (like a fishing rod). This increases the apparent weight of the cutting equipment.
Cut large branches in stages to give better control over where they fall.
Never cut through the swelling at the root of the branch as this will slow down healing and increase the risk of fungal attack.
that no people or animals come closer than 15 m (45 ft) when the machine is running.
90
!
14 – English
Never stand directly underneath a branch that is being cut, otherwise you may suffer serious or even fatal injury.
Use the stop at the base of the bar to provide support during cutting. This will help prevent the cutting equipment from jumping on the branch.
Make an initial cut on the underside of the branch before cutting through the branch from above. This will prevent tearing of the bark, which could lead to slow healing and cause permanent damage to the tree. The first cut should not be deeper than 1/3 of the branch thickness to prevent jamming. Keep the chain running while you withdraw the cutting equipment from the branch to prevent it jamming.
SAFETY INSTRUCTIONS
Use the harness to support the weight of the machine and make it easier to handle.
Make sure you have a firm footing and will not be hampered by branches, stones and other trees.
WARNING!
!
Never use the throttle without having a full view of the cutting equipment.

FUEL HANDLING

Fuel mixture
NOTE!
The machine is fitted with a two-stroke engine and must always be run on a mixture of gasoline and two-stroke oil. It is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel.
WARNING!
!
Gasoline
NOTE! Always use high grade unleaded oil mixed gasoline (minimum 87 RON). Leaded fuel will destroy the catalytic converter and it will no longer serve its purpose.
Always provide good ventilation when handling fuel.
Mixture
Always mix gasoline and oil in a clean container intended for fuel.
Always start by filling half the quantity of gasoline required. Then add the entire oil quantity. Mix (shake) the fuel mixture. Fill the remaining quantity of gasoline.
Mix (shake) the fuel mixture carefully before filling in the machines fuel tank.
Do not mix more than max. one months supply of fuel.
If the machine is not used for a long period of time, the fuel
tank should be emptied and cleaned.

WARNING!
!
The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when handling the machine near flammable substances or vapours.
This engine is certified to
operate on unleaded gasoline.
The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 so­called knocking can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown.
When working at continuous high revs a higher octane rating is recommended.
Two-stroke oil
For the best results use HUSQVARNA two­stroke oil, which has been specially developed for clearing saws and chain saws. Mixing ratio 1:50 (2%).
Never use two-stroke oil intended for water cooled outboard motors, so-called outboard motor oil.
Never use oil intended of four-stroke engines.

MAINTENANCE

Carburetor
Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After your unit has been run 8-10 tanks of fuel the engine has broken in. To ensure that your unit is at peak performance and producing the least amount of harmful emissions after break in, have your authorized servicing dealer, who has a revolution counter at his disposal, to adjust your carburetor for optimum operating conditions.
WARNING! The complete clutch cover with shaft
!
Operation
The carburetor governs the engines speed via the throttle. Air/fuel is mixed in the carburetor. The air/fuel mixture is adjustable. To take advantage of the engine‘s optimal output the adjustment must be correct.
The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitude, gasoline and the type of 2-stroke oil.
The carburetor is equipped with three adjustment possibilities: L = Low speed needle H = High speed needle T = Idle speed adjuster screw
The fuel quantity in relation to the air flow permitted by the throttle opening is adjusted using the L and H-needles. Turning the needles clockwise gives a leaner fuel mixture (less fuel) and turning them anti-clockwise gives a richer fuel mixture (more fuel). A leaner mixture gives high revs while a richer mixture give less revs.
The T-screw regulates the position of the throttle while the engine is idling. Turning the screw clockwise gives a higher idling speed while turning it anti-clockwise gives a lower idling speed.
must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury.
Basic setting
The carburetor is set to its basic setting when test run at the factory. The basic setting should be kept during the machines first working hours. Thereafter the carburetor should be finely adjusted. Fine adjustment should be carried out by a skilled technician.
NOTE! If the cutting attachment rotates/moves while the engine is idling the T-screw should be turned anti-clockwise until the cutting attachment stops.
Rec. idling speed: 2 700 rpm.
Recommended max. speed: See “Technical Data” .
WARNING! If the idling speed cannot be adjusted so
!
that the cuttingequipment stops, contact your service workshop. Do not use the machine until it has been correctly adjusted or repaired.
Fine adjustment
When the machine has been run-in the carburetor should be finely adjusted. The fine adjustment should be carried out by qualified person. First adjust the L-jet, then the idling screw T and then the H-jet.
Conditions
Before any adjustments are made the airfilter should be clean and the airfilter cover fitted. Adjusting the carburetor while a dirty airfilter is in use will result in a leaner mixture when the filter is finally cleaned. This can give rise to serious engine damage.
Carefully turn the L and H needle to the mid point between fully turned in and fully turned out..
Do not attempt to adjust the needles beyond the stops as damage can occur.
Now start the machine according to the starting instructions and run it warm for 10 minutes.
NOTE! If the cutting attachment rotates/moves the T screw should be turned anti-clockwise until the cutting attachment stops.
Low speed needle L
Try to find the highest idling speed, turning the low speed needle L clockwise respectively counter­clockwise. When the highest speed has been found, turn the low speed needle L 1/4 turn counter-clockwise. NOTE! If the cutting­equipment rotates/moves in the idling position, turn the idling speed screw T counter-clockwise until the cutting attachment stops.

MAINTENANCE
Final setting of the idling speed T
Adjust the idling speed with the screw T, if it is necessary to readjust. First turn the idle speed adjusting screw T clockwise until the cutting­eqipment starts to rotate/ move. Then turn, counter-clock­wise until the cutting­equipment stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the cuttingequipment starts to rotate/move.
CAUTION! Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the cutting attachment stops. Do not use the machine until it has been properly adjusted or repaired.
Correctly adjusted carburetor
A correctly adjusted carburetor means that the machine accelerates without hesitation and the machine 4-cycles a little at max speed. Furthermore, the cuttingequipment, must not rotate/move at idling. A too lean adjusted low speed needle L may cause starting difficulties and bad acceleration. A too lean adjusted high speed needle H gives lower power = less capacity, bad acceleration and/or damage to the engine. A too rich adjustment of the two speed needles L and H gives acceleration problems or too low working speed.
High speed needle H
The high speed needle affects the machine’s power, speed, temperature and fuel consumption. A too lean adjustment on the high speed needle H (the high speed needle H is screwed in too much) gives a too high speed resulting in engine damage. Do not allow the engine to run at full speed for more than 10 seconds. Apply full throttle and turn the high speed needle H slowly anticlockwise until the engine runs unevenly. The high speed needle H is then turned slowly clockwise a little until the engine runs smoothly. Note the engine should be run unloaded when adjusting the high speed needle. Therefore dismantle the cutting equipment, nut, support flange and disc drive before adjusting the high speed needle. The high speed needle is adjusted correctly when the machine splatters’ a little .

NOTE! For optimum setting of the carburetor, contact a qualified servicing dealer who has a revolution counter at his disposal.

MAINTENANCE
Muffler
NOTE!
Some mufflers are fitted with a catalytic converter. See Technical data to see whether your machine is fitted with a catalytic converter.
The muffler is designed to dampen the noise level and to direct the exhaust fumes away from the user. The exhaust fumes are hot and can contain sparks, which can result in fire if the exhaust fumes are directed towards a dry and inflammable material. Some mufflers are equipped with a special spark arrest screen. If your machine is fitted with this type of screen it should be cleaned regularly. This is done using a wire brush. On mufflers without a catalytic converter the screen should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter the screen should be checked and cleaned monthly. If the
screen is damaged it should be replaced. If the screen is
frequently blocked, this can be a sign that the function of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked screen will cause the engine to overheat resulting in damage to the cylinder and piston. Also see under Maintenance.
NOTE!
Never use a machine with a defective muffler.
Cooling system
To maintain as low opera­ting temperature as possible the engine is equipped with a cooling system. The cooling system consists of:
1.An air intake on the starter unit.
2.Cooling fins on the flywheel.
3.Cooling fins on the cylinder
4.Cylinder cover (leads cold air onto the cylinder).
Clean the cooling system using a brush at least once a week, in difficult conditions more often.
A dirty or blocked cooling system leads to the engine overheating resulting in damage to the cylinder and piston.
Spark plug
The condition of the spark plug is affected by:
An incorrect carburetor setting.
An incorrect fuel mixture (too much or faulty oil).
A dirty air filter.
These factors cause deposits on the spark plug electrode that may result in malfunction or starting
difficulties.

WARNING! Mufflers fitted with catalytic converters become extremely hot during use and after stopping. This also applies at idling speeds. Contact can result in burns to the skin. Be observant to the risk of fire!
If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if necessary. NOTE! Always use the recommended type of spark plug. An incorrect spark plug can damage the cylinder/piston.
MAINTENANCE
Air filter
The air filter should be cleaned regularly removing dust and dirt to avoid:
carburetor malfunction
starting problems
reduced engine power
unnecessary wear to
engine parts
abnormal fuel consumption
Clean the filter after every 25 hours or more regularly if operating conditions are exceptionally dusty.
Cleaning the air filter
Dismantle the air filter cover and remove the air filter. Wash in clean, warm soapy water. Ensure that the filter is dry before refitting. An air filter used for a long period of time can never be cleaned completely. Therefore it is necessary to replace the filter from time to time with a new filter. A damaged air filter must always be replaced. If the machine is used in dusty conditions the air filter should be soaked in oil, see the section on Oiling the air filter“.
Oiling the air filter
Always use HUSQVARNA filter oil, order no. 503 47 73-01. The filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact. Put the filter in a plastic bag and the pour the filter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter on the machine. Never use common engine oil. This would drain through the filter quite quickly and collect in the bottom.
NOTE: Use only HUSQVARNA replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specifically recommended by HUSQVARNA.
