SAFETY INSTRUCTIONS
Cutting equipment
This section describes how to choose and maintain your cutting equipment in order to: S Obtain maximum cutting performance.
S Extend the life of cutting equipment.
General rules:
1.Only use cutting attachments with the guards we recommend! See the section on “Technical Data”.
2.Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.
WARNING: Never use a machine with faulty safety equipment. The
machine’s safety equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your servicing dealer to get
it repaired. Use of a machine with faulty safety equipment increases the risk of serious personal injury to the operator or others.
IMPORTANT!
This section describes how to choose and
maintain your cutting equipment in order to: Obtain maximum cutting performance. Extend the life of cutting equipment.
Only use cutting attachments with the guards we recommend! See the section on
“Technical data”.
Refer to the instructions for the cutting attachment to check the correct way to load the trimmer line and the correct line diameter.
115374327 Rev. 6 5/31/12
Trimmer head
SOnly use the recommended cutting attachments. See the section on “Technical data”.
SSmaller machines generally require small trimmer heads and vice versa. This is because when clearing using trimmer line the engine must throw out the trimmer line radially from the trimmer head and overcome the resistance of the grass being cleared.
SThe length of the trimmer line is also important. A longer trimmer line requires greater engine power than a shorter
trimmer line of the same diameter.
SMake sure that the cutter on the trimmer guard is intact. This is used to cut the
trimmer line to the correct length.
STo increase the life of the trimmer line it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.
IMPORTANT!
Always ensure the trimmer line is wound
tightly and evenly around the drum, otherwise the machine will generate harmful vibration.
WARNING: Always stop the engine before doing any work on the
cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the
lead from the spark plug before you start to work on it.

STo ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment.
English---9
SAFETY INSTRUCTIONS
SCAUTION! Do not use the machine unless you are able to call for help in the event of an accident.
2.Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc.
3.Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.
4.Switch off the engine before moving to another area.
5.Never put the machine down with the engine running.
Basic working techniques
SAlways slow the engine to idle speed after each working operation. Long periods at
full throttle without any load on the engine can lead to serious engine damage.
SIt is recommended that the engine not
be operated for longer than 1 minute at full throttle.
WARNING: Sometimes branches or grass get caught between the
guard and cutting attachment. Always stop the engine before cleaning.
Grass trimming using a trimmer head
Trimming
SHold the trimmer head just above the ground at an angle. It is the end of the trimmer line that does the work. Let the trimmer line work at its own pace. Never press the trimmer line into the area to be cut.
S The trimmer grass and weeds up against walls, fences, trees and borders, however it can also damage
sensitive bark on trees and bushes, and damage fence posts.
SReduce the risk of damaging plants by shortening the trimmer line to 4--4 1/2 inches
(10--12 cm) and reducing the engine speed.
SWhen trimming you should use less than full throttle so that the trimmer line lasts longer and to reduce the wear on the trimmer head.
Clearing
SThe clearing technique removes all unwanted vegetation. Keep the trimmer
head just above the ground and tilt it. Let the end of the trimmer line strike the ground around trees, posts, statues and the like. IMPORTANT! This technique increases the wear on the trimmer line.
S The must be fed forward more often when working against stones, brick, concrete, metal
fences, etc., than when coming into contact with trees and wooden fences.
Cutting
SThe trimmer is ideal for cutting grass that is difficult to reach using a normal lawn mower. Keep the trimmer line parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as
this can ruin the lawn and damage the tool.
SDo not allow the trimmer head to con-- stantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.

English---10 |
SAFETY INSTRUCTIONS
Sweeping
SThe fan effect of the rotating line can be used for quick and easy clearing up. Hold the trimmer line parallel to and above the area to be swept and move the tool to and fro.
SWhen cutting and sweeping you should use full throttle to obtain the best results.
115374327 Rev. 6 5/31/12
WARNING: Sometimes branches or grass get caught between the guard and cutting attachment or wrapped around the shaft. Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating,
as this can result in serious injury. Stop the engine and cutting equipment before you remove material.
WARNING: Watch out for thrown objects. Always wear
approved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. Stop the machine immediately if anyone
approaches. Never swing the machine around without first checking behind you to make sure no one is within the safety zone.

MAINTENANCE
The owner is responsible for the performance of all required maintenance as defined in the operator’s manual.
Carburetor
Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8--10 tanks of fuel, the engine will be run--in. To ensure that it continues to run
at peak performance and to minimize harmful exhaust emissions after the run--in period, ask your servicing dealer to adjust your carburetor.
WARNING: The complete clutch, clutch cover, and shaft must be
fitted before the machine is started, otherwise parts could come loose and cause personal injury.
Function
SThe carburetor governs the engine’s speed via the throttle control. Air and fuel
are mixed in the carburetor.
SThe T--screw regulates the throttle setting
at idle speed. If the T--screw is turned clockwise this gives a higher idle speed; turning it counterclockwise gives a lower idle speed.
Basic setting
SThe basic carburetor settings are adjusted during testing at the factory. Fine adjustment should be carried out by a skilled technician.
CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment
screw T should be turned counterclockwise until the cutting attachment stops.
Rec. idle speed:
See “Technical data” section.
Recommended max. speed:
See “Technical data” section.
WARNING: If the idle speed cannot be adjusted so that the cut-
ting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.
Fine adjustment of the idle speed-T
Adjust the idle speed using the idle adjustment screw--T if it is necessary to readjust. First, turn the idle adjustment screw--T clockwise until the cutting attachment starts to rotate. Then, turn the screw counterclockwise until the cutting attachment stops.
115374327 Rev. 6 5/31/12
The idle speed is correctly adjusted when the engine will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.
Idle Speed
Screw--T
WARNING: If the idle speed cannot be adjusted so that the cutting
attachment stops, contact your servicing dealer. Do not use the machine until it has been correctly adjusted or repaired.
Unit/Maintenance Safety
Disconnect the spark plug before performing maintenance, except carburetor adjustments.
Muffler
CAUTION! Muffler is fitted with a catalytic converter designed to reduce exhaust gas emissions.
The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material.
Mufflers are equipped with a special spark arrestor mesh. The mesh should be checked and, if necessary. cleaned by a
servicing dealer. If the mesh is damaged, it should be replaced. If the mesh is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your servicing dealer to
inspect the muffler. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston.
English---18
MAINTENANCE
Muffler bolts
Spark arrestor mesh
CAUTION! Never use a machine that has a faulty or loose muffler. Ensure the muffler bolts are tight.
CAUTION: Mufflers fitted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire!
WARNING: The inside of the muffler contain chemicals that may
be carcinogenic. Avoid contact with these elements in the event of a damaged muffler.
WARNING: Engine exhaust fumes contain carbon monoxide,
which can cause carbon monoxide poisoning. DO NOT start or run the machine indoors, or anywhere that is poorly ventilated. The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material!
Spark plug
The spark plug condition is influenced by: S Incorrect carburetor adjustment.
SAn incorrect fuel mixture (too much or incorrect type of oil).
S A dirty air filter.
These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.
If the machine is low on power, difficult to
start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.024″ (0.6 mm). The spark plug should be
replaced after about a month in operation or earlier if necessary.
CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.
115374327 Rev. 6 5/31/12
0.024″ (0.6 mm)
Two--piece shaft
The drive shaft end in the lower shaft should be lubricated with grease every 30 hours. There is a risk that the drive shaft ends (splined coupling) will seize if they are not lubricated regularly.
Air filter
The air filter must be regularly cleaned to remove dust and dirt in order to avoid:
S Carburetor malfunctions
S Starting problems
S Loss of engine power
S Unnecessary wear to engine parts S Excessive fuel consumption
Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Rinse thoroughly. Ensure that the filter is dry before refitting it.
An air filter that has been in use for a long
time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced.
English---19
MAINTENANCE
Bevel gear (128LD)
The bevel gear is filled with the right quantity
of grease at the factory. However, before using the machine you should check that the bevel gear is filled three--quarters
full with grease. Use HUSQVARNA special grease.
The grease in the bevel gear does not normally need to be changed except if repairs are carried out.
Maintenance schedule
Below you will find some general maintenance instructions.
Daily maintenance
S Check throttle trigger and throttle trigger lockout function.
S Check that the stop switch works correctly.
S Check that there are no fuel leaks from the engine, tank or fuel lines.
SCheck that the cutter does not rotate when the engine is idling.
S Clean the outside of the machine.
S Check that the harness is not damaged.
SCheck that the cutting attachment guard is not damaged or cracked.
