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!

Cutting equipment

A trimmer head is intended for trimming grass.

Checking, maintaining and servicing the machine’s safety equipment

IMPORTANT!

All servicing and repair work on the machine requires special training. This is especially true of the machine’s safety equipment. If your machine fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your machine is not a servicing dealer, ask him for the address of your nearest service agent.

Stop switch

S Start the engine and make sure the engine

stops when you push and hold the stop switch.

Cuttingattachmentguard

S Ensure that the guard is undamaged and

is not cracked.

S Replace the guard if it has been exposed

to impact or is cracked.

SAFETY INSTRUCTIONS

Muffler

S Never use a machine that has a faulty

muffler.

S Regularly check that the muffler is securely

attached to the machine.

S The muffler on this unit is equipped with a

special spark arrestor mesh. The mesh should be checked and, if necessary. cleaned by a servicing dealer. A blocked mesh will cause the machine to overheat, which can lead to serious damage. Never use a mufflerwith adefective spark arrestor mesh. See the Maintenance section.

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 service agent to getitrepaired.

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 “T echnical data”. Refer to the instructions for the cutting attachment to check the correct way to load the trimmer line and the correct line diameter.

Trimmerhead

S Only use the recommended cutting at-

tachments. See the section on “Technical data”.

S Smaller 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.

S The length of the trimmer line is also im-

portant. A longer trimmer line requires greater engine power than a shorter trimmer line of the same diameter.

S Make sure that the cutter on the trimmer

guard is intact. This is used to cut the trimmer line to the correct length.

S Toincrease 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 en-

gine 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.

SAFETY INSTRUCTIONS

S CAUTION! 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 standsafel y. 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 or while the cutting attachment is rotating.

Basic working techniques

S Always 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.

S It 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

S Reduce the risk ofdamaging plants by

shortening the trimmer line to 4- -4 1/2 inches (10- -12 cm) and reducing the engine speed.

S When 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

S The clearing technique removes all un-

wanted 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. CAUTION! This technique increases the wear on the trimmer line.

S The trimmer line wears quicker and 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

S The 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.

S Hold 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 line can easily remove 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.

115374527 Rev. 1 4/15/10

S Do 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--- 9

SAFETY INSTRUCTIONS

Sweeping

S The 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.

S When cutting and sweeping you should

use full throttle to obtain the best results.

WARNING: Neither the operator

of the machine nor anyone else may attempt to remove the cut material while the engine is running or the trimmer line is rotating, as this can result in serious injury. Stop the engine and trimmer head before you remove material that has wound around the drive shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burned if you touch it.

WARNING: Watch out for thrown

objects. Always wear eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. canbethrownupintotheeyes

causing blindness or serious injury. Keep unauthorized persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 50 feet (15 meters). Stop the machine immediately if anyone approaches.

The spark plug condition is influenced by:

S Incorrect carburetor adjustment. S An incorrect fuel mixture (too much or in-

correct 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.

Muffler bolts

Spark arrestor mesh

CAUTION! Never use a machine that has a faulty or loose muffler. Ensure the muffler bolts are tight.

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.

MAINTENANCE

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.

Bevel gear

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.

Maintenance schedule

Below you will find some general maintenance instructions.

Daily maintenance

S Check throttle trigger function. S Check that the stop switch works

correctly.

S Check that there are no fuel leaks from

the engine, tank or fuel lines.

S Check 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. S Check that the blade guard is not dam-

aged or cracked.

S Replace the blade guard if it is exposed to

impact or is cracked.

S A non--balanced trimmer head induces

heavy vibrations that may damage the machine.

S Check that nuts and screws are tight. S Check that the screws that hold the bevel

gear are tight.

S Check that the trimmer head is tight.

Weekly maintenance

S Check the starter and starter cord. S Clean the carburetor area. S Clean the outside of the spark plug. Re-

move it and check the electrode gap. Adjust the gap to 0.024″ (0.6 mm), or replace the spark plug. Use resistor spark plug Champion RCJ--8Y or equivalent.

S Clean the cooling fins on the cylinder and

check that the air intake near the starter is not blocked.

S Check that the bevel gear is filled with

grease up to 3/4 full. Use special grease.

S Clean the air filter.

Monthly maintenance

S Clean the fuel tank. S Clean the outside of the carburetor and

the space around it.

S Clean the fan and the area around it. S Check fuel lines for cracks or other dam-

age. Change if necessary.

S Change the fuel filter in fuel tank. S Check the clutch, clutch springs and the

clutch drum for wear. Replace if necessary.

S Check electrical wires and connections. S Replace the spark plug. Use resistor

spark plug Champion RCJ--8Y or equivalent.

S Change the air filter.

The grease in the bevel gear does not normally need to be changed except if repairs are carried out.
