INTRODUCTION

General

Arrangement

This manual provides a detailed description of procedures

for trouble shooting, repair and testing of the chainsaw. The

safety precautions that should be taken during repair work

are also described.

This workshop manual can be used in two different ways:

• Repair of a specific sub-assembly on the chainsaw.

• Dismantling and reassembly of the whole chainsaw.

Safety

Repair of a specific sub-assembly

When a specific sub-assembly on the chainsaw is to be

repaired, proceed as follows:

Note! The section dealing with safety should be read

and understood by all who carry out repair or

service work on the chainsaw.

1. Look up the page referring to the relevant sub-assembly.

2. Carry out the steps: Dismantling

Cleaning and inspection

Reassembly

Warning markings are shown both in this manual and on the

chainsaw itself. See page 5. If a warning mark on the

chainsaw has been damaged or is missing, it must be

replaced immediately in order to maximise safety when the

saw is in use.

Dismantling and reassembly of the entire chainsaw

When the entire chainsaw is to be dismantled and

reassembled, proceed as follows:

Target Audience

1. Look up page 16, which deals with the recoil starter and

carry out the instructions under the heading Dismantling .

This workshop manual is written for personnel assuming

that they have general knowledge of service and repair of

small engines.

2. Work forwards through the manual and carry out

Dismantling instructions in the order that the sections

occur.

The manual should be read and understood by all personnel

who will carry out service and repair work on the chainsaw.

The manual is also suitable for use in the training of new

employees.

3. Return to recoil starter on page 16 and follow the

instructions under Cleaning and inspection .

4. Work forward through the manual and carry out Cleaning

and inspection in the order that the sections occur.

Changes

5. Order or fetch all the required spare parts from the spares

warehouse.

As production continues, changes will be introduced

successively to the chainsaw. If at any time these changes

influence service and/or spares, special service

announcements will be sent out, which means that this

manual will cease to be current with time. In order to avoid

problems, the manual should always be read together with

all service announcements that apply to the specific model

of chainsaw.

6. Look up page 44 which deals with the crankcase and

carry out the instructions under Assembly.

7. Work backwards through the manual and carry out

Reassembly instructions as the sections occur.

In order to improve understanding, some sections begin with

a Description of the relevant sub-assembly.

Tools

For specific procedures special tools are required. In this

workshop manual, all the service tools required are listed.

Their use is described in the appropriate section.

Numbering

Location indicators for components shown in the figures are

marked A, B, etc.

The figures are numbered 1, 2 etc.

The location indicators and figure numbers start again from

A, 1 etc. at the beginning of each new section.

Always use Husqvarna original:

SAFETY REGULATIONS

General instructions

Special instructions

Workshops where chainsaws are serviced must be equipped

with safety equipment in accordance with local regulations.

The fuel used in the chainsaw poses the following hazards:

1. The fluid and its fumes are poisonous.

2. Can cause skin irritation.

3. Is highly inflammable.

No one should repair the chainsaw without first having read

and understood the contents of this workshop manual.

The guide bar, chain and clutch cover (chain brake) must be

assembled before the chainsaw is started, otherwise the

clutch may come loose causing personal injury.

The following warning texts are to be found in this manual in

certain places. The warning texts occur before the procedure

to which they refer.

Wear ear defenders when testing the chainsaw.

WARNING!

The warning text indicates a risk of

personal injury if instructions are not

followed.

Do not use the saw before it has been adjusted so that the

chain is still when idling.

After testing, do not touch the silencer until it has cooled. Risk

for burns.

NOTE!

The warning text indicates a risk of damage

to equipment if instructions are not followed.

Inadequate lubrication of the chain can result in the chain

breaking, which can cause serious or life threatening injury.

Make sure that the starter recoil spring does not fly out and

cause personal injury.

If the spring is tensioned when the cord pulley is removed,

the spring can fly out causing personal injury.

When removing the pressure spring for the chain brake,

ensure that the brake is in the on position, otherwise the

spring can fly out causing personal injury.

After repair, the chain brake must be checked in accordance

with the instructions on page 13.

When replacing the crankshaft bearings note that the

crankcase halves are hot. Use protective gloves.

When using compressed air, the air jet should never be

pointed towards the body. Air can be forced into the blood

stream, which can cause fatality.
