MAINTENANCE

Angle gear

The angle gear is filled with a

sufficient quantity of grease

at the factory. However,

before using the machine

you should check that the

angle gear is filled to 3/4

with grease. Use Husqvarna

special grease.

Normally, the grease does

not need to be changed

except when the angle gear is

repaired.

Two-part shaft

The end of the drive axle in

the lower shaft should be

lubricated with grease every

30 hours. There is a risk that

the drive axle ends (splined

coupling) on two-part shafts

jam if they are not lubricated

regularly.

WARNING!

Always discard a blade that is bent,

twisted, cracked, shattered or damaged in

any other way. Never attempt to straighten

a twisted blade for use again. Only use

original blades of the prescribed type.

• See the cutting

equipment’s packaging for

correct filing instructions.

• The blades are sharpened

using a single cut flat file.

• Sharpen all edges equally

to maintain the balance of

the blade.

Filing the grass blade

WARNING!

Always stop the engine before starting

work on any part of the cutting equipment.

This continues to rotate even after the

throttle has been released. Ensure that the

cutting equipment has stopped completely

and remove the cable from the spark plug

before you start to work on it.

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.
