MAINTENANCE

Air filter

Spark plug

The air filter should be cleaned regularly removing dust and dirt to avoid:

• carburettor 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

The condition of the spark plug is affected by:

An incorrect carburettor 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.

0,5 mm

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.

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.

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.

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.

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.

!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.
