Husqvarna 327LS, Operator'S Manual

MAINTENANCE

20 – English

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 0.5 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. Check that the spark plug is fitted with a 
suppressor.

Two-piece shaft (327LDx)

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) on models with two-piece 
shafts 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:

•

Carburettor malfunctions

•

Starting problems

•

Loss of engine power

•

Unnecessary wear to engine parts.

•

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. 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.

If the machine is used in dusty conditions the air filter 
should be soaked in oil. See instructions under the 
heading Oiling the air filter.

Oiling the air filter

Always use HUSQVARNA filter oil, art. no. 531 00 92-48. 
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 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 to the machine. Never 
use common engine oil. This would drain through the filter 
quite quickly and collect in the bottom.
