The air ﬁlter must be regularly cleaned to remove dust and dirt
in order to avoid:
Loss of engine power
Unnecessary wear to engine parts
Excessive fuel consumption.
Clean the ﬁlter every 8 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
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.
The sweeper is often used under dusty conditions. It is
extremely important to maintain the air ﬁlter regularly, often
daily. The air ﬁlter must be oiled in order to work
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.
The spark plug condition is inﬂuenced by:
Incorrect carburetor adjustment.
An incorrect fuel mixture (too much or incorrect type of
A dirty air ﬁlter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
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 (0,020"). The spark plug
should be replaced after about a month in operation or earlier
CAUTION! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/cylinder.
IMPORTANT! Use only HUSQVARNA replacement parts.
Use of other brands of replacement parts can cause
damage to your unit or injury to the operator or others. Your
warranty does not cover damage or liability caused by the
use of accessories and/or attachments not speciﬁcally
recommended by HUSQVARNA.
