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.
Fuel filter
When the engine runs short of fuel supply, check the fuel
cap and the fuel filter for blockage.
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.
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.
Bevel gear
There is a grease nipple on the gearbox. Use a grease
gun to top up with grease. This should be carried out after
approximately every 25 working hours. Use Husqvarna
special grease.
Remove the drive disc or the side bolt in the gear cae
before installing new grease to arrange for old grease to
exit.
CAUTION! When removing and installing the drive disc,
use care not to allow any dirt and dust entering into the
gear case.

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
