•

Clean the machine daily by rinsing it with clean water after 
the work is finished.

•

Clean the cooling air intake when needed.

•

If the machine is low on power, difficult to start or runs 
poorly at idle speed: always check the spark plug first 
before taking other steps.

•

Ensure that the spark plug cap and ignition lead are 
undamaged to avoid the risk of electric shock.

•

If the spark plug is dirty, clean it and at the same time 
check that the electrode gap is 0.5 mm. Replace if 
necessary.

These factors cause deposits on the spark plug electrodes, 
which may result in operating problems and starting 
difficulties.

•

An incorrect fuel mixture (too much or incorrect type of 
oil).

•

A dirty air filter.

•

Check that nuts and screws are tight.

•

For correct tensioning of the drive belt, the square nut 
should be positioned opposite the marking on the belt 
cover.

•

The tension of a new drive belt must be readjusted after 
one or two tanks of fuel have been used.

•

When the machine is equipped with a friction retarder, a 
scraping sound can be heard from the bearing housing 
when the blade is turned by hand. This is quite normal. 
Please contact an accredited Husqvarna workshop if you 
have any questions.

•

The drive belt is enclosed and well protected from dust 
and dirt.

•

When the drive belt is to be tensioned, release the bolts 
holding the cutting arm.

•

Screw the adjuster screw so that the square headed nut 
comes opposite the marking on the cover. This 
automatically ensures that the belt has the correct 
tension.

•

Tighten both of the screws holding the cutting head using 
a T-wrench.

NOTICE! A dirty or blocked air intake results in the machine 
overheating which causes damage to the piston and 
cylinder.

NOTICE! Always use the recommended spark plug type! 
Use of the wrong spark plug can damage the piston/
cylinder.
