Steps bef

 

ore using a new power 

cutter.

 

 

Please read the operator’s manual carefully.

Check the cutting blade’s mounting, see the chapter 
”Assembly”.

Start the engine and check the idling setting, see 
instructions under the heading Maintenance. When the 
carburettor is set correctly the cutting blade should be still 
while idling. Setting of the idle speed is described in the 
Operator’s Manual. Set the correct speed according to 
these instructions. Do not use the power cutter if the idle 
speed is not adjusted correctly!

Let your Husqvarna dealer regularly check the power 
cutter and make essential adjustments and repairs.

Husqvarna Construction Products has a policy of continuous 
product development. Husqvarna reserves the right to modify 
the design and appearance of products without prior notice 
and without further obligation introduce design modifications.
