WARNING
• Make sure that the engine has stopped and is cool
before performing any service to the machine. Contact
with hot muffler may result in a personal injury.
• Do not modify the sprayer or dismantle the engine.
• When replacing parts please use Husqvarna original
parts or designated parts.

Air cleaner
• After every 25 hours of operation, please remove
the air cleaner cover and inspect the element. If it is
too dirty, wash it carefully in warm water containing a
neutral detergent, and return it to its original position
after drying it thoroughly.
• If the element is distorted or damaged, please replace
it with a new one.

b. Air cleaner cover
IMPORTANT
• If the air cleaner element is blocked, the efficiency
of the engine will be reduced. In addition, the engine
interior will suffer abnormal wear if operated without
the element or if continually operated with a distorted
or damaged element fitted.
■
Fuel filter
After every 25 hours of operation, empty the fuel tank,
detach the fuel filter from the tank, and remove all dirt. If
the filter is too clogged, please replace it with a new one.
•
a. Fuel filter
IMPORTANT
• If the fuel filter is clogged, the engine speed may be
limited or speed fluctuations may occur.
• If the engine is operated without a fuel filter, dirt will ac-
cumulate in the carburetor and cause it to malfunction.

WARNING
• Do not touch the spark plug with your bare hands im-
mediately after operation, as there is the risk of burns
due to high temperature.
• After every 50 hours of operation, detach the spark
plug and remove dirt from the electrodes with a wire
brush or similar.
