Air filter maintenance
A contaminated air filter will reduce output. Fuel consumption and hazardous substance quantity in the
exhaust increase. Starting is made more difficult as well.
Interim emptying of the air filter
Turn vibration dial (29) to perform rough interim emptying of the air filter during work. The air filter
box and air filter are shaken so that loose dust falls off. Slightly tilt the power tool back and let dust
fall out of the intake openings. Turn the vibration dial repeatedly if required.
Cleaning the air filter
At weekly intervals or when the engine output is clearly reduced, the air filter must be removed and
cleaned thoroughly.
Danger of contamination for the filter inside!
Only open the guard and air filter box lid in a clean environment.
