Service And Adjustments - Husqvarna 6521RS El Manual Del Propietario

CLEANING
IMPORTANT: For best performance,
keep mower housing free of built-grass
and trash. Clean the underside of your
mower after each use.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with plug.
• Clean the underside of your lawn mower
by scraping to remove build-up of grass
and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
WARNING: To avoid serious injury, before
performing any service and adjustments:
1. Release control bar and stop engine.
2. Make sure the blade and all moving
parts have completely stopped.
3. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
