2. Use neutral detergent and warm water to
clean the filter element. After cleaning, air
dry the element completely. Place the
filter element into the air cleaner housing
and press the cover against the housing
until it clicks. Never forget to attach the
screen. If the screen is not attached, the
cleaner will not seal properly and the
dusts come into the cylinder.
• Make sure that the engine has stopped
and is cool before performing any
service to the blower. Contact with
rotating blower fan or hot muffler may
result in a personal injury.
■
AIR CLEANER
• Check the air cleaner every 25 hours of
use or more frequently if used under dusty
conditions. A clogged air filter may
increase fuel consumption while cutting
down the engine power. Never operate
the blower without the air filter or with a
deformed filter element because unfiltered
dusty air will quickly ruin the engine.
CLEANING AIR FILTER:
1. Remove the air cleaner cover by pulling
the tab on bottom and take out the filter
element.
