SERVICING AIR FILTER ELEMENTS
AVOID ENGINE DAMAGE!
When removing the air fi lter element, an open-
ing directly to the internal parts of the engine is
created.
Be sure that nothing falls into the canister that
could make its way into the engine. Have the new
fi lter element ready to install immediately after the
old element has been removed.
ATTENTION: Avoid damage to your
engine! Improper service to the engine air
fi lter can result in severe engine damage.
• Inspect fi lter daily in extreme heat, dust,
or other severe conditions.
• Never run engine without proper air fi lter
installed.
• Never wash or clean paper fi lter element.
