WARNING
•
Make sure that the engine has stopped and is cool
before performing any service to the machine.
Contact with moving cutting head or hot muffler
may result in a personal injury.
AIR FILTER
• The air filter, if clogged, will reduce the engine perfor-
mance. Check and clean the filter element in warm,
soapy water as required. Dry completely before in-
stalling. If the element is broken or shrunk, replace
with a new one.
