WARNING
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 before use.
A clogged air filter may increase fuel consumption while cutting down the engine power.
•Never operate the blower without an air filter or with a deformed or broken filter element because unfiltered dusty air will quickly ruin the engine.
[170BT/170BF]
•Never clean the paper filter by tapping on it. Doing so may break the element, causing dust to get sucked into the blower and damaging the engine.
CLEANING AIR FILTER:
[130BT] (F27)
1. Unscrew the knob and remove the air cleaner cover.

2.Wash the filter element in fresh, non flammable cleaning solution (ex. warm soapy water) and then dry.
(Clean the air filter once in a week.)
3.Reinstall the filter. 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.
4.Hook the slots of cover (4) on the tabs of body (5) and screw the knob.
[170BT/170BF] (F28)
1.Unscrew 2 knob bolts and remove the air cleaner cover. Then remove the prefilter mounted inside the air cleaner cover.
