G120F/G160F/G200F Part III Maintenance
- 25 -
3-4 Air cleaner
A dirty air filter will restrict fair flow to the carburetor, reducing engine performance. If the engine
is operated in dusty areas, clean the air cleaner more often than specified in the MAINTENANCE
SCHEDULE.
Washing filter element with gasoline or flammable solvents many cause
fire or explosion, please use soapy water or nonflammable solvent.
Operating the engine without an air filter element or with a damaged air filter will
allow dirt to enter the engine, causing rapid engine wear.
1. Dual-filter-element air cleaner
1) Remove the wing nut and air cleaner cover.
2) Remove the wing nut and take out paper element
and foam element.
3) Remove the foam filter from the paper filter.
4) Check both filter elements and replace them if they
are damaged. Normally paper element may be
replaced at the scheduled maintenance interval.
Clean paper element:
Tapping paper element several times and then blow
compressed air (at no more than 207KPa) through the
filter from the inside. Never try to brush off dirt.
Brushing will force dirt into the filter fibers.
Cleaning foam element:
Clean the foam element in warm water with detergent, or in a nonflammable or high flash point
solvent and allow it to dry, then soak the air filter element in clean engine oil and squeeze out the
excess oil.
5) Clean air cleaner case, cover and rubber gasket, and be careful to prevent dirt from entering
the air duct that leads to carburetor.
