Every 25 hours (more often in dusty, dirty
conditions) wash the foam element in liquid soap
and warm water. When the element is clean,
rinse it thoroughly.
Dry the element by squeezing it in a clean cloth
(do not wring). Allow the element to air dry.
Follow engine manufacturer’s recommendation
for treatment of pre cleaner prior to installation.
On Briggs & Stratton and Kawasaki engines,
replace the spark plug(s) every 100 operating
hours.
On Kohler engines, check the spark plug(s) every
200 operating hours.
If the insulator on the spark plug(s) is light brown or
gray, the engine is running properly. A black
coating on the insulator indicates the air cleaner
may be dirty.
IMPORTANT: Never clean the spark plug(s).
Always replace the spark plug(s) when it has a
black coating, worn electrodes, an oily film, or
cracks.
