Maintenance (continued)
Gearcase lubrication
■
Lubricate the cutter assembly
gearcase by pumping one or two
strokes of lithium-base grease into
the grease fitting (A) using a lever-
type grease gun.
CAUTIOn!
Over lubricating can cause the
gearcase to operate sluggishly and
can cause grease to leak out.
50-hour maintenance
Ever y 50 hours of operation; more
frequently in dusty conditions:
Remove and clean the cylinder cover
and clean dirt and debris from the cyl-
inder cooling fins.
Remove and replace the fuel filter
element.
■
Use a hooked wire to extract the fuel
filter from inside the fuel tank. Inspect
the fuel filter element. If it shows signs
of contamination, replace with a genu-
ine Shindaiwa replacement fuel filter
element.
CAUTIOn!
Make sure you do not pierce the fuel
line with the end of the hooked wire.
The line is delicate and can be dam-
aged easily.
■
Before reinstalling the new filter ele-
ment, inspect the condition of all the
fuel system components (fuel pick-up
line, fuel return line, tank vent line,
tank vent, fuel cap and fuel tank). If
damage, splitting or deterioration is
noted, the unit should be removed
from service until it can be inspected
or repaired by a Shindaiwa-trained
service technician.

Fuel filter maintenance
Federal EPA regulations require all model year 2012 and later gasoline powered
engines produced for sale in the United States to be equipped with a special low
permeation fuel supply hose between the carburetor and fuel tank. When servic-
ing model year 2012 and later equipment, only fuel supply hoses certified by EPA
can be used to replace the original equipment supply hose. Fines up to $37,500
may be enforced for using an un-certified replacement part.
