Maintenance (continued)
Gearcase lubrication
■
Lubricate the cutter assembly
gearcase by pumping one or two
strokes of lithium based 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
Every 50 hours of operation; more
frequently in dusty conditions:
Remove and clean the cylinder cover
and clean dirt and debris from the
cylinder 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 genuine 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
damaged easily.
■
Before reinstalling the new filter
element, 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
servicing 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.
