Scag Power Equipment STT-31BSD Manuel D’Utilisation

Fill the fuel tank at the beginning of each operating day to
within one inch below the filler neck.  Do not overfill.
Use clean, fresh diesel fuel with a minimum cetane rating
of 40.

The in-line fuel filter (Figure 7-5) should be replaced
after every 500 hours of operation or annually, whichever
occurs first.

1. Close the shut-off valve.  Remove the two clamps

securing the fuel filter to the fuel hose.  Remove the
fuel filter.

2. Install a new fuel filter.  Be sure it is installed in the

proper direction.  Secure to the fuel hose using the
two clamps.

For any air cleaner, the operating environment dictates
the air cleaner service periods.  To make it convenient
for you we have installed an "Air Cleaner Indicator"
which is located just behind the air filter.  The indicator
window will turn red when it is time to service the air
filter.  Do not service the filter unless this indicator is red.

1. Snap open the two clips securing the air cleaner

cover to the air cleaner box.  Remove the air cleaner
cover, clean the duck bill vent of any dust and set the
cover aside.

2. Remove the air cleaner element and inspect.

3. Clean or replace the element as recommended by

the engine manufacturer.

4. Replace the air filter cover and be sure to snap the

two clips closed.

5. Reset the air cleaner indicator by pushing the button

on the end of the indicator.  The indicator window
should return to clear.
