Wipe up spilled gasoline immediately
and completely.
Model B23 is equipped with an inline fuel filter
between the fuel tank and the fuel pump (low pres-
sure fuel pump). Visually inspect the filter periodi-
cally, and replace the filter
every 400 hours
. Use

microns for replacement filter.

IMPORTANT:
Replace the fuel filter only in a clean
area where the fuel line and connections will not
be contaminated by dust and dirt.
1. Expand and slide clamps on either side of the
filter away from filter and pull fuel lines off filter.
2. Replace filter, making sure that the arrow on
the filter is aligned with the fuel flow through
the filter.
3. Verify that the fuel lines and clamps are se-
curely attached, and that no fuel leaks are
present.
Blade Overload Shear Bolts
NOTE:
Blade shear bolts are not used on belt-
driven decks.
On gear-driven decks, each cutting blade is keyed
to the blade hub by
two (2) shear bolts
(10-24 x
5/8 in. stainless steel machine screws). These
bolts are designed to shear and protect the blade
drive gearbox from damage if the blade encounters
a shock load.
