2.7 ADJUSTING FRONT DECK BAFFLE
(Models with an “F” prefix in model number)
(Example: F
R215012)
The front of the cutting deck on these m odels has
been modified with an open area. This allows the
blade to have more direc t c ontact with the grass and
allows more air flow into deck chamber. The
adjustable baffle should be secured in the lowest
position when using a grass bag. T he baffle should
be secured in the highest position when mulching
grass.
NOTE: Under certain conditions, when mulching, some
grass may blow out from under front of baffle. This is
normal but, the amount of grass blowing out can be
reduced. Lower baffle slightly to reduce the amount of
grass blow out.
1. Stop engine. See WARNING above.
2. Loosen wing nuts that secure front deck baffle.
See Figure 2.8.
3. Lower the adjustable baffle to the lowest position
when using a grass bag. Raise the baffle to its
highest position when mulching grass. Take care to
keep the baffle’s lower edge par allel to the bottom of
the deck. See Figure 2.8.

4.4. BELT SERVICE
On self-propelled mowers, the engine belt transmits
power from engine to drive disc. The drive disc powers
the poly-v belt which engages the transmission that
powers the rear wheels. Should these belts becom e
worn, they could cause slippage which would impair
mower perform ance. The condition of the engine belt
and poly-v belt should be checked after every 25 hours
of mower operation.

manufacturers equip their
engine with extremely
efficient air cleaners to
filter out the harmful dirt.

your engine cool. Dirt, dust &
debris build up restricts and

screens and fins. Clean
screens and fins at frequent
intervals. The engine blower
housing and shrouds should
be removed at least once
each season or more often
under dry, dusty conditions
for a thorough cleaning of
fins.
Generally, wash foam-type filters in
a dishwashing detergent and water
solution. Rinse and wring dry, then
saturate with oil and squeeze out
excess. Failure to re-oil this type filter will ruin the engine.
Clean paper elements by tapping
lightly. Blowing with air will rupture
paper elements.
Use a flashlight to detect clogged
or torn paper elements – replace if
damaged in any way.
Dirt can also be
introduced into an engine
in dirty fuel from a
contaminated container.
Always use clean fresh
fuel from a clean
container to guard
against dirt, sludge and
water contamination.
Failure to keep external surfaces

hazards, but causes overheating

Drain tank then run
the engine out of fuel
before storing during

An engine must also have proper lubrication. All
engines use some oil. On 4-cycle engine,
CHECK OIL LEVEL BEFORE EACH START-UP.
Wipe area clean around the oil check plug or
dipstick opening to keep dirt from falling into
the engine when checking the oil. Always check
with the machine on a level surface. On engines
with dipstick, keep the level up to, but not over,
the FULL mark. When adding oil, allow time for
all of the oil to flow dow n the fill tube to prevent
a false full reading when the level could actually
be low and result in engine damage.

On 4-cycle engines with an oil
level plug, don’t be fooled onto
thinking the engine has
sufficient lubricating oil if you
can see “some” oil in the
opening – the level should
always be brought up to the
top of the fill hole.
PRIMARY MAINTENANCE
On 2-cycle engines, lubrication must be
provided by an exact mixture of gasoline
and 2-cycle air-cooled engine oil. A 2-cycle
engine that is mistakenly run on straight
gasoline will be ruined in less than 5
minutes! If you keep straight gasoline in
addition to pre-mixed 2-cycle engine fuel,
be sure the containers are clearly marked
to avoid mix-up.
Snapper 2-cycle engines require a 32 to 1
mixture of gasoline and BIA certified TC-W
oil such as Snapper’s 2-cycle engine oil.
Many of the 2-cycle engine oils on the
market today make fantastic claims, but for
the best performance and long engine life,
always use Snapper 2-cycle oil. Pre-mix the
fuel and always shake the container before
filling the tank.
Change oil at regular intervals using a high
quality oil such as Snapper’s small engine
formulated 4-cycle engine oil. Refer to the
