PROTECTION FOR CHILDREN
Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often
attracted to the machine and the mowing activity.
Never assume that children will remain where you last
saw them.
1. KEEP children out of the mowing area and under
the watchful care of a responsible adult.
2. DO NOT allow children in yard when machine is
operated (even with the blades OFF).
3. DO NOT allow children or others to ride on
machine, attachments, or towed equipment (even
with the blades OFF). They may fall and be
seriously injured.
4. DO NOT allow pre-teenage children to operate or
service the machine. Local regulations may
restrict the age of the operator.
5. ALLOW only adults or responsible teenagers with
mature judgment under close adult supervision to
operate machine.
6. DO NOT operate blades in reverse. STOP
BLADES. LOOK and SEE behind and down for
children, pets and hazards before and while
backing.
7. USE EXTRA CARE when approaching blind
corners, shrubs, trees, or other objects that may
obscure vision.
SLOPE OPERATION
1. Slopes are a major factor related to slip and fall
accidents, which can result in severe injury. All
slopes require extra caution and slow speed. If
you feel uneasy on a slope, DO NOT mow it.
2. Mow across slopes, never up and down. Exercise
extreme CAUTION when changing directions on
slopes. Practice operation of machine on slopes
with blades off.
3. Use extra care with grass catchers or other
attachments: these affect the handling and the
stability of the machine.
4. DO NOT use tow behind attachments on slopes.
5. AVOID uphill starts.
6. Turf conditions can affect the machine's stability.
DO NOT operate machine under any condition
where traction, steering or stability is doubtful.
7. Chose a low enough ground speed setting so that
you will not have to stop or shift on a slope. Tires
may lose traction on slopes even though the
brakes are functioning properly.
SLOPE OPERATION
(Continued From Previous Column)
8. Always keep the machine in gear when going down
slopes. DO NOT shift to neutral (or actuate the hydro
roll release) and coast down hill.
PREPARATION
1. Read, understand
and follow instructions and
warnings in this manual and on the machine, engine,
and attachments. Know the controls and the proper
use of the machine before starting. If the operators or
mechanics cannot read English, it is the owner's
responsibility to explain this material to them.
2. Only mature, responsible persons shall operate the
machine and only after proper instruction. The owner
is responsible for training the operators. Further, the
owner/operator can prevent and/or is responsible for
accidents or injuries occurring to themselves, other
people or property.
3. Data indicates that operators age 60 and above, are
involved in a large percentage of mower-related
injuries. These operators should evaluate their ability
to operate the mower safely enough to protect
themselves and others from serious injury.
4. Handle fuel with extra care. Fuels are flammable and
vapors are explosive. Use only an approved fuel
container. DO NOT remove fuel cap or add fuel with
engine running. Add fuel outdoors only with engine
stopped and cool. Clean spilled fuel from machine. DO
NOT smoke.
5. Practice operation of machine with BLADES OFF to
learn controls and develop skills.
6. Check the area to be mowed and remove all objects
such as toys, wire, rocks, limbs and other objects that
could cause injury if thrown by blade or interfere with
mowing.
7. Evaluate the terrain to determine what accessories and
attachments are needed to properly and safely perform
the job. Only use accessories and attachments
approved by SNAPPER.
8. Keep people and pets out of mowing area.
Immediately, STOP blades, STOP engine, and Stop
machine if anyone enters the area.
9. DO NOT operate machine unless all shields, deflectors,
switches, blade controls and other safety devices are
in place and functioning properly.

truck or trailer bed with a plastic liner. Always place
the containers on the ground away from the vehicle
before filling.
7. Remove gas-powered equipment from the vehicle or
trailer and refuel it on the ground. If this is not
possible, then refuel equipment using a portable
container, rather than a gasoline dispenser nozzle.
8. DO NOT start gas powered equipment in enclosed
vehicles or trailers.
9. Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until fueling is
complete. DO NOT use a nozzle lock-open device

__Knowing that dirt will
quickly ruin an engine,
", manufacturers equip their
engines with extremely
efficient air cleaners to
filter out the harmful dirt.
As the dirt parUcles are stopped,
they build up and begin to clog

after servicing to prevent unfiltered air from
entering the engine. Some servicing hints on
several common types are:
28
PRIMARY MAINTENANCE
Generally, wash foam-type filters
In a dishwashlng 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.
Air is also needed to keep
your engine cool. Dirt, dust
& debris build up to restrict
and clog cooling air Intake
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
l under dry, dusty conditions
for a thorough cleaning of
fins.
Failure to keep external
surfaces clean not only
presents fire hazards, but
causes overheating and
resulting engine damages
such as:
1. distorted valve guides
2. sticking valves
t ° o. 3. scuffed, scored
,,,. walls
4. overspeedlng
5. loss of power
6. complete failure of
engine.
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.
Be aware that fuel breaks
down in storage and forms
gummy compounds which
will block carburetor pass-
ages. Never use fuel more
than 3 months old. Drain
tank then run the engine out
of fuel before storing during
the off-season.
An engine must also have proper lubrication.
All engines use some oil. On 4-cycle engines,
CHECK OIL LEVEL BEFORE EACH START-UP.
Wipe area clean around the oll 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 oll to flow down the fill
tube to prevent a false full reading when the
level could actually be low and result In engine
damage.
29
PRIMARY MAINTENANCE
On 4-cyle engines with an oil level plug,
don't be fooled into 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 point of overflowing at the
top of the fill hole.
I
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
mlnutesl 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 o11.
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 a high
quality oil such as Snapper's small engine
formulated 4-cycle engine o11. Refer to the
engine owner's manual for oil details.
