PROTECTION FOR CHILDREN

PROTECTION AGAINST TIPOVERS

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. Children who have been
given rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over by the
machine. Never assume that children will remain where you
lastsaw them.

(Continued From Previous Column)
5. STAY ALERT for holes and other hidden hazards. Tall
grass can hide obstacles. Keep away from ditches,
washouts, culverts,fences and protruding objects.
6. KEEP A SAFE DISTANCE (at least 3 feet) away from edge
of ditches and other drop offs. The machine could turn
over ifan edge caves in.
7. Always begin forward motion slowly and with caution.
8. Use weights or a weighted load carrier in accordance
with instructionssupplied with a grass catcher. DO NOT
operate machine on slopes exceeding 10 degrees (18%
grade) when equipped with grass catcher.
9. DO NOT put your foot on the ground to try to stabilizethe
machine.
10. DO NOT operate machine on wet grass. Reduced
traction could cause sliding.
11. Choose a low enough 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.
12. DO NOT operate machine under any condition where
traction,steering or stability is doubtful.
13. Always keep the machine in gear when going down
slopes. DO NOT shift to neutral (or actuate hydro roll
release) and coast downhill.

KEEP children out of the mowing area and under the
watchful care of a responsible adult other than the
operator.
DO NOT allow children in yard when machine is operated
(even with the blade OFF).
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.
DO NOT allow pre-teenage children to operate machine.
ALLOW only responsible adults & teenagers with mature
judgment under close adult supe_ision to operate
machine.
DO NOT operate blades in reverse. STOP BLADES.
LOOK and SEE behind and down for children, pets and
hazards before and while backing.
USE EXTRA CARE when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.

PROTECTION AGAINST TIPOVERS
Slopes are a majorfactor related to loss-of-controland tipover accidents, which can result in severe injuryor death. All
slopes requireextra CAUTION. Ifyou cannot back up the
slope or ifyou feel uneasy on the slope, DO NOT mow it. Use
extra care with grass catchers or other attachments; these
affect the handling and the stability of the machine.
1. DO NOT operate machine on slopes exceeding 15
degrees (27% grade).
2. Exercise EXTREME CAUTION on slopes above 10
degrees (18% grade). Turn blades OFF when traveling
uphill. Use a slow speed and avoid sudden or sharp
turns.
3.

DO NOT operate machine back and forth across face of
slopes. Operate up and down. Practice on slopes with
blades off.
AVOID starting, stopping or turning on slopes. If machine
stops going uphill or tires lose traction, turn blades OFF
and back slowly straight down the slope.

4.5.6. BATTERY TESTING
There are two types of battery tests: Unloaded and
Loaded. The unloaded test is the procedure that
will be discussed. It's the simplest and most
commonly used. An unloaded test is made on a
battery without discharging current. To perform
unloaded testing, check charge condition using
either a hydrometer or voltmeter.

WARNING
The electrolyte (acid) produces a highly explosive gas.
Keep all sparks, flame and fire away from area when
charging battery or when handling electrolyte or
battery. Electrolyte (acid) is a highly corrosive liquid.
Wear eye protection. Wash affected areas immediately
after having eye or skin contact with electrolyte (acid).
Battery acid is corrosive. Rinse empty acid containers
with water and mutilate before discarding. If acid is
spilled on battery, bench, or clothing, etc., Flush with
clear water and neutralize with baking soda. DO NOT
attempt to charge battery while installed on the
SCRAMBLER. DO NOT use "BOOST" chargers on the
battery.

1. Using a voltmeter, voltage readings appear
instantly to show the state of charge. Remember to
hook the positive lead to the battery's positive
terminal, and the negative lead to the negative
terminal.
2. A hydrometer measures the specific gravity of
each cell. The specific gravity tells the degree of
charge; generally, a specific gravity of about 1.265
to 1.280 indicates full charge. A reading of 1.230 to
1.260 indicates the battery should be charged. The
Battery Condition chart below shows the charge
level as measured by syringe float hydrometer,
digital voltmeter and five ball hydrometer.

IMPORTANT: DO NOT place anything in new battery
other than specified electrolyte.

WARNING

DO NOT OVERFILL! DO NOT attempt to charge_
battery while installed on the SCRAMBLER. DO NOT
use "BOOST" chargers on the battery.

4.6 MOTION CONTROL ADJUSTMENTS
4.6.1.
Neutral Adjustments
When the machine is on a flat level surface and motion
control levers are in their neutral or neutral lock
positions, there should be no machine movement.
If
movement is present, adjustment must be made to left
and/or right transmission control rods (located to the left
and right of the operator seat, under the control panels):
1. Remove the hair pin and washer securing the
rod fitting to the Motion Control Lever pivot bracket.
See Figure 4.15. Pull fitting end out from bracket.
2. Turn fitting clockwise one turn if machine moves
in reverse, or counterclockwise if machine moves
forward.
3. Replace fitting into hole, securing with washer
and hair pin.
4. Start the machine. With motion control levers
left in their neutral lock positions, disengage the
parking brake and check for movement.
If
movement is still present, repeat steps 1-4 until
movement ceases.
5. Repeat for other side if needed.

5. Slow charge the battery at 1 amp for 2 hours to
bring the battery to full charge.
6. After charging, check level of electrolyte and
add as needed to bring to proper level.
7. Reinstall cell caps.
8. Install battery into power unit. Connect over flow
tube.
9. Connect positive (+) cable (red) first, from wiring
harness to the positive terminal (+) on battery
using bolt and nut provided in hardware bag.
Connect negative (-) cable (black)last, to negative
terminal (-) on battery using bolt and nut. Apply a
small amount of grease over terminals to prevent
corrosion.

Shield the positive terminal with terminal
located on battery harness. This prevents
from touching the WARNING
positive terminal, which
cause sparks.

4.6.4. Tracking Adjustments
When both motion control levers are fully engaged in
forward drive, the machine should move in a straight
line.
If the machine tracks (veers) left or right, a
tracking adjustment must be made.
Each motion
control lever is equipped with a tracking adjustment
plate. See Figure 4.18. Moving the plate forward or
backward adjusts the machine's tracking:
1. If mower tracks to the left, loosen the two torx
screws on the left adjustment plate, slide plate
forward approximately 1/8", and retighten screws.
(If plate is already as far forward as it can go,
loosen the right plate and slide back 1/8".) Check
machine tracking and repeat as needed.
2. If mower tracks to the right, loosen the two torx
screws on the right adjustment plate, slide plate
forward approximately 1/8", and retighten screws.
(If plate is already as far forward as it can go,
loosen the left plate and slide back 1/8".) Check
machine tracking and repeat as needed.

Snapper uses the best available engines and components
in their products in order to
provide long, satisfactory
service. However, proper
care is essential In
prolonging engine life. Dirt

high speed creating a virtual
storm of dust and dirtl

_nowing

that dirt will

quickly ruin an engine,
manufacturers equip their
engines with extremely
efficient air cleaners to
filter out the harmful dirt.

gulp about
gallons of air for
every gallon of
used. Because of
its working environment, the air available
to your Snapper engine Is "
heavily saturated with airborne dirt particles.

As the dirt particles are stopped,
they build up and begin to clog
the outside of the filter. This
reduces the amount of air
available to the engine and causes
an over-rich fuel mixture which results In the following adverse
effects:

Damage caused by a poorly serviced air
cleaner is not covered under the engine
warranties. So, save yourself unnecessary
expenses and undue aggravation by keeping
the air cleaner properly serviced at the intervals
specified In the engine owner's manual.

10. COST YOU MONEY!

It doesn't take long to service an air cleaner•
Follow the specific instructions In the engine
owner's manual for the type filter used. Prevent dirt from falling Into the carburetor Intake
when sarviclng your air cleaner. Make sure
components are Installed In correct sequence
after servicing to prevent unfiltered air from
entering the engine. Some servicing hints on
several common types are:

PRIMARY MAINTENANCE
Air is also needed to keep
your engine cool. Dirt, dust
& debris build up to restrict

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 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.

Failure to keep external

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 passages. 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 englnes use some oli. On 4-cycle englnes,
CHECK OIL LEVEL BEFORE EACH START-UP.
Wlpe area clean around the oli check plug or
dlpstlck opening to keep dlrt from falllng Into
the englne when checklng the oli. Always
check wlth the machlne on a level surface.
On englnes wlth dlpstlck, keep the level up to,
but not over, the FULL mark. When addlng oli,
allow tlme for all of the oli to flow down the fill
tube to prevent a false full readlng when the
level could actually be low and result In englne
damage.

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
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.

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,

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.
