IMPORTANT SAFETY INSTRUCTIONS

WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects that
can cause injury and damage! Failure to comply with the following SAFETY instructions could result in serious

injury or death to the operator or other persons. The owner of the machine must understand these instructions

and must allow only persons who understand these instructions to operate machine. Each person operating the

machine must be of sound mind and body and must not be under the influence of any substance, which might

impair vision, dexterity or judgment. If you have any questions pertaining to your machine which your dealer
cannot answer to your satisfaction, call or write the Customer Service Department at SNAPPER, McDonough,
Georgia 30253. Phone: [phone]).

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 or on attachments (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.

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.

10. Make sure all safety decals are clearly legible.

SECTION 3 - OPERATING INSTRUCTIONS

3.9 CUTTING HEIGHT ADJUSTMENT
(Fixed Decks)

Mower has three methods of adjusting cutting height:

1. Moving position of BLADE on cutter spindle shaft.

2. Moving position of CASTER WHEEL on support.

3. Moving position of MOWER DECK on power unit.

WARNING

DO NOT attempt any maintenance, adjustments or

service with the engine running. Stop engine. Stop

blades. Lock Traction Levers. Remove key.
Disconnect spark plug wires from spark plugs and

secure wires away from spark plugs. Engine and
components are HOT. Avoid serious burns, allow all

parts to cool before working on machine.

3.10. ADJUSTING CASTER WHEELS

The Caster Wheel Assembly has four (4) 1/2" and one

(1) 1/4" thick spacer. The 1/4" thick spacer always stays

on the stop side of the caster support tube. The 1/2"
thick spacers are used to adjust the cutting height. When

placed above or below Caster Support Tube, they raise

or lower cutting height in 1/2" increments, thus providing
a "Quick-Adjust" method. The deck mounting has to be
changed to correspond to the caster repositioning. Refer

to Section "ADJUSTING FIXED DECK ATTACHMENT".

3.11 ADJUSTING BLADE ON CUTTER

SPINDLE

To change cutting height of Blades, move the Spacers from
under the Cutter Housing to above the Cutter Housing

Pulley. Each Spacer moved above the Cutter Housing
Pulley will provide an additional 1/4" of cutting height. DO

NOT put any Spacers below Blade. See Figures 3.13 and

3.14.

3.12 ADJUSTING FIXED DECK ATTACHMENT

The mower deck has four different positions for attaching

it to the power unit. The lowest setting provides a cutting
height range of 1-1/2" to 2-1/2", the middle low cut is 2-

1/4" to 3-1/4", the middle high cut is 3" to 4", and highest
cut is 3-3/4" to 4-3/4". Make sure the spacers on the
caster wheels are moved up or down as shown to

correspond with the bolt )ositions to keep deck level.
Once a desired cutting height is reached, attach the

mower deck to the power unit by installing 3 bolts on
each side in selected height of cut holes. Tighten bolts to

70 to 80 foot pounds torque. See Illustration.

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

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.

PRIMARY MAINTENANCE

On 4-cyle engines with an oil level plug,

don't be footed into thinking the engine has
sufficient lubricating all If you can see "some"

oll In the opening - the level should always be
brought up to the point of
top of the fill hole.

@

Change all at regular Intervals using s a high

quality oll such as Snapper's small engine
formulated 4-cycle engine oil Refer to the
engine owner's manual for all details.

On 2-cyele 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 strelght

gasoline will be ruined in less than 5

mlnutosl If you keep straight gasoline In
addition to pre-mlxed 2-cycle engine fuel,

be sure the containers are clearly marked
to avoid mix-up.

Snapper 2-cyale engines require a 32 to 1
mixture of gasoline and BIA certified TC-W

oUsuch as Snapper's 2-cyele engine oil
Many of the 2-cyele engine oils on the

market today make fantasflc claims, but for

the best performance and long engine life,
always use Snapper 2-cycle oti. Premix

the fuel and always shake the container
before filling the tank.
