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 blade OFF).

3. DO NOT allow children or other passengers to

ride on machine or on attachments (even with the
blade OFF). They may fall and be seriously

injured.

4. DO NOT allow pre-teenage children to operate

machine.

5. ALLOW only responsible adults & teenagers with

mature judgment under close adult supervision to
operate machine.

6. BE SURE the area is clear of others before

mowing and turn machine OFF if anyone enters
the area.

7. DO NOT mow in reverse unless absolutely

necessary. LOOK BEHIND and down for small

children before and when backing.

8. USE EXTRA CARE when approaching blind

corners, shrubs, trees, or other objects that may
obscure vision.

PROTECTION AGAINST TIPOVERS

Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe

injury or death. All slopes require extra CAUTION. If

you cannot back up the slope or if you feel uneasy on

it, DO NOT mow it. Use extra care with grass catchers
or other attachments; these can change 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 blade OFF when
traveling uphill. Use first speed and avoid sudden
or sharp turns.

3. DO NOT mow back and forth across face of

slopes. Mow up and down.

PROTECTION AGAINST TIPOVERS

(Continued From Previous Column)

4. AVOID uphill starts. If machine stops going uphill
or tires lose traction, turn blade OFF and back

slowly down the slope.

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

mower could turn over if an edge caves in.

7. Always begin forward motion in the #1 speed

position.

8. Use weights or a weighted load carrier in
accordance with instructions with a grass catcher

on slopes above 10 degrees (18% grade).

9. DO NOT put your foot on the ground to try to
stabilize the machine.

10. DO NOT mow on wet grass. Reduced traction
could cause sliding.

11. DO NOT mow under any condition where traction,
steering or stability is doubtful without first test

driving over the terrain with blade OFF.

PREPARATION

1. Read this manual, get to know where all controls
are located and practice how to use them before

starting for the first time, and at the beginning of
each season. Read and follow Warnings and

Instructions on engine and machine. Read and
follow operator's manual and instructions
furnished with attachments.

2. Only mature, responsible persons shall operate
the machine and only after proper instruction.

3. Handle fuel with extra care. Fuels are flammable
and vapors are explosive. Use only an approved

fuel container. Never 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.

4. Practice operation of machine with BLADE OFF to

learn controls and develop skills.

(Continued on Next Page}

IMPORTANT SAFETY INSTRUCTIONS

PREPARATION

(Continued From Previous Page)

5. 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.

6. Keep people and pets a safe distance from
machine.

7. Check shields, deflectors, switches, blade
controls and other safety devices frequently for

proper operation and location.

8. Make sure all safety decals are clearly legible.
Replace if damaged.

9. Protect yourself when mowing and wear safety
glasses, long pants and substantial footwear.

10. Know how to STOP blade and engine quickly in
preparation for emergencies.

11. Use extra care when loading or unloading the
machine into a trailer or truck.

12. Check grass catcher components frequently for
signs of wear or deterioration and replace as
needed to prevent injury from thrown objects
going through weak or worn spots.

OPERATION

1. Mount and dismount machine from left side.

2. Start engine from operator's seat, if possible.
Make sure blade is OFF and parking brake is set.

3. STOP blade, STOP engine, set parking brake and
remove key when leaving machine.

4. DO NOT operate machine unless properly seated

with feet on feet rests or pedal(s).

5. STOP BLADE and ENGINE and make sure blade
has stopped before removing grass catcher or

unclogging mower to prevent loss of fingers or
hand.

6. Blade must be OFF except when cutting grass.

Set blade in highest position when mowing over

rough ground.

7. Keep hands and feet away from rotating blade
underneath deck. NEVER place foot on ground

while BLADE is ON or machine is in motion.

8. Deflector or entire grass catcher must be in place.
NEVER point discharge at people, passing cars,

windows or doors.

9, Slow down before turning.

10. Watch out for traffic when near or crossing

roadways.

11. STOP engine immediately after striking an

obstruction. Inspect machine and repair damage

before resuming operation.

12. Mow only in daylight or with good artificial light.

13. Move joystick (if equipped) SLOWLY to maintain

control during speed and directional changes.

14. Exercise CAUTION when pulling loads. Limit

loads to those you can safely control and attach
loads to hitch plate as specified with SNAPPER

attachment instructions.

MAINTENANCE

1. Never store machine or fuel container inside
where fumes may reach an open flame, spark or

pilot light such as in a water heater, furnace,
clothes dryer or other gas appliance. Allow
engine to cool before storing machine in an

enclosure. Store fuel container out of the reach of
children in a well ventilated, unoccupied building.

2. Keep engine free of grass, leaves or excess
grease to reduce fire hazard and engine

overheating.

3. When draining fuel tank, drain fuel into an
approved container outdoors and away from open

flame.

4. Check brakes frequently; adjust, repair or replace
as needed.

5. Keep all bolts, nuts and screws properly tight.
Check that all cotter pins are in proper position.

6. Always provide adequate ventilation when
running engine indoors. Exhaust gases contain

carbon monoxide, an odorless and deadly
poison.

7. Disconnect negative (black) cable from battery
before performing maintenance or service.
Cranking engine could cause injury.

8. Never work under machine without safety blocks.

9. Service engine and make adjustments only when
engine is stopped. Remove spark plug wire(s)
from spark plug(s) and secure wire(s) away from

spark plug(s).

10. DO NOT change engine governor speed settings
or overspeed engine.

11. Lubricate machine at intervals specified in
manual to prevent controls from binding.

12. Mower blades are sharp and can cut. Wrap the
blades or wear heavy leather gloves and use

CAUTION when handling them.

13. NEVER test for spark by grounding spark plug
next to spark plug hole; spark plug could ignite
gas exiting engine.

14. Have machine serviced by an authorized
SNAPPER dealer at least once a year and have the
dealer install any new safety devices.

15. Use only genuine SNAPPER replacement parts to
assure that original standards are maintained.
