Operator Safety
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, contact the Customer Service Department
(1-800-935-2967).
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 watch-
ful care of a responsible adult other than the operator.
2. DO NOT allow children in yard when machine is operated
and turn machine OFF if anyone enters the area.
3. DO NOT allow pre-teenage children to operate machine.
4. ALLOW only responsible adults & teenagers with mature
judgment under close adult supervision to operate machine.
5. DO NOT pull mower backwards unless absolutely necessary.
LOOK and SEE behind and down for children, pets and hazards
before and while backing.
6. 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. 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. DO NOT mow
steep slopes or other areas where stability or traction is in
doubt. Refer to the Slope Guide at the end of this manual.
3. Use extra care with grass catchers or other attachments;
these affect the handling and the stability of the machine.
Preparation
1. Read, understand, and follow instructions and warnings in
this manual and on the mower, engine and attachments. Know
the controls and the proper use of the mower before starting.
2. Only mature, responsible persons shall operate the machine
and only after proper instruction.
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
and oil from machine. DO NOT smoke.
Preparation
(Continued From Previous Column)
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. Also note
the location of holes, stumps, and other possible hazards.
6. Keep people and pets out of the mowing area. Immediately,
STOP Blade, Stop engine and Stop mower if anyone enters the
area.
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, a
dust mask, long pants, and substantial footwear. DO NOT mow
barefooted or with sandals.
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 torn spots.
Safe Handling of Gasoline
To avoid personal injury or property damage, use extreme care
in handling gasoline. Gasoline is extremely flammable and the
vapors are explosive.
1. Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
2. Use only an approved fuel container.
3. DO NOT remove fuel cap or add fuel with the engine
running. Allow the engine to cool before refueling.
4. DO NOT refuel the machine indoors.
5. DO NOT store the machine or fuel container inside where
there is an open flame, spark or pilot light such as on a water
heater or other appliances.
6. DO NOT fill fuel containers inside a vehicle or on a 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.

Maintenance - Introduction
To retain the quality of the mower, use genuine replacement
parts only. Contact a local dealer for parts and service assis-
tance. For the correct part or information for a particular
mower, always mention the model and serial number.
Service - After First 5 Hours
Change Engine Oil
1. Refer to the Engine Manual for proper oil specifications,
procedures and proper service intervals.
2. For the simplest/cleanest oil change, simply turn the
mower on its side to drain the oil, as shown. Drain the
oil through the dipstick tube (A, Figure 13) into a
container. Allow sufficient time for all the oil to drain.
Important: Drain the fuel tank before tipping the machine.
DO NOT tip the machine with the carburetor or spark plug
down. Oil from the crankcase will saturate the air filter and
cause the engine to be hard to start or not start at all. If
contamination does occur, the air filter will have to be
replaced.
3. Dispose of drain oil properly.
4. Fill the engine with oil as specified in the Engine Manual.
Do not overfill.
Check Grease Level in Transmission
1. Remove the transmission fill plug (A, Figure 14). Roll
the machine forward or backward while looking down
into the plug hole.
2. If liquid grease is not visible on the input gear (the small
gear below the plug hole), add an amount, to cover the
gear, of Snapper “00” grease.
Note:
Snapper “00” grease (Part No. 7029443) is available at
your Snapper dealer.
Note:
Do not spill grease or oil onto the surface of the drive
disc (A, Figure 15).
3. Reinstall the transmission plug.
4. Check the grease level after each 25 hours of operation.
Important: Drain the fuel tank before tipping the mower. DO
NOT tip the machine with the carburetor or spark plug down.
Oil from the crankcase will saturate the air filter and cause
the engine to be hard to start or not start at all. If
contamination does occur, the air filter will have to be
replaced.
Figure 13: Draining the engine oil
WARNING
DO NOT attempt any maintenance, adjustments or service
with engine and blade running. STOP engine and blade.
Disconnect spark plug wire and secure away from spark

Check Mower Blade
1. Disconnect the spark plug wire and secure the end away
from the plug.
2. Tilt the mower up on its rear wheels for access to the
blade cap screw (A, Figure 16). Do not tilt the mower
with the spark plug or carburetor down.
Important: Drain the fuel tank before tipping the mower. DO
NOT tip the machine with the carburetor or spark plug down.
Oil from the crankcase will saturate the air filter and cause
the engine to be hard to start or not start at all. If
contamination does occur, the air filter will have to be
replaced.
3. Check the torque of the blade cap screw. Recommended
torque should be 40 ft. lbs.
4. Check the blade for sharpness, wear and damage. Refer
to the Section entitled “Blade Wear Limits”.
Check Engine Drive Belt
1. Visually check the engine drive belt for cracking, fraying,
severed or exposed belt strands. If worn or damaged,
replace the belt before operating the mower.
Check Transmission Poly-V Belt
1. Visually check the poly-v belt for cracking, fraying, sev-
ered or exposed belt strands. If worn or damaged,
replace the belt before operating the mower.
Service - Periodic

Storage Procedure
Refer to the Engine Owner’s Manual for directions regarding
engine storage preparations. Prepare the mower for “end of
season” storage as follows:
1. Drain the fuel from the fuel tank and let the engine run
until all fuel is out of the carburetor.
2. Disconnect and remove the spark plug wire away from
the spark plug before any other preparations are made!
3. Tape all openings closed to prevent spraying water into
the exhaust or air intakes during washing.
4. Tilt the mower up on its rear wheels and thoroughly
clean the underside of the deck. Do not tilt the mower
with the spark plug or carburetor down. Scrape away
any accumulation of grass with a putty knife and/or
wire brush.
5. Lubricate all exposed metal with a light coating of oil to
prevent corrosion.
6. On self-propelled models, disconnect the transfer rod
clip and remove the ground speed control rod before
folding the handles.
7. Loosen the handle knobs. Carefully fold the handles
forward, “flexing” the control cables to prevent cable
damage.
8. Store the mower in a shed or other dry area, protected
from weather.

7. Check torque of blade retaining cap screw.
Recommended torque should be 40 ft. lbs.
Wheel Drive Control Adjustment
1. The wheel drive control is properly adjusted when there
is 1/16” to 1/8” clearance (G, Figure 21) between the
inside of the spring hook (E) and the inside of the clutch
cable eye (C) with the wheel drive control released.
2. To adjust, unhook the upper spring (D) from the cable
eye and rotate the spring in the direction required to
extend or shorten the spring length.
3. Rehook the upper spring to the cable eye and check
clearance. Repeat the procedure if required.
Note:
The vinyl spring cover (B) should be kept over the
spring at all times except for adjustments.
4. If the wheel drive control fails to return quickly to the
“OFF” position when released, check for binding at the
cable holdings located on the side of the right handle.
The upper clip should be located 2” below the upper
knob; the lower clip should be 4” above the lower knob.
The cable should slide freely with the clips installed at
these locations.
