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

plug. Engine and components are HOT. Avoid serious

burns, allow sufficient time for all components to cool.

Wear heavy leather gloves when handling or working

around cutting blades. Blades are extremely sharp and can

cause severe injury.

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

Perform all maintenance as described in the “Service

Schedule” section of this manual.

Engine

Service the engine according to the engine owner’s manual.

Air Filter

Refer to the engine owner’s manual for service instructions.

Engine Oil

Refer to the engine owner’s manual for service instructions.

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.

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

plug. Engine and components are HOT. Avoid serious

burns, allow sufficient time for all components to cool.

Wear heavy leather gloves when handling or working

around cutting blades. Blades are extremely sharp and can

cause severe injury.

(D) Cone washer (concave side up)

(E) Capscrew

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.
