Phone: (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. 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 last saw them.
- 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 supervision 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 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 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.
- DO NOT operate machine on slopes exceeding 15 degrees (27% grade).
- 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.
- 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.
- STAY ALERT for holes and other hidden hazards. Tall grass can hide obstacles. Keep away from ditches, washouts, culverts, fences and protruding objects.
- KEEP A SAFE DISTANCE (at least 3 feet) away from edge of ditches and other drop offs. The machine could turn over if an edge caves in.
- Always begin forward motion slowly and with caution.
- Use weights or a weighted load carrier in accordance with instructions supplied with a grass catcher. DO NOT operate machine on slopes exceeding 10 degrees (18% grade) when equipped with grass catcher.
- DO NOT put your foot on the ground to try to stabilize the machine.
- DO NOT operate machine on wet grass. Reduced traction could cause sliding.
- Chose 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.
- DO NOT operate machine under any condition where traction, steering or stability is doubtful.
- Always keep the machine in gear when going down slopes. DO NOT shift to neutral (or actuate hydro roll release) and coast downhill.

2.7. REVERSE LOCKOUT MECHANISM
Data indicates that tragic back-over accidents occur each year. These accidents usually involve unsupervised children. Many times these children have been given rides on the machine and have been trained to view this potentially dangerous piece of machinery as fun rather than being taught how to avoid danger.
This riding mower has a Reverse Lockout Mechanism. This mechanism prevents the mower from being shifted into reverse with the blades running. To shift into reverse you must first stop the blades and then shift to reverse. It is our recommendation that this mechanism remain functional and the operator of this equipment develop the habit of never backing up with the blades running. As the Safety Instructions Indicate, DO NOT operate blades with machine in reverse. STOP BLADES, LOOK AND SEE BEHIND AND DOWN for children, pets and hazards before and while backing.
We realize that this could cause a change to your previous mowing method but we encourage you to adjust to this new system. Do not defeat the Reverse Lockout Mechanism.
If you operate your mower near roadways or use attachments that require quicker shifting to reverse, there is an override lever provided. This lever can be pushed and held before engaging the blades and will allow reverse operation until the blade switch is pushed in to the “OFF” position, at which time the system will return to its Reverse Lockout mode. This feature should never be selected unless you are absolutely sure that no children or others are present in the mowing area and that all children are away and supervised by a responsible adult.
2.7.1. Reverse Lockout Mechanism Override
1. Stop machine. Stop blades.
2. Depress and hold Override Lever.
3. Pull blade switch “OUT” to engage blade.
4. Release Override Lever
WARNING
LOOK and SEE behind and down for children, pets and hazards before and while backing.
IMPORTANT! DO NOT use the Reverse Lockout Mechanism Override as the normal operating mode. To return to the Reverse Lockout Mechanism mode, disengage (STOP) blades by pushing blade switch in to the “OFF” position. The Override will reset to Reverse Lockout.
2.7.2. Check the Reverse Lockout Mechanism
Before each use, check the Reverse Lockout Mechanism for proper function. The following procedure requires the operation of the engine and blades. Before proceeding, Read, Understand, and Follow all Safety Instructions and Warnings in this manual and on the machine.
1. Complete Pre-Start Checklist.
2. Move machine to clear open area. DO NOT allow children or others in area.
3. Start engine.
4. Pull blade switch “OUT” to engage blades.
5. Reverse Lockout Mechanism must prevent speed control lever from going into reverse.
WARNING

PRIMARY MAINTENANCE
SNAPPER® vs. DIRT!
an illustration of how dirt can damage your engine & how reasonable maintenance can protect it!
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 is your engine’s enemy number 1!
The engine on your Snapper product spends its entire life operating close to the ground at high speed creating a virtual storm of dust and dirt!
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:
An improperly serviced, dirt clogged air cleaner will:
- increase fuel consumption
- cause power loss
- result in hard starting
- create smoke from unburned fuel
- produce carbon build-up internally
- foul spark plug electrodes
- score cylinder walls
- burn valves
- wear out the engine pre-maturely
- COST YOU MONEY!
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.
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 servicing 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:
Generally, wash foam-type filters in a dishwashing 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.
Clean paper elements by tapping lightly. Blowing with air will rupture paper elements.
Use a flashlight to detect clogged or torn paper elements - replace if damaged in any way.
Air is also needed to keep your engine cool. Dirt, dust & debris build up to restrict and clog cooling air intake 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.
Failure to keep external surfaces clean not only presents fire hazards, but causes overheating and resulting engine damages such as:
- distorted valve guides
- sticking valves
- scuffed, scored cylinder walls
- overspeeding
- loss of power
- complete failure of engine.
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 engines use some oil. On 4-cycle engines, CHECK OIL LEVEL BEFORE EACH START-UP. Wipe area clean around the oil 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 oil to flow down the fill tube to prevent a false full reading when the level could actually be low and result in engine damage.
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 oil. Refer to the engine owner’s manual for oil details.
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 minutes! 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 oil. 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.

Read and follow all safety instructions in safety booklets and manuals.
Keep in mind that dirt is your engine’s enemy #1 both internally and externally! internally, dirt will quickly ruin an engine and externally it will cause overheating and resulting internal .damages. Damage caused by improper lubrication, poor air cleaner service or overheating due to dirt cannot be covered under warranty.
It only takes a few moments to service the engine (and equipment) on a routine basis but the rewards will be a quick starting, responsive engine that will provide long satisfactory service with minimum maintenance cost. The prestart checklist in the next column and instructions in your Snapper Operator’s Manual are designated to help you keep your Snapper in top operating condition with minimum effort!
