IMPORTANT SAFETY INSTRUCTIONS  
PREPARATION  
(Continued From Previous Page)  
OPERATION  
(Continued From Previous Column)  
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 blades  
or interfere with mowing.  
12. Mow only in daylight or with good artificial light.  
13. Move motion control levers SLOWLY to maintain  
control during speed and directional changes.  
14. Exercise CAUTION when pulling loads. DO NOT  
pull loads greater than 300 pounds. Avoid jack  
knifing. DO NOT turn sharply.  
7. Keep people and pets out of mowing area.  
Immediately, STOP blades, STOP engine, and  
STOP machine if anyone enters the area.  
8. Check shields, deflectors, switches, blade controls  
and other safety devices frequently for proper  
operation and location.  
9. Make sure all safety decals are clearly legible.  
Replace if damaged.  
10. Protect yourself when mowing and wear safety  
glasses, long pants and substantial footwear.  
11. Know how to STOP blades and engine quickly in  
preparation for emergencies.  
12. Use extra care when loading or unloading the  
machine into a trailer or truck.  
13. 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.  
15. DO NOT operate engine in enclosed areas. Engine  
exhaust gases contain carbon monoxide, a deadly  
poison.  
MAINTENANCE  
1. DO NOT 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.  
OPERATION  
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. Engine 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. DO NOT work under machine without safety  
blocks.  
9. Service engine and make adjustments only

12. Mower blades are sharp and can cut. Wrap the  
blades or wear heavy leather gloves and use  
CAUTION when handling them.  
13. DO NOT 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.  
1. Mount and dismount machine from left side.  
2. Start engine from operator's seat, if possible. Make  
sure blades are OFF and parking brake is set.  
3. DO NOT leave machine with engine running. Stop  
engine. Stop blades. Set brake. Remove key.  
4. DO NOT operate machine unless properly seated  
with feet on feet rests or pedal(s).

3. Remove battery cell caps. Fill cells as  
required with electrolyte (purchased  
separately) to proper level. Fill to 3/16”  
above cell plates. Filling battery with  
electrolyte will bring the battery to 80%  
charged state.  
4. With cell caps removed, connect battery  
charger to battery terminals; RED to positive  
(+) and BLACK to negative (-) terminal.  
WARNING  
Shield the positive terminal with terminal cover  
located on battery harness. This prevents metal from  
touching the positive terminal, which could over  
heat battery and/or battery cable and cause sparks.  
DO NOT attempt to charge battery while installed on  
the Zero Turning Radius Mower. DO NOT use  
“BOOST” chargers on the battery.  
IMPORTANT: 3/16” above cell plates is the recommended  
level. DO NOT place anything in battery other than specified  
electrolyte.  
4.7.4. BATTERY TESTING  
There are two types of battery tests:  
Unloaded and Loaded. The unloaded test is  
the procedure that will be discussed. It’s the  
simplest and most commonly used. An  
unloaded test is made on a battery without  
discharging current. To perform unloaded  
testing, check charge condition using either  
a hydrometer or voltmeter.  
5. Slow charge the battery at 1 amp for 2  
hours to bring the battery to full charge.  
6. After charging, check level of electrolyte  
and add as needed to bring level to 3/16”  
above cell plates.  
7. Reinstall cell caps.  
1. Using a voltmeter, voltage readings  
appear instantly to show the state of  
charge. Remember to hook the positive  
lead to the battery’s positive terminal, and  
the negative lead to the negative terminal.  
2. A hydrometer measures the specific  
gravity of each cell. The specific gravity tells  
the degree of charge; generally, a specific  
gravity of about 1.265 to 1.280 indicates full  
charge. A reading of 1.230 to 1.260  
indicates the battery should be charged  
before testing. The chart on the next page  
shows the charge level as measured by  
syringe float hydrometer, digital voltmeter  
and five ball hydrometer.  
8. Install battery into power unit.  
9. Connect positive (+) cable (red) first,  
from wiring harness to the positive terminal  
(+) on battery using bolt and nut provided  
in hardware bag. Connect negative (-)  
cable (black) last, to negative terminal (-)  
on battery using bolt and nut. Apply a small  
amount of grease over terminals to prevent  
corrosion.  
4.7.5. NEW BATTERY PREPARATION  
1. Remove battery from carton.  
2. Place battery in a well ventilated area on a  
level non-concrete surface.

Implied warranties, including those of merchantability and fitness for a particular purpose, are limited to  
two (2) years from purchase date for the original purchaser's use, and up to the extent permitted by law  
and all implied warranties are excluded. This is the exclusive remedy. Liabilities for consequential  
damages, under any and all warranties are excluded.  
Some states do not allow limitations on how long an implied warranty lasts, or do not allow the  
exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may  
not apply to you.  
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
