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: (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 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 others to ride on 
machine or on attachments (even with the blades 
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.  DO NOT operate blades in reverse. STOP BLADES. 
LOOK and SEE behind and down for children, pets 
and hazards before and while backing. 
7. 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.  
1.  DO NOT operate machine on slopes exceeding 15 
degrees (27% grade). 
2.  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.  
3.  DO NOT operate machine back and forth across 
face of slopes. Operate up and down. Practice on 
slopes with blades off. 
4.  AVOID uphill starts. If machine stops going uphill 
or tires lose traction, turn blades OFF and back 
slowly down the slope.  
PROTECTION AGAINST TIPOVERS  
(Continued From Previous Column) 
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 
machine could turn over if an edge caves in.  
7.  Always begin forward motion slowly and with 
caution. 
8.  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. 
9.  DO NOT put your foot on the ground to try to 
stabilize the machine.  
10. DO NOT operate machine on wet grass. Reduced 
traction could cause sliding.  
11. DO NOT operate machine under any condition 
where traction, steering or stability is doubtful. 
PREPARATION 
1.  Read, understand, and follow instructions and 
warnings in this manual and on the machine, 
engine and attachments. Know the controls and 
the proper use of the machine 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 
from machine. DO NOT smoke.  
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 blade 
or interfere with mowing.

Section 2 - OPERATING INSTRUCTIONS 
2.6  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 blade running. To shift into reverse 
you must first stop the blade by releasing the blade 
pedals 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 blade running. As the Safety 
Instructions Indicate, DO NOT operate blades 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

13. Reinstall swivel and hair pin for deck support. 
 4.6.6. 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. 
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. The 
chart on the next page shows the charge level as 
measured by syringe float hydrometer, digital 
voltmeter and five ball hydrometer. 
WARNING 
Shield the positive terminal with terminal cover 
located on battery harness. This prevents metal from 
touching the positive terminal which could cause 
sparks.

from the original purchase date. SNAPPER will not be responsible for any installation cost incurred. The battery warranty 
only covers original equipment batteries and does not cover damage to the battery or machine caused by neglect or 
abuse, destruction by fire, explosion, freezing, overcharging, improper maintenance, or use of improper electrolyte. 
There is no other express warranty. 
 DISCLAIMER OF WARRANTY 
Implied warranties, including those of merchantability and fitness for a particular purpose, are limited to three 
(3) years from purchase date for the original purchaser's residential or other non-commercial use, and ninety 
(90) days from purchase for the original purchaser's commercial, rental or other non-residential use, and to the 
extent permitted by law, any 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. 
WARNING: THE USE OF REPLACEMENT PARTS OTHER THAN GENUINE SNAPPER PARTS MAY IMPAIR THE 
SAFETY OF SNAPPER PRODUCTS AND WILL VOID ANY LIABILITY AND WARRANTY BY SNAPPER 
ASSOCIATED WITH THE USE OF SUCH PARTS.
