11. STOP engine immediately after striking an
obstruction. Inspect machine and repair damage
before resuming operation.
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.
15. DO NOT operate engine in enclosed areas. Engine
exhaust gases contain carbon monoxide, a deadly
poison.
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.
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

clothing, etc., Flush with clear water and neutralize
with baking soda.
1. Remove battery retainer.
2. Slide battery from battery box to gain
access to terminal cables.
3. Observe and note cable positions on
battery. See Figure 4.10.
4. Disconnect cables from battery terminals,
disconnecting BLACK (Negative) cable first,
then disconnect RED (Positive) last. Retain
mounting bolts and nuts.
WARNING
Cables must be connected to battery terminals in the
proper position. RED (Positive) cable must go to the
( + ) terminal. BLACK (Negative) cable must go to the
( - ) terminal.
4.7.3. BATTERY SERVICE

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.
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.
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.
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.
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.
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.
WARNING
DO NOT OVERFILL!

2 YEAR LIMITED WARRANTY
For two (2) years from purchase date for the original purchaser's use, SNAPPER, through any authorized
SNAPPER dealer will replace, free of charge (except for taxes where applicable), any part or parts found upon
examination by the factory at McDonough, Georgia, to be defective in material or workmanship or both.
SNAPPER FIELD SERVICEABLE SPINDLES and their components used on SNAPPER PRO® Mid Size walks
and SNAPPERZRIDER® ride on commercial equipment have a three (3) year limited warranty against defects in
material or workmanship or both.
All transportation costs incurred by the purchaser in submitting material to an authorized SNAPPER dealer for
replacement under this warranty must be paid by the purchaser.
This warranty does not apply to engines and their components, and batteries, as these items are warranted
separately. This warranty does not apply to parts that have been damaged by accident, alteration, abuse,
improper lubrication, normal wear, or other cause beyond the control of SNAPPER. This warranty does not
cover any machine or component that has been altered or modified, changing safety, performance, or durability.
Batteries have a one (1) year prorated warranty period with free replacement if required during the first ninety
(90) days 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
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.
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.
