(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

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.

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.

SAFETY OF SNAPPER PRODUCTS AND WILL VOID ANY LIABILITY AND WARRANTY BY SNAPPER ASSOCIATED
