1. Remove battery. Refer to Section “BATTERY

REMOVAL”.

2. Place battery in a well-ventilated area on a level

surface.

3. Using distilled water, refill cells as required to

cover cell plates of which can also be visualized

through the plastic battery case.

If YARD CRUISER is to be stored out of season on

its rear bumper, it is recommended the battery be

removed, charged and stored.

1. Remove battery. (Refer to Section “BATTERY

REMOVAL”).

2. Perform battery service.

3. Bring battery to full charge, if required.

4. Store battery in an area away from the YARD

CRUISER on a wood surface. DO NOT STORE

BATTERY ON A CONCRETE SURFACE.

4. With cell caps removed, connect battery charger

to battery terminals. Red to positive (+) terminal

and black to negative (-) terminal.

Section 4 - ADJUSTMENTS & REPAIR

IMPORTANT: 3/16” above cell plates is the recommended

4.5.5. BATTERY TESTING

level. DO NOT place anything in battery other than specified

electrolyte.

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.

8. Install battery into power unit. Connect over flow

tube.

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.

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. The

Battery Condition chart below 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.

4.5.6. NEW BATTERY PREPARATION

1. Remove battery from carton.

2. Place battery in a well ventilated area on a level

non-concrete surface.

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

DO NOT OVERFILL! DO NOT attempt to charge

battery while installed on the Yard Cruiser. DO NOT

use “BOOST” chargers on the battery.

For three (3) years from purchase date for the original purchaser's residential, non-commercial 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.

For ninety (90) days from purchase date for the original purchaser's commercial, rental, or other non-residential use,

SNAPPER, through any authorized SNAPPER dealer will replace, free of charge, any part or parts found upon

examination by the factory at McDonough, Georgia, to be defective 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

part 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

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.
