OPERATION

(Continued From Previous Column)

14. Exercise CAUTION when pulling loads. Limit loads

to those you can safely control and attach loads to

hitch plate as specified with SNAPPER attachment

instructions.

15. DO NOT operate engine in enclosed areas. Engine

exhaust gases contain carbon monoxide, a deadly

poison.

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.

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.

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. 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 when

over rough ground.

7. Keep hands and feet away from rotating blades

underneath deck. DO NOT place foot on ground

while BLADES are ON or machine is in motion.

8. DO NOT operate machine without entire grass

catcher or guards in place. DO NOT point

discharge at people, passing cars, windows or

doors.

10. DO NOT change engine governor speed settings or

overspeed engine.

11. Lubricate machine at intervals specified in manual

to prevent controls from binding.

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.

16. If battery is removed, DO NOT operate engine

without insulating Positive + battery cable terminal

with electrical tape, or sparking from battery cables

can result.

WARNING

Shield the positive terminal with terminal cover

located on battery harness. This prevents metal

from touching the positive terminal, which could

cause sparks.

The electrolyte (acid) produces a highly explosive gas.

Keep all sparks, flame and fire away from area when

DO NOT use “BOOST” chargers on the battery.

4.4.6. 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.

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

level. DO NOT place anything in battery other than specified

electrolyte.

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

Battery Condition chart below shows the charge

level as measured by syringe float hydrometer,

digital voltmeter and five ball hydrometer.

WARNING

DO NOT OVERFILL! DO NOT attempt to charge

battery while installed on the Yard Cruiser. DO NOT

use “BOOST” chargers on the battery.

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.

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.

3 YEAR LIMITED WARRANTY

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.
