BATTERY SERVICE 4.5.1.

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 with electrolyte to proper level. 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.

IMPORTANT: Never place anything in battery other than specified electrolyte.

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 to proper level.

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.

WARNING

DO NOT over fillbatterywith electrolyte.

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 charging battery or when handling electrolyte or battery. Electrolyte (acid) is a highly corrosive liquid.

Wear eye protection. Wash affected areas immediately after having eye or skin contact with electrolyte (acid).

Battery acid is corrosive. Rinse empty acid containers with water and mutilate before discarding.

If acid is spilled on battery. bench. or clothing. etc. Flush with clear water and neutralize with baking soda.

Never attempt to charge battery while installed on the walk behind. Never use "BOOST" chargers on the battery.

4.5.2.

BATTERY SERVICE 1. Remove battery.

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

3. Using distilled water. refill cells as required to bring fluid to proper level.

4. With cell caps removed. connect battery charger to battery terminals.

Red to positive (+) terminal and black to negative (-) terminal.

5. Stow charge battery at 1 amp for 10 hours.

6. If battery will not accept charge or is partially charged after 10 hours of charging at 1 amp. replace with new battery.

4.5.3.BATTERY STORAGE If Walk Behind is to be stored out of season on its rear bumper. it is recommended the battery be removed. charged and stored.

1. Remove battery.

Perform battery service.

3. Bring battery to full charge. if required.

4. Store battery in an area away from the Walk Behind on wood surface.

DO NOT STORE BATTERY ON A CONCRETE SURFACE.

4.5.4.

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 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.

The engine on your Snapper product spends Its entire life operating close to the ground at high speed creating a virtual storm of dust and dlrtl

PRIMARY MAINTENANCE

The engine must gul gallons of air for

As the dirt particles are stopped. they build up and begin to clog the outside of the filter. This reduces the amount of air available to the engine and causes an over-rich fuel mixture which re sults In the following adverse effects:

An Improperly serviced. dirt clogged air cleaner wllh

Increase fuel consumption cause power loss result in hard starting create smoke from unburned fuel produce carbon build-up

Internally

Damage caused by a poorly serviced air cleaner is not covered under the engine warranties.

So. save yourself unnecessary expenses and undue aggravation by keeping the air cleaner properly serviced at the intervals specified In the engine owner's manual•

It doesn't take long to service an air cleaner• Follow the specific instructions In the engine owner's manual for the type filter used. Pre vent dirt from falling Into the carburetor Intake when servicing your air cleaner. Make sure components are Installed in correct sequence after servicing to prevent unfiltered air from entering the engine.

Some servicing hints on several common types are:

PRIMARY MAINTENANCE

Generally. wash foam-type filters In a dlshwashlng detergent and water solution.

Rinse and wring dry. then saturate with oil and squeeze out excess.

Failure to re-oil this type filter will ruin the engine.

Clean paper elements by tapping lightly. Blowing with air will rupture paper elements.

Failure to keep external surfaces clean not only presents fire hazards. but causes overheating and resulting engine damages such as:

1. distorted valve guides valves t ° o. 3. scuffed. walls 4. overspeedlng 5. loss of power 6. complete failure of engine.

Dirt can also be Introduced into an engine In dirty fuel from a contaminated container.

Always use clean fresh fuel from a clean container to guard against dirt. sludge and water Ion.

An engine must also have proper lubrication.

All engines use some o11.On 4-cycle engines.

CHECK OIL LEVEL BEFORE EACH START-UP.

Wipe area clean around the oll check plug or dipstick opening to keep dirt from falling into the engine when checking the o11. Always check Nlththe machine on a level surface.

On engines with dipstick. keep the level up to. but not over. the FULL mark. When adding o11. allow time for all of the oll to flow down the fill tube to prevent a false full reading when the level could actually be low and result In engine damage.
