Section 4 - REPAIR & ADJUSTMENTS
WARNING
DO NOT attempt any maintenance, adjustments or
service with engine and blade running. STOP engine
and blade. Disconnect spark plug wire and secure
away from spark plug. Engine and components are
HOT. Avoid serious burns, allow sufficient time for all
components to cool.
4.5. 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 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.
IMPORTANT: 3/16” above cell plates is the
recommended level. 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 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.
WARNING
DO NOT over fill battery with 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. DO NOT attempt to charge battery
while installed on the walk behind. DO NOT use
“BOOST” chargers on the battery.
4.5.2. BATTERY SERVICE
1. Remove battery.
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.
4. With cell caps removed, connect battery charger
to battery terminals. Red to positive (+) terminal and
black to negative (-) terminal.
5. Slow 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.
2. Perform battery service.
3. Bring battery to full charge, if required.
4. Store battery in an area away from the Walk
Behind on a 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 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
chart on the next page shows the charge level as
measured by syringe float hydrometer, digital
voltmeter and five ball hydrometer.
