BATTERY

Your riding mower has a battery charging

sys tem which is suf fi cient for normal use.

• Keep battery and connectors clean.

• Only recharge battery with charger

approved for a 12V 6 amp. hour battery.

• Charging with any other charger or an

automotive style charger can cause per-

manent damage to the battery.

• Charge battery for 24 hours for a full

charge.

NOTE: The original equipment battery on

your riding mower is maintenance free. Do

not attempt to open or remove caps or cov-

ers. Adding or checking level of elec tro lyte

is not necessary.

WARNING: Do not jump start battery.

Permanent damage to the battery or personal

injury may occur.
TRANSAXLE COOLING
Keep transaxle free from build-up of dirt and

chaff which can restrict cooling.
V-BELT
Check V-belt for deterioration and wear after

100 hours of operation and replace if neces-

sary. The belt is not ad just able. Re place belt

if it begins to slip from wear.

NOTE: Al though multi-vis cos i ty oils (5W30,

10W30 etc.) im prove start ing in cold weather,

the oils will result in increased oil consumption

when used above 32°F. Check your engine

oil level more frequently to avoid possible

engine damage from running low on oil.

Change the oil after every 25 hours of

operation or at least once a year if the riding

mower is not used for 25 hours in one year.

Check the crankcase oil level before starting

the engine and after each eight (8) hours

of operation. Tighten oil fill cap/dipstick

securely each time you check the oil level.

before oil change. All oil must meet API

service classification SG-SL.
• Be sure riding mower is on level surface.

CAUTION: If engine has been operated

for an extended period of time immediately

prior to draining oil, oil will be hot.

2. Remove oil fill cap/dipstick. Be careful

not to allow dirt to enter the engine when
