Acid solution level in each battery cell shoutd be even
with bottoms of vent well& Add only distilled or iron free
water if necessary.
Do not overfiH,
=
Keep battery and terminals clean,.
-
Keep battery bolts tight,
o
Keep vent caps tight and small vent holes in caps open.
o
Recharge at 6 amperes for I hour..
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to "leak" power.
o
Open battery box door,.
Disconnect BLACK battery cable first then RED bat-
tery cable and remove battery from tractor_

NOTE:
Although multi-viscosity
oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity 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' the first two hours of operation and
every 25 hours thereafter' or at least once a year if the
tractor 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
TO CHANGE ENGINE OIL (See Fig& 13 and 14)
Determine temperature range expected before oil change.
All oil must meet API service classification SF or SG,
