CUSTOMER RESPONSIBILITIES
BATTERY
Your tractor has a battery charging system which is suffi­
cient for normal use. However, periodic charging of the
battery with an automotive charger will extend its Tife.
' Keep battery and terminals clean.
• Keep battery bolts tight.
• Keep small vent holes open (See “CONNECT BAT­
TERY” in the Assembly section of this manual).
» Recharge at 6-10 amperes for 1 hour.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to "leak” power.
• Open battery box door.
• Disconnect BLACK battery cable first then RED bat­
tery cable and remove battery from tractor.
• Wash battery with solution of four tablespoons of
baking soda to one gallon of water. Be careful not to get
the soda solution into the cells.
• Rinse the battery with plain water and dry,
» Clean terminals and battery cable ends with wire brush
until bright,
• Coat terminals with grease or petroleum jelly
• Reinstall batte^ (See “CONNECT BATTERY” In the
Assembly section of this manual),
V-BELTS
Check V-belts for deterioration and wear after 100 hours of
operation and replace if necessary. The belts are not
adjustable. Replace belts If they begin to slip from wear,
TRANSAXLE COOLING
Keep Iransaxle free from build-up of dirt and chaff which
can restrict cooling.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SF or SG - Select the oil's SAE viscosity grade
according to your expected operating temperature,
SAE VISCOSITY GRADES
I I.....................I...........
'F -20* G" 30’ 32* ^0^ 60* 80’ 100’
"C -30* 20’ -IO» 0 ‘ 10* 20' 30- .10’
TEMPERATURE RANOE ANTiCiPATED BEFORE NEXT 0!L CHANGE
NOTE: Although multi-viscosity oils (5W30. 10W30 etc.)
improve starling 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/dipslick securely each time you check the oil level,
TO CHANGE ENGINE OIL (See Figs, 15 and'id)
Determine temperature range expected before oB change.
All oil must meet API service classification SFor SG
Be sure tractor is on level surface.
Oil will drain more freely when warm.
Catch oii In a suitable container.
Remove oil fill cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil,.
Remove drain plug..
After oii has drained completely, replace oil drain plug
and tighten securely.
Refill engine with oil through oil fill dipstick tube. Pour
slowly. Do not overfill. For approximate capacity see
"PRODUCT SPECIFICATIONS" on page 3 of this
manual.
Use gauge on oil fill cap/dipstick for checking level. Be
sure dipstick cap is tightened securely for accurate
reading. Keep oil at “FULL” line on dipstick,.
