McCulloch MC30 manual Battery, Transaxle Cooling, Belt, Lubrication, To Change Engine OIL

BATTERY

Your riding mower has a battery charging system which is sufficient 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 electrolyte 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 adjustable. Replace belt if it begins to slip from wear.

LUBRICATION

Only use high quality detergent oil rated with API service classification SG-SL. Select the oil’s SAE viscosity grade according to your expected operating temperature.

				SAE 30
		5W-30
F	-20	0	30 32 40	60	80	100

TO CHANGE ENGINE OIL

Determine temperature range expected before oil change. All oil must meet API service classification SG-SL.

•Be sure riding mower is on level surface.

•Oil will drain more freely when warm.

•Catch oil in a suitable container.

CAUTION: If engine has been operated for an extended period of time immediately prior to draining oil, oil will be hot.

1.Lift engine cover.

2.Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil.

3.Position a container to catch oil.

4.Remove drain plug and drain oil into container.

5.After oil has drained completely, replace oil drain plug and tighten securely.

6.Refill engine with oil through oil fill dip- stick tube. Pour slowly. Do not overfill. For approximate capacity see “PROD- UCT SPECIFICATIONS” section of this manual.

7.Use gauge on oil fill cap/dipstick for checking level. For accurate reading, tighten dipstick cap securely onto the tube before removing dipstick. Keep oil at “FULL” line on dipstick. Tighten cap onto the tube securely when finished.

8.Lower engine cover.

TO START ENGINE WITH A WEAK BATTERY

CAUTION: Lead-acid batteries gener- ate explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection when around batteries.

If your battery is too weak to start the engine, it should be recharged. (See "BATTERY" in the Maintenance section of this manual).

REPLACING BATTERY

WARNING: Do not short battery termi- nals by allowing a wrench or any other object to contact both terminals at the same time. Before connecting battery, remove metal bracelets, wristwatch bands, rings, etc.

Positive terminal must be connected first to prevent sparking from accidental grounding.

1.Lift seat pan to raised position.

2.Remove terminal cover.

3.Disconnect BLACK battery cable then RED battery cable, battery strap and carefully remove battery from riding mower.

4.Install new battery with terminals in same position as old battery.

5.Reinstall terminal cover.

6.First connect RED battery cable to positive (+) battery terminal with bolt and nut as shown. Tighten securely.

7.Connect BLACK grounding cable to negative (-) battery terminal with remaining bolt and nut. Tighten securely

8.Lower seat pan.

INTERLOCKS AND RELAYS

Loose or damaged wiring may cause your riding mower to run poorly, stop running, or prevent it from starting.

•Check wiring. Ensure all wiring and con- nectors are secure.

ENGINE

Your carburetor is not adjustable. If your engine does not operate properly due to suspected carburetor problems, take your riding mower to a qualified service center for repair and/or adjustment.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting 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.
