TO CLEAN BATTERY AND TERMINALS Corrosion and dirt on the battery and terminals can cause the battery to "leak" power. 1. Remove terminal guard. 2. Disconnect BLACK battery cable first then RED battery cable and remove battery from tractor. 3. Rinsethe battery with plain waterand dry. 4. Clean terminals and battery cable ends with wire brush until bright. 5. Coat terminals with grease or petroleum jelly. 6. Reinstall battery (See "REPLACING BATTERY" in the SERVICE AND AD- JUSTMENTS section of this manual). 3. Unlock drain valve by pushing inward slightly and turning counterclockwise. 4. To open, pull out on the drain valve. 5. After oil has drained completely, close and lock the drain valve by pushing inward and turning clockwise until the pin is in the locked position as shown. 6. Remove the drain tube and replace the cap onto the end of the drain valve. Oil Drain Valve Closed and Locked __ Drain TRANSAXLE COOLING Keep transaxle free from build-up of dirt and Tube chaff which can restrict cooling. V=BELTS Yellow Ca 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. ENGINE LUBRICATION Only use high quality detergent oil rated with API service classification SG-SL Selectthe oil's SAE viscosity grade according to your expected operating temperature. . Refill engine with oil through oil fill dipstick tube. Pour slowly. Do not overfill. For approximate capacity see "PRODUCT SPECI FICATIO NS" section ofthis manual. . Use gauge on oil fill cap/dipstick for checking level. Insert dipstick into the tube and rest the oil fill cap on the tube. Do not thread the cap onto the tube when taking reading. Keep oil at "FULL' line on dipstick. Tighten cap onto the tube securely when finished.

Check the crankcase oil level before starting the engine and after each eight (8) hours of operation. TO CHANGE ENGINE OIL Determine temperature range expected before oil change. All oil must meet API service classification SG-SL. • Be sure tractor is on level surface. • Oil will drain more freely when warm. • Catch oil in a suitable container. 1. Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil. 2. Remove yellow cap from end of drain valve and install the drain tube onto the dirty air filter.
