Poulan 271150 manual Engine, AIR Filter

NOTE: The original equipment battery on your tractor is maintenance free. Do not attempt to open or remove caps or covers. Adding or checking level of electrolyte is not necessary.

TO CLEAN BATTERY AND TERMINALS Corrosion and dirt on the battery and terminals can cause the battery to “leak” power.

1.Disconnect BLACK battery cable first then RED battery cable and remove battery from tractor.

2.Rinse the battery with plain water and dry.

3.Clean terminals and battery cable ends with wire brush until bright.

4.Coat terminals with grease or petro- leum jelly.

5.Reinstall battery (See “REPLACING BATTERY" in the SERVICE AND AD- JUSTMENTS section of this manual).

TRANSAXLE COOLING

Keep transaxle free from build-up of dirt and chaff which can restrict cooling.

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.

ENGINE

LUBRICATION

Only use high quality detergent oil rated with API service classification SF-SJ. Se- lect the oil’s SAE viscosity grade accord- ing to your expected operating tempera- ture.

SAE VISCOSITY GRADES

							SAE 30
			5W-30
F	-20	0			30 32 40		60	80	100
C	-30	-20		-10	0	10	20	30	40

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

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 every 25 hours of op- eration or at least once a year if the tractor is not used for 25 hours in one year. Check the crankcase oil level before start- ing 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

Determine temperature range expected before oil change. All oil must meet API service classification SF-SJ.

•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

fitting.

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.

7.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.

8.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.

CLEAN AIR SCREEN

Air screen must be kept free of dirt and chaff to prevent engine damage from overheating. Clean with a wire brush or compressed air to remove dirt and stub- born dried gum fibers.

AIR FILTER

Your engine will not run properly using a dirty air filter. Replace pre-cleaner after every 25 hours of operation or every season. Service paper cartridge every 100 hours of operation or every season, whichever occurs first.

Service air cleaner more often under dusty conditions.
