MAINTENANCE

Disconnect spark plug wire before performing any maintenance (except carburetor adjustment) to prevent accidental starting of engine.

Prevent fires! Keep the engine free of grass, leaves, spilled oil, or fuel. Remove fuel from tank before tipping unit for maintenance. Clean muffler area of all grass, dirt, and debris.

Do not touch hot muffler or cylinder fins as contact may cause burns.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service classification SF-SJ. Select the oil’s SAE viscosity grade according to your expected temperature.

FIG. 16

NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 40°F (4°C). 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 tiller is not used for 25 hours in one year.

Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Add SAE 30 motor oil or equivalent. Tighten oil filler plug securely each time you check the oil level.

TO CHANGE ENGINE OIL (See Figs. 16 and 17)

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

•Be sure tiller is on level surface.

•Oil will drain more freely when warm.

•Use a funnel to prevent oil spill on tiller, and catch oil in a suitable container.

•Remove drain plug. For easier removal of plug use 7/16 12 Pt. socket with extension.)

•Tip tiller forward to drain oil.

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

•Remove oil filler plug. Be careful not to allow dirt to enter the engine.

•Refill engine with oil. See“CHECK ENGINE OIL LEVEL” in the Operation section of this manual.

MUFFLER

Do not operate tiller without muffler. Do not tamper with exhaust system.Damaged mufflers or spark arresters could create a fire hazard. Inspect periodically and replace if necessary. If your engine is equipped with a spark arrester screen assembly, remove every 50 hours for cleaning and inspection. Replace if damaged.

SPARK PLUG

Replace spark plugs at the beginning of each tilling sea- son or after every 50 hours of use, whichever comes first. Spark plug type and gap setting is shown in “PRODUCT SPECIFICATIONS” on page 3 of this manual.

TRANSMISSION

Once a season, lubricate the right hand side gear case grease fitting with 1 oz. of EP #1 Grease.

CLEANING

Do not clean your tiller when the engine and transmission are hot. We do not recommend using pressurized water (garden hose, etc.) to clean your unit unless the gasket area around the transmission and the engine muffler, air filter and carburetor are covered to keep water out. Water in engine will shorten the useful life of your tiller.

•Clean engine, wheels, finish, etc. of all foreign mat- ter.

•Keep finished surfaces and wheels free of all gasoline, oil, etc.

•Protect painted surfaces with automotive type wax.
