ENGINE AND SNOWTHROWER MAINTENANCE

7.Slowly unscrew the drain plug. Allow the oil to run down the cardboard and into the container.

8.After the oil has drained, reinstall the drain plug and very securely tighten it.

9.Add clean oil to the engine. See "Checking Engine Oil Level and Adding Oil to Engine".

Engine Ignition System

The snowthrower engine has an electronic ignition system. This system eliminates the traditional set of points and condensor. The electronic ignition system also eliminates the yearly tune-up. The only sched- uled maintenance you need to perform on the engine'signition system concerns the spark plug (which is discussed next).

Spark Plug

Yearly, or every 100 hours of operation, remove the engine'sspark plug, clean it, and inspect it. Clean the spark plug by scraping it (don'twire brush it or sand blast it). Replace the spark plug with a new one if its electodes were pitted or burned, or if its por- celain was cracked.

Before installing the spark plug, set its electrode gap at 0.030 inch.

COMPLIANCE WITH RADIO INTERFERENCE REGULATIONS CERTI- FIED. REPLACE SPARK PLUG WITH RESISTOR

.030 (.8 mm) SPARK PLUG.

Carburetor Adjustment

Your carburetor has been set for proper operation. If you believe that it has come out of adjustment, please refer to the engine owner'smanual for the correct carburetor adjustment procedure.

SNOWTHROWER MAINTENANCE

Lubrication

Refer to Figure 5-4 and the numbered items follow- ing it to determine which areas on your snowthrower should be lubricated.

At the beginning and end of each snow throwing season, be sure to lubricate the snow thrower as recommended. This will help prevent any corrosion at

friction points during the off-season. It will also ensure that the snowthrower will be ready to use when the first snow falls.

1.Use clean engine oil or a silicone spray to lubri- cate the handlebar levers'pivot points. Be careful not to get any oil or silicone spray on the levers.

2.Clean any dirt off the toothed part of the flange on the bottom of the discharge chute. Apply fresh grease to the worm gear and toothed part of the flange.

3.Apply fresh engine oil to the bearing on each side of the auger shaft. Wipe off any excess oil.

4.Sparingly oil the discharge chute control crank where it enters the control panel. Also oil it at the support on top of the left hand rear side of the frame.

5.Sparingly apply oil to the two pivot points on the deflector cap.

6.One at a time, remove the wheels and apply fresh grease to the wheel shaft and clevis pin. This makes future wheel removal easier.

7.Check the auger gear box'sgear oil level. Move the snowthrower to a level area. Unscrew the plug (Figure 5-4, Item 7) from the front of the gear box. Oil should just begin to flow out of the hole. If it doesn't,add SAE 90 gear oil to the gear box. Fill the gear box until the oil just begins to flow from
