TO SHARPEN BLADE

NOTE: We do not recommend sharpening blade - but if you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An unbalanced blade will cause

eventual damage to lawn mower or engine.

•The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower.

•To check blade balance, drive a nail into a beam or wall. Leave about one inch of

the straight nail exposed. Place center hole of blade over the head of the nail.

If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the

heavy end until the blade is balanced.

TEMPERATURE RANGE ANTK_PATEO BEFORE NE_T OIL CHANGE

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

cold weather, these multi--viscosityoils 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 lawn mower 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. Tighten oil plug securely each time you check the oil level.

•Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.

•Remove engine oil cap; lay aside on a clean surface.

•Tip lawn mower on its side as shown and drain oil into a suitable container. Rock lawn mower back and forth to

remove any oil trapped inside of engine.

•Wipe off any spilled oil on lawn mower and on side of engine.

•Fill engine with oil. Fill only to the "FULL"

line on the dipstick. DO NOT OVER FILL.
