ing any maintenance,

TIRES

•Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause

tire damage.

TRIMMER LINE

For best results, replace trimmer lines when they have worn to half their original length. Use .155 inch diameter trimmer line. Cut new trimmer line length to 18-3/4 inches, After new line is installed on trimmer head, check all lines so they do not vary more then one (1) inch in length.

This is important to make sure the trimmer head is balanced and will not vibrate

abnormally.

_,WARNING: Use only the specified trimmer line. Do not use other materials

such as wire, string, rope, etc. Wire can break off during trimming and become a dangerous missile that can cause serious injury.

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

2.Hemove worn trimmer line from line carrier plate.

3.Fold new, cut to length, trimmer line in half and insert folded end through carrier plate opening to back side of retainer clip.

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

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.
