Craftsman 917.388732 owner manual cause eventual damage to lawn mower or engine

TO SHARPEN BLADE

NOTE: We do not recommend sharpen- ing 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 gdnding 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.

GRASS CATCHER

•The grass catcher may be hosed with water, but must be dry when used.

•Check your grass catcher often for damage or detedoration. Through normal use it will wear. If catcher needs replacing, replace only with a manufac-

turer approved replacement catcher. Give the lawn mower model number when ordering.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service classificationSF-SJ.

Select the oil'sSAE viscosity grade according to your expected operating temperature.

I__EtSAE VISCONTY GRADES

NOTE: Although multi-viscesityoils (5W30, 10W30 etc.) improve starting in cold weather, these muifi-viscesity 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.

TO CHANGE ENGINE OIL

NOTE: Before tipping lawn mower to

drain oil, drain fuel tank by running engine until fuel tank is empty.

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

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

3.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.

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

5.Fill engine with oil. (See =ADD OIL" in the Operation section of this manual}.

6.Reconnect spark plug wire to spark plug,
