TO SHARPEN BLADE

NOTE: We do not recommend sharpening the 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 mower or engine.

•The blade can be sharpened with a fi le 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.

GRASS CATCHER

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

•Check your grass catcher often for dam- age or deterioration. Through normal use it will wear. If catcher needs replac- ing, replace only with approved replace- ment catcher shown in the Repair Parts section of this manual. Give the lawn mower model number when ordering.

GEAR CASE

•To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season.

•The gear case is filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case.

•If lubricant is required, use only Elf Mul- tis EP00. Do not substitute.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

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 op- eration orat least once a year if the mower is not used for 25 hours in one year. Check the crankcase oil level before starting the engine and after each fi ve (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, empty fuel tank by running engine until fuel tank is empty.

1.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with 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 re- move any oil trapped inside of engine.

4.Wipe off any spilled oil from lawn mower or side of engine.

5.Slowly pour oil down the oil fi ll spout, stopping every few ounces to check the oil level with the dipstick.
