GRASS CATCHER

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

•Check your grass catcher often for damage or deterioration. Through normal use it will wear. If catcher needs replacing, replace only with a manufacturer approved replacement catcher. Give the lawn mower model

number when ordering.

DRIVE WHEELS

Check front drive wheels each time before you mow to be sure they move freely.

The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free

drive wheels.

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°1:. 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

If necessary to clean the drive wheels, check both front wheels.

1.Remove hubcaps, hairpin cotters and washers.

2.Remove wheels from wheel adjusters.

3.Remove any trash or grass cuttings from inside the dust cover, pinion and/ or drive wheel gear teeth.

4.Put wheels back in place.

NOTE: If after cleaning, the drive wheels do not turn freely, contact a Sears or other qualified service center.

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 Texaco

Starplex Premium 1 Grease, Part No. 750369. Do not substitute.

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 where 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 Operacion section of this manual.)

6.Reconnect spark plug wire to spark plug.
