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.
If necessary to clean the drive wheels, be
sure to clean 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.

ENGINE

LUBRICATION

Use only high quality detergent oil rated
with API service classification SF-SJ.
Select the oil's SAE viscosity grade
according to your expected operating
temperature.

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.

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 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 Operation section of this manual.)

6. Reconnect spark plug wire to spark

plug.
