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 de te ri o ra tion. Through normal
use it will wear. If catcher needs replac-
ing, replace only with ap proved 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 fi lled 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 Pre mi um 1 Grease, Part No.
750369. Do not substitute.

LUBRICATION
Use only high quality detergent oil rated with
API service classifi cation SG–SL. Select the
oil's SAE viscosity grade according to your
expected operating temperature.
SAE VISCOSITY GRADES
5W-30
-20 0 30 32
F
C -30 -20 -10 0
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 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 start-
ing 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, 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.
SAE 30
40 100
60 80
10 20 30 40
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.
Container
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.
6. Stop adding oil when you reach the
FULL mark on the dipstick. Wait a
minute to allow oil to settle.
7. Continue adding small amounts of oil,
rechecking the dipstick until oil level
settles at FULL. DO NOT overfi ll, or
engine will smoke heavily from the
muffl er on startup.
8. Always be sure to retighten oil dipstick
before starting engine.
9. Re con nect spark plug wire to spark
plug.
AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air fi lter.
Replace the air fi lter cartridge every 100
hours of op er a tion or every season, which-
ev er occurs fi rst. Service air cleaner more
often under dusty conditions.
TO CLEAN AIR FILTER
1. Loosen screw and tilt cover to re move.
2. Carefully remove cartridge.
3. Clean by gently tapping on a fl at sur-
face. If very dirty, replace car tridge.
CAUTION: Pe tro leum solvents, such
as ker o sene, are not to be used to clean
car tridge. They may cause de te ri o ra tion
of the cartridge. Do not oil car tridge. Do
not use pres sur ized air to clean or dry
car tridge.
4. Install cartridge, then replace cover
making sure the tabs are aligned with
the slots in the back plate. Fasten
screw securely.
