ENGINE OIL RECOMMENDATIONS
A 20 ounce bottle of SAE 30 oil is included with your
new lawn mower
Only use high quality detergent oil rated with API ser-
vice classification
SG. Select the oil's viscosity grade
according to your expected operating temperature.
Colder -,_
32°F
_=- Warmer
5W30
[]
SAE 30
NOTE: Although
multi-viscosity
oil (5E30, 10W30,
etc.) improves starting in cold weather, these multi-
viscosity oils will result in increased oil consumption
when used above 32 ° F_ Check your oil level more
frequently to avoid possible engine damage from run-
ning low on oil
WHEELS
DO NOT oil or grease the wheel bearings_ Viscous
lubricants will attract dust and dirt that will shorten the
life of the self-lubricating
wheel bearings.
If you feel
the wheels must be lubricated, use only a dry, silicone
type lubricant sparingly_
WHEEL ADJUSTERS
For easy operation,
lubricate the wheel adjusters
at
least once a season with light oil.
BRAKE SPRING BRACKET
Spray a light oil lubricant on the brake spring bracket,
located on the right rear corner of the engine, at least
once a season.
TRANSMISSION
The transmission
is pre-lubricated
and sealed at the
factory. It does not require checking. If disassembled
for any reason, fill with 2 ounces of Alvania grease,
part number 737-0168.
