temperature.

NOTE: Although multi-viscosity
oil (5E30, 10W30,
etc.) improves starting in coldweather, these multi-vis-
cosity oils will result in increased oil consumption
when used above 32° F. Check your oil level more fre-
quently to avoid possibleengine damage from running
low on oil.
WHEELS
DO NOT oil or grease the wheel bearings. Viscous
lubricantswill attractdust and dirt that will shorten the
life of the self-lubricatingwheel bearings. If you feel
the wheels must be lubricated, use only a dry, silicone
type lubricantsparingly,
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,
