CUTTING BLADE
The blade may easily be removed for grinding or
replacement as follows:
1. Remove bolt and lock washer holding blade and
blade adapter to engine crankshaft.
2. Remove blade and blade adapter from engine
crankshaft.

Fuel and oil Ratio: Break-in: Mix % pint of oil per one
gallon of gasoline for first five hours ot operation.
Thereafter, mixture can be
V 2 pint of oil per gallon of
gasoline. Use SAE 30, MM or MS, or outboard oil and
regular gasoline. Mix and store fuel-oil mixture in a
clean, tight fuel container. Low grade white premium
or ethyl grades of gasoline are not to be used. White
marine gasoline is acceptable.
3. Remove two bolts, lock washers and nuts holding
blade to blade adapter (if necessary).
When sharpening blade, follow the original angle of
grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade will
cause excessive vibration when rotating at high speeds
and may cause damage to the mower.
To insure safe operation of your unit, ALL nuts and
bolts must be checked periodically for correct tightness.
CAUTION
Be sure fuel is fresh and remix by shak­
ing container prior to filling engine fuel
tank.
Fuel-Oil Mixture: Warranty void if multiviscosity (lOW-
30) oils are used. Use only SAE 30, outboard or two-
cycle oil with regular grade gasoline.
Deck — The underside of mower deck should be
cleaned after each period of use as grass clippings,
leaves, dirt and other matter will accumulate. This ac­
cumulation of grass clippings, etc., is undesirable as it
will invite rust and corrosion and may cause an uneven
discharge of grass clippings at the next cutting.
The deck may be cleaned by tilting the mower forward
or on its side and scraping clean with a suitable tool
or by washing with a stream of water from a garden
hose.
4-CYCLE ENGINE
Change oil after first 5 hours of operation while engine
is warm. Thereafter, change oil every 25 hours of op­
eration while engine is warm. Engine may be drained
through oil filler opening. Be sure to replace drain
plug and oil filler cap.
IMPORTANT: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any
kind of work on lawn mower.
Wheels— Wheel bearings are of self-lubricating Forti-
flex. They require no lubrication. If your unit is pro­
vided with optional ball bearing wheels, lubricate at
least once a season with light oil.
Protective Shield — The pivot points on the protective
shield should be lubricated periodically with light oil
‘.o prevent any rust or binding.
Chute Deflector — The torsion spring and pivot point
should be lubricated periodically with light oil to pre­
vent any rust or binding. Deflector must work freely.
Engine — Follow engine manual for lubrication in­
structions.
CAUTION
Do not direct the stream of water at a
hot engine as damage to the engine
may result.
STORAGE — The following steps should be taken to
prepare lawn mower for storage.
1. Clean and lubricate mower thoroughly as described
in the preceding instructions.
2. Refer to Engine Manual for correct engine storage
instructions.
3. Coat mower's cutting blade with chassis grease to
prevent rusting.
4. Place blocks under deck to raise tires clear of floor.
5. Store mower in a dry, clean area.
