LUBRICATION
Blade Control
Lubricate pivot points on the blade control at least once a season with light oil. This
control must operate freely in both directions. See Figure 12.
Blade Care
When removing the cutting blade for sharpening or replacement, protect
your hands with a pair of heavy gloves or use a heavy rag to hold the blade.
Periodically inspect the blade adapter for cracks, especially if you strike a foreign
object. Replace when necessary. Follow the steps below for blade service.
1.
Disconnect spark plug boot from spark plug. Turn mower on its side making
sure that the air filter and the carburetor are facing up.
2.
Remove the bolt and the blade bell support which hold the blade and the
blade adapter to the engine crankshaft. See Figure 22.

Blade Bell Support
3.
Remove blade and adapter from the crankshaft.
4.
Remove blade from the adapter for testing balance. Balance the blade on a
round shaft screwdriver to check. Remove metal from the heavy side until
it balances evenly. When sharpening the blade, follow the original angle of
grind. Grind each cutting edge equally to keep the blade balanced.
An unbalanced blade will cause excessive vibration when rotating at high
speeds. It may cause damage to mower and could break causing personal
injury.
5.
Lubricate the engine crankshaft and the inner surface of the blade adapter
with light oil. Slide the blade adapter onto the engine crankshaft. Place the
blade on the adapter such that the side of the blade marked "Bottom" (or
with part number) faces the ground when the mower is in the operating
position. Make sure that the blade is aligned and seated on the blade adapter
flanges. See Figure 22 inset.

6.
Place blade bell support on the blade. Align notches on the blade bell
support with small holes in blade.
7.
Replace hex bolt and tighten hex bolt to torque: 450 in. lbs. min., 600 in. lbs.
max.
To ensure safe operation of your mower, periodically check the blade bolt for correct
torque.
Storage
Failure to use a fuel stabilizing additive such as
run the engine until it's out of fuel before off-season storage may result
in damage to your engine's carburetor. Subsequent damage would
covered under the manufacturer's warranty.
Gasoline that will be stored longer than 30 days needs to be pre-treated upon
purchase with fuel stabilizer such as
forming in the engines fuel and intake system. Improper fuel storage can result in
hard starting, no starting, stalling and poor performance. If the gasoline in your
engine deteriorates during storage, you may need to have the carburetor, and other
fuel system components, serviced or replaced.
1.
Remove all fuel from tank by running engine until it stops from lack of fuel.
Never leave engine unattended while running.
2.
Change oil. See Oil Change section.
3.
Remove spark plug and pour about 1/2 an ounce of engine oil into cylinder.
Replace spark plug and crank slowly to distribute oil.
4.
Clean debris from around engine, under finger guard, and under, around and
behind muffler. Touch up any damaged paint, and coat other areas that may
rust with a light film of oil.
5.
Do not use a pressure washer or garden hose to clean your unit.
6.
Coat mower's cutting blade with chassis grease to prevent rusting.
7.
Store in a clean, dry and well ventilated area away from any appliance that
operates with a flame or pilot light, such as a furnace, water heater, or
clothes dryer. Also avoid any area with a spark producing electric motor, or
where power tools are operated.
8.
If possible, also avoid storage areas with high humidity, because that
promotes rust and corrosion.
9.
Keep the engine level in storage. Tilting can cause fuel or oil leakage.
Removing From Storage
1.
If the fuel was drained during storage preparation, fill the tank with fresh
gasoline. If you keep a container of gasoline for refueling, make certain
it contains only fresh fuel. Gasoline oxidizes and deteriorates over time,
causing hard starting.
2.
If the cylinder was coated with oil during storage preparation, the engine
will smoke briefly at startup. This is normal.
