POTENTIAL HAZARD
A worn or damaged blade could break and
a piece of blade could be thrown in
operator's or bystander's direction.
WHAT CAN HAPPEN
A thrown piece of blade could cause serious
personal injury or death to operator or
bystanders.
HOW TO AVOID THE HAZARD
Inspect blade periodically for wear or
damage.
Replace a worn or damaged blade.
Note: For best performance, install new blade
before cutting season begins. During
the year, file down small nicks to
maintain the cutting edge.
7. SHARPENING BLADE—Using a file, sharpen
top side of blade (side facing mower housing)
and maintain original cutting angle (Fig. 24).
The blade will remain balanced if the same
amount of material is removed from both cutting
edges.
IMPORTANT: Check balance of blade by putting
it on a blade balancer. An inexpensive balancer
can be purchased at a hardware store. A balanced
blade will stay in a horizontal position and an
unbalanced blade will settle to the heavy side. If
the blade is not balanced, file more metal off
cutting edge on heavy end of blade.
8. Install sharp, balanced blade, lockwasher and
blade bolt. Sail part of blade must point toward
top of mower housing to assure correct
installation. Tighten the blade bolt to 50 ft–lb
(68 N m).

Lubrication

After every 25 operating hours or when season ends,
front and rear wheels must be lubricated.
All manuals and user guides at all-guides.com
1. Apply 2 or 3 drops of light oil on inside and
outside of all wheel bolts. Spin wheels to
distribute oil into bushings. Wipe up excess oil.
2. Move rear wheel height-of-cut levers to "2"
setting. Wipe grease fittings with clean rag.
Install grease gun onto fitting and gently apply
two or three pumps of #2 Multi–Purpose
Lithium Base Grease (Fig. 25). Excess pressure
may damage seals and prevent the free wheel
clutch from operating properly.

Cleaning

To ensure best performance, keep underside of mower
housing clean.
1. Stop engine and pull wire off spark plug (Fig. 9).
2. Drain gasoline from fuel tank. See Drain
Gasoline section.
3. Tip mower on its left side (Fig. 26).
4. Remove dirt and grass clippings with a
hardwood scraper. Avoid burrs and sharp edges.
5. Turn mower upright.
6. Refill gas tank.
7. Reconnect spark plug wire.

Storage

1. For long term storage, it is recommended that
gasoline be drained from fuel tank or use a fuel
additive before storing. To drain gasoline, refer
to Drain Gasoline, page 12. After fuel is drained,
start engine and let it idle until all fuel is
consumed and engine stops. If gasoline is not
drained, gum–like varnish deposits will form and
cause poor engine operation or even starting
problems.
Fuel can be left in gas tank only if a fuel
additive, such as Toro's Stabilizer/Conditioner, is
added to gasoline and run through engine before
storing. Toro's Stabilizer/Conditioner is a
EN–15
