MAINTENANCE
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 stays in a horizontal position and an unbalĆ
anced blade settles to the heavy side. If blade is
not balanced, file more metal off cutting edge on
heavy end of blade.
7.
Install blade driver hub, blade driver plate, sharp,
balanced LawnĆBoy blade, spacer, lockwasher, and
blade bolt. Sail part of blade must point toward top of
mower housing to ensure correct installation. Tighten
blade bolt to 60Ć80 N
m (45Ć60 ft-lb).
LUBRICATION
After every 25 operating hours or when season ends,
front and rear wheels must be lubricated.
1.
Apply 2 or 3 drops of light oil on inside and outĆ
side of all wheel bolts. Spin wheels to distribute oil
into bushings. Wipe up excess oil.
2.

fer to Draining Gasoline, page 11.
3.
Set mower to highest height-of-cut setting (E).
4.
Tip mower on its left side. Wipe grease fittings with
clean rag (Fig. 25). Install grease gun onto fitting and
gently apply one or two pumps of #2 Multi-Purpose
Lithium Base Grease.

CLEANING MOWER HOUSING
To ensure optimum performance, keep underside of
mower housing and inside of discharge area clean.
1.
Pull wire off spark plug. Drain gasoline from fuel
tank: refer to Draining Gasoline, page 11.
2.
Tip mower on its left side (Fig. 26). Avoid rotating
blade because starting problems may result.
3.
Remove dirt and grass clippings that stick to
housing by spraying it with a garden hose. Scrape
out remaining debris with hardwood scraper. Avoid
burrs and sharp edges.
4.
Clean discharge door and hinges of grass or deĆ
bris that may impair operation of door.

PREPARING MOWER FOR STORAGE
1.
For long term storage, it is recommended that
gasoline be drained from fuel tank or use a fuel addiĆ
tive before storing. To drain gasoline, refer to Draining
Gasoline, page 11. 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 stabilizer,
such as LawnĆBoy's 2+4
Fuel Conditioner, is added
to gasoline and run through engine before storing.
LawnĆBoy does not recommend stabilizers with an
alcohol base, such as ethanol or methanol. Use fuel
stabilizer in recommended quantities as specified on
container.
Under normal conditions, fuel additives remain effecĆ
tive in fuel for 6Ć8 months.
2.
Drain oil: refer to Changing Crankcase Oil,
page 12. After oil is drained, do not fill crankcase with
oil until the following steps (3-10) are completed.
3.
Remove spark plug and pour 30 ml (2 tableĆ
spoons) of SAE 30 oil into hole in cylinder. Pull starter
rope slowly to coat inside of cylinder. Install spark
plug and tighten to 20 N
m (15 ft-lb).
DO NOT
INSTALL WIRE ON SPARK PLUG.
