WARNING I
®c
To reduce the potential for any injury, comply with the following safety instructions. Failure to comply with
the instructions may result in personal injury.
SAFE OPERATION PRACTICES FOR WALK-BEHIND MOWERS
TRAINING
1. It is suggested that this manual be read in its
entirety before attempting to assemble or
operate this unit. Keep this manual in a safe
place for future reference and for ordering
replacement parts.
2. Your rotary mower is a precision piece of
power equipment, not a plaything. Therefore,
exercise extreme caution at ail times.
3. Read this Owner’s Manual carefully. Be
thoroughly familiar with the controls and the
proper use of the equipment.
4. Never allow children to operate a power
mower. Only persons well acquainted with
these rules of safe operation should be al
lowed to use your mower.
5. Keep the area of operation clear of all per
sons, particularly small children and pets.
Stop engine when they are in the vicinity of
your mower. Although the area of operation
should be completely cleared of foreign ob
jects, a small object may have been over
looked and could be accidently thrown by the
mower in any direction and cause injury.
PREPARATION
1. Thoroughly inspect the area where the equip
ment is to be used. Remove all stones, sticks,
wire, bones and other foreign objects which
could be picked up and thrown by the mower
in any direction and cause injury.
2. Do not operate equipment when barefoot or
wearing open sandals. Always wear substan
tial footwear.
3. Do not wear loose fitting clothing that could
get caught on the mower.
4. Check the fuel before starting the engine.
Gasoline is an extremely flammable fuel. Do
not fill the gasoline tank indoors, while the
engine is running, or while the engine is still
hot. Wipe off any spilled gasoline before start
ing the engine as it may cause a fire or explo
sion.
5. Disengage the self-propelled mechanism or
drive clutch on units so equipped before start
ing the engine.
6. Never attempt to make a wheel or cutting
height adjustment while the engine is run
ning.
7. Mow only in daylight or in good artificial light.
8. Never operate the equipment in wet grass.
Always be sure of your footing. Keep a firm
hold on the handle and walk, never run.
OPERATION
1. Do not change the engine governor settings
or overspeed the engine. Excessive engine
speeds are dangerous.
2. Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at
all times as the rotating blade can cause in
jury.
3. Stop the blade when crossing gravel drives,
walks or roads.
4. After striking a foreign object, stop the
engine, remove the wire from the spark plug,
and thoroughly inspect the mower for any
damage. Repair the damage before restarting
and operating the mower.
5. If the equipment should start to vibrate abnor
mally, stop the engine and check immediately
for the cause. Vibration is generally a warning
of trouble.
6. Stop the engine whenever you leave the
mower, before cleaning the mower housing,
and when making any repairs or inspections.
7. When cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and
keep the wire away from the plug to prevent
accidental starting.
8. Before attempting to unclog the mower or
discharge chute, stop the engine and be sure
the blade has stopped completely. The cut
ting blade continues to rotate for a few
seconds after the engine is shut off. Never
place any part of the body in the blade area un
til you are sure the blade has stopped rotating.
Disconnect the spark plug wire and keep the
wire away from the plug to prevent accidental
starting.
9. Do not run the engine indoors.
10. Shut the engine off and wait until the blade
comes to a complete stop before removing
the grass catcher or unclogging chute.
11. Mow across the face of slopes, never up-anddown. Exercise extreme caution when chang
ing direction on slopes. Do not mow ex
cessively steep slopes.
12. Always disconnect electric mowers (line
operated) before cleaning, repairing or ad
justing.
13. Never operate mower without proper guards,
plates or other safety protective devices in
place.
14. Keep washout ports and other mower-housing
service openings closed when mowing.
15. DO NOT OPERATE this mower with the chute
doors open, unless the complete grass catch
er is properly mounted on the mower.
MAINTENANCE AND STORAGE
1. Check the blade and engine mounting bolts at
frequent intervals for proper tightness.
2. Keep all nuts, bolts, and screws tight to be
sure the equipment is in safe working condi
tion.
3. Never store the equipment with gasoline in
the tank inside of a building where fumes may
reach an open flame or spark. Allow the
engine to cool before storing in any
enclosure.
4. To reduce fire hazard, keep the engine free of
grass, leaves, or excessive grease.
5. Check the grass catcher bag frequently for
wear or deterioration. For safety protection,
replace only with new bag meeting original
equipment specifications.

Page 12
1. Remove the large bolt and lock washer which
holds the blade and adapter to the engine
crankshaft. See figure 21.
FIGURE 21.
2. Remove the blade and adapter from the
crankshaft. Be careful not to lose the key on
the crankshaft.
3. If the blade or blade adapter needs replacing,
remove the two small bolts, lock washers and
nuts which hold the blade to the adapter.
■»
FIGURE 22.
C. Reassembly
Before reassembling the blade and the blade
adapter to the unit, lubricate the engine
crankshaft and the inner surface of the blade
adapter with light oil. Lubricating the bolt holes,
bolts and inner surface of the nuts with light oil is
also recommended. A 4 oz. plastic bottle of light
oil lubricant is available. Order part number
737-0170. Engine oii may also be used.
When replacing the biade, be sure to install the
blade with the side of the blade marked “Bottom”
(or with part number) facing the ground when the
mower is in the operating position. Make certain
key is in place on the crankshaft.
B. Sharpening
Remove the cutting blade by following the direc
tions of the preceding section.
When sharpening the 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 un
balanced blade will cause excessive vibration
when rotating at high speeds, may cause damage
to the mower and could break, causing personal
injury.
The blade can be tested for balance by balancing
it on a round shaft screwdriver. Remove metal
from the heavy side until it balances evenly. See
figure 22.
NOTE
It is recommended that the blade
always be removed from the adapter
for the best test of balance.
Blade Mounting Torque
3/8" Dia. Bolt 375 in. lb. min., 450 in. lb. max.
5/16" Dia. Bolt 150 in. lb. min., 250 in. lb. max.
To insure safe operation of your unit, ALL nuts
and bolts must be checked periodically for correct
tightness.
DECK
The underside of the mower deck should be
cleaned after each period of use as grass clip
pings, leaves, dirt and other matter will ac
cumulate. This accumulation of grass clippings,
etc., is undesirable as it wili invite rust and corro
sion and may cause an uneven discharge of grass
clippings at the next cutting.
The deck may be cleaned by tilting the mower for
ward or on its side and scraping clean with a
suitable tool or by washing with a stream of water
from a garden hose.
12
Page 13
CAUTION
OFF-SEASON STORAGE
Do not direct the stream of water at
a hot engine as damage to the
engine may result. Be sure spark
plug wire is disconnected.
ENGINE OIL
Check oil level before starting engine and after
every 5 hours of operation. Add oil as necessary to
keep level full to full mark on dipstick. Engine
should be in a level position when checking oil.
Change oil after first 5 hours of operation.
Thereafter change every 25 hours. Change oil
while engine is warm. Oil may be drained thru
drain on bottom of engine. To drain completely,
always place engine level when draining thru the
bottom. Oil capacity 1V4 pints. See figure 23.
Drain ^
Plug , ^
If the machine is to be inoperative for a period
longer than 30 days, the following procedures are
recommended:
1. Working outdoors, drain all fuel from the fuel
tank. Use a clean dry cloth to absorb the small
amount of fuel remaining in the tank. Then run
the engine until all fuel in the carburetor is ex
hausted.
Varn*ng*
Do not drain fuel while smoking, or
if near an open fire.
2. Drain all the oil from the crankcase (this
should be done after the engine has been
operated and is still warm). Refill the
crankcase with clean new oil.
3. Disconnect the spark plug wire and remove
the spark plug from the cylinder. Pour about 2
or 3 tablespoons of engine oil Into the
cylinder. Turn the engine over several times to
spread out the oil. Replace the spark plug, but
do not connect the wire.
4. Clean the engine and the entire mower
thoroughly.
5. Lubricate all lubrication points.
FIGURE 23.
AIR CLEANER
Service air cleaner every 25 hours under normal
conditions. Clean every few hours under extreme
ly dusty conditions. Poor engine performance and
flooding usually indicates that the air cleaner
should be serviced. To service the air cleaner,
refer to the engine manual packed with your unit.
SPARK PLUG
The spark plug should be cleaned and the gap
reset once a season. Spark plug replacement is
recommended at the start of each mowing
season; check engine manual for correct plug
type and gap specifications.
