Operator's Manual
String Mower M220
Slope Operation
Slopes are a major factor related to slip and fall accidents
which can result in severe injury. All slopes require extra
caution. If you feel uneasy on a slope, do not mow it. Do mow
across the face of slopes; never up and down. Do not mow
excessively steep slopes (maximum 15 degrees) or areas
where the ground is very rough. See the“Slope Guide”in the
back of this manual to check a slope. Exercise extreme caution
when changing direction on slopes.
Remove objects such as rocks, tree limbs, etc.
Watch for holes, ruts, or bumps. Tall grass can hide obstacles.
IMPORTANT NOTES:
Do not mow near drop-os, ditches, or
embankments. The operator could lose footing or
balance.
Do not mow excessively steep slopes.
Do not mow on wet grass. Reduced footing could
cause slipping.
Children
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
mower and the mowing activity. Never assume that children
will remain where you last saw them.
• Keep children out of the mowing area and under the
watchful care of a responsible adult.
• Be alert and turn mower o if children enter the area.
• Before and while moving backwards, look behind and
down for small children.
• Never allow children to operate the mower.
• Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
Service
• Use extra care in handling gasoline and other fuels.
They are ammable and vapors are explosive.
• Use only an approved container.
• Never remove gas cap or add fuel with the engine
running. Allow engine to cool before refueling. Do
not smoke while refueling.
• Fill fuel tank outdoors with extreme care. Never ll
fuel tank indoors or near appliances with pilot lights,
heaters, or other ignition sources. Replace fuel cap
securely. If fuel is spilled, do not start the engine but
move product and fuel container from area. Clean up
spilled fuel and allow to evaporate.
• Never store the machine or fuel container inside
where there is an open ame (such as a water heater),
or other ignition source.
• If the fuel has to be drained, this should be done
outdoors. The drained fuel should be stored in a
container specically designed for fuel storage or it
should be disposed of carefully.
• Engines give o carbon monoxide, an odorless,
colorless, poison gas. Breathing carbon monoxide
can cause nausea, fainting or death. Always start and
run engine outdoors. Do not start or run engine in an
enclosed area, even if doors or windows are open.
• Never make adjustments or repairs with the engine
(motor) running. Disconnect the spark plug wire,
and keep the wire away from the plug to prevent
accidental starting (remove the ignition key if
equipped with an electric start). Always wear eye
protection when you make adjustments or repairs.
• Check the mower head and engine mounting bolts at
frequent intervals for proper tightness.
• Keep all nuts and bolts tight and keep equipment in
good condition. Check mounting hardware on mower
head every time you change mower line and prior to
each use.
• Never tamper with safety devices. Check their proper
operation regularly.
• When servicing or repairing the mower, do not tip the
machine over or up unless specically instructed to
do so in this manual. Service and repair procedures
can be done with the mower in an upright position.
Some procedures will be easier if the machine is lifted
on a raised platform or working surface.
• To reduce re hazard, keep mower free of grass,
leaves, or other debris build-up. Clean up oil or fuel
spillage. Allow mower to cool before storing.
• Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.
• Always disconnect spark plug wire before cleaning,
repairing, or adjusting.
• Do not change the engine governor setting or over-
speed the engine.
• Clean and replace safety and instruction decals as
necessary.
• To guard against engine over-heating, always have
engine debris lter mounted and clean.
• Inspect mower before storage. When not in use,
disconnect spark plug lead and store indoors in a dry
place locked or otherwise inaccessible to children.
• Use only original equipment or authorized
replacement parts.
• Never replace the cutting lines with metal parts.

Mower Tips:
• If the weeds or grass are tall and thick, operate the
mower at a slower walking speed.
• Frequently clean the underside of the mower to
remove any grass build up. See the "Maintenance,
Service and Storage" section for details.
• For best results and longer lasting line, use the ends
of the line to do the cutting. This is easily done by
moving slowly through very thick or heavy weeds.
• If the mower lines become too short, it will take
longer to complete the job. If the mower lines are
worn to less than half their original length, change to
a new mower line. See more on how to replace the
mower line in the "Maintenance, Service and Storage"
section.
• Do not mow on excessively steep slopes. If a slope
is dicult to stand on, do not mow. Do not mow
on slopes when the ground is slippery or wet. Mow
across the face of a slope, not up and down.
• Mower head contact to concrete, asphalt and harder
surfaces may create premature wear to the height
guide.
PRIMER
BULB
WARNING
• DO NOT LEAVE STRING MOWER
UNATTENDED WHILE ENGINE IS RUNNING.
WAIT FOR THE MOWER LINES TO STOP
ROTATING.
• NEVER RUN THE ENGINE INDOORS OR IN
A POORLY VENTILATED AREA. ENGINE
EXHAUST CONTAINS CARBON MONOXIDE,
AN ODORLESS AND DEADLY GAS.
KEEP HANDS, FEET, HAIR AND LOOSE
CLOTHING AWAY FROM THE MOWER AND
ANY MOVING PARTS ON THE ENGINE.
AVOID TOUCHING THE MUFFLER AND
SURROUNDING AREAS. TEMPERATURES
MAY EXCEED 150 DEGREES FAHRENHEIT.
• DEBRIS SUCH AS STICKS, GRAVEL OR
ROCKS CAN BE THROWN WITH SUFFICIENT
FORCE TO CAUSE PERSONAL INJURY OR

SERVICE AND ADJUSTMENT
How to Change Engine Oil
Be sure the engine is not operating and is located on a level
surface before checking or relling oil. Engine should be warm
for easy removal of oil.
1. Detach spark plug wire and move away from spark plug.
If the engine uses a battery, disconnect at negative
terminal.
2. Remove dipstick and carefully tip the engine toward the
dipstick side to empty oil from oil ll area. Empty oil into
a suitable oil container and dispose of oil properly. SEE
FIGURE 7
3. Tip engine back onto a level surface and ll with
appropriate oil to the top of the marking on the dipstick
(SEE FIGURE 8). DO NOT OVERFILL. For proper oil
capacity and specication, see the engine manufacturer's
instructions.
4. Reinsert dipstick and tighten.
How to Replace the Mower Line
For the best performance, use a heavy gauge (0.155” (4 mm)
diameter) mower line. Cut the length of the mower line to 15"
(381 mm). Use the length guide, located on the shield, to make
sure the mower line is the correct length. Place one end of the
mower line at location "A" and bend it along the raised portion
of the shield. Cut line at location "B". SEE FIGURE 9
NOTE: Do not allow the length of the lines to vary more
than one inch. This is important to make sure the mower
head is balanced and does not vibrate.
To extend the life of the mower line, keep the
mower line moist. If not kept moist, the nylon
mower line will become dry and brittle. Keep extra
mower line in a can of water. The line will then stay
exible and easy to change. A exible line will also
last much longer.
1. Stop the engine. Wait for all moving parts to stop.
2. Remove the worn mower line from the line retainer
by pulling on exposed 1" line from outfeed hole. SEE
FIGURE 10
3. Push one end of the new mower line through the
insertion hole in the head. SEE FIGURE 10
4. Push the line in until approximately 1 " (25 mm) is exposed
on the outfeed side.
5. Repeat for each of the four locations.
Make sure the line length is the
same at all four locations.
WARNING
BEFORE YOU INSPECT, CLEAN OR SERVICE THE

String Mower M220
STORAGE
When the mower is put in storage for thirty days or more,
follow the steps below to make sure the mower is in good
condition the following season.
Mower:
Completely Clean The Mower
Remove and discard line or store in a sealed container. Put the
mower in a building that has good ventilation.
NOTE: A yearly check-up or tune-up at an authorized
service dealer will ensure that the mower will
provide maximum performance for the next
season.
Engine:
IMPORTANT NOTE:
It is important to prevent gum deposits from
forming in fuel system parts such as the
carburetor, fuel lter, fuel hose, and tank during
storage. Also, using alcohol blended fuels (called
gasohol, ethanol or methanol) can attract
moisture which leads to separation and formation
of acids during storage. Acidic gas can damage
the fuel system of an engine while in storage.
1. Drain all gasoline from the fuel tank. Let the engine run
until it is out of gasoline. If you do not want to remove
gasoline, add a fuel stabilizer to any gasoline left in the
tank. A fuel stabilizer will minimize the formation of gum
deposits and acids. If the tank is almost empty, mix the
fuel stabilizer with fresh gasoline in a separate container
and add the mixture to the tank. Always follow the
instructions on the stabilizer container. Run the engine
at least ten minutes after stabilizer is added to allow the
mixture to reach the carburetor.
2. Drain the oil from a warm engine. Fill the engine crankcase
with new oil.
3. Remove the spark plug from the cylinder. Pour one ounce
of oil into the cylinder. Slowly pull the recoil starter
handle so that the oil will protect the cylinder. Install a
new spark plug in the cylinder.
4. Completely clean the mower, including dirt and debris
from the cylinder cooling ns and the engine housing.
5. When not in use, disconnect spark plug lead and store in a
well-ventilated area inaccessible to children.
