RULES FOR SAFE OPERATION
LOOK FOR THIS SYMBOL TO POINT OUT IMPORTANT
SAFETY PRECAUTIONS. IT MEANS ATTENTION!
BECOME ALERT! YOUR SAFETY IS INVOLVED.
EQUIPMENT SAFETY AND TRAINING
● READ the OPERATOR’S Manual Carefully. Be
thoroughly familiar with the controls and the proper use of
the Mower.
● NEVER allow children to operate or ride on the Mower.
Do not allow adults to operate the Mower without proper
instruction.
● KEEP the area of operation clear of all by bystanders,
particularly small children and pets.
● DO NOT operate the Mower if under the influence of
alcohol, medication, or when tired or ill.
PREPARATION TO MOW
● THOROUGHLY inspect the area where the Mower is to
be used and remove all stones, sticks, wires, bones, and other
foreign objects.
● DO NOT operate the Mower when barefoot or wearing
open sandals. Always wear appropriate footwear.
● CHECK the fuel before starting the engine. Do not fill the
Gasoline Tank indoors or when the Engine is running. Wait
until the Engine has cooled for several minutes after running.
Clean up any spilled gasoline before starting the engine.
● KEEP the Blade Drive Lever in the disengaged position and
shift the Transmission into neutral before starting the engine.
Never make a height adjustment or any Mower adjustment
while the engine is running.
● NEVER operate the Mower in wet grass. Always be sure
of your footing; keep a firm hold on the handles and walk;
never run.
OPERATING THE MOWER
● ALWAYS wear safety goggles or safety glasses with side
shields when operating the Mower.
● DO NOT change the Engine Governor setting or
overspend the engine.
● DO NOT put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
● TEST the operation of Blade Drive Lever before each use.
If Blades rotate longer than three seconds after the controls
are disengaged, stop the Engine and immediately contact
your local Worldlawn authorized dealer or call the factory
for instructions. DO NOT use the Mower until the
mechanism is repaired.
● MAKING TURNS: The Mower turns easily by squeezing
the right or left lever.
● WATCH for traffic and STOP the Mower Blade when
crossing gravel drives, walks, or roadways.
● MOW only in daylight or in good artificial light. Always
run the Engine at the fast speed setting for best mowing
performance.
● STOP the Engine after striking a foreign object.
Disconnect the spark plug wire, thoroughly inspect the
Mower for any damage, and repair the damage before
restarting and operating the Mower.
If the Mower should start to vibrate abnormally, STOP the
Engine, disconnect the spark plug wire, and check
immediately for the cause. Vibration is generally a warning
of trouble.
● STOP the Engine whenever you leave the Mower or
during cleaning, repairing, or inspecting. Make certain the
blades and all moving parts have stopped. Disconnect the
spark plug wire and keep the wire away from the plug to
prevent accidental starting.
● MOW across the face of slopes; never up and down.
Exercise extreme caution when changing direction on slopes.
Do not mow on slopes (with an incline of more than 15°).
Exceeding the maximum safe operating angle may cause
tipping and loss of Mower control.
● ALWAYS mow with all Covers in place and the Discharge
Chute in the down position, except if an optional Grass
Catcher is completely installed.
● DO NOT touch Engine parts which may be hot from
operation. Allow parts to cool completely before inspecting,
cleaning, adjusting, refueling, or repairing the Mower.
● Shut off the Fuel Valve at the bottom of the Tank
before transporting the Mower on a trailer, FIG 10.
Failure to do so may cause flooding of the Carburetor due to
road vibration.
USE THE FOLLOWING MAINTENANCE
PROCEDURES TO KEEP YOUR MOWER IN
GOOD OPERATING CONDITION
MAINTENANCE AND STORAGE
● CHECK the Blade and Engine Mounting Bolts at frequent
intervals for proper tightness.
● KEEP all Nuts, Bolts, and Screws tight to be sure the
equipment is in safe working condition.
● NEVER store the Mower with gasoline in the Tank inside
a building where fumes may reach an open flame or spark.
Allow the Engine to cool before storing in any enclosure.
Store gasoline in a cool, well vented area, and only in an
approved container.
● Keep MOWER Blades sharp. Use Caution, wear gloves
and eye protection when servicing and sharpening Blades.
To reduce fire hazard, keep the engine free of grass, leaves,
debris, and grease.

● Check the tires for proper pressure.
Front caster tires 20psi.
Rear tires 20psi.
● Drain and refill the Transmission Oil yearly—use one pint
of SAE 30. FIG 9 & FIG 15.
● Grease all pivots daily, or more often as needed,
depending on operating conditions.
● Use only Worldlawn
®
original equipment replacement
parts. “WILL FIT” parts could present a safety hazard
and void the warranty.

Tipping mower for service
When servicing the underside of the Mower,
make sure Mower is securely blocked up to prevent it from
falling and injuring anyone.
BLADE CARE
For best results, keep Mower Blades sharp. The Blades can
be sharpened with a few strokes of a file or dressed on a
grinding wheel. DO NOT attempt to sharpen Blades while
on the Mower.
1. When sharpening the Blades, take care to maintain Blade
balance. Check for proper balance before reinstalling.
Replace bent or damaged Blades.
2. To ensure good cutting performance, install new Blades at
the start of each mowing season.
DAILY MAINTENANCE
1. Make sure all Nuts and Bolts are tight and Pins securely in
place. Especially make certain the Engine and Blade
Bolts/Nuts are tightened properly.
2. Remove grease, spilled oil, accumulated dirt, and
clippings from around belts and underside of Mower.
3. Grease Fittings are provided on important parts requiring
lubrication. See FIGS 3 & 10.
SAFETY DECALS
Make certain that all Safety Decals on the Mower are kept
clean and in good condition. For Replacement, please refer
to the Parts Catalog that accompanied the Mower.
