SAFETY RULES

Safe Operation Practices for Walk-Behind Mowers

IMPORTANT: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROWING OBJECTS.

FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.

I. GENERAL OPERATION

• Read, understand, and follow all instructions on the
machine and in the manual(s) before starting. Be thor­oughly familiar with the controls and the proper use of the
machine before starting.

• Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.

• Only allow responsible individuals, who are familiar with
the instructions, to operate the machine.

• Clear the area of objects such as rocks, toys, wire,
bones, sticks, etc., which could be picked up and
thrown by the blade.

• Be sure the area is clear of other people before mowing.
Stop machine if anyone enters the area.

• Do not operate the mower when barefoot or wearing open
sandals. Always wear substantial foot wear.

• Do not pull mower backwards unless absolutely neces­sary. Always look down and behind before and while
moving backwards.

• Do not operate the mower without proper guards, plates,
grass catcher or other safety protective devices in
place.

• See manufacturer’s instructions for proper operation
and installation of accessories. Only use accessories
approved by the manufacturer.

• Stop the blade(s) when crossing gravel drives, walks, or
roads.

• Stop the engine (motor) whenever you leave the equip­ment, before cleaning the mower or unclogging the
chute.

• Shut the engine (motor) off and wait until the blade
comes to complete stop before removing grass catcher.

• Mow only in daylight or good artificial light.

• Do not operate the machine while under the influence of
alcohol or drugs.

• Never operate machine in wet grass. Always be sure of
your footing: keep a firm hold on the handle and walk;
never run.

• Disengage the self-propelled mechanism or drive clutch
on mowers so equipped before starting the engine
(motor).

• If the equipment should start to vibrate abnormally, stop
the engine (motor) and check immediately for the cause.
Vibration is generally a warning of trouble.

• Always wear safety goggles or safety glasses with side
shields when operating mower.

II. 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.
Exercise extreme caution when changing direction on
slopes.

• Remove obstacles such as rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Tall grass can hide
obstacles.

DO NOT:

• Do not trim near drop-offs, ditches or embankments.
The operator could lose footing or balance.

• Do not trim excessively steep slopes.

• Do not mow on wet grass. Reduced footing could cause
slipping.

III. CHILDREN

Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine and the mowing activity.
children will remain where you last saw them.

• Keep children out of the trimming area and under the
watchful care of another responsible adult.

• Be alert and turn machine off if children enter the area.

• Before and while walking backwards, look behind and

down

for small children.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.

Never

assume that

IV. SERVICE

• Use extra care in handling gasoline and other fuels.
They are flammable 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.

- Never refuel the machine indoors.

- Never store the machine or fuel container inside
where there is an open flame, such as a water
heater.

• Never run a machine inside a closed area.

• 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.

• Keep nuts and bolts, especially blade attachement
bolts, tight and keep equipment in good condition.

• Never tamper with safety devices. Check their proper
operation regularly.

• Keep machine free of grass, leaves, or other debris
build-up. Clean oil or fuel spillage. Allow machine to cool
before storing.

• Stop and inspect the equipment if you strike an object.
Repair, if necessary, before restarting.

• Never attempt to make wheel height adjustments while
the engine (motor) is running.

• Grass catcher components are subject to wear, dam­age, and deterioration, which could expose moving parts
or allow objects to be thrown. Frequently check compo­nents and replace with manufacturer’s recommended
parts, when necessary.

• Mower blades are sharp and can cut. Wrap the blade(s)
or wear gloves, and use extra caution when servicing
them.

• Do not change the engine governor setting or overspeed
the engine.
