all instructions on the machine and in the
manuals before operation. Keep this manual
in a safe place for reference and ordering
replacement parts
• Be completely familiar with the controls
and the proper use of this machine before
operating it.
• This machine is a precision piece of power
equipment, not a plaything. Therefore,
exercise extreme caution at all times. This
machine has been designed to perform
one job: to mow grass. Do not use it for any
other purpose.
• Never allow children to operate this
machine.
• Only responsible individuals who are
familiar with these rules of safe operation
should be allowed to use this machine.
• Thoroughly inspect the area where the
equipment is to be used. Remove all
stones, sticks, wire, bones, toys and other
foreign objects, which could be tripped
over or picked up and thrown by the
blade. Thrown objects can cause serious
personal injury.
• Plan your mowing pattern to avoid
discharge of material toward roads,
sidewalks, bystanders and the like. Also,
avoid discharging material against a
wall or obstruction, which may cause
discharged material to ricochet back
toward the operator.
• To help avoid blade contact or a thrown
object injury, stay in operator zone behind
handles and keep children, bystanders,
helpers and pets at least 75 feet from
mower while it is in operation. Stop
machine if anyone enters area.
• Always wear safety glasses or safety
goggles during operation and while
performing an adjustment or repair to
protect your eyes. Thrown objects which
ricochet can cause serious injury to the
eyes.
• Wear sturdy, rough-soled work shoes,
lose-fitting slacks, shirts and hearing
protection. Shirts and pants that cover
the arms and legs and steel-toed shoes
are recommended. Never operate this
machine in bare feet, sandals, slippery or
light-weight (e.g. canvas) shoes.
• Do not put hands or feet near rotating
parts or under the cutting deck. Contact
with blade can amputate fingers, hands,
toes and feet. Keep clear of the discharge
opening at all times.
• A missing or damaged discharge cover
can cause blade contact or thrown object
injuries.
• Many injuries occur as a result of the
mower being pulled over the foot during
a fall caused by slipping or tripping. Do
not hold on to the mower if you are falling:
release the handle immediately.
• Never pull the mower back toward you
EN - 4
SENIXTOOLS.COM
while you are walking. If you must back the
mower away from a wall or obstruction
first look down and behind to avoid tripping
and then follow these steps:
a. Step back from mower to fully
extend your arms forward.
b. Be sure you are well balanced with
sure footing.
c. Pull the mower back slowly, no more
than half way toward you.
d. Repeat these steps as needed.
• Do not operate the mower while under the
influence of alcohol or drugs.
• Do not engage the self-propelled
mechanism on machines so equipped
while starting engine.
• The blade control handle is a safety
device. Never attempt to bypass its
operation. Doing so makes the safety
device inoperative and may result in
personal injury through contact with the
rotating blade. The blade control handle
must operate easily in both directions and
automatically return to the disengaged
position when released.
• Never operate the mower in wet grass.
Always be sure of your footing. A slip
and fall can cause serious personal
injury. If you feel you are losing your
footing, release the blade control handle
immediately and the blade will stop
rotating within three seconds.
• Mow only in daylight or good artificial light.
Walk, never run.
• Stop the blade when crossing gravel
drives, walks or roads.
• If the equipment should start to vibrate
abnormally, stop the engine and check

generally a warning of trouble.
• Shut the engine off and wait until the blade
comes to a complete stop before removing
the grass catcher or unclogging the chute.
The cutting blade continues to rotate for
a few seconds after the blade control is
released.
• Never place any part of the body in the
blade area until you are sure the blade has
stopped rotating.
• Never operate mower without proper trail
shield, discharge cover, grass catcher,
blade control handle or other safety
protective devices in place and working.
Never operate mower with damaged
safety devices. Failure to do so can result
in personal injury. Check frequently for
signs of wear or deterioration and replace
as needed.
• Muffler and engine become hot and can
cause a burn. Do not touch.
• Never attempt to make a wheel or cutting
height adjustment while the engine is
running.
• Only use parts and accessories made
for this machine by the manufacturer as
listed in the parts pages of this Operator’s
Manual. Failure to do so can result in
personal injury.
• When starting engine, pull cord slowly
until resistance is felt, then pull rapidly.
Rapid retraction of starter cord (kickback)
will pull hand and arm toward engine
faster than you can let go. Broken bones,
fractures, bruises or sprains could result.
• If situations occur which are not covered
in this manual, use care and good
judgement.
SLOPE OPERATION
Slopes are a major factor related to slip and
fall accidents, which can result in severe injury.
Operation on slopes requires extra caution. If
you feel uneasy on a slope, do not mow it. For
your safety, use the Slope Guide included as
part of this manual to measure slopes before
operating this machine on a sloped or hilly
area. If the slope is greater than 15 degrees, do
not mow it.
Do:
• Mow across the face of slopes; never up
and down. Exercise extreme caution when
changing direction on slopes.
• Watch for holes, ruts, rocks, hidden
objects, or bumps which can cause you to
slip or trip. Tall grass can hide obstacles.
Uneven terrain could overturn the
machine, or cause operator to lose their
balance or footing.
• Always be sure of your footing. A slip
and fall can cause serious personal
injury. If you feel you are losing your
balance, release the blade control handle
immediately and the blade will stop
rotating within three (3) seconds.
• Use extra care while operating
machine with a grass catcher or other
attachment(s). They can affect the
stability of the machine.
Do Not:
• Do not start and stop on slopes. Avoid
making sudden changes in speed or
direction. Make turns slowly and gradually.
5 - EN
SENIXTOOLS.COM
• Do not mow near drop-offs, ditches or
embankments, because you could lose
your footing or balance.
• Do not mow slopes greater than 15
degrees as shown on the slope guide.
• Do not mow on wet grass. Unstable footing
could cause slipping.
HAULING
Use full width ramps for loading and unloading
a machine for transport.
BEWARE OF 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. They do not understand the
dangers. Never assume that children will
remain where you last saw them.
• Keep children out of the mowing area and
under watchful care of a responsible adult
other than the operator.
• Be alert and turn mower off if a child
enters the area.
• Before and while moving backwards, look
behind and down for small children.
• Use extreme care when approaching blind
corners, doorways, shrubs, trees, or other
objects that may obscure your vision of a

• Never fill containers inside a vehicle or on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before filling.
• Remove gas-powered equipment from
the truck or trailer and refuel it on the
ground. If this is not possible, then refuel
such equipment on a trailer with a portable
container, rather than from a gasoline
dispenser nozzle.
• Keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until fueling is complete. Do not use
a nozzle lock-open device.
• Extinguish all cigarettes, cigars, pipes and
other sources of ignition.
• Never fuel machine indoors because
flammable vapors will accumulate in the
area.
• Never remove gas cap or add fuel while
engine is hot or running. Allow engine to
cool at least two minutes before refueling.
• Never over-fill fuel tank. To allow for
expansion of the fuel, do not fill above the
bottom of the fuel tank neck.
