Warning
●When performing inspection, maintenance, or re-
pair, be sure to turn o󱐯 the engine and make sure
rotation of the blades has stopped.
●Do not perform inspection, maintenance, or repair
while the mower is operating. If an object becomes
trapped in the blades while the engine is running
and causes the blades to stop, removal of that ob-
ject could cause the blades to begin moving again
instantly, resulting in a serious accident.
3. Cautions before Operation
■ In Case of Injury
●Keep a list of phone numbers for medical facilities, re
departments, and ambulance services in an easily vis-
ible location near a telephone.
●A list of landmarks (addresses, buildings, etc.) near
locations where you often work can be helpful for
providing precise information in an emergency when
contacting a re department.
●When working alone, make a habit of noting information
about the workplace on a blackboard, etc. so that the
workplace can be clearly recognized by anyone. Such a
sign can be useful in case an accident occurs and you
are unable to return.
●Keep a rst aid kit and extra cloths and towels at the
workplace. Cloths and towels are useful to stop bleed-
ing in an emergency.
●Local fire departments are trained in emergency
response procedures, and work to promote related tech-
niques and knowledge. Do not miss any opportunity to
receive such training, in order to learn the techniques
and knowledge for responding to emergencies.
■ Be sure to stop the engine before performing inspection, mainte-
nance, or repair.
●Do not perform inspection, maintenance, or repair while
the mower is operating.
●Prepare the necessary tools and equipment to perform
this work after the engine has completely cooled.
■ Allow the engine to cool before performing inspection, mainte-
nance, or repair.

■ Perform a preliminary inspection of the area to be mowed.
■ Stop the engine if there are abnormal vibrations.
●When loading the mower onto a truck for transport,
be sure to engage the brake and perform loading/
unloading together with at least one other person. See
“Transporting the mower by vehicle” on page 22.”)
Warning
●When loading the mower onto a truck for trans-
port, do not drive the mower by running the en-
gine.
Otherwise, mistaken operation could cause a
serious accident.
Warning
●Before performing work, inspect the workplace
and remove any objects that could become
caught in the blades, such as small rocks and
hard debris.
If objects become caught in the blades, they
could be scattered throughout the nearby area
and cause injury to workers and/or supervi-
sors.
●Before performing work, inspect the workplace
for areas with steep inclines. The mower can-
not be used on inclines of 10 degrees or great-
er.
Warning
●If vibrations of unknown origin occur while per-
forming work, immediately turn the engine
switch to “OFF”.
Failure to do so could damage the engine or
blades, or cause personal injury due to the
scattering of hazardous material, hot oil, or
gas.

Cautions before Operation
10
■ Maintain correct posture when operating the mower and/or run-
ning the engine.
■ Wear appropriate clothing.
Warning
●Maintain correct posture when operating the
mower and/or running the engine. Falling and/

Warning
●Do not operate the mower while taking medica-
tion.
Even commonly used medication can affect
judgment and alertness. Be especially careful
when using cold medicine or pain relievers.
●Do not operate the mower when drinking or un-
der the inuence of alcohol.
Alcohol affects judgment and alertness, and
leads to accidents that cause serious injury.
Warning
●Take appropriate breaks when performing mow-
ing work during cold seasons. During long
hours of work, symptoms such as pain in fin-
gertips, hands, and arms due to vibration and
chill could appear.
●If you experience pain while operating the mow-
er, immediately stop working and consult a phy-
sician.
These symptoms could be signs of Raynaud’s
syndrome.
Firstaidkit
●If you experience pain in your ngertips, hands, or arms while operating the mower in low tempera-
tures, immediately stop working and consult a physician. The symptoms of Raynaud’s syndrome,
including chronic pain in ngertips, hands, and arms, are said to appear during long exposure to low
temperatures.
It is unknown whether this syndrome is caused by temperature or time of exposure. Therefore, when
performing mowing work in cold areas or during cold seasons, be sure to take su󱐰cient breaks in
order to restore body temperature to your ngertips and hands.

Preparations before Operation
■ Inspecting/replacing engine oil
Important
●Use API : SE, SAE : 10W―30, or a similar type
of engine oil in this mower.
●Inspect the engine oil every day before starting
work.
〈Inspecting engine oil〉
●The engine oil inspection opening is on the front of the
engine.
1. Place the mower in a level area, and place a strong
board (wood, block, etc.) under the front roller so that
the inspection openings on the front and back are level.
●Use a strong board and make sure the front roller does not
slide o󱐯 of it during the inspection.
2. Turn the oil gauge counterclockwise to remove it.
3.
Use a clean white cloth to wipe the graduations on the
oil gauge, and then inspect the oil on the cloth for con-
taminants.
●If the oil is black or contains contaminants, replace the oil
even if the replacement date has not yet been reached.
4. Insert the oil gauge once again into the inspection
opening (do not screw it in), and then remove it and in-
spect the oil on the graduations to check the volume of
oil.
●Always maintain the oil volume so that oil marks the top
graduation position on the oil gauge. If the oil volume is

Preparations before Operation
〈Replacing engine oil〉
●Drain engine oil from the drain bolt installation opening on the back of the engine.
●Replace the engine oil for the rst time after the rst 20 hours of use from the date the mower was
purchased, and then at approximately every 100 hours
of use thereafter.
1.
Place the mower in a level area, hold the handle, place
the stand on the ground, and lower it carefully back-
wards into a stable position.
●Place a weight on the handle to prevent the mower from fall-
ing forward.
2.
Place an oil drain pan behind the engine.
●The engine can hold 0.6 liters of engine oil. Prepare an oil
drain pan of su󱐰cient size.
3.
Use a box wrench to turn the drain bolt on the back of
the engine counterclockwise to loosen and remove it.
●As the drain bolt loosens, oil will begin to drain out of the
engine. Slowly remove the drain bolt while adjusting the
position of the oil drain pan as necessary.
●The oil will ow out more quickly and smoothly if you loosen
the oil gauge in the engine oil inspection opening on the
front of the engine.
4.
After the oil is completely drained, return the drain bolt
to its original position, and turn it clockwise to tighten
it securely.
5. Holding the handle, return the mower to its original po-
sition. Use a cloth to wipe away any oil on the mower.
6. Place the mower in a level area, and place a strong
board (wood, block, etc.) under the reel unit so that the
inspection openings on the front and back are level.
●Use a strong board and make sure the reel unit does not
slide o󱐯 of it during the inspection.
7. <1}<}60{>Turn the oil gauges on the front and back of
the engine counterclockwise to remove them, and then
add oil until it reaches the top position on the oil gaug-
es.
●Pour oil in through the oil gauge installation opening.

Preparations before Operation
■ Checking the operation of the brakes, main clutch, and blade clutch
〈Checking the operation of the brakes〉
1. When griping the brake lever, if you do not feel any
braking power, or if the brakes do not operate at all, it
is possible that the brake wire has snapped or rusted.
Contact a Shibaura sales office to request inspection
and replacement of the brake wire.
2. Holding the grips on the handle with both hands,
squeeze and hold the brake lever (locked) while trying
to move the mower forward and backward, and conrm
that the mower does not move.
●If the mower does move, the brake wire has stretched and
requires adjustment. See “Adjusting the brakes” on page
32.”)
〈Checking the operation of the main clutch〉
1. With the engine stopped, grip the main clutch lever and
pull it into the “Run” position (toward you).
●When the midpoint of the range in which the main clutch
lever moves has been passed, the lever will naturally fall
toward the operator.
●When the main clutch lever is in the “Run” position, if you
do not feel any resistance, or if the clutch does not operate
at all, it is possible that the clutch wire has snapped or
rusted. Contact a Shibaura business or sales office to
request inspection and replacement of the clutch wire.
2.
Place the shift knob in the “H” or “L” position.
3. Move the main clutch lever completely in to the “Run”
position, hold the handle with both hands, and try
pushing and pulling the mower forward and backward
to conrm that the mower will not move.
●If the mower does move, the main clutch wire has stretched
and requires adjustment. See “Adjusting the main clutch”
on page 33.)

Preparations before Operation
〈Checking the operation of the blade clutch〉
1. W i t h the engine stopped, grip the blade clutch lever and
pull it into the “Run” position (toward you).
●When the midpoint of the range in which the blade
clutch lever moves has been passed, the lever will
naturally fall toward the operator.
●When the blade clutch lever is in the “Run” position,
if you do not feel any resistance, or if the clutch does
not operate at all, it is possible that the clutch wire has
snapped or rusted. Contact a Shibaura business or
sales office to request inspection and replacement of
the clutch wire.
2.
Place the shift knob in the “H” or “L” position.
3. Move the blade clutch lever completely in to the “Run”
position, hold the handle with both hands, and try pull-
