DANGER: Failure to observe the following
safety instructions can result in serious
injury or death. As the owner or operator
of the lawn mower, you are responsible
for preventing accidents or injuries.
1. HOW TO BE A SAFE OPERATOR
1.1. Follow all the safety signs on the lawn mower
and all the manufacturer’s instructions before
starting the lawn mower. If you do not, it may
result in body injuries.
1.2. Pay attention to the caution labels on the lawn
mower, mower deck and collector, and observe
the instructions they give to avoid physical inju-
ries.
1.3. Ensure that all operators are responsible indi-
viduals who have read the instructions or been
fully trained on the safe operation of the lawn
mower.
1.4. All operators should evaluate their health
and ability to operate the lawn mower safely
enough to protect themselves and others from
serious injury. Do not operate the lawn mower
while you are under the influence of alcohol or
drugs.
1.5. Understand how to properly and safely operate
and maintain the lawn mower. Seek and ob-
tain practical instruction on how to operate and
maintain the lawn mower properly.

2. BEFORE STARTING THE LAWN MOWER
2.1. Set up an operation plan with sufficient time al-
lowance. A tight plan may result in unexpected
accidents. Especially when operating the lawn
mower under extremely hot, cold, or humid cir-
cumstances, set up an operation schedule or
method which will ensure operational safety.
2.2. Mow only in daylight or good artificial light.
Mowing in the dark may cause unexpected ac-
cidents.
2.3. Thoroughly inspect the mowing area and re-
move all objects from the mowing area that the
lawn mower can throw, such as stones, toys,
sticks, and wires, which may lead to serious
accidents.
2.4. Ensure that there are no people or pets in the
area where you will mow. Keep children out of
the mowing area and under the watchful care
of a responsible adult.
2.5. Do not operate the lawn mower unless the op-
erator’s presence controls, safety switches, and
guards are attached and functioning properly.
2.6. Start the engine from operator’s seat.
2.7. Before starting the engine, make sure that ev-
erything is safe around the lawn mower and put
the traction drive in neutral, apply the parking
brake or parking lock, and disengage the cut-
ting unit(s). Otherwise, unexpected accidents
may occur.
2.8. Start the engine with the starter switch only.
Never attempt to start the engine by shorting
the terminals, or the lawn mower may move
abruptly, and result in unexpected accidents.
2.9. Do not run the engine in an enclosed area
where dangerous carbon monoxide fumes can
collect. Sufficient ventilation should be provided
when starting the engine in an enclosed area.
2.10. Make sure of safety around the lawn mower
and move slowly when starting. Abrupt starting
may cause unexpected accidents.
2.11. Become familiar with the operation, particularly,
the stopping of the lawn mower. You should
be skilful enough to be able to stop the lawn
mower at will.
2.12. Use only attachments and accessories ap-
proved by the manufacturer and install and op-
erate them as directed.
FIG. 4

FOR SAFE OPERATION

2.13. Be sure to operate the lawn mower equipped
with a standard mower deck and collector. Nev-
er mow grass without the collector, or the lawn
mower scatters grass, stone and other flying
debris, which is very dangerous. If you would
like not to collect the cut glass in a collector,
equip an optional discharge cover for collector.
• Discharge cover for SBC550XL
(8664-705-200-00) -----------------------------1pc
• Discharge cover for SBC600XH
(8664-755-500-00) -----------------------------1pc
2.14. When your lawn mower is equipped with an im-
plement other than a standard mower deck and
collector, never fail to ask your dealer about
machine balance. Always follow their advice.
2.15. Keep in mind that the operator or user is re-
sponsible for the accidents or hazards caused
by the lawn mower to other people or their
property.
2.16. Inspect the lawn mower for wear or damage.
Replace any worn or damaged parts.
2.17. Especially before starting the mower, be sure to
perform advised pre-operation inspections es-
pecially on the brake and inspect visually to see
that the blade and blade tightening nuts are not
worn, damaged or loose. Replace worn or dam-
aged blade and nuts as an assembly to pre-
serve blade balance. Otherwise, poor braking
or scattered broken blades may result, which is
very dangerous.

3. OPERATION OF THE LAWN MOWER
3.1. When the lawn mower is running, stay away
from the discharge opening, the cutting unit(s),
and all moving parts.
3.2. During operation, never allow anyone, especial-
ly children, and animals to be in the vicinity of
the lawn mower. Do not direct the discharge
at anyone.
3.3. When you are working with coworkers, be sure
to alert them by signalling before you take a new
action.
3.4. When operating the lawn mower, you should
be seated in the operator’s seat properly, hold
the steering wheel by both hands, and look in
the direction in which the lawn mower advanc-
es. Avoid looking aside or holding the steering
wheel by one hand during operation.
3.5. Always be sure to operate the lawn mower
from the operator’s seat. Never attempt to get
on or off the lawn mower while it is travelling.
3.6. Do not mow on wet grass. The lawn mower
may slide.
3.7. Slow down before turning the lawn mower.
Turning at high speed may cause the lawn
mower to turn over.
3.8. Never attempt to depress the differential lock
pedal while turning around the lawn mower.
Turning with the differential lock on may cause
the lawn mower to turn over.
3.9. Look down and behind you and ensure a clear
path before you move the lawn mower back-
ward.
3.10. Do not mow while moving backward unless it is
absolutely necessary.
3.11. Never operate the lawn mower in terrain where
there are ditches, holes, or steps easy to col-
lapse. In such a place, the lawn mower could
turn over or fall.
3.12. Before making access to moving parts, stop
the engine, and keep your hands, feet, cloth-
ing, accessories and etc. away so as not to be
caught in the moving parts of the lawn mower.
3.13. Be alert when you approach blind corners and
objects that may obscure your vision. Watch
for holes, ruts, or bumps. Tall grass can hide ob-
stacles.
FIG. 5

3.14. Never rest a foot on the brake pedal. If so,
the brakes wear rapidly, which may lead to se-
rious accidents.
3.15. Never attempt to do the mowing operation
without the discharge cover in place or with the
cover left open.
3.16. Never attempt to operate without the drive shaft
cover in place.
3.17. Do not attempt to adjust the cutting height while
the engine is running.
3.18. Adjust the cutting height with the gauge wheels
in accordance with the condition of the ground
surface at the working site. Mowing on rough
ground with low cutting height may cause the
blades to hit soil or stones, which is very dan-
gerous.
3.19. If you strike an object or if the lawn mower
vibrates abnormally, stop the lawn mower im-
mediately, wait for all moving parts to stop, and
inspect the cutting unit(s). Make all repairs be-
fore you resume operation.
3.20. Be sure to keep the grass discharging part
clean. A clogged discharging part may cause
the discharge cover to open, resulting in scat-
tering of grass and stones, which is very dan-
gerous.
3.21. Never allow grass or leaves to accumulate
around heated parts such as the engine and
the muffler, or this may cause a fire.
3.22. Before moving the lawn mower to another
place, be sure to stop the mower blades and
lift up the mower deck. Otherwise, they may hit
stones and scatter them around, which is very
dangerous.
3.23. When driving over a levee or a step, stop the
mower blades, lift up the mower deck, and move
the lawn mower straight to the levee and make
it climb over slowly. Avoid climbing over a levee
too high, or the lawn mower may fall sideways
or turn over.
3.24. Stop the cutting unit(s) when you are crossing
gravel areas
3.25. Watch for traffic when you are operating the
lawn mower near a roadway or when crossing
a roadway.

SMM54
10
3.26. Never attempt to use the lawn mower to draw
an implement or a trailer. It is not designed to
draw a load.
3.27. Stay alert and stop the lawn mower if people or
animals enter the area.
3.28. Do not carry passengers.
3.29. Never carry children, even when the mower
blades are not rotating. Children may fall off
the lawn mower and become seriously injured
or prevent you from operating the lawn mower
safely. Children who have been given rides in
the past may suddenly appear in the mowing
area for another ride and be run over or backed
over by the lawn mower.
3.30. Before stopping the engine, be sure to lower
the mower deck onto the ground, apply the
parking brake or parking lock, and move the
PTO lever to the OFF position.
3.31. Before leaving the operating position of the
lawn mower for any reason, always do the fol-
lowing:
- Stop the lawn mower on level ground.
- Stop the cutting unit(s), disengage PTO, and
lower the attachment(s).
- Disengage the drive(s).
- Apply the parking brake or parking lock.
- Stop the engine and wait for all moving parts to
stop.

4. OPERATION ON A SLOPE
DANGER: Slopes are a major factor relat-
ed to accidents with lawn mowers, result-
ing in severe injuries.
We cannot recommend the lawn mower with mower
deck be operated on a slope. All slopes require extra
caution; no slope is safe.
You can lose control of the lawn mower on a slope
because of one of the following:
- the wheels lack traction; you are driving the lawn
mower too fast.
- you are not braking properly; the lawn mower type
is not suited for the task.
- you are unaware of the ground conditions (especially
slopes).
- you incorrectly hitch an attachment or distribute a
load.
If the lawn mower has to be used on a slope, never
use it on a slope of more than “12°”. Even if using it
on a slope of less than “12°”, be sure to abide by the
following instructions.
A slope angle of 12° specified with the lawn mow-
ers equipped with the attachments mentioned
respectively.
- The lawn mower is not equipped with any attach-
ments or a cabin than a standard mower deck and
collector.
- The lawn mower is equipped with a standard mower
deck and collector.
Grass catchers and other attachments can change
the stability of the lawn mower. Follow the instructions
for adding weight to improve the stability of the lawn
mower.
When your lawn mower is equipped with an imple-
ment other than a standard mower deck and collector,
never fail to ask your dealer about machine balance.
Always follow their advice.
4.1. Be sure to wear a helmet during operation.
4.2. If you feel uneasy operating your lawn mower
on a slope, do not mow it.
4.3. Evaluate the terrain to determine what acces-
sories and attachments you will need to be
safe.
4.4. Do not mow near drop-offs, ditches, or em-
bankments. You can tip the lawn mower over
if a wheel is over the edge of a drop-off or if an
edge caves in. Uneven terrain can cause the
lawn mower to overturn.

4.5. Never perform mowing operation on wet grass.
4.6. Avoid sudden starting and stopping.
4.7. Mow up and down a slope; do not mow across
it.
4.8. Mow a slope by moving slowly. Do not sud-
denly change your speed or direction.
4.9. Do not turn on a slope unless it is necessary,
and then, turn slowly downhill, if possible.
4.10. If the tires lose traction, disengage the cutting
unit(s) and proceed slowly, straight down the
slope. Do not apply the brake on the lawn mow-
er that is sliding down a slope. Always keep the
lawn mower in gear, especially when travelling
downhill.
4.11. Do not use the grass catcher(s) while you are
mowing a steep slope.
4.12. Do not try to stabilize the lawn mower by put-
ting your foot on the ground.
4.13. Avoid stopping the lawn mower on a slope.
5. DRIVING ON PUBLIC ROADS
5.1. This lawn mower cannot be driven on a public
road without authorization by a local govern-
ment agency. etc. Therefore it may be illegal for
the lawn mower not only to travel on but also to
cross a public road.
5.2. When transporting the lawn mower on a public
road, load it on a truck.

7. MOUNTING AND DISMOUNTING OF THE MOW-
ER DRIVE SHAFT
The mower gear box is driven through a drive shaft
with universal joints from the lawn mower. When
connecting or disconnecting the shaft, follow the next
instructions.
7.1. Lower the mower deck onto the ground, stop
the engine, remove key from the starter switch,
and apply the parking brake or parking lock be-
fore mounting or dismounting the drive shaft.
7.2. Move the PTO lever to the OFF position ( ).
7.3. Make sure that the PTO shaft and mower
blades stop completely.
7.4. The drive shaft should be mounted or dis-
mounted at the lawn mower side. Never leave
the shaft connected only at the lawn mower
side. If the PTO shaft be driven unexpectedly,
the shaft will be swung around and damage the
lawn mower or cause serious accidents.
8. LAWN MOWER MAINTENANCE
8.1. Never start the engine in a closed place. Ex-
haust fumes contain poisonous carbon monox-
ide, so sufficient ventilation should be provided
when starting the engine indoors.
8.2. Be sure to wear safety glasses and gloves
when servicing the lawn mower.
8.3. When servicing the lawn mower or mounting or
dismounting the mower deck, place the lawn
mower on level, hard ground.

8.7. The engine, muffler, radiator, etc. are very hot
just after operation, so wait until those heated
parts cool down sufficiently to avoid burns.
8.8. Never remove the radiator cap while the engine
is hot or running. Wait until the engine cools
down and then relieve the radiator pressure
by releasing the radiator cap. Carelessly pour-
ing cooling water into the heated radiator can
cause serious damage to the radiator and the
engine. Careless removal of the radiator cap
can cause serious injury because of superheat-
ed water vapour.
8.9. Before servicing the lawn mower, be sure to
move the PTO lever to the OFF position (
) and make sure that the mower blades have
stopped completely. Rotating blades may
cause serious accidents.
8.10. While adjusting the lawn mower, keep your fin-
gers away from all pinch points.
8.11. When servicing the lawn mower, use proper
tools. Using makeshift tools may lead to inju-
ries or poor service, which may result in unex-
pected accidents during operation.
8.12. When removing a tire, chock other tires and
support the lawn mower securely. When install-
ing tires, be sure to tighten the wheel nuts to
the specified torque. Loose nuts may cause
serious accidents.
8.13. The mower blades are sharp and can cut you.
Wrap the mower blades or wear leather gloves
when you service them. On the lawn mower with
two or more mower blades, rotating one mower
blades may cause the other mower blades to ro-
tate.
8.14. Never step on the mower deck, or the mower
deck may be damaged or deformed, which may
lead to breakdown or accidents.
8.15. A first aid kit and a fire extinguisher should be
kept in a place always in instant access.
8.16. On the lawn mowers with hydraulic devices, hy-
draulic fluid escaping under pressure can pen-
etrate and seriously damage the skin, requiring
immediate medical assistance. Do not use your
hand to check for a hydraulic leak; use a piece
of cardboard. Be sure to consult your dealer
about the hydraulic and fuel injection system
troubles.
FIG. 10

SMM54
16
8.17. If any hydraulic fluid is injected accidentally into
the skin, it must be removed within a few hours
by a doctor familiar with this type of injury.
8.18. Never allow grass or leaves to accumulate
around heated parts, such as muffler, engine
and brake, and around terminals of battery,
which have possibility of leakage of electricity
by water. Otherwise, it may cause a fire.
8.19. Replace any worn or damaged parts with the
manufacturer’s recommended parts.
8.20. To reduce the fire hazard, keep the engine,
muffler (silencer), battery area, and fuel storage
area free of debris.
8.21. If fuel has to be drained, this should be done
outdoors.
8.22. Check the brake(s) on the lawn mower fre-
quently and adjust and service the brake(s) as
required.
8.23. Replace faulty mufflers (silencers).
8.24. Do not change the engine governor settings
or overspeed the engine. Operating an engine
at an excessive speed can increase the risk of
personal injury.
8.25. The grass catcher components are subject to
wear and damage, exposing you to moving
parts or thrown objects. Frequently check and
replace them with the manufacturer’s recom-
mended parts when necessary.
8.26. Be sure to reinstall the removed parts in place.
Never attempt to start the engine with any parts
removed.
8.27. Never attempt unauthorized modification of the
lawn mower as this could be very hazardous.
Damaged or worn parts should be replaced
with ISEKI genuine spare parts. Unauthorized
parts may cause breakdown of the lawn mow-
er, accidents, and ISEKI warranty to expire.
8.28. Make sure all fixing bolts or nuts are securely
tightened especially those that hold the mower
blades.
