I. FOR SAFE OPERATION

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 injuries.

1.3. Ensure that all operators are responsible individu­als 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 obtain
practical instruction on how to operate and main­tain the lawn mower properly.

1.6. Be sure to use necessary protective devices such
as headgear, safety glasses, safety shoes, ear
plugs, gloves, etc.

1.7. Wear appropriate protective clothing and equip­ment when you are operating, adjusting, or ser­vicing the lawn mower, such as safety glasses,
long pants, substantial footwear, and ear protec­tion. Long hair, loose clothing, or jewellery can
get tangled in moving parts.

1.8. Never permit the following persons to operate the
lawn mower:

- Persons not properly trained to operate the lawn
mower

2. BEFORE STARTING THE LAWN MOWER

2.1. Set up an operation plan with sufficient time al­lowance. A tight plan may result in unexpected
accidents. Especially when operating the lawn
mower under extremely hot, cold, or humid cir­cumstances, 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 accidents.

2.3. Thoroughly inspect the mowing area and remove
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 op­erator’s presence controls, safety switches, and
guards are attached and functioning properly.

2.6. Start the engine from the operating or designated
starting position.

2.7. Before starting the engine, make sure that every­thing is safe around the lawn mower and put the
traction drive in neutral, apply the parking brake
or parking lock, and disengage the cutting 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 approved
by the manufacturer and install and operate them
as directed.

FIG. 4

SXG

2.13. Be sure to operate the lawn mower equipped with
a standard mower deck and collector. Never 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
implement 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 respon­sible 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 espe­cially on the brake and inspect visually to see that
the blade and blade tightening nuts are not worn,
damaged or loose. Replace worn or damaged
blade and nuts as an assembly to preserve blade
balance. Otherwise, poor braking or scattered bro­ken blades may result, which is very dangerous.

I. FOR SAFE OPERATION

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, espe­cially 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 advances. 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 dif-lock pedal while
turning around the lawn mower. Turning with the
dif-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 backward.

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 col­lapse. 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, clothing, 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 obstacles.

3.14. Never rest a foot on the brake pedal. If so,
the brakes wear rapidly, which may lead to seri­ous accidents.

FIG. 5

SXG

10

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 dangerous.

3.19. If you strike an object or if the lawn mower vi­brates abnormally, stop the lawn mower immedi­ately, wait for all moving parts to stop, and inspect
the cutting unit(s). Make all repairs before 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 scattering of
grass and stones, which is very dangerous.

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.

3.26. Never attempt to use the lawn mower to draw
an implement or a trailer. It is not designed to
draw a load.

I. FOR SAFE OPERATION

11

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 following:

- 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 related
to accidents with lawn mowers, resulting 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°s specified with the lawn mowers
equipped with the attachments mentioned respectively.

- The lawn mower is not equipped with any attachments

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 implement
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 accesso­ries and attachments you will need to be safe.

4.4. Do not mow near drop-offs, ditches, or embank­ments. 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.

FIG. 7

I. FOR SAFE OPERATION

13

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 suddenly
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 mower
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 putting
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 government
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.

SXG

14

6. LOADING ONTO OR UNLOADING FROM A TRUCK

6.1. When loading the lawn mower onto a truck, turn
off the truck’s engine, apply the parking brake to
the truck, and chock the wheels to avoid unex­pected moving of the truck.

6.2. Pay sufficient attention to safety conditions
around the lawn mower and have it guided by
someone to assist the operator. Never allow other
persons to approach the lawn mower, especially
in front of or behind it.

6.3. When loading the lawn mower onto a truck, lift up
the mower deck fully and reverse it straight back
at sufficiently low speeds. Drive it forward when
unloading it from the truck.

6.4. If the engine stalls unexpectedly on the ramps,
depress the brake pedals immediately and roll the
lawn mower to the ground by releasing the brake
gradually. Then start the engine and try again.

6.5. Use ramps with the same or better specifica­tions mentioned below. When the lawn mower is
equipped with the attachments other than those
included in the specifications mentioned below,
ask your dealer for advice.

7. WHEN FILLING WITH FUEL

DANGER: Fuel is highly flammable and ex­plosive. Take the following precautions.

7.1. Do not add or drain fuel indoors, while smoking,
or near a source of flame.

7.2. Do not remove the fuel tank cap or add fuel to the
tank while the engine is running or hot. Wait until
the engine cools down sufficiently.

7.3. Do not completely fill the fuel tank. Add fuel to the
tank until the level inside the tank is just below
the bottom of the filler neck. The empty space al­lows the fuel to expand.

7.4. If you spill fuel, clean it up and do not attempt to
start the engine until the vapour has dissipated.

7.5. When fuelling under certain circumstances, a
static charge may develop and ignite the fuel.

7.6. Use only an approved fuel container to store fuel.

7.7. Do not store the lawn mower or the fuel container
near a source of open flame, such as a water
heater.

7.8. Replace all fuel tank and container caps securely.

7.9. To prevent personal injury and property damage,
do the following:

- Always place fuel containers on the ground and
away from the vehicle before fuelling.

- Do not fill the fuel container(s) inside a vehicle or
on a truck or trailer bed.

- When practical, remove a fuel-powered the lawn
mower from the truck or trailer and refuel it with
its wheels on the ground.

- If it is not practical to do this, refuel the lawn
mower on a truck or trailer from a portable con­tainer, not fuel dispenser nozzle.

- If you must use a fuel dispenser nozzle, keep the
nozzle in contact with the rim of the fuel tank or
fuel container opening until you have completed
fuelling.

8. MOUNTING AND DISMOUNTING OF THE MOWER

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.

8.1. Lower the mower deck onto the ground, stop the
engine, remove key from the starter switch, and
apply the parking brake or parking lock before
mounting or dismounting the drive shaft.

8.2. Move the PTO lever to the OFF position ( ).

8.3. Make sure that the PTO shaft and mower blades
stop completely.

8.4. The drive shaft should be mounted or dismounted
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.

9. LAWN MOWER MAINTENANCE

9.1. Never start the engine in a closed place. Exhaust
fumes contain poisonous carbon monoxide, so
sufficient ventilation should be provided when
starting the engine indoors.

9.2. Be sure to wear safety glasses and gloves when
servicing the lawn mower.

9.3. When servicing the lawn mower or mounting or
dismounting the mower deck, place the lawn
mower on level, hard ground.

9.4. Service the lawn mower in a place sufficiently il­luminated, or darkness may cause unexpected
accidents.

9.5. Do not adjust or repair the lawn mower while the
engine is running.

9.6. When servicing the lawn mower or mounting or
dismounting the mower deck, stop the engine and
remove the key (if applicable) to prevent some­one from accidentally starting the engine and ap­ply the parking brake or parking lock.

I. FOR SAFE OPERATION

FIG. 11

9.7. The engine, muffler, radiator, etc. are very hot just
after operation, so wait until those heated parts
cool down sufficiently to avoid burns.

9.8. 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 pouring 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 superheated water vapour.

9.9. 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.

9.10. While adjusting the lawn mower, keep your fin­gers away from all pinch points.

9.11. When servicing the lawn mower, use proper tools.
Using makeshift tools may lead to injuries or poor
service, which may result in unexpected acci­dents during operation.

9.12. When removing a tire, chock other tires and sup­port the lawn mower securely. When installing
tires, be sure to tighten the wheel nuts to the
specified torque. Loose nuts may cause serious
accidents.

9.13. 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 rotate.

9.14. Never step on the mower deck, or the mower
deck may be damaged or deformed, which may
lead to breakdown or accidents.

9.15. A first aid kit and a fire extinguisher should be
kept in a place always in instant access.

9.16. On the lawn mowers with hydraulic devices, hy­draulic fluid escaping under pressure can pen­etrate 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.

9.17. 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.

9.18. Never allow grass or leaves to accumulate
around heated parts such as the engine and the
muffler, or this may cause a fire.

9.19. Replace any worn or damaged parts with the
manufacturer’s recommended parts.

9.20. To reduce the fire hazard, keep the engine, muf­fler (silencer), battery area, and fuel storage area
free of debris.

9.21. If fuel has to be drained, this should be done out­doors.

9.22. Check the brake(s) on the lawn mower frequently
and adjust and service the brake(s) as required.

9.23. Replace faulty mufflers (silencers).

9.24. 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.

9.25. 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 recommended parts
when necessary.

9.26. Be sure to reinstall the removed parts in place.
Never attempt to start the engine with any parts
removed.

9.27. 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 mower, acci­dents, and ISEKI warranty to expire.

9.28. Keep all fasteners tight, especially those that hold
the mower blades.

9.29. Check that all safety devices are in place and op­erating properly.

10. MAINTENANCE OF THE ELECTRICAL SYSTEM

10.1. TO MAINTAIN ELECTRIC WIRING

(1) When servicing the electric wiring, stop the engine

without fail. Otherwise your hands or clothes may
be caught in or sandwiched between rotating parts.

(2) Before manipulating electric parts, be sure to

disconnect the earth battery cable (-), or you may
get an electric shock or be injured by sparks.

(3) Loose electric terminals or connectors may not

only lower electrical performance but also cause
short circuit or leakage of electricity, which may
lead to a fire. Promptly repair or replace damaged
wiring.

(4) Remove chaff or dust from the battery, wiring,

muffler or engine. Otherwise it could result a fire.

10.2. TO HANDLE THE BATTERY

(1) When working around the battery, avoid smoking.

The battery generates explosive hydrogen and
oxygen gases when it is being charged. Keep the
battery away from sparks or open flames.

(2) The battery should be inspected before starting

the engine. Be careful not to touch the electrolyte
makes contact with the skin or clothing, wash
it off immediately with water and then consult a
doctor.

(3) When replacing or inspection the battery stop the

engine and turn the main switch off, or electrical
parts may be damaged or unexpected accident
may occur.

(4) When disconnecting the battery cables, discon-

nect the earth cable (-) first without fail. When
connecting the battery cables, connect the posi­tive cable (+) first. Disconnecting or connecting in
wrong order may lead to a short circuit or sparks.

10.3. TO HANDLE BOOSTER CABLES

When using booster cables, pay attention to the

following items for safe operation:

(1) Before connecting cables, remove the vent plugs.

This will lower the force in case of explosion.

(2) Before connecting cables, be sure to stop the

engines. Otherwise unexpected accidents may
occur.

(3) Use booster cables with sufficient electrical ca-

pacity. A cable of inadequate capacity will cause
generation of heat, which may lead to a fire.

11. TIRES AND WHEELS

11.1. Be sure to keep tire pressures at the levels speci­fied in this manual. Excessively high tire pressure
may result in explosion, which may lead to physi­cal accidents.

11.2. If a cut is found in a tire and the cut reaches the
cords, do not use it. Such a tire may explode.

11.3. Before replacing or repairing tires, tubes, or rims,
consult your dealer ahead of time. Such operation
should be performed by trained mechanics.

12. BEFORE STORING THE LAWN MOWER

12.1. After operation, be sure to close the fuel cock
to prevent fuel from spilling, as spilled fuel may
catch fire.

12.2. Never allow grass or leaves to accumulate
around heated parts such as the engine and the
muffler, or this may cause a fire.

12.3. Be sure to remove the key from the starter switch
to prevent unexpected accidents caused by en­gine starting by untrained persons or children.

12.4. When storing the lawn mower with the mower
deck attached, be sure to lower the mower deck
on the ground. Otherwise manipulation of the lift
lever by untrained person or children may cause
unexpected accidents.

12.5. Store the lawn mower in a place provided with
sufficient illumination. Inspection and moving of
the lawn mower in a dark place may lead to unex­pected accidents.

12.6. When the lawn mower is to be stored in a closed
place like a garage or a barn, provide sufficient
ventilation for exhaust gases. Exhaust fumes can
be lethal.

12.7. To avoid fire hazard, keep the engine, muffler,
battery, and fuel storage area free of grass,
leaves, or excessive grease.

12.8. Never cover a hot lawn mower just after operation
with a tarpaulin or the like, or the heated engine
and related parts may cause a fire.

13. LONG TERM STORAGE

13.1. Never store the mower with fuel in the tank inside
a building where fumes can reach an open flame
or spark

13.2. Lower the cutting unit(s) when you store the lawn
mower, unless you lock the cutting unit(s) into
position.

13.3. Allow the engine to cool before storing the lawn
mower in any enclosure.

13.4. Before storing the lawn mower for long period
of time, disconnect the battery cables to prevent
them, in case they are gnaw by rats, from caus­ing a short circuit, which may lead to a fire. When
disconnecting the battery, disconnect the nega­tive (-) cable first, while connecting the positive
(+) cable first when connecting the battery. Wrong
order of disconnecting on connecting the battery
will cause sparks, which is very dangerous.
