3. OPERATION OF THE ZERO TURN MOWER
3.1. When the Zero turn 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
Zero turn mower. Do not direct the discharge at
anyone.
3.3. When you are working with co-workers, be sure to
alert them by signalling before you take a new
action.
3.4. When operating the Zero turn mower with the
ROPS turned up, you should be seated in the operator's seat properly with seatbelt, hold the Control
lever by both hands, and look in the direction in
which the Zero turn mower advances.
3.5. Always be sure to operate the Zero turn mower
from the driver's seat with seat belt. Never attempt
to get on or off the Zero turn mower wihile it is travelling.
3.6. Do not mow on wet grass. the front mower may
slide.
3.7. Slow down before turning the front mower. Turning
at high speed may cause the front mower to turn
over.
3.8. Look down and behind you and ensure a clear path
before you move the front mower backward.
3.9. Do not mow while moving backward unless it is
absolutely necessary.
3.10. Never operate the Zero turn mower in terrain where
there are ditches, holes, or steps easy to collapse.
In such a place, the Zero turn mower could turn
over or fall.
3.11. 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 or the Zero turn mower.
3.12. 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.
3.13. Never rest a foot on the brake pedal. If so, the
brakes disc wear rapidly, which may lead to serious
accidents.
3.14. Never attempt to do the mowing operation without
the discharge cover in place or with the cover left
open.
3.15. Do not attempt to adjust the cutting height while the
engine is running.
3.16. 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.
3.17. If you strike an object or if the Zero turn mower
vibrates abnormally, stop the front mower immediately, wait for all moving parts to stop, and inspect
the cutting unit(s). Make all repairs before you
resume operation.
3.18. 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.
3.19. Never allow grass or leaves to accumulate around
heated parts such as the engine and the muffler, or
this may cause a fire.
3.20. Before moving the Zero turn 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.
3.21. When driving over a levee or step, stop the mower
blades, lift up the mower deck, and move the Zero
turn mower straight to the levee and make it climb
over slowly. Avoid climbing over a levee too high, or
the Zero turn mower may fall sideways or turn over.
3.22. Stop the cutting unit(s) when you are crossing gravel areas.
3.23. Watch for traffic when you are operating the Zero
turn mower near a roadway or when crossing a
roadway.
3.24. Never attempt to use the Zero turn mower to draw
an implement or a trailer. It is not designed to draw
a load.
3.25. Stay alert and stop the lawn mower if people or pets
enter the area.
3.26. Do not carry passengers.
3.27. Never carry children , even when the cutting means
are not moving. Children may fall off the Zero turn

4. OPERATION ON A SLOPE
DANGER: Slopes are a major factor related to
accidents with the Zero turn mowers, resulting in severe injuries.
We cannot recomended the Zero turn mower with mower
deck be oparated on a slope. All slopes require extra caution; no slope is safe.
You can lose control of the Zero turn mower on a slope
because of one of the following:
- the wheels lack traction; you are driving the front
mower too fast.
- you are not braking properly; the Zero turn 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 Zero turn mower has to be used on a slope, Never
use it on a slope of more than "12°". Even if using it on a
siope of less than "12°", be sure to abide by the foiiowing
instructions.
A slope angle of 12°is specified with the Zero turn mower
equipped with the attachments mentioned respectively.
- The Zero turn mower is not equipped with any attach-
ments or a cabin.
- The Zero turn mower is equipped with a standard
mower deck.
Grass catchers and other attachments can change the
stability of the Zero turn mower. Follow the instructions
for adding weight to improve the stability of the Zero turn
mower.
When your Zero turn mower is equipped with an implement other than standard, such as a collector, a cabin,
etc., never fail to ask your dealers about machine balance. Always follow their advice.
We recommended that you use a ROPS if you will operate the Zero turn mower on steep slopes.
A ROPS consists of both a rollover protection device and
a seat belt. Always wear the seat belt with your ROPS; do
not use the seat belt unless the rollover protection device
is also properly installed.
4.1. Be sure to wear a helmet during operation.
4.2. If you feel uneasy operating your Zero turn 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 embank-
ments. You can tip the Zero turn mower over if a
wheel is over the edge of a drop-off or if an edge
caves in. Uneven terrain can cause the Zero turn
mower to overturn.
CHAPTER 1. FOR SAFE OPERATION
FIG. 5
14
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 tyres lose traction, disengage the cutting
unit(s) and proceed slowly, straight down the slope.
Do not apply the brake on the Zero turn mower that
is sliding down a slope. Engage the clutch slowly
and always keep the Zero turn mower in gear,
especially when travelling downhill.
4.11. Do not use the grass catcher(s) while you are mow-
ing a steep slope.
4.12. Do not try to stabilize the Zero turn mower by put-
ting your foot on the ground.
4.13. Avoid stopping the Zero turn mower on a slope.
5. DRIVING ON PUBLIC ROADS:
5.1. This Zero turn mower cannot be driven on a public
road without authorization by a local government
agency. etc. Therefore it may be illegal for the Zero
turn mower not only to travel on but also to cross a
public road.
5.2. When transporting the Zero turn mower on a public
road, load it on a truck or trailer.
ZERO TURN MOWER
15
6. LOADING ONTO OR UNLOADING FROM A TRUCK:
6.1. When loading the Zero turn mower onto a truck,
turn off the truck's engine, apply the parking brakes
to the truck, and chock the wheels to avoid unexpected moving of the truck or trailer.
6.2. Pay sufficient attention to safety conditions around
the Zero turn mower and have it guided by someone to assist the operator. Never allow other persons to approach the Zero turn mower, especially in
front of or behind it.
6.3Use a wide ramp for loading and unloading the
mower. Avoid switching from forward motion to
backward motion (or vice-versa) as this will cause
the front wheels to rotate sideways. Sideway rotation of the front wheels poses some danger when
the mower is on the ramp.
6.4. When loading the Zero turn mower onto a truck, lift
up the mower deck fully and rearward it straight at
sufficiently low speeds. Drive it advance when
unloading it from the truck or trailer.
6.5. If the engine stalls unexpectedly on the ramps,
depress the brake pedals immediately and roll the
Zero turn mower to the ground by releasing the
brakes gradually. Then start the engine and try
again.
FIG. 6
FIG. 7
CHAPTER 1. FOR SAFE OPERATION
16
6.6. Use ramps with the same or better specifications
mentioned below. When the Zero turn mower is
equipped with the attachments other than those
included in the specifications mentioned below, ask
your dealers for advice.
Specifications of the ramps for the SZ330
• Length......more than 4 times the height of the platform
of the truck
•Width (effective width)........................more than 30 cm
• Required quantity ............................................2 ramps
• Capacity (one ramp)..........................more than 750 kg
• Ramps should have anti-skid surfaces.
• The above specifications are effective with the Zero
turn mower with the following configurations.
• The Zero turn mower is not equipped with any attach-
ments or a cabin.
• The Zero turn mower is equipped with a standard
mower deck.
6.7. Park the truck on hard level ground. Hook the
ramps securely on the platform of the truck with the
top of the ramp level with the platform.
6.8. Drive the Zero turn mower carefully at the moment
the Zero turn mower moves from the ramps onto
the platform, for it changes angles abruptly.
6.9. When the Zero turn mower is loaded on the truck,
lower the mower deck onto the truck bed, stop the
engine, apply parking brakes, and withdraw the
starter key, chock the wheels, and rope it securely
to the truck. Refrain from unnecessary abrupt starting, stopping, and turning during transportation, or
the Zero turn mower may shift position on the truck,
which is very dangerous.
7. WHEN FILLING WITH FUEL
DANGER : Fuel is highly flammable and a
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.
FIG. 8
ZERO TURN MOWER
17
7.6. Use only an approved fuel container to store fuel.
7.7. Do not store the front 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 front
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 front
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 Zero turn mower. When connecting or disconnecting the shaft, follow the next instructions.
8.1. Lower the mower deck onto the gournd, stop the
engine, draw the engine key, and apply the parking
brakes before mounting or dismounting the drive
shaft.
8.2. Shift the PTO switch to the OFF position (N).
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 Zero turn mower side. Never leave the shaft
connected only at the Zero turn mower side. If the
PTO shaft be driven unexpectedly, the shaft will be
swung around and damage the Zero turn mower or
cause serious accidents.
9. ZERO TURN 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 Zero turn mower.

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 vapor.
9.9. Before servicing the Zero turn mower, be sure to
turn off the PTO switch to the OFF position and
make sure that the mower blades have stopped
completely. Rotating blades may casue serious
accidents.
9.10. While adjusting the Zero turn mower, keep your fin-
gers away from all pinch points.

tools. Using makeshift tools may lead to injuries or
poor service, which may result in unexpected accidents during operation.
9.12. When removing a tyre, chock other tyres and sup-
port the Zero turn mower securely. When installing
tyres, be sure to tighten the wheel nuts to the specified torque. Loose nuts may cause serious accidents.
9.13. The cutting means(s) are sharp and can cut you.
Wrap the cutting means(s) or wear leather gloves
when you service them.On the front mower with two
or more cutting means rotating one cutting means
may cause the other cutting means(s) 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 front 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 manu-
facturer'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 out-
doors.
9.22. Check the brake(s) on the front 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
Zero turn 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 Zero turn mower, accidents, and ISEKI warranty to expire.
9.28. Keep all fasteners tight, especially those that hold
the cutting means(s).

10.MAINTENANCE OF THE ELECTRIC 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 dis-
connect 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, muf-
fler 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 battely 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.
CHAPTER 1. FOR SAFE OPERATION
22
(3) When replacing or inspection the battely 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, disconnect
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 capacity.
A cable of inadequate capacity will cause generation
of heat, which may lead to a fire.
11. TYRES AND WHEELS
11.1. Be sure to keep tyre pressures at the levels speci-
fied in this manual. Excessively high tyre pressure
may result in explosion, which may lead to physical
accidents.
11.2. If a cut is found in a tyre and the cut reaches the
cords, do not use it. Such a tyre may explode.
11.3. Before replacing or repairing tyres, tubes, or rims,
consult your dealers ahead of time. Such operation
should be performed by trained mechanics.

heated parts such as the engine and the muffler, or
this may cause a fire.
12.3. Be sure to remove the ignition key to prevent unex-
pected accidents caused by engine starting by
untrained persons or children.
12.4. When storing the Zero turn mower with the mower
deck attached, be sure to lower the mower deck on
the ground. Otherwise manipulation of the lift lever
by untrained peroson or children may cause unexpected accidents.
12.5. Store the Zero turn mower in a place provided with
sufficient illumination. Inspection and moving of the
Zero turn mower in a dark place may lead to unexpected accidents.
12.6. When the Zero turn 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, bat-
tery, and fuel storage area free of grass, leaves, or
excessive grease.
12.8. Never cover a hot Zero turn mower just after opera-
tion 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 front
mower, unless you lock the cutting unit(s) into position.
13.3. Allow the engine to cool before storing the front
mower in any enclosure.
13.4. Before storing the Zero turn mower for a long period
of time, disconnect the battery cables to prevent
them, in case they are gnawn 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 or connecting the battery will cause
sparks, which is very dangerous.
