the mower deck.

3.2. When you are working with co-workers, be sure to

alert them by signalling before you take a new
action.

3.3. Be sure to mow only in daylight. Mowing in the dark

may cause unexpected accidents.

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. Never allow other persons to get on the Zero turn

mower during operation.

3.7. When turning the Zero turn mower, slow down suffi-

ciently. Turning at high speed may cause the Zero
turn mower to turn over.

3.8. When reversing the Zero turn mower, make sure of

the safety conditions behind.

3.9. 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.

3.10. 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.

3.11. Always pay attention in front of the Zero turn mower

to avoid obstacles such as corner stones, stubs,
sprinkler heads, etc. When there is an obstacle that
cannot be removed, provide a marker flag as a
warning to keep away from it when mowing. When
approaching the obstacle, slow down the Zero turn
mower sufficiently to avoid it.

3.12. Never rest a foot on the brake pedal. If so, the

brakes disc wear rapidly, which may lead to serious
accidents.

3.13. 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.

3.14. After striking a foreign object, stop the engine and
inspect the Zero turn mower and the mower deck
for damage and be sure to make repairs before
mowing again.

3.15. 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.

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

3.17. 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.

3.18. 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.

4. OPERATION ON A SLOPE

We cannot recommend this Zero turn mower be operated
on a slope, but advise you to use a Zero turn mower
designed for slope operation. On a slope, various ele­ments of operation such as slope angles, ground condi­tions, way of operation, grass conditions, etc. may lead to
slipping, or over-turning of the Zero turn mower, which
may result in bodily injury.

If the Zero turn mower has to be used on a slope, remem­ber there is no such thing as a "safe" slope. and be sure
to abide by the following instructions.

•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.

- The Zero turn mower is not equipped with any attach­ments or a cabin.

- The Zero turn mower is equipped with a standard
mower deck.

4.1. Be sure to wear a helmet during operation.

4.2. Operate at sufficiently low speeds.

4.3. When turning, be sure to slow down sufficiently.

4.4. Avoid sudden starting and stopping.

4.5. Operate the Zero turn mower up and down across

the contour lines of the hill. Never operate along the
contour lines.

4.6. Never perform mowing operation on wet grass.

4.7. Never park the Zero turn mower on a slope.

4.8. Pay attention to other possible causes of danger

which could lead to overturning, etc.

5. DRIVING ON PUBLIC ROADS:

5.1. This Zero turn mower cannot be driven on a public

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.

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 attach­ments or a cabin.

• The Zero turn mower is equipped with a standard

7. WHEN FILLING WITH FUEL:

7.1. Never smoke while refilling with fuel, nor allow any

open flames near the Zero turn mower.

7.2. Never open the fuel tank cap while the engine is

running or while it is still hot after operation. Wait
until the engine cools down sufficiently.

7.3. Provide adequate measures to prevent fuel from

spilling when pouring it into the fuel tank. Spilt fuel
should be wiped off completely.

7.4. Avoid refueling indoors. If this is inevitable, provide

sufficient ventilation.

7.5. Replace the fuel tank and container caps securely.

7.6. Store fuel in containers specifically designed for this

purposes.

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.

9.3. When servicing the Zero turn mower or mounting or

dismounting the mower deck, place the Zero turn
mower on level, hard ground.

ZERO TURN MOWER

15

9.4. Service the Zero turn mower in a place sufficiently

illuminated, or darkness may cause unexpected
accidents.

9.5. When servicing the Zero turn mower or mounting or

dismounting the mower deck, stop the engine and
remove the engine key and apply the parking
brakes.

9.6. The engine, muffler, radiator, etc. are very hot just

after operation, so wait until those heated parts cool
down sufficiently to avoid burns.

9.7. 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.

9.8. 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.

9.9. When servicing the Zero turn mower, use proper

tools. Using makeshift tools may lead to injuries or
poor service, which may result in unexpected acci­dents during operation.

9.10. 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.

9.11. When servicing the mower blades, pay sufficient

care so your hands or fingers are not cut by them.
As the three blades are driven by one belt, turning
one blade will cause the other blades to turn.

9.12. A first aid kit and a fire extinguisher should be kept

in a place always in instant access.

9.13. Avoid high-pressure fluids. Escaping fluid under

pressure can penetrate the skin and cause serious
injury, so keep hands and body away from pin holes
and nozzles ejecting such fluids. Be sure to consult
your dealer about the hydraulic and fuel injection
system troubles.

CHAPTER 1. FOR SAFE OPERATION

16

9.14. 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.

9.15. Never allow grass or leaves to accumulate around

heated parts such as the engine and the muffler, or
this may cause a fire.

9.16. Be sure to reinstall the removed parts in place.

Never attempt to start the engine with any parts
removed.

9.17. 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.

9.18. Keep all nuts, blots and screws tight to be sure that

the equipment is in safe working condition.

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.

(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.

12. BEFORE STORING THE ZERO TURN MOWER

12.1. After opeation, be sure to close the fuel cock to pre-

vent 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 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. 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.
