CHAPTER 1. FOR SAFE OPERATION

3.12. Never operate the front mower in terrain where there are ditches, holes, or steps easy to collapse. In such a place, the front mower could turn over or fall.

3.13. 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 front mower.

3.14. 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.

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

3.16. Travelling set with the cruise lever should be restricted only to operations in specious, flat areas with an unobstructed view and used with the range shift lever always kept in the low speed position.

3.17. Never attempt to do the mowing operation without the discharge cover in place or with the cover left open.

3.18. Never attempt to operate without the drive shaft cover in place.

3.19. Do not attempt to adjust the cutting height while the engine is running.

3.20. 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.

3.21. If you strike an object or if the front 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.

3.22. 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.

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

3.24. Before moving the front 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.

FIG. 10

SF310,370

4. OPERATION ON A SLOPE

DANGER : Slopes are a major factor related to accidents with front mowers, resulting in severe injuries.

We cannot recommend the front mower with mower deck be operated on a slope. All slopes require extra caution; no slope is safe.

You can lose control of the front 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 front 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 front mower has to be used on a slope, Never use it on a slope of more than “10°”. Even if using it on a slope of less than “10°”, be sure to abide by the following instructions.

A slope angle of 10° is specified with the front mowers equipped with the attachments mentioned respectively .

- The front mower is not equipped with any attachments or

a cabin.

- The front mower is equipped with a standard mower

deck. Grass catchers and other attachments can change the stability of the front mower. Follow the instructions for adding weight to improve the stability of the front mower. When your front 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 ROPS is a safety device.

- Keep the ROPS in the vertical and locked position.

Always use the seat belt when you operate the mower.

Make sure the seat belt can be released quickly in an

emergency.

- The ROPS should only be folded if absolutely necessary

for storage. Do not operate the mower with the ROPS in

the folded position. There is no roll over protection with

the ROPS in the folded position.

- Do not use the seat belt with the ROPS in the folded

position.

- Do not remove the ROPS from the mower. (Recommended seat: MSG83/521/GRAMMER)

4.1. Be sure to wear a helmet during operation.

4.2. If you feel uneasy operating your front 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.

FIG. 12

SF310,370

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

You can tip the front mower over if a wheel is over the edge of a drop-off or if an edge caves in. Uneven terrain can cause the front mower to overturn.

4.5. Never perform mowing operation on wet grass.

4.6. Be sure to shift the 4WD lever to the 4WD position.

4.7. Never use the cruise control during mowing operation.

4.8. Choose a low gear to prevent the need to stop or

shift gears on a slope.

4.9. Avoid sudden starting and stopping.

4.10. Mow up and down a slope; do not mow across it.

4.11. Mow a slope by moving slowly. Do not suddenly

change your speed or direction.

4.12. Do not turn on a slope unless it is necessary, and

then, turn slowly downhill, if possible.

4.13. If the tyres lose traction, disengage the cutting

unit(s) and proceed slowly, straight down the slope. Do not apply the brake on a front mower that is sliding down a slope. Engage the clutch slowly and always keep the front mower in gear, especially when travelling downhill.

4.14. Do not use the grass catcher(s) while you are mow-

ing a steep slope.

4.15. Do not try to stabilize the front mower by putting

your foot on the ground.

4.16. Avoid stopping the front mower on a slope.

5. DRIVING ON PUBLIC ROADS

5.1. This front mower cannot be driven on a public road

without authorization by a local government agency, etc. Therefore it may be illegal for the front mower not only to travel on but also to cross a public road.

5.2. When transporting the front mower on a public road,

load it on a truck or trailer.

CHAPTER 1. FOR SAFE OPERATION

6. LOADING ONTO OR UNLOADING FROM A TRUCK

6.1. When loading the front 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 front mower and have it guided by someone to assist the operator. Never allow other persons to approach the front mower, especially in front of or behind it.

6.3. When loading the front mower onto a truck, lift up

the mower deck fully and advance it straight at sufficiently low speeds. Drive it rearward when unloading it from the truck or trailer.

6.4. If the engine stalls unexpectedly on the ramps,

depress the brake pedals immediately and roll the front mower to the ground by releasing the brakes gradually. Then start the engine and try again.

6.5. Use ramps with the same or better specifications

mentioned below. When the front mower is equipped with the attachments other than those included in the specifications mentioned below, ask your dealers for advice.

Specifications of the ramps

6.6. 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.

6.7. Drive the front mower carefully at the moment the

front mower moves from the ramps onto the platform, for it changes angles abruptly.

6.8. When the front 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 front mower may shift position on the truck, which is very dangerous.

7. WHEN FILLING WITH FUEL

DANGER : Fuel is highly flammable and explosive. T ake 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 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 front mower. When connecting or disconnecting the shaft, follow the next instructions.

8.1. Lower the mower deck onto the ground, stop the engine, draw the engine key, and apply the parking brakes before mounting or dismounting the drive shaft.

FIG. 15

CHAPTER 1. FOR SAFE OPERATION

8.2. Turn the PTO switch 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 front mower side. Never leave the shaft connected only at the mower side. If the PTO shaft be driven unexpectedly, the shaft will be swung around and damage the front mower or cause serious accidents.

9. INSPECTION AND 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 front mower.

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

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

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

9.6. When servicing the front 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 brakes

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 front mower, be sure to turn the PTO switch to the OFF position (

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

9.13. When raising up the mower deck for service, raise up it fully and apply the lift lock of hydraulic cylinder to avoid lowering.

9.14. 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.

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

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

9.17. 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.

9.18. 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.

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

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

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

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

9.23. Check the brake(s) on the front mower frequently and adjust and service the brake(s) as required.

9.24. Replace faulty mufflers (silencers).

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 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, 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 fol-

lowing 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.

FIG. 19

FIG. 21

CHAPTER 1. FOR SAFE OPERATION

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 dealers ahead of time. Such operation should be performed by trained mechanics.

12. BEFORE STORING THE FRONT 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 ignition key to prevent unexpected accidents caused by engine starting by untrained persons or children.

12.4. When storing the front 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 front mower in a place provided with sufficient illumination. Inspection and moving of the front mower in a dark place may lead to unexpected accidents.

12.6. When the front 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 front mower just after operation with a tarpaulin or the like, or the heated engine and related parts may cause a fire.

2.1. THROTTLE LEVER

With this lever, the engine speed is controlled.

: LOW: Shift (Pull) the lever towards the “turtle” mark,

the engine decelerates.

: HIGH: Shift (Push) the lever towards the “rabbit”

mark, the engine accelerates.

This front mower is equipped with Auto throttle system, it raises up engine speed by depressing HST forward/ reverse travel pedal.

IMPORTANT: Don’t use Auto throttle for mowing opera-

tion. Set rated engine speed by hand throttle lever.

2.2. AUTO / 4WD CHANGEOVER LEVER (4WD LEVER)

With this lever, 2WD/4WD automatic change-over and permanent 4WD is selectable.

: 4WD PERM: Shift (push) the lever forward to

engage permanent 4WD mode.

4WD AUT: Shift (pull) the lever rearward to engage

AUTO 4WD mode.

In AUTO 4WD mode, 2WD and 4WD is selected automatically during operation on a level ground, so the lever operation is not required.

When operating on a slope, shift the changeover lever to the 4WD position without fail.

IMPORTANT: Be sure to shift the 4WD lever to the

“AUTO” position when operating on level ground, as level ground operation with the 4WD selected leads to a larger turning radius and may cause turf damage.

IMPORTANT: When shifting the 4WD lever, slow down

the travelling speed below 1 km/h and make the machine go straight.

WARNING: When operating the front mower on a slope, be sure the 4WD lever is locked in the 4WD position from the reasons mentioned below:

In the AUTO position the mechanism shifts to 2WD automatically when the peripheral speed of the front wheels exceeds that of the rear wheels, which means loss of rear wheel driving power.

(1) Throttle lever

(2) 4WD lever

FIG. 34

FIG. 35

FIG. 36

SF310,370

For example, when moving uphill if the front wheels slip, the mechanism stays in 4WD. But moving downhill hill if the front wheels slip and lose grip, and begin to slip down the slope, it shifts to 2WD, that is, braking effect of the HST unit is lost, which means loss of front mower control. From another point of view, when you try to turn the front mower on a slope, rear wheel driving power is lost and the front mower may slip down the slope, which is also very dangerous.

2.3. TILT LOCK LEVER

The steering wheel column is tiltable to gain the optimum wheel angles. To adjust the angles, pull up the tilt lock lever while holding the steering wheel with the other hand, and the lock is released. Select the most adequate angle within the four setting position. Then push down the lever securely to lock the steering wheel column.

CAUTION: Only adjust steering tilt when the machine is parked.

This pedal affects the right-hand front wheel brake alone.

3.5. INDEPENDENT BRAKE PEDAL (LH)(E6 type)

This pedal affects the left-hand front wheel brake alone.

WARNING:

• Never operate the independent brake pedal during travelling as this will cause the front mower to skid sideways or turn over. When stopping, be sure to use the master brake pedal.

• Connect the independent brake pedal except necessary situation.

IMPORTANT: • Use of the independent brake may dam-

age the turf, so don’t use it during operation on turfs.

• When making a quick turn within a garage or a barn, do this at sufficiently slow speed.

3.6. DIF-LOCK PEDAL

To minimize the turning radius of the front mower, the differential is installed, which causes the right and left driving wheels to turn at different speed when turning. On the other hand, it causes the wheels to slip on wet grass or soft ground. In such a case, lower engine speed and depress the dif-lock pedal, and then the differential is locked and both wheels turn at the same speed, which results in straighter travelling.

WARNING:

• Never use the dif-lock when travelling at high speeds.

• It is very dangerous to attempt to turn the front mower with the dif-lock pedal depressed. When turning the front mower, be sure to release the dif-lock pedal.

• When the dif-lock is not released despite releasing the dif-lock pedal, stop the front mower immediately and ask your dealer to repair.

2. ENGINE OIL LEVEL

a. Draw out the engine oil level gauge (dipstick),1, which

is located on the right sidewall of the engine by open-

ing the window plate. b. Wipe the end of the dipstick with dry cloth. c. Then insert it into the engine properly. d. Draw it again. Make sure that the oil level is between

the upper and lower limits. e. If the level is lower than the lower limit, replenish

through the engine oil filler,2, to the upper limit with the

same kind of oil as that in the engine.

CAUTION: Stop the engine and wait around 5 minutes at least before checking the oil level. Engine oil is so hot just after operation as to cause burns and it takes some time as well for all the oil to return to the oil pan.

IMPORTANT:

• Never replenish with a different kind of oil. The addition

of different kind of oil will deteriorate the quality of the

original oil.

• The oil level should not exceed the upper limit.

Excessive oil will cause engine trouble.

• Use oil of the quality recommended by ISEKI or 10W-

30 CC grade of SAE classification or higher quality.

a. You can make access to the transmission oil level

gauge (dipstick),1, on the transmission case by open-

ing the step floor. b. Remove the transmission oil filler. c. Wipe the tip with dry cloth. d. Insert the dipstick into the oil filler opening completely. e. Remove it again. Make sure that the level is between

the upper and lower limits. f. When the oil level is lower than the lower limit, replen-

ish with fresh hydrostatic transmission oil up to the

level between the upper and lower limits.

IMPORTANT: The transmission oil is common with oil for

the hydrostatic transmission (HST) and the hydraulic lift cylinder, so pay sufficient attention not to allow dust, water, and other foreign matter to be trapped in the oil.

4. REDUCTION GEAR CASE OIL LEVEL

The level plug,1, is located on the right side wall of the clutch housing. Remove the plug with a spanner or wrench and check if oil overflows through the plug hole. If so, the level is normal.

No oil overflowing shows low oil level. Replenish with fresh gear oil (SAE80) of the same kind as that in the gear case through the oil filler,2, which is located on the righthand side of the front mower and above the hydraulic oil filter.

IMPORTANT: Before re-installing the oil level plug, wrap

the threads of the plug with sealing tape, or oil may leak out.

- Close the fuel filter cock and loosen the strainer cup.

Then open the fuel cock and evacuate trapped air completely along with fuel out of the stainer cup. Re-tighten the strainer cup. The air trapped between the fuel pump and injectors is evacuated automatically when the starter switch is turned to the ON position (

10. FUEL HOSES

Check the fuel hoses for cracks and fuel leak after every 100 hours of operation. A damaged hose should be replaced with a new one.

11. FAN BELT

WARNING:

• Before checking the fan belt, stop the engine and remove the starter key without fail.

• Wait until the engine and accessories cool down completely to prevent burns.

The fan belt,1, is accessible from the right rear of the engine room by opening the engine hood. Check the belt for tension and damage.

Push down the belt with a finger at the intermediate point between the alternator,2, and crankshaft pulley,3, with a force of 10 kgf (22 lb) and see its deflection,A. If it deflects by about 10 mm (0.4 in.), the tension is proper.

When the belt deflection is improper, correct in the following procedure:

a. Loosen the lock bolt,4, and adjust bolt,5, of the alterna-

tor.

12. MASTER BRAKE PEDAL PLAY

The specified play of the master brake pedal,1, is 20 to 30 mm (0.8 to 1.2 in. ) .

DANGER:

• As the front mower is used, the master

brake pedal play becomes larger.

Excessive play will affect the proper brake

performance, which is very dangerous.

• Before operation, be sure to check the

master brake system.

a. Loosen the 4 lock nuts,2, and turn both the brake

rods,3 & 4, so as for the master brake pedal to have the specified play. The longer the effective length of the rods, the larger the pedal play, and vice versa.

b. After pedal play adjustment, be sure to tighten the 4

lock nuts.

WARNING:

• When the brake rod (LH) is manipulated in

effective length, the play of the independent brake pedal (LH) also changes. So the play should also be corrected (E6 type).

13. NEUTRAL POSITION OF HST

WARNING:

• After a long time of use, the neutral position

of the HST unit can shift, which will cause various troubles such as difficulty in stopping the from mower, changing over between forward travel and reverse travel, etc., which is very dangerous.

IMPORTANT:

• When the HST unit is out of order, ask your dealers to repair it. But when there is no alternative but for the user to adjust it, follow the next instructions.

16. BATTERY

DANGER:

• The battery generates very explosive gases, so avoid smoking and keep sparks and open flames away from the battery. Charging the battery should be done in a place well ventilated to disperse explosive gases as quickly as possible.

• Battery electrolyte is very corrosive and will cause burns, so if it splashes on skin or clothes, wash it off immediately. If acid contacts eyes, flush immediately with clean water and get medical attention.

• When using booster cables, take sufficient safety measures.

 INSPECTION OF ELECTROLYTE LEVEL The battery,1, is installed on the middle of the left hand

side of the front mower. Check to see if the electrolyte level is between the upper and lower limits. When the level is near to the lower limit or below, raise the level with distilled water to the upper limit.

WARNING: Never attempt to keep on using or charging the battery with a electrolyte level lower than the limit, or the battery may explode or its service life be shortened due to deterioration inside the casing.

IMPORTANT: The electrolyte level should always be

kept between the upper and lower limits. A too high level will cause the electrolyte to overflow and corrode other parts.

 HANDLING OF THE BATTERY

WARNING:

• Be sure to connect the battery terminals

correctly.

• The wiring from the battery should be kept

clean and connectors tight. Dirty or loose wiring may cause a fire.

• When disconnecting the battery, disconnect

the negative terminal first and vice versa when connecting.

• When replacing the battery, use a battery of

the same capacity as that of the current on (80D 26R).

a. As atmospheric temperature lowers, the performance

of the battery also lowers. Consequently the battery should be serviced with special care in wintertime.

(1) Battery

(1) Battery A: Upper limit (2) Filler plug B: Lower limit

FIG. 93

FIG. 94

SF310,370

b. As the battery discharges even when it is not used, it

should be charged every or every other month at the maximum.

c. When the front mower is not used for a long time,

remove the battery from the front mower and store it in a place dry and shaded from direct sunshine.

IMPORTANT: Avoid quick charge of battery. Or it will

shorten the service life of the battery.

IMPORTANT: When storing front mower for long period

without operation, self discharge of battery will happen (especially in winter). If the front mower is stored for more than 1 month, the battery minus terminal should be disconnected. When operating for the first time or after long term storage, check if the battery charge level is enough. (If measurement of battery voltage is available, check if the voltage is more than

12.5V.) When the front mower is stored more than 6 months, charge the battery.

IMPORTANT: Don’t throw away the battery to the gar-

bage can. Recycle it with observing the law of your community.

17. TIRE PRESSURE (INFLATION)

Improper tire pressure causes the tires to wear abnor-

mally and affects the front mower performance. Too high pressure causes the front mower to bounce too much and too low pressure increases travelling resistance, which leads to power loss.

Tire pressure should be checked everyday.

WARNING:

• Tire inflation should be set to the values specified in this manual. Excessive inflation may cause certain types to explode, which may result in serious accidents.

• Never use a tire with a cut or crack which

reaches tire cords as such a tire may explode.

• When a tire, tube, or rim is required for

replacement, ask your dealer. Such operation should be done by a mechanic trained especially for tire handling.

• Insufficient pressure in the tires causes

uneven tire friction that can shorten tire lifetime.

 DAILY AND SHORT TERM STORAGE

a. Clean the front mower.

IMPORTANT: When washing the front mower, avoid

applying compressed water directly to the electric apparatus, oil and fuel fillers. Remove the starter key and cap the switch key hole to prevent short circuits.

b. Lower the mower deck on the ground.

CAUTION: A lifted up mower deck may go down unexpectedly if the lift lever is manipulated by children or unauthorised people, which may lead to serious accidents.

c. The front mower should be stored indoors if possible.

When it has to be left outdoors, cover it with tarpaulin or the like.

WARNING: When covering the front mower with tarpaulin, wait until heated components such as the engine, muffler, etc. have cooled down completely. Otherwise a fire may be caused.

d. When the ambient temperature is very low, remove the

battery and store it in a warm shaded dry place. This will contribute greatly to easy starting of the engine the following morning.

CAUTION: Remove the starter key without fail before storage.

 LONG TERM STORAGE a. Clean the front mower and correct all troubles such as

repair, replacement of defective parts, readjustment,

etc. b. Top up the fuel tank and close the fuel cock. c. Replace the engine oil with new and let the engine idle

for about 5 minutes to lubricate every part sufficiently. d. Lubricate all lubrication points. e. Grease up all greasing points. f. Check bolts and nuts for looseness and re-tighten loose

ones. g. Inflate each tire a little higher than specified.

h. Dismount the mower deck or lower it to the ground.

CAUTION: A lifted up mower deck may go down unexpectedly if the lift lever is manipulated children or unauthorised people, which may lead to serious accidents.

i. Cover the front mower with tarpaulin or the like in order

to protect it from rainfall and dust.

WARNING: When covering the front mower with tarpaulin, wait until heated components such as the engine, muffler, etc. have cooled down completely. Otherwise a fire may be caused.

j. Remove the battery, charge it, and store it in a shaded

dry place with no access to children.

k. Charge the battery completely every month.

CAUTION:Remove the starter key without fail before storage.

 OPERATION AFTER A LONG TIME OF STORAGE a. Perform the pre-operation inspection without fail. b. Let the engine idle for about 30 minutes before apply-

ing any load, to ensure maximum engine performance and service life.

WARNING: Provide sufficient ventilation for exhaust fumes when starting the engine, because such fumes are very poisonous.
