Safety

◊ the type of mac hine is unsuitable for its

task;

T his mac hine meets or ex ceeds European Standards in effect at the time of production. Ho w ev er , improper use or maintenance b y the operator or o wner can result in injur y . T o reduce the potential for injur y , comply with these safety instr uctions and alw a ys pa y attention to the safety aler t symbol, whic h means CA UTION , W ARNING , or D ANGER—personal safety instr uction. F ailure to comply with the instr uction ma y result in personal injur y or death.

Safe Operating Practices

T he follo wing instr uctions are from the CEN standard EN 836:1997.

T his product is capable of amputating hands and feet and thro wing objects . Alw a ys follo w all safety instr uctions to a v oid serious injur y or death.

Training

• R ead the Operator’ s Manual and other training material carefully . Be familiar with the controls , safety signs , and the proper use of the equipment.

• Nev er allo w c hildren or people unfamiliar with these instr uctions to use the la wnmo w er . Local regulations can restrict the ag e of the operator .

• Nev er mo w while people , especially c hildren, or pets are nearb y .

• K ee p in mind that the operator or user is responsible for accidents or hazards occur ring to other people or their proper ty .

• Do not car r y passeng ers .

• All dri v ers should seek and obtain professional

and practical instr uction. Suc h instr uction should emphasize:

– the need for care and concentration when

w orking with ride-on mac hines;

– control of a ride-on mac hine sliding on a

slope will not be reg ained b y the application of the control lev ers . T he main reasons for loss of control are:

◊ insufﬁcient wheel g rip , especially on

w et g rass;

◊ being dri v en too fast;

◊ inadequate braking;

◊ lac k of a w areness of the effect of

g round conditions , especially slopes;

◊ incor rect hitc hing and load distribution.

Preparation

• W hile mo wing, alw a ys w ear substantial footw ear and long trousers . Do not operate the equipment when barefoot or w earing open sandals .

• T horoughly inspect the area where the equipment is to be used and remo v e all objects whic h ma y be thro wn b y the mac hine .

• W ar ning -Fuel is highly ﬂammable .

– Store fuel in containers speciﬁcally designed

for this pur pose .

– R efuel outdoors only and do not smok e

while refueling .

– Add fuel before star ting the engine . Nev er

remo v e the cap of the fuel tank or add fuel while the engine is r unning or when the engine is hot.

– If fuel is spilled, do not attempt to star t the

engine but mo v e the mac hine a w a y from the area of spillag e and a v oid creating any source of ignition until fuel v apors ha v e dissipated.

– R e place all fuel tank and container caps

securely .

• R e place faulty silencers/m ufﬂers .

• Before using, alw a ys visually inspect to see that

the blades , blade bolts and cutter assembly are not w or n or damag ed. R e place w or n or damag ed blades and bolts in sets to preser v e balance .

• On m ulti-bladed mac hines , tak e care as rotating one blade can cause other blades to rotate .

Operation

• Be aler t, slo w do wn and use caution when making tur ns . Look behind and to the side before c hanging directions .

• Do not operate the engine in a conﬁned space where dang erous carbon mono xide fumes can collect.

Page 5

• Mo w only in da ylight or in g ood ar tiﬁcial light.

• Before attempting to star t the engine ,

diseng ag e all blade attac hment clutc hes and shift into neutral.

• Do not use on slopes g reater than 15 deg rees .

• R emember there is no suc h thing as a safe

slope . T ra v el on g rass slopes requires par ticular care . T o guard ag ainst o v er tur ning:

– do not stop or star t suddenly when on a

slope;

– use slo w speeds on slopes and during tight

tur ns;

– sta y aler t for humps and hollo ws and other

hidden hazards;

• Use care when pulling loads or using hea vy equipment.

– Use only appro v ed dra wbar hitc h points .

– Limit loads to those y ou can safely control.

– Do not tur n shar ply . Use care when

rev ersing .

• W atc h out for trafﬁc when crossing or near roadw a ys .

• Stop the blades from rotating before crossing surfaces other than g rass .

• W hen using any attac hments , nev er direct disc harg e of material to w ard b ystanders nor allo w any one near the mac hine while in operation.

• Nev er operate the mac hine with damag ed guards , shields , or without safety protecti v e devices in place .

• Do not c hang e the engine g o v er nor settings or o v erspeed the engine . Operating the engine at ex cessi v e speed ma y increase the hazard of personal injur y .

• Before lea ving the operator’ s position:

– diseng ag e the po w er tak e-off and lo w er the

attac hments;

– c hang e into neutral and set the parking

brak e;

– stop the engine and remo v e the k ey .

• Diseng ag e dri v e to attac hments , stop the engine , and disconnect the spark plug wire(s) or remo v e the ignition k ey:

– before clearing bloc kag es or unclog ging

c hute;

– before c hec king, cleaning or w orking on

the la wnmo w er;

– after striking a foreign object. Inspect

the la wnmo w er for damag e and mak e re pairs before restar ting and operating the equipment;

– if the mac hine star ts to vibrate abnor mally

(c hec k immediately).

• Diseng ag e dri v e to attac hments when transpor ting or not in use .

• Stop the engine and diseng ag e dri v e to attac hment

– before refuelling;

– before remo ving the g rass catc her;

– before making height adjustment unless

adjustment can be made from the operator’ s position.

• R educe the throttle setting during engine r un-out and, if the engine is pro vided with a shut-off v alv e , tur n the fuel off at the conclusion of mo wing .

Maintenance and Storage

• K ee p all n uts , bolts and screws tight to be sure the equipment is in safe w orking condition.

• Nev er store the equipment with fuel in the tank inside a building where fumes ma y reac h an open ﬂame or spark.

• Allo w the engine to cool before storing in any enclosure .

• T o reduce the ﬁre hazard, k ee p the engine , silencer/m ufﬂer , batter y compar tment and fuel storag e area free of g rass , lea v es , or ex cessi v e g rease .

• Chec k the g rass catc her frequently for w ear or deterioration.

• R e place w or n or damag ed par ts for safety .

• If the fuel tank has to be drained, do this

outdoors .

• On m ulti-bladed mo w ers , tak e care as rotating one blade can cause other blades to rotate .

• W hen mac hine is to be park ed, stored or left unattended, lo w er the cutting means unless a positi v e mec hanical loc k is used.

Slope Operation

• Do not mo w slopes g reater than 15 deg rees .

• Do not mo w near drop-offs , ditc hes , stee p

banks or w ater . W heels dropping o v er edg es can cause rollo v ers , whic h ma y result in serious injur y , death or dro wning .

• Do not mo w slopes when g rass is w et. Slipper y conditions reduce traction and could cause sliding and loss of control.

• Do not mak e sudden tur ns or rapid speed c hang es .

• Use a w alk behind mo w er and/or a hand trimmer near drop-offs , ditc hes , stee p banks or w ater .

• R educe speed and use extreme caution on slopes .

• R emo v e or mark obstacles suc h as roc ks , tree limbs , etc . from the mo wing area. T all g rass can hide obstacles .

• W atc h for ditc hes , holes , roc ks , dips , and rises that c hang e the operating angle , as rough ter rain could o v er tur n the mac hine .

• A v oid sudden star ts when mo wing uphill because the mo w er ma y tip bac kw ards .

• Be a w are that loss of traction ma y occur g oing do wnhill. W eight transfer to the front wheels ma y cause dri v e wheels to slip and cause loss of braking and steering .

• Alw a ys a v oid sudden star ting or stopping on a slope . If tires lose traction, diseng ag e the blades and proceed slo wly off the slope .

• F ollo w the man ufacturer’ s recommendations for wheel w eights or counterw eights to impro v e stability .

• Use extreme care with g rass catc hers or other attac hments . T hese can c hang e the stability of the mac hine and cause loss of control.

Using the Rollover Protection System (ROPS)

Operation

Note: Deter mine the left and right sides of the

mac hine from the nor mal operating position.

Adding Fuel

T he engine r uns on clean, fresh diesel fuel with a minim um octane rating of 40. Purc hase fuel in quantities that can be used within 30 da ys to ensure fuel freshness .

Use summer g rade diesel fuel (No . 2-D) at temperatures abo v e 20° F (-7° C) and winter g rade diesel fuel (No . 1-D or No . 1-D/2-D blend) belo w 20° F (-7° C). Use of winter g rade diesel fuel at lo w er temperatures pro vides lo w er ﬂash point and pour point c haracteristics , therefore easing star tability and lessening c hances of c hemical se paration of the fuel due to lo w er temperatures (w ax appearance , whic h ma y plug ﬁlters).

Use of summer g rade diesel fuel abo v e 20° F (-7° C) will contribute to w ard long er life of the pump components .

Important: Do not use k er osene or gasoline instead of diesel fuel. F ailur e to obser v e this caution will dama ge the engine.

In cer tain conditions, fuel is extr emel y ﬂamma ble and highl y explosi v e. A ﬁr e or explosion fr om fuel can bur n y ou and other s and can dama ge pr oper ty .

• Fill the fuel tank outdoor s, in an open ar ea, when the engine is cold. W ipe up an y fuel that spills.

• Nev er ﬁll the fuel tank inside an enclosed trailer .

• Do not ﬁll the fuel tank completel y full. Add fuel to the fuel tank until the lev el is 1/4 to 1/2 inch (6 to 13 mm) belo w the bottom of the ﬁller neck. T his empty space in the tank allo ws fuel to expand.

• Nev er smok e when handling fuel, and stay a w ay fr om an open ﬂame or wher e fuel fumes may be ignited by a spar k.

• Stor e fuel in an appr o v ed container and k eep it out of the r each of childr en. Nev er buy mor e than a 30-day suppl y of fuel.

• Al w ays place fuel container s on the g r ound a w ay fr om y our v ehicle bef or e ﬁlling .

Fuel is har mful or f atal if s w allo w ed. Long-ter m exposur e to v apor s can cause serious injur y and illness.

• A v oid pr olonged br eathing of v apor s.

• K eep f ace a w ay fr om nozzle and gas tank or conditioner opening .

• K eep gas a w ay fr om ey es and skin.

• Do not ﬁll fuel container s inside a v ehicle or on a tr uck or trailer bed because interior car pets or plastic tr uck bed liner s may insulate the container and slo w the loss of an y static charge.

• W hen practical, r emo v e gas-po w er ed equipment fr om the tr uck or trailer and r efuel the equipment with its wheels on the g r ound.

• If this is not possible, then r efuel such equipment on a tr uck or trailer fr om a por ta ble container , rather than fr om a fuel dispenser nozzle.

• If a fuel dispenser nozzle must be used, k eep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Filling the Fuel Tank

1. Shut the engine off and set the parking brak e .

Page 18

2. Clean around eac h fuel tank cap and remo v e the cap . Add fuel to both fuel tanks , until the lev el is 1/4 to 1/2 inc h (6 to 13 mm) belo w the bottom of the ﬁller nec k. T his space in the tank allo ws the fuel to expand. Do not ﬁll the fuel tanks completely full.

3. Install fuel tank caps securely . Wipe up any fuel that ma y ha v e spilled.

4. If possible , ﬁll the fuel tank after eac h use . T his will minimize possible buildup of condensation inside the fuel tank.

Transporting Machines

Use a hea vy-duty trailer or tr uc k to transpor t the mac hine . Ensure that the trailer or tr uc k has all necessar y lighting and marking as required b y la w . Please carefully read all the safety instr uctions . Kno wing this infor mation could help y ou, y our family , pets or b ystanders a v oid injur y .

T o transpor t the mac hine:

• Loc k the brak e and bloc k the wheels .

• Securely fasten the mac hine to the trailer or

tr uc k with straps , c hains , cable , or ropes .

• Secure a trailer to the to wing v ehicle with safety c hains .

Dri ving on the str eet or r oad w ay without tur n signals, lights, r eﬂecti v e mar kings, or a slo w mo ving v ehicle emblem is danger ous and can lead to accidents causing per sonal injur y .

Do not dri v e machine on a public str eet or r oad w ay .

Page 29

Loading Machines

Use extreme caution when loading units on trailers or tr uc ks . One full width ramp that is wide enough to extend bey ond the rear tires is recommended instead of indi vidual ramps for eac h side of the unit ( Figure 26 ). T he lo w er rear section of the tractor frame extends bac k betw een the rear wheels and ser v es as a stop for tipping bac kw ard. Ha ving a full width ramp pro vides a surface for the frame members to contact if the unit star ts to tip bac kw ard. If it is not possible to use one full width ramp , use enough indi vidual ramps to sim ulate a full width contin uous ramp .

T he ramp should be long enough so that the angles do not ex ceed 15 deg rees ( Figure 26 ). A stee per angle ma y cause mo w er components to g et caught as the unit mo v es from ramp to trailer or tr uc k. Stee per angles ma y also cause the unit to tip bac kw ard. If loading on or near a slope , position the trailer or tr uc k so it is on the do wn side of the slope and the ramp extends up the slope . T his will minimize the ramp angle . T he trailer or tr uc k should be as lev el as possible .

Important: Do Not attempt to tur n the unit while on the ramp; y ou may lose contr ol and dri v e of f the side.

Loading a unit onto a trailer or tr uck incr eases the possibility of backw ard tip-o v er and could cause serious injur y or death.

• Use extr eme caution when operating a unit on a ramp .

• Use onl y a sing le, full width ramp; Do Not use indi vidual ramps f or each side of the unit.

• If indi vidual ramps must be used, use enough ramps to cr eate an unbr ok en ramp surf ace wider than the unit.

• Do not ex ceed a 15 deg r ee ang le betw een ramp and g r ound or betw een ramp and trailer or tr uck.

• A v oid sudden acceleration while dri ving unit up a ramp to a v oid tipping backw ard.

• A v oid sudden deceleration while backing unit do wn a ramp to a v oid tipping backw ard.

A v oid sudden acceleration when dri ving up a ramp and sudden deceleration when bac king do wn a ramp . Both maneuv ers can cause the unit to tip bac kw ard.

Mowing Direction

Alter nate mo wing direction to k ee p the g rass standing straight. T his also helps disperse clippings whic h enhances decomposition and fer tilization.

Mow at Correct Intervals

Nor mally , mo w ev er y four da ys . But remember , g rass g ro ws at different rates at different times . So to maintain the same cutting height, whic h is a g ood practice , mo w more often in early spring . As the g rass g ro wth rate slo ws in mid summer , mo w less frequently . If y ou cannot mo w for an extended period, ﬁrst mo w at a high cutting height; then mo w ag ain tw o da ys later at a lo w er height setting .

Operating Tips

Fast Throttle Setting

F or best mo wing and maxim um air circulation, operate the engine at the fast throttle position. Air is required to thoroughly cut g rass clippings , so do not set the height-of-cut so lo w as to totally sur round the mo w er b y uncut g rass . Alw a ys tr y to ha v e one side of the mo w er free from uncut g rass , whic h allo ws air to be dra wn into the mo w er .

Cutting a Lawn for the First Time

Cut g rass slightly long er than nor mal to ensure the cutting height of the mo w er does not scalp any unev en g round. Ho w ev er , the cutting height used in the past is g enerally the best one to use . W hen cutting g rass long er than six inc hes tall, y ou ma y w ant to cut the la wn twice to ensure an acce ptable quality of cut.

Cut 1/3 of the Grass Blade

It is best to cut only about 1/3 of the g rass blade . Cutting more than that is not recommended unless g rass is sparse , or it is late fall when g rass g ro ws more slo wly .

Cutting Speed

T o impro v e cut quality , use a slo w er g round speed in cer tain conditions .

Avoid Cutting Too Low

If the cutting width of the mo w er is wider than the mo w er y ou previously used, raise the cutting height to ensure that unev en turf is not cut too shor t.

Long Grass

If the g rass is ev er allo w ed to g ro w slightly long er than nor mal, or if it contains a high deg ree of moisture , raise the cutting height higher than usual and cut the g rass at this setting . T hen cut the g rass ag ain using the lo w er , nor mal setting .

When Stopping

If the mac hine’ s forw ard motion m ust be stopped while mo wing, a clump of g rass clippings ma y drop onto y our la wn. T o a v oid this , mo v e onto a previously cut area with the blades eng ag ed.

Keep the Underside of the Mower Clean

Clean clippings and dir t from the underside of the mo w er after eac h use . If g rass and dir t build up inside the mo w er , cutting quality will ev entually become unsatisfactor y .

Blade Maintenance

Maintain a shar p blade throughout the cutting season because a shar p blade cuts cleanly without tearing or shredding the g rass blades . T earing and

Page 32

shredding tur ns g rass bro wn at the edg es , whic h slo ws g ro wth and increases the c hance of disease . Chec k the cutter blades daily for shar pness , and for any w ear or damag e . File do wn any nic ks and shar pen the blades as necessar y . If a blade is damag ed or w or n, re place it immediately with a g en uine TOR O re placement blade .

Inspecting the Blades

1. Inspect the cutting edg es ( Figure 75 ). If the edg es are not shar p or ha v e nic ks , remo v e and shar pen the blades . R efer to Shar pening the Blades .

2. Inspect the blades , especially the cur v ed area ( Figure 75 ). If y ou notice any damag e , w ear , or a slot for ming in this area ( Figure 75 ), immediately install a new blade .

Maintain shar p blades throughout the cutting season because shar p blades cut cleanly without tearing or shredding the g rass blades . T earing and shredding tur ns g rass bro wn at the edg es , whic h slo ws g ro wth and increases the c hance of disease .

Chec k the cutter blades daily for shar pness , and for any w ear or damag e . File do wn any nic ks and shar pen the blades as necessar y . If a blade is damag ed or w or n, re place it immediately with a g en uine T oro re placement blade . F or con v enient shar pening and re placement, y ou ma y w ant to k ee p extra blades on hand.

A w or n or dama ged blade can br eak, and a piece of the blade could be thr o wn into the operator’ s or bystander’ s ar ea, r esulting in serious per sonal injur y or death.

• Inspect the blade periodicall y f or w ear or dama ge.

• R eplace a w or n or dama ged blade.
