Safe Operation Practices for Ride-on (riding) Rotary Lawnmower Machines

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 instr uctions carefully . Be familiar with the

controls 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 brak e . T he main reasons for loss of control are:

◊ insufﬁcient wheel g rip;

◊ being dri v en too fast;

◊ inadequate braking;

◊ the type of mac hine is unsuitable for its

task;

◊ lac k of a w areness of the effect of g round

conditions , especially slopes;

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

refuelling .

– 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 tanks and container caps

securely .

• R e place faulty silencers .

• 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.

• 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 of more than 12-1/2 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 g oing up

or do wnhill;

– use lo w speeds on slopes and during tight tur ns;

Page 5

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

hidden hazards;

• Use care when pulling loads .

– 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 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

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 can 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 can 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 ,

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, this should be

done outdoors .

• W hen mac hine is to be park ed, stored or left

unattended, lo w er the cutting means .

Operating Tips

Fast Throttle Setting

F or best mo wing and maxim um air circulation, operate the engine at the F ast 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 .

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 .

Cutting Speed

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

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.

Cutting a Lawn for the First Time

Cut g rass slightly long er than nor mal to ensure that 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 .

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.

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 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 .

T his product has a limited to wing capacity for small attac hments , suc h as leaf sw ee pers , rollers up to 500 lbs (227 kg) or car ts up to 5 cubic feet. T hese types of attac hments should be limited to ﬂat g round. Nev er allo w c hildren or others in or on to w ed equipment. On slopes , the w eight of to w ed equipment ma y cause a loss of traction and control. T ra v el slo wly and allo w extra distance to stop .
