• Stop equipment and inspect blades after striking objects or if an abnor mal vibration occurs . Mak e necessar y re pairs before resuming operations .

Page 5

• K ee p hands and feet a w a y from the cutting units .

• Nev er car r y passeng ers and k ee p pets and b ystanders a w a y .

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

• Slo w do wn and use caution when crossing roads and sidew alks . Stop blades if not mo wing .

• Be a w are of the mo w er disc harg e direction and do not point it at any one .

• Do not operate the mo w er under the inﬂuence of alcohol or dr ugs .

• Use extreme care when loading or unloading the mac hine into a trailer or tr uc k.

• Use care when approac hing blind cor ners , shr ubs , trees , or other objects that ma y obscure vision.

• 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)

• K ee p the roll bar in the raised and loc k ed position and use the seat belt when operating the mac hine .

Operation

Note: Deter mine the left and right sides of the

mac hine from the nor mal operating position.

Adding Fuel

Use unleaded regular g asoline suitable for automoti v e use (85 pump octane minim um). Leaded regular g asoline ma y be used if unleaded regular is not a v ailable .

Important: Nev er use methanol, gasoline containing methanol, or gasohol containing mor e than 10% ethanol because the fuel system could be dama ged. Do not mix oil with gasoline.

In cer tain conditions, gasoline is extr emel y ﬂamma ble and highl y explosi v e. A ﬁr e or explosion fr om gasoline 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 gasoline that spills.

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

In cer tain conditions during fueling , static electricity can be r eleased causing a spar k which can ignite the gasoline v apor s. A ﬁr e or explosion fr om gasoline can bur n y ou and other s and can dama ge pr oper ty .

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

• Do not ﬁll gasoline 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 gasoline dispenser nozzle.

• If a gasoline 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.

• Do not ﬁll the fuel tank completel y full. Add gasoline 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 gasoline to expand.

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

• Stor e gasoline 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 gasoline.

• Do not operate without entir e exhaust system in place and in pr oper w or king condition.

Gasoline 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.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the mac hine to pro vide the follo wing beneﬁts:

• K ee ps g asoline fresh during storag e of 90 da ys or less . F or long er storag e it is recommended that the fuel tank be drained.

Page 16

• Cleans the engine while it r uns

• Eliminates gum-lik e v ar nish buildup in the fuel

system, whic h causes hard star ting

Important: Do not use fuel additi v es containing methanol or ethanol.

Add the cor rect amount of g as stabilizer/conditioner to the g as .

Note: A fuel stabilizer/conditioner is most effecti v e when mix ed with fresh g asoline . T o minimize the c hance of v ar nish de posits in the fuel system, use fuel stabilizer at all times .

Filling the Fuel Tank

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

2. Clean around eac h fuel tank cap and remo v e the cap .

3. Add unleaded regular g asoline to both fuel tanks , until the lev el is 1/4 to 1/2 inc h (6 mm to 13 mm) belo w the bottom of the ﬁller nec k.

T his space in the tank allo ws g asoline to expand. Do not ﬁll the fuel tanks completely full.

4. Install fuel tank caps securely .

5. Wipe up any g asoline that ma y ha v e spilled.

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 .

Important: Do not use the motion contr ol lev er s as anchor s f or tieing the machine do wn.

• 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 .

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 29 ). 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 29 ). 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.

• Securely fasten the mac hine to the trailer or

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

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.

Page 28

Operating Tips

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.

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 .

Figure 29

2. Full width ramp 4. Full width ramp—side view

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 .

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.

Page 29

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 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 .

Evaporative Emission Control Warranty Statement

California Evaporative Emission Control Warranty Statement

Your Warranty Rights and Obligations

Introduction

The California Air Resources Board and The Toro® Company are pleased to explain the evaporative emission control system’s warranty on your 2006 model year equipment. In California, new equipment that use small off-road engines must be designed, built, and equipped to meet the State’s stringent anti-smog standards. The Toro® Company must warrant the evaporative emission control system on your equipment for two years provided there has been no abuse, neglect or improper maintenance of your equipment.

Your evaporative emission control system may include parts such as: fuel lines, fuel line ttings, and clamps.

Manufacturer’s Warranty Coverage:

This evaporative emission control system is warranted for two years. If any evaporative emission-related part on your equipment is defective, the part will be repaired or replaced by The Toro® Company.

Owner’s Warranty Responsibilities:

• As the equipment owner, you are responsible for performance of the required maintenance listed in your Operator’s Manual.

The Toro® Company recommends that you retain all receipts covering maintenance on your equipment, but The Toro® Company cannot deny warranty solely for the lack of receipts.

• As the equipment owner, you should however be aware that The Toro® Company may deny you warranty coverage if your emission

warranty parts have failed due to abuse, neglect, or improper maintenance or unapproved modications.

• You are responsible for presenting your equipment to an Authorized Service Dealer as soon as the problem exists. The warranty

repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have a question regarding your warranty coverage, you should contact The Toro® Company at 1-952–948–4027 or call us toll free at the number listed in your Toro Warranty statement.

Defects Warranty Requirements:

1. The warranty period begins on the date the engine or equipment is delivered to an ultimate purchaser.

2. General Evaporative Emissions Warranty Coverage. The emission warranty parts must be warranted to the ultimate purchaser and any subsequent owner that the evaporative emission control system when installed was:

A. Designed, built, and equipped so as to conform with all applicable regulations; and B. Free from defects in materials and workmanship that causes the failure of a warranted part for a period of two years.

3. The warranty on evaporative emissions-related parts will be interpreted as follows: A. Any warranted part that is not scheduled for replacement as required maintenance in the written instructions must be

warranted for the warranty period of two years. If any such part fails during the period of warranty coverage, it must be repaired or replaced by The Toro® Company. Any such part repaired or replaced under the warranty must be warranted for a time not less than the remaining warranty period.

B. Any warranted part that is scheduled only for regular inspection in the written instructions must be warranted for the warranty

period of two years. A statement in such written instructions to the effect of “repair or replace as necessary” will not reduce the period of warranty coverage. Any such part repaired or replaced under warranty must be warranted for a time not less than the remaining warranty period.

C. Any warranted part that is scheduled for replacement as required maintenance in the written instructions must be warranted

for the period of time prior to the rst scheduled replacement point for that part. If the part fails prior to the rst scheduled replacement, the part must be repaired or replaced by The Toro® Company. Any such part repaired or replaced under warranty must be warranted for a time not less than the remainder of the period prior to the rst scheduled replacement point for the part.

D. Repair or replacement of any warranted part under the warranty provisions of this article must be performed at no charge to

the owner at an Authorized Service Dealer.

E. Notwithstanding the provisions of subsection (D) above, warranty services or repairs must be provided at an Authorized

Service Dealer.

F. The owner must not be charged for diagnostic labor that leads to the determination that a warranted part is in fact defective,

provided that such diagnostic work is performed at an Authorized Service Dealer.

G. Throughout the evaporative emission control system’s two year warranty period, The Toro® Company must maintain a supply

of warranted parts sufcient to meet the expected demand for such parts.

H. Manufacturer approved replacement parts must be used in the performance of any warranty maintenance or repairs and must

be provided without charge to the owner. Such use will not reduce the warranty obligations of The Toro® Company.

I. The use of any add-on or modied parts will be grounds for disallowing a warranty claim made in accordance with this

article. The Toro® Company will not be liable under this Article to warrant failures of warranted parts caused by the use of an add-on or modied part.

J. The Toro® Company shall provide any documents that describe the warranty procedures or policies within ve working

days of request by the Air Resources Board.

The following lists includes the parts covered under this warranty:

• Fuel Lines

• Fuel Line Fittings

• Clamps
