Stability Data
T he follo wing tables list the maxim um slope recommended for the traction unit in the positions listed in
the tables . Slopes o v er the listed deg ree ma y cause the traction unit to become unstable . T he data in the
tables assume that the loader ar ms are fully lo w ered; raised ar ms ma y affect the stability .
In eac h attac hment man ual is a set of three stability ratings , one for eac h hill position. T o deter mine the
maxim um slope y ou can tra v erse with the attac hment installed, find the deg ree of slope that cor responds
to the stability ratings of the attac hment. Example: If the attac hment installed on a TX 420 traction
unit has a F ront Uphill rating of B , a R ear Uphill rating of D , and a Side Uphill rating of C , then y ou
could dri v e forw ard up a 205 slope , rearw ard up a 125 slope , or sidew a ys on a 145 slope , as listed in
the follo wing table for the TX 420 traction unit.

Operation
Note: Deter mine the left and right sides of the
mac hine from the nor mal operating position.
Important: Bef or e operating , check the
fuel and oil lev el, and r emo v e de bris fr om the
traction unit. Also, ensur e that the ar ea is clear
of people and de bris. Y ou should also kno w
and ha v e mar k ed the locations of all utility
lines.
Adding Fuel
Use unleaded g asoline (87 pump octane minim um).
Leaded, regular g asoline ma y be used if unleaded
is not a v ailable .
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.
Important: Do not 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.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the traction
unit 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.
• 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 .
18
Page 19
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 .

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 modications.
• 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

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
