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 20° slope , rearw ard up a 12° slope , or sidew a ys on a 14° 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 .
• 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.
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.
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 .
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 .
Filling the Fuel Tank
1. P ark the traction unit on a lev el surface , lo w er
the loader ar ms , and stop the engine .
2. R emo v e the k ey and allo w the engine to cool.
3. Clean around the fuel tank cap and remo v e it.
4. Add unleaded g asoline to the fuel tank, until
the lev el is just belo w the bottom of the filler
nec k.
Important: T his space in the tank allo ws
gasoline to expand. Do not fill the fuel
tank completel y full.
5. Install the fuel tank cap securely .
6. Wipe up any g asoline that ma y ha v e spilled.
Checking the Engine Oil
Level
1. P ark the traction unit on a lev el surface , lo w er
the loader ar ms , and stop the engine .
2. R emo v e the k ey and allo w the engine to cool.

co v er to raise the lev el to the F (full) mark.
Important: Do not o v erfill the crankcase
with oil because the engine may be
dama ged.
10. R e place the filler cap and dipstic k.
11. Close the hood.
Checking the Hydraulic
Fluid Level
Chec k the h y draulic fluid lev el before the engine is
first star ted and after ev er y 25 operating hours .
Hy draulic T ank Capacity: 12 US g allons (45.4 l)
Use 10W -30 or 15W -40 deterg ent, diesel engine oil
(API ser vice CH-4 or higher).
1. R emo v e the attac hment, if one is installed;
refer to R emo ving an Attac hment.
2. P ark the traction unit on a lev el surface ,
lo w er the loader ar ms , and fully retract the tilt
