Handle Chemical Products Safely
Direct exposure to hazardous chemicals can cause
serious injury. Potentially hazardous chemicals used with
your machine include such items as lubricants, coolants,
paints, and adhesives.
–UN–26NOV90
A Material Safety Data Sheet (MSDS) provides specific
details on chemical products: physical and health hazards,
safety procedures, and emergency response techniques.
Check the MSDS before you start any job using a TS1132
hazardous chemical. That way you will know exactly what
the risks are and how to do the job safely. Then follow
procedures and recommended equipment.
See your authorized dealer for MSDS’s on chemical
products used with your machine.

Driving the Machine
Using Range Hold
Under certain conditions, the transmission changes up
and down between two gears at short intervals. This is
because power is insufficient for operating in the higher
gear but is sufficient for upshifting from the lower gear.
–UN–27JUL99
The range hold switch (1) has two positions:
• Switch in normal (up) position—range hold OFF
T122891B
• Switch in down position—range hold ON
When switch is ON, the transmission will hold the gear
that it is in at the time the range hold switch is turned ON. 1—Range Hold Switch
2—Gear Selector Display Window
Normal downshifting and upshifting will occur, but
transmission will NOT upshift to a gear higher than the
held gear until the range hold switch is turned OFF. The
exception to this is overspeed condition. (See Engine
Overspeed Indicator in Operator’s Station chapter.)
When range hold switch is turned ON, the gear shift
display window (2), will indicate the gear number that the
transmission will be “held” in.
When range hold switch is turned OFF, normal automatic
operation mode will continue and the display will show the
original value.
When level ground is reached, machine must be operated
with range hold OFF.

Operating the Machine
Uphill Operation
The machine operates in full automatic mode and the
transmission will select the correct gear for traveling uphill.
Engage inter-axle lock to alow for even traction when
operating on slippery roads
Keep engine speed constant at all times when driving
uphill.
Shift cycling or “gear hunting” on certain uphill applications
can be eliminated by correct use of range hold switch.
(See Using Range Hold in Driving the Machine chapter.)
CED,TX03679,5198 –19–29JUL99–1/1
Downhill Operation
Use the exhaust brake and retarder to assist service
brakes and to reduce brake pad wear when driving
downhill.
Slow down before going downhill so the transmission
automatically selects a low gear.
Engage inter-axle lock to improve traction and braking
effect during icy or other slippery conditions.

conditions:
Correct Oil Level
• “O” then “L” are displayed (“OL” represents “Oil Level
Check Mode”). Following are “O” then “K”. The OK
display indicates the oil is within safe operating level.
The sensor display and the transmission dipstick may
not agree because the sensor compensates for oil
temperature.
Low Oil Level
• “O” then “L” are displayed (“OL” represents “Oil Level
Check Mode”). Following are “L” then O” (the LO
represents Low Oil Level) and the number of quarts that
the transmission oil is low, e.g., “0” then “2” indicates
two additional quarts of oil will bring the oil level to safe
operating level.
