Be careful with fluids under pressure
Pressure can be maintained in the hydraulic circuit long after the engine has been shut down. ¡Release all pressure before working on
the hydraulic system.
¡Hydraulic fluid under pressure can
penetrate the skin or eyes and cause injury, blindness or death. Fluid escaping from a small hole can be almost invisible. Wear a safety goggles and heavy gloves and use a piece of cardboard or wood to search for suspected leaks. If fluid is injected into the skin, it must be removed within a few hours by a doctor familiar with this type of injury.
Release all pressure before working on the hydraulic system
Oil may spurt out if caps or filters are removed or pipes disconnected before releasing the pressure in the hydraulic system. ¡Gradually loosen the vent plug to relieve
tank pressure.
¡Move all the control levers and pedals
several times in all directions to release the pressure from the working equipment circuitry. (For TB125/TB135: When equipped with accumulator)
¡When removing plugs or screws or
disconnecting hoses, stand to the side and loosen slowly to gradually release the internal pressure before removing.
Be careful with grease under pressure
The track adjuster contains highly pressurized grease. If the tension is adjusted without following the prescribed procedure, the grease discharge valve may fly off, resulting in injury.
¡Do not loosen the grease nipple. ¡Loosen the grease discharge valve slowly. ¡Do not put your face, arms, legs or body
in front of the grease discharge valve.
¡If no grease is expelled when grease
discharge valve is loosened, there is a problem. Contact your nearest service outlet for repairs. DO NOT disassemble, as this is very dangerous.

SAFETY
Maintenance Precautions
Disconnect the battery
Disconnect the battery before working on the electrical system or doing any welding. Remove the negative (–) battery cable first. When reconnecting the battery , connect the negative (–) battery cable last.
Avoid battery hazards
¡Batteries contain sulfuric acid which will
damage eyes or skin on contact.
• If acid contacts eyes, flush immediately with clean water and get prompt medical attention.
• If acid is accidentally swallowed, drink large quantities of water or milk and call a physician immediately.
• If acid contacts skin or clothing, wash off immediately with clean water.
¡Wear safety glasses and gloves when
working with batteries.
¡Batteries generate flammable and
explosive gases. Keep arcs, sparks, flames and lighted tobacco away.
¡Use a flashlight to check battery electrolyte
level.
¡Stop the engine and shut off electrical
equipment while inspecting or handling the battery.
¡Do not short circuit the battery posts with
metal items.
¡Always unfasten the negative (–) battery
cable first when disconnecting the battery cable. Always connect the negative (–) battery cable last when fastening the battery cable.
¡Loose battery terminals may result in
sparks. Be sure to fasten terminals tightly .
¡Make sure the vent caps are tightened
securely.
¡Do not charge a battery or jump-start the
engine if the battery is frozen. Warm to 15°C (60°F) or the battery may explode.
¡Do not use the battery when the fluid level
is below the lower level. Doing so will hasten the deterioration of the internal portions of the battery and shorten the battery life, and can also cause rupturing (or an explosion).
¡Do not fill the battery above the upper
level. Doing so could cause the fluid to leak, contact and damage the skin, or cause parts to corrode.

SAFETY
Maintenance Precautions
Have a T akeuchi service agent repair welding cracks or other damage
Ask a Takeuchi service agent to re pair any welding problems which are detected. If not feasible, make sure the w elding is done by a qualified person in a properly equipped workplace.
Checks after maintenance
¡Gradually raise the engine speed from a
low idle to maximum speed and check that no oil or water is leaking from serviced parts.
¡Move the controls and check that the
machine is operating properly.
Disposing of wastes
¡Funnel spent fluids from the machine into
containers. Disposing of fluids improperly destroys the environment.
¡Follow the prescribed regulations when
disposing of oil, fuel, engine coolant, refrigerant, solvents, filters, batteries or other harmful substances.
Handling of the Accumulator
High pressure nitrogen gas is enclosed in the accumulator and incorrect handling could possibly bring about serious personal injury due to explosion. The following matters should be strictly observed:
¡Do not disassemble. ¡Do not bring close to fire or throw into a
fire.
¡Do not make hole, weld, or fuse. ¡Do not subject to shock such as hitting or
rolling.
¡At time of disposal, it will be necessary to
release the enclosed gas. Please contact a Takeuchi sales or service outlet.

different devices with those specified on the Fuel and Lubricant Chart. Refer to page 94 “Fuel and Lubricant Chart”.
¡When using one-season type antifreeze
coolant, completely drain the antifreeze coolant, carefully clean the inside of the coolant system, then add tap water. Refer to page 120 “Cleaning the Engine Cooling System”.
Preparing for Cold Weather
In cold weather , it may be difficult to start the engine and the coolant may freeze. Make the preparations described below.
Changing the Fuel and Lubricant
Change the fuel, hydraulic oil and engine oil to types suited for cold conditions. Refer to page 94 “Fuel and Lubricant Chart”.
Engine Coolant
W ARNING
The coolant is combustible. Keep flames away.
Use long-life coolant (antifreeze) and tap water for the engine coolant. Supplement: New machines are delivered with JIS T ype 2 long-life coolant (antifreeze) at a concentration of 50%. Refer to page 94 “Fuel and Lubricant Chart”.
Battery
As the temperature drops, the battery performance decreases. Inspect the battery. If the charge is low, contact a Takeuchi sales or service outlet to have the battery charged. Refer to page 113 “Inspecting the Battery Fluid Level and Replenishing”.

OPERATION
Handling Rubber Crawlers
¡Do not let fuel, oil, salt or chemical solvents
get on the crawlers. These substances may corrode the couplings of the crawlers’ metal cores, resulting in rust or peeling. If these substances should get on the crawlers, wipe them off immediately using water .
¡Traveling on roads directly after asphalting
or on hot surfaces such as over fires or on iron sheets under strong sunlight may result in irregular wear or damage of the lugs.
¡Do not move earth in places where the
rubber crawlers may slip. Doing so may speed up lug wear.
Rubber crawlers have an inherent weakness due to their use of rubber. Be sure to heed the prohibitions and cautions below so as to prevent damage to the crawlers and crawler slippage.
Prohibited Actions
Do not travel or operate the machine in the following places:
¡Traveling or slewing on broken stone,
jagged base rock, iron rods, iron scraps or the edges of iron sheets may damage or cut the crawlers.
¡Traveling on riverbeds or places with many
soft rocks may cause the crawlers to slip off or be damaged due to rocks getting stuck in them.
¡Do not use on the seashore. The salt may
corrode the metal cores.

OPERATION
Handling Rubber Crawlers
Cautions
Heed the following cautions when operating the machine:
¡Do not turn the undercarriage with the front
of the machine body lifted using the hoe attachment and the upperstructure left in this posture. Doing so will twist the crawler with the load concentrated on a single point on the crawler belt, rapidly leading to damage.
¡Avoid changing course abruptly and
spinning on concrete surfaces whenever possible. Doing so may wear or damage the rubber crawlers.
¡Avoid drops that may expose the rubber
crawlers to strong shocks.
¡Salt, potassium chloride, ammonium
sulfate, potassium sulfate, and triple superphosphate of lime can damage the crawler belts. If any of these substances should get on the crawler belts, wash them off thoroughly with water.
¡Do not let the sides of the rubber crawlers
rub against concrete or walls.
¡Do not damage the rubber crawlers by
hitting the bucket against them.
¡Be especially careful in the winter on
snowy or frozen surfaces as the crawler belts tend to slip.
¡Use rubber crawler belts at temperatures
between -25°C to +55°C (-14°F to 131°F).
L4D013
¡When storing the rubber crawlers for long
periods of time (3 months or more), do so indoors in a place not exposed to direct sunlight or rain.
¡Rubber crawler belts are not as stable as
steel crawler belts since the entire lug is rubber. Be very careful when slewing and swinging sideways.
Preventing the Rubber Crawlers from Slipping Off
Heed the following in order to prevent the rubber crawlers from slipping off: ¡Always keep the crawlers at the proper
tension.
¡When traveling up large cobblestone or
rock steps (20 cm(8 in.) or greater), climb up the step at a direct angle and do not change course on top of the step.
86
OPERATION
Handling Rubber Crawlers
¡Do not change directions when the crawler
belts are slack as shown in the diagram.
¡When climbing in reverse, do not change
course at the point where the slope starts.
¡Avoid traveling with one crawler on a slope
or projecting object and the other crawler on a flat surface (with the machine at a tilt of 10° or greater). Travel with both crawlers on flat surfaces.
