GENERAL

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  hy-

draulic 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  link  type 

controls) 

•  When  removing  plugs  or  screws  or  disconnect-

ing  hoses,  stand  to  the  side  and  loosen  slowly 

to gradually release the internal pressure before 

removing.

Handling of the Accumulator

High pressure nitrogen gas is enclosed in the accu-

mulator and incorrect handling could possibly bring 

about serious 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 agent.

Be careful with grease under pressure

E3A6201

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.

•  Loosen the grease discharge valve slowly. Do not 

unfasten it more than one full turn.

•  Do not put your face, arms, legs or body in front 

of the grease discharge valve.

Disconnect the battery

Disconnect the battery before working on the electri-

cal system or doing any welding. Remove the nega-

tive (–) battery cable first. When reconnecting the 

battery, connect the negative (–) battery cable last.
