Operating the Machine with
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.
<TB125 / TB135 / TB145>
On machines equipped with an accumulator,
the residual pressure in the auxiliary
hydraulic circuits can be released within a
specific amount of time after the engine is
stopped.
<TB125 / TB135>
On the TB125/TB135, the residual pressure
in the working equipment circuitry can be
released in addition to the residual pressure
in the auxiliary hydraulic circuit. Operate the
lever to lower the boom during a period of 5
minutes after the engine is stopped.
Releasing the residual pressure
After using the machine, pressure remains
in the hydraulic circuits. This is called the
residual pressure. Use the procedure below
to release the residual pressure as
necessary.
WARNING
Perform the operation to release the residual
pressure within 5 minutes after stopping the
engine.
1. Push back the throttle lever and idle the
engine at low speed.
2. Lower the bucket and dozer blade to the
ground.
3. Check that the safety lock lever is in the
released position.
4. Stop the engine.
5. Turn the starter switch to the ON position.
6. Press both the auxiliary hydraulic switches
(A) and (B) several times to release the
residual pressure in the circuitry.
<TB125 / TB135>
Move all the control levers and pedals
several times in all directions to release
the pressure from the working equipment
circuitry.
7. Set the safety lock lever to the lock
position.
<TB125 / TB135>
Lowering the boom when the engine has
stopped.
Perform this operation within 5 minutes after
stopping the engine.
1. Check that the safety lock lever is in the
released position.
2. Check that the starter switch is in the ON
position.
3. Push the operating lever slowly forward
to lower the boom.
