Roll-bar type

The remote control levers are used to operate the hydraulic cylinder(s) and/or motor(s) of the
implement attached to the tractor.
 If you
push
the remote control lever(s)
forward
, the hydraulic pressure works
to the lower
couplers
of the related lever(s), and
the upper coupler(s
) is connected
to the drain line
.
 Each lever of the parallel circuit remote control valve can be operated respectively, and when
operating the levers at the same time, a quick coupler under less pressure begins to work first.

After connecting and preliminary operating the hydraulic equipment, check again the transmission
oil level of the tractor.
 Depending on the remote control valve type, spring-return type lever(s), detent type lever(s) or
combinations may be installed on your tractor. (optional)
- Spring-return type
: When releasing the lever after operating fully, the lever will return to the
neutral position automatically.
- Detent type:
When releasing the lever after operating fully, the lever is fixed on the working
position. In this case, you must move the lever to the neutral position manually after operating.
If
leaving this lever on, it may cause an over-heat and serious damage of the hydraulic system.
- Detent with auto-release type:
When releasing the lever after operating fully to the float position
(optional), the lever is fixed on that position. If the system pressure of the actuator line is over the
designated level, the remote control lever will return to the neutral position automatically.

Warning
▶
Before removing hydraulic pipes or hoses and other parts, make sure to check that
hydraulic pressure is relieved completely. The leaks of pressurized oil can cause a
fatal physical injury.
▶
Use proper protection equipments, before servicing hydraulic system.
▶
Before connecting or disconnecting the hydraulic quick coupler, lower the
implements to the ground, and check that hydraulic pressure is relieved.
Caution
▶
When connecting a high volumetric capacity cylinder to the remote control system,
lower the implement to the ground, and check if the transmission oil level is marked
between “Min” and “Max” scale on the oil gauge. If necessary, add new oil.
