develop if proper medical treatment is not
administered immediately.
• Do not move the loader control lever into the
float position when the bucket is off the ground.
To begin test operation, follow the following procedure.
1. Slightly move the control lever from the
“N” position.
2. Slowly raise the boom of the loader just enough for
the bucket to clear the ground when fully dumped.
3. Slowly work through the dump and roll back cycles.
NOTE :
• When the control lever is at each corner
position marked by asterisk [*], cylinder of the
boom and bucket work at the same time.
However, the lower left position (raise and roll
back) is not recommended for scooping
because of insufficient lift force.
IMPORTANT :
• If the boom or bucket of the loader does not
work in the directions indicated on the label,
follow the following procedure.
1. Lower the bucket to the ground.
2. Stop the engine.
3. Relieve all hydraulic pressure.
4. Recheck
and correct all hydraulic
connections and oil level.
1. Four position bucket control valve
type
This control valve has two stage dump positions. The
first dump position by moving the lever to the right
features greater speed for dumping.
The second dump position (to further right) is the
regular dump position. It has good power and control
for dumping precisely. This position should be used
when operating another implement with this control
valve.
These two positions are separated by a detent for your
convenience.
PURGING AIR FROM THE
HYDRAULIC SYSTEM
1. Repeat operations of raising and lowering the boom
and dumping and rolling back the bucket until all the
air is removed from the hydraulic system and the
hydraulic system responds properly.
IMPORTANT :
• Do not move the loader control lever into the
float position when the bucket is off the
ground.
DUAL REMOTE HYDRAULIC
CONTROL SYSTEM
The tractor is equipped with the double-acting 2-
segment hydraulic control valve for front loader.
To apply the hydraulic power take-off for general
attachments, keep the following point in mind.
• Control lever and hydraulic hose connections.
• Loader/remote control valve lever.
1. Connecting the control lever and
the hydraulic hose
IMPORTANT :
To avoid damage to the attachments:
• Do not connect the attachments through the
hydraulic motor to the [C] and [D] ports.
If the control lever is moved to the regeneration
position (R
1
), the seals on the hydraulic motor
will be damaged.
• The control valve is provided with the
regeneration position (R
1
).
When the [C] and [D] ports are used to take off
the hydraulic power for the hydraulic cylinder,
be sure to connect the [C] port to the head-end
side port of the hydraulic cylinder.
• Connect the colored coupler and the hydraulic
cylinder port as the following table when using
the control valve to take off the hydraulic power
for the hydraulic cylinder.
