OPERATION
CONNECTING AND DISCONNECTING IMPLEMENT HYDRAULIC HOSE
► CONNECTION ► DISCONNECTION
3. When the cylinder is contracted,
the hydraulic fluid returned from
the cylinder is drained to the trans-
mission through the draining circuit
as the operating lever is operated
to the opposite direction from the
expansion position.
IMPORTANT
It is recommended to use the
double acting cylinder instead
of the single acting cylinder if
the implement will be operated
frequently and continuously.
If using the single acting cyl-
inder too frequently or for an
extended period of time, the
hydraulic fluid can be over-
heated, resulting in deteriora-
tion of the hydraulic parts' du-
rability as the main relief valve
opens at cylinder contraction.

3. Remove any foreign material
around the couplers.
4. Keep the implement balanced by
removing any load applied (low-
ering it onto the ground, for ex-
ample). If disconnecting the hose
while outer load is applied to the
implement, it is hard to connect the
implement in the future.
3. Remove any foreign material
around the male and female cou-
plers. If foreign material enters the
hydraulic components, it can lead
to malfunction of the system.
4. Open the dust-proof cover of the
female coupler of the tractor and
insert the male coupler of the im-
plement. A clicking sound is heard
when the couplers are engaged.
5. Pull the hydraulic hose of the im-
plement to check that the couplers
are properly connected.
