OPERATIONEX35(C)/EX40(C)/EX45(C)/EX50(C)
(1) Double Acting Cylinder
2. To contract the cylinder, operate
the lever to the opposite position
of the expansion. Then, the hy-
draulic fluid is supplied from the
hydraulic pump to the hydraulic
port which is not connected, and
the pressure rises as the port is
blocked. However, this pressure is
released as the relief valve opens.

CONNECTING AND DISCONNECT-
ING IMPLEMENT HYDRAULIC HOSE
CONNECTION
1. Make sure to stop the engine be
-
fore connecting it.
2. Move the double acting valve le-
ver forward and backward for 4
to 5 times to release the pressure
in the hydraulic line of the tractor.
Otherwise, it is hard to connect
the couplers, and hydraulic fluid
can be sprayed from the line and
get in to your eyes while connect-
ing them.
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.

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 cylin-
der too frequently or for an ex-
tended period of time, the hy-
draulic fluid can be overheat-
ed, resulting in deterioration of
the hydraulic parts’ durability
as the main relief valve opens
at cylinder contraction.
3. When the cylinder is contracted,
the hydraulic fluid returned from
the cylinder is drained to the trans-
mission through the draining cir-
cuit as the operating lever is oper-
ated to the opposite direction from
the expansion position.
