Dump 2

1. When the hydraulic control lever is set to the 

"DUMP 2"

 position, the spool (4) of the bucket control section (2)

moves to the right of the bucket control section (2) moves further to the right from the 

"DUMP 1"

 position, which

forms oil passages between passage 2 (8) and 

A2

 port, and between 

B2

 port and 

T

 port.

2. The pressure-fed oil from the 

P

 port flows to the neutral passage 2 (5) through the boom control section (1) and

PB

 passage 1 (3). As the oil passage from the neutral passage 2 (5) to the 

PB

 passage 2 (6) is closed by the

spool (4), this oil opens the load check valve (7) and flows through the notched section of the spool (4) and 

B2

port to extend the bucket cylinder (9).

3. Return oil from the bucket cylinder (9) flows to the transmission case through the 

B2

 port and 

T

 port.
